Obesity: causes, consequences, treatments, and challenges

Obesity has become a global epidemic and is one of today’s most public health problems worldwide. Obesity poses a major risk for a variety of serious diseases including diabetes mellitus, non-alcoholic liver disease (NAFLD), cardiovascular disease, hypertension and stroke, and certain forms of cancer ( Bluher, 2019 ).

Obesity is mainly caused by imbalanced energy intake and expenditure due to a sedentary lifestyle coupled with overnutrition. Excess nutrients are stored in adipose tissue (AT) in the form of triglycerides, which will be utilized as nutrients by other tissues through lipolysis under nutrient deficit conditions. There are two major types of AT, white AT (WAT) and brown AT, the latter is a specialized form of fat depot that participates in non-shivering thermogenesis through lipid oxidation-mediated heat generation. While WAT has been historically considered merely an energy reservoir, this fat depot is now well known to function as an endocrine organ that produces and secretes various hormones, cytokines, and metabolites (termed as adipokines) to control systemic energy balance. Studies over the past decade also show that WAT, especially subcutaneous WAT, could undergo ‘beiging’ remodeling in response to environmental or hormonal perturbation. In the first paper of this special issue, Cheong and Xu (2021) systematically review the recent progress on the factors, pathways, and mechanisms that regulate the intercellular and inter-organ crosstalks in the beiging of WAT. A critical but still not fully addressed issue in the adipose research field is the origin of the beige cells. Although beige adipocytes are known to have distinct cellular origins from brown and while adipocytes, it remains unclear on whether the cells are from pre-existing mature white adipocytes through a transdifferentiation process or from de novo differentiation of precursor cells. AT is a heterogeneous tissue composed of not only adipocytes but also nonadipocyte cell populations, including fibroblasts, as well as endothelial, blood, stromal, and adipocyte precursor cells ( Ruan, 2020 ). The authors examined evidence to show that heterogeneity contributes to different browning capacities among fat depots and even within the same depot. The local microenvironment in WAT, which is dynamically and coordinately controlled by inputs from the heterogeneous cell types, plays a critical role in the beige adipogenesis process. The authors also examined key regulators of the AT microenvironment, including vascularization, the sympathetic nerve system, immune cells, peptide hormones, exosomes, and gut microbiota-derived metabolites. Given that increasing beige fat function enhances energy expenditure and consequently reduces body weight gain, identification and characterization of novel regulators and understanding their mechanisms of action in the beiging process has a therapeutic potential to combat obesity and its associated diseases. However, as noticed by the authors, most of the current pre-clinical research on ‘beiging’ are done in rodent models, which may not represent the exact phenomenon in humans ( Cheong and Xu, 2021 ). Thus, further investigations will be needed to translate the findings from bench to clinic.

While both social–environmental factors and genetic preposition have been recognized to play important roles in obesity epidemic, Gao et al. (2021) present evidence showing that epigenetic changes may be a key factor to explain interindividual differences in obesity. The authors examined data on the function of DNA methylation in regulating the expression of key genes involved in metabolism. They also summarize the roles of histone modifications as well as various RNAs such as microRNAs, long noncoding RNAs, and circular RNAs in regulating metabolic gene expression in metabolic organs in response to environmental cues. Lastly, the authors discuss the effect of lifestyle modification and therapeutic agents on epigenetic regulation of energy homeostasis. Understanding the mechanisms by which lifestyles such as diet and exercise modulate the expression and function of epigenetic factors in metabolism should be essential for developing novel strategies for the prevention and treatment of obesity and its associated metabolic diseases.

A major consequence of obesity is type 2 diabetes, a chronic disease that occurs when body cannot use and produce insulin effectively. Diabetes profoundly and adversely affects the vasculature, leading to various cardiovascular-related diseases such as atherosclerosis, arteriosclerotic, and microvascular diseases, which have been recognized as the most common causes of death in people with diabetes ( Cho et al., 2018 ). Love et al. (2021) systematically review the roles and regulation of endothelial insulin resistance in diabetes complications, focusing mainly on vascular dysfunction. The authors review the vasoprotective functions and the mechanisms of action of endothelial insulin and insulin-like growth factor 1 signaling pathways. They also examined the contribution and impart of endothelial insulin resistance to diabetes complications from both biochemical and physiological perspectives and evaluated the beneficial roles of many of the medications currently used for T2D treatment in vascular management, including metformin, thiazolidinediones, glucagon-like receptor agonists, dipeptidyl peptidase-4 inhibitors, sodium-glucose cotransporter inhibitors, as well as exercise. The authors present evidence to suggest that sex differences and racial/ethnic disparities contribute significantly to vascular dysfunction in the setting of diabetes. Lastly, the authors raise a number of very important questions with regard to the role and connection of endothelial insulin resistance to metabolic dysfunction in other major metabolic organs/tissues and suggest several insightful directions in this area for future investigation.

Following on from the theme of obesity-induced metabolic dysfunction, Xia et al. (2021) review the latest progresses on the role of membrane-type I matrix metalloproteinase (MT1-MMP), a zinc-dependent endopeptidase that proteolytically cleaves extracellular matrix components and non-matrix proteins, in lipid metabolism. The authors examined data on the transcriptional and post-translational modification regulation of MT1-MMP gene expression and function. They also present evidence showing that the functions of MT1-MMP in lipid metabolism are cell specific as it may either promote or suppress inflammation and atherosclerosis depending on its presence in distinct cells. MT1-MMP appears to exert a complex role in obesity for that the molecule delays the progression of early obesity but exacerbates obesity at the advanced stage. Because inhibition of MT1-MMP can potentially lower the circulating low-density lipoprotein cholesterol levels and reduce the risk of cancer metastasis and atherosclerosis, the protein has been viewed as a very promising therapeutic target. However, challenges remain in developing MT1-MMP-based therapies due to the tissue-specific roles of MT1-MMP and the lack of specific inhibitors for this molecule. Further investigations are needed to address these questions and to develop MT1-MMP-based therapeutic interventions.

Lastly, Huang et al. (2021) present new findings on a critical role of puromycin-sensitive aminopeptidase (PSA), an integral non-transmembrane enzyme that catalyzes the cleavage of amino acids near the N-terminus of polypeptides, in NAFLD. NAFLD, ranging from simple nonalcoholic fatty liver to the more aggressive subtype nonalcoholic steatohepatitis, has now become the leading chronic liver disease worldwide ( Loomba et al., 2021 ). At present, no effective drugs are available for NAFLD management in the clinic mainly due to the lack of a complete understanding of the mechanisms underlying the disease progress, reinforcing the urgent need to identify and validate novel targets and to elucidate their mechanisms of action in NAFLD development and pathogenesis. Huang et al. (2021) found that PSA expression levels were greatly reduced in the livers of obese mouse models and that the decreased PSA expression correlated with the progression of NAFLD in humans. They also found that PSA levels were negatively correlated with triglyceride accumulation in cultured hepatocytes and in the liver of ob/ob mice. Moreover, PSA suppresses steatosis by promoting lipogenesis and attenuating fatty acid β-oxidation in hepatocytes and protects oxidative stress and lipid overload in the liver by activating the nuclear factor erythroid 2-related factor 2, the master regulator of antioxidant response. These studies identify PSA as a pivotal regulator of hepatic lipid metabolism and suggest that PSA may be a potential biomarker and therapeutic target for treating NAFLD.

In summary, papers in this issue review our current knowledge on the causes, consequences, and interventions of obesity and its associated diseases such as type 2 diabetes, NAFLD, and cardiovascular disease ( Cheong and Xu, 2021 ; Gao et al., 2021 ; Love et al., 2021 ). Potential targets for the treatment of dyslipidemia and NAFLD are also discussed, as exemplified by MT1-MMP and PSA ( Huang et al., 2021 ; Xia et al., 2021 ). It is noted that despite enormous effect, few pharmacological interventions are currently available in the clinic to effectively treat obesity. In addition, while enhancing energy expenditure by browning/beiging of WAT has been demonstrated as a promising alternative approach to alleviate obesity in rodent models, it remains to be determined on whether such WAT reprogramming is effective in combating obesity in humans ( Cheong and Xu, 2021 ). Better understanding the mechanisms by which obesity induces various medical consequences and identification and characterization of novel anti-obesity secreted factors/soluble molecules would be helpful for developing effective therapeutic treatments for obesity and its associated medical complications.

The figure shows three maps of the U.S. with states color-coded based on the percent of the their population estimated to be obese. In 1990, all of the states are a blue color, indicating 10-14 percent of their populations were obese. In 2000, many states are a darker blue color, indicating 15-19 percent obesity, and about half of a beige color, indicating 20 to 24 percent obesity. In 2010, there are still some beige states but no blue ones, and many are orange or red, indicating 25 to 30+ percent obesity.

Since the 1980s, the prevalence of obesity in the United States has increased dramatically. Data collected by the Centers for Disease Control and Prevention show rising obesity across the nation, state-by-state. 1

The methods used by the CDC to collect the data changed in 2011, so we can’t make direct comparisons between the periods before and after that change, but the trend has continued. Every year, more and more people in the U.S. are obese.

A map of the U.S. showing obesity prevalence color-coded by state. States are about evenly split between green (20-25% obesity), yellow (25-30% obesity), or red (30-35% obesity).

These trends are unmistakable, and they’re not just occurring in adults. Childhood obesity has seen similar increases over the last few decades—perhaps an even greater concern as the metabolic and health effects of carrying too much weight can be compounded over a person’s entire lifetime.

A line graph shows the prevalence of obesity trending upwards between the years 1999-2000 and 2015-2016 in both children and adults. In this time span, the prevalence of obesity in children increased from 13.9 to 18.5 percent. In adults, it increased from 30.5 to 39.6 percent.

While obesity is a problem across the United States, it affects some groups of people more than others. Based on 2015-2016 data, obesity rates are higher among Hispanic (47 percent) and Black adults (47 percent) compared with white adults (38 percent). Non-Hispanic Asians have the lowest obesity rate (13 percent). And overall, people who are college-educated and have a higher income are less likely to be obese. 2  These health disparities point to the importance of looking at social context when examining causes and solutions. Not everyone has the same opportunity for good health, or an equal ability to make changes to their circumstances, because of factors like poverty and longstanding inequities in how resources are invested in communities. These factors are called “ social determinants of health. ” 3

The obesity epidemic is also not unique to the United States. Obesity is rising around the globe, and in 2015, it was estimated to affect 2 billion people worldwide, making it one of the largest factors affecting poor health in most countries . 4 Globally, among children aged 5 to 19 years old, the rate of overweight increased from 10.3 percent in 2000 to 18.4 percent in 2018. Previously, overweight and obesity mainly affected high-income countries, but some of the most dramatic increases in childhood overweight over the last decade have been in low income countries, such as those in Africa and South Asia, corresponding to a greater availability of inexpensive, processed foods. 5

Despite the gravity of the problem, no country has yet been able to implement policies that have reversed the trend and brought about a decrease in obesity. This represents “one of the biggest population health failures of our time,” wrote an international group of researchers in the journal The Lancet in 2019. 6  The World Health Organization has set a target of stopping the rise of obesity by 2025. Doing so requires understanding what is causing the obesity epidemic; it is only when these causes are addressed that change can start to occur.

Causes of the Obesity Epidemic

If obesity was an infectious disease sweeping the globe, affecting billions of people’s health, longevity, and productivity, we surely would have addressed it by now. Researchers and pharmaceutical companies would have worked furiously to develop vaccines and medicines to prevent and cure this disease. But the causes of obesity are much more complex than a single bacteria or virus, and solving this problem means recognizing and addressing a multitude of factors that lead to weight gain in a population.

At its core, rising obesity is caused by a chronic shift towards positive energy balance—consuming more energy or calories than one expends each day, leading to an often gradual but persistent increase in body weight. People often assume that this is an individual problem, that those who weigh more simply need to change their behavior to eat less and exercise more, and if this doesn’t work, it must be because of a personal failing, such as a lack of self-control or motivation. While behavior patterns such as diet and exercise can certainly impact a person’s risk of developing obesity (as we’ll cover later in this chapter), the environments where we live also have a big impact on our behavior and can make it much harder to maintain energy balance.

Environment

Many of us live in what researchers and public health experts call “ obesogenic environments. ” That is, the ways in which our neighborhoods are built and our lives are structured influence our physical activity and food intake to encourage weight gain. 7 Human physiology and metabolism evolved in a world where obtaining enough food for survival required significant energy investment in hunting or gathering—very different from today’s world where more people earn their living in sedentary occupations. From household chores, to workplace productivity, to daily transportation, getting things done requires fewer calories than it did in past generations.

The image shows three photos. Left to right: a group of well-dressed Black women sit at a work conference table, with laptops in front of them; 4 vending machines sell snacks and soft drinks; and cars jamming a freeway.

Our jobs have become more and more sedentary, with fewer opportunities for non-exercise thermogenesis (NEAT) throughout the day. There’s less time in the school day for recess and physical activity, and fears about neighborhood safety limit kids’ ability to get out and play after the school day is over. Our towns and cities are built more for cars than for walking or biking. We can’t turn back the clock on human progress, and finding a way to stay healthy in obesogenic environments is a significant challenge.

Our environments can also impact our food choices. We’re surrounded by vending machines, fast food restaurants, coffeeshops, and convenience stores that offer quick and inexpensive access to calories. These foods are also heavily advertised, and especially when people are stretched thin by working long hours or multiple jobs, they can be a welcome convenience. However, they tend to be calorie-dense (and less nutrient-dense) and more heavily processed, with amounts of sugar, fat, and salt optimized to make us want to eat more, compared with home-cooked food. In addition, portion sizes at restaurants, especially fast food chains, have increased over the decades, and people are eating at restaurants more and cooking at home less.

Poverty and Food Insecurity

Living in poverty usually means living in a more obesogenic environment. Consider the fact that some of the poorest neighborhoods in the United States—with some of the highest rates of obesity—are often not safe or pleasant places to walk, play, or exercise. They may have busy traffic and polluted air, and they may lack sidewalks, green spaces, and playgrounds. A person living in this type of neighborhood will find it much more challenging to get adequate physical activity compared with someone living in a neighborhood where it’s safe to walk to school or work, play at a park, ride a bike, or go for a run.

In addition, poor neighborhoods often lack a grocery store where people can purchase fresh fruits and vegetables and basic ingredients necessary for cooking at home. Such areas are called “ food deserts ”—where healthy foods simply aren’t available or easily accessible.

Another concept useful in discussions of obesity risk is “food insecurity.”  Food security  means “access by all people at all times to enough food for an active, healthy life.” 8  Food insecurity  means an inability to consistently obtain adequate food. It may seem counter-intuitive, but in the United States, food insecurity is linked to obesity. That is, people who have difficulty obtaining enough food are more likely to become obese and to suffer from diabetes and hypertension. This is likely related to the fact that inexpensive foods tend to be high in calories but low in nutrients, and when these foods form the foundation of a person’s diet, they can cause both obesity and nutrient deficiencies. It’s estimated that 12 percent of U.S. households are food insecure, and food insecurity is higher among Black (22 percent) and Latino (18 percent) households. 3

What about genetics? While it’s true that our genes can influence our susceptibility to becoming obese, researchers say they can’t be a cause of the obesity epidemic. Genes take many generations to evolve, and the obesity epidemic has occurred over just the last 40 to 50 years—only a few generations. When our grandparents were children, they were much less likely to become obese than our own children. That’s not because their genes were different, but rather because they grew up in a different environment. However, it is true that a person’s genes can influence their susceptibility to becoming obese in this obesogenic environment, and obesity is more prevalent in some families. A person’s genetic make-up can make it more difficult to maintain energy balance in an obesogenic environment, because certain genes may make you feel more hungry or slow your energy expenditure. 2

Solutions to the Obesity Epidemic

Given the multiple causes of obesity, solving this problem will also require many solutions at different levels. Because obesity affects people over the lifespan and is difficult to reverse, the focus of many of these efforts is prevention, starting as early as the first years of life. We’ll discuss individual weight management strategies later in this chapter. Here, we’ll review some strategies happening in schools, communities, and at the state and federal levels.

Support Healthy Dietary Patterns

Interventions that support healthy dietary patterns, especially among people more vulnerable because of food insecurity or poverty, may reduce obesity. In some cases, studies have shown that they have an impact, and in other cases, it’s too soon to know. Here are some examples:

  • Implement and support better nutrition standards for childcare, schools, hospitals, and worksites. 9
  • Limit marketing of processed foods, especially ads targeted towards children.
  • Provide incentives for supermarkets or farmers markets to establish businesses in underserved areas. 9

On the right, a closeup of a farmers' market stand, showing enticing fresh vegetables like carrots, cucumbers, tomatoes, and beets.

Figure 9.21. Farmers markets can expand healthy food options for neighborhoods and build connections between consumers and local farmers.

  • Place nutrition and calorie content on restaurant and fast food menus to raise awareness of food choices. 9 Beginning in 2018, as part of the Affordable Care Act, chain restaurants with more than 20 locations were required to add calorie information to their menus, and some had already done so voluntarily. There isn’t yet enough research to say whether having this information improves customers’ choices; some studies show an effect and others don’t. 10 Many factors influence people’s decisions, and the type of restaurant, customer needs, and menu presentation all likely matter. For example, some studies show that health-conscious consumers choose lower calorie menu items when presented with nutrition information, but people with food insecurity may understandably choose higher calorie items to get more “bang for their buck”. 11 Research has also shown that adding interpretative images—like a stoplight image labeling menu choices as green or red as shorthand for high or low nutrient density—can help. And a 2018 study found that when calorie counts are on the left side of English-language menus, people order lower-calorie menu items. Putting calorie counts on the right side of the menu (as is more common) doesn’t have this effect, likely because the English language is read from left to right. 12 Some studies have also found that restaurants that implement menu labeling offer lower-calorie and more nutrient-dense options, indicating that menu labeling may push restaurants to look more closely at the food they serve. 10,13

  • Increase access to food assistance programs and align them with nutrition recommendations. For example, in 2009, the U.S. Department of Agriculture revised the food packages for the Women, Infants, and Children (WIC) program to better align with the Dietary Guidelines for Americans. The new packages emphasized more fruits, vegetables, whole grains, and low-fat dairy and decreased the availability of juice. After this change, there was a decrease in the obesity rate of children in the WIC program. Similar progress may be made by increasing access to the Supplemental Nutrition Assistance Program (SNAP) in order to reduce food insecurity. Many farmers’ markets now accept SNAP benefits for the purchase of fresh fruit and vegetables. 3
  • Tax sugary drinks, such as soda and sports drinks, which contribute significant empty calories to the U.S. diet and are associated with childhood obesity. Local taxes on soda and other sugary drinks are often controversial, and soda companies lobby to prevent them from passing. However, early research in U.S. cities with soda taxes show that they do work to decrease soda consumption. 3 In the U.S., soda has only been taxed at the local level, and the tax has been paid by consumers. The United Kingdom has taken a different approach: They started taxing soft drink manufacturers for the sugar content of the products they sell. Between 2015 and 2018, the average sugar content of soda sold in the U.K. dropped by 29 percent. 14

Support Greater Physical Activity

Increasing physical activity increases the energy expended during the day. This can help maintain energy balance, thus preventing weight gain. It may also help to shift a person into negative energy balance and facilitate weight loss if needed. But simply adding an exercise session—a run or a trip to the gym, say—often doesn’t shift energy balance (though it’s certainly good for health). Why? Exercise can increase hunger, and there’s only so many calories a person can burn in 30 or 60 minutes. That’s why it’s also important to look for opportunities for non-exercise activity thermogenesis (NEAT); that is, find ways to increase movement throughout the day.

  • P rioritize physical education and recess time in schools. In addition to helping kids stay healthy, movement also helps them learn.  
  • Make neighborhoods safer and more accessible for walking, cycling, and playing.
  • When safe, encourage kids to walk or bike to school.
  • Build family and community activities around physical activity, such as trips to the park, walks together, and community walking and exercise groups.
  • Facilitate more movement in the workday by encouraging walking meetings, movement breaks, and treadmill desks.
  • Find ways to move that are enjoyable to you and fit your life. Yard work, walking your dog, playing tag with your kids, and going out dancing all count!

What is Obesity

What is obesity? Obesity and BMI (body mass index) are both tools of measurement that are used by doctors to assess body fat according to the height, age, and gender of a person. If the BMI is between 25 to 29.9, that means the person has excess weight and body fat.

If the BMI exceeds 30, that means the person is obese. Obesity is a condition that increases the risk of developing cardiovascular diseases, high blood pressure, and other medical conditions like metabolic syndrome, arthritis, and even some types of cancer.

Obesity Definition

Obesity is defined by the World Health Organization as an accumulation of abnormal and excess body fat that comes with several risk factors. It is measured by the body mass index BMI, body weight (in kilograms) divided by the square of a person’s height (in meters).

Obesity in America

Obesity is on the verge of becoming an epidemic as 1 in every 3 Americans can be categorized as overweight and obese. Currently, America is an obese country, and it continues to get worse.

Obesity as a Worldwide Problem and Its Solution Essay

Introduction, what exactly is obesity, reasons of obesity, healthy eating habits – the only solution, survey page.

The progress of a nation solely rests on the citizens. Of greater significance are their socio-economic, political conditions. A huge sum is spent every year by the government for the welfare of the subjects. With the change in policies every year, a novel decision is taken up. These decisions cater to individual interests in the larger interest of society in general.

Unfortunately, the world now witnesses an unhealthy scenario caused due to socio-economic, political imbalances. They affect the physical and mental health of individuals. Perhaps, one of the most glaring problems of the day seems to be obesity. Once, considered a symbol of wealth and social status, physical attractiveness, strength, and fertility by certain European cultures, western culture takes a negative stand on it. The obese are unattractive and negative stereotypes. They are a social stigma, targets of bullies, and shunned by peers. Above all, obesity is seen as a sign of lower socioeconomic status, more a medical condition in modern western culture. Ironically, the USA accounts for 64.5% of its population either overweight or obese.

The Times America has reported, “It’s not healthy to be obese, and if we keep going the way we are headed, the long-term medical costs may be more than we can bear” (Americas Obesity Crisis, 2004).

The problem of obesity is a worldwide issue that needs due attention. It has been medically proved that obesity could be fatal. What exactly is obesity? “The natural energy reserve, stored in the fatty tissue of human and other mammals is increased to a point where it is associated with certain health conditions or increased mortality. It is viewed as a serious and growing health problem which gives birth to certain other diseases like cardiovascular diseases, diabetes mellitus type 2, sleep apnea and osteoarthritis” (Obesity, 2008).

Visit: www win.niddk.gov/publications/health_risks.htm# sleep for more information on the relationship between sleep apnea and obesity.

BMI (body mass index) is a widely used method for estimating body fat. Calculated by dividing the subject’s weight by the square of his/her height, typically expressed either in metric or US “Customary” units, a frightening score could take away the cheer from every face.

The dreaded physical condition has umpteen reasons for its attack, the main being a sedentary lifestyle. The last quarter of the 20th century has witnessed a rapid acceleration of obesity in western society. Hence, it remains a persistent problem.

To arrive at a definite reason for a large number of obese in a nation, it would be sufficient to note the patterns of lifestyles of each individual. It would also suffice if the socio-economic conditions are taken into consideration. It would be wise to elaborate on the principal causes of this condition and arrive at a suitable solution to it.

The primary reason is we have seen earlier is an increasingly sedentary lifestyle and lack of activity. This causes the deposits of excess fat principally in the abdomen areas and hence enlargements of muscles concerned. Yet another reason could be the lower relative cost of foodstuffs. This enables people of all walks of life to take in food whether necessary or unnecessary. Increased marketing, accounts for the innumerable stock of junk food, preferred by children and adults alike. In two-income households, the clock never ticks in the kitchen, the occupants never bother to take care of their health. Food is often taken from restaurants where delicious and sumptuous food three or more times a day causes unhealthy eating habits.

Regular exercise and eating right are considered to be the best solution to the problem. Exercise requires energy (calories) stored as body fat. The body breaks down its fat stored to provide energy during prolonged aerobic exercise. Medical help ranging from pills to surgery is recommended in certain extreme cases of obesity. The probable reasons could be thyroid malfunction or other organ dysfunction.

It is the only problem that needs immediate remedy as the sufferers not only undergo physical torture but also mental anguish. In the years to come, a significant number of Americans could turn against themselves and the results could lead to disaster and deaths. I could sound embarrassing. But there is enough evidence to prove that the silent sufferers end up taking their own lives due to social pressures and inhospitable environment.

Concrete measures in this direction must be enforced by the government. Citizens should be given proper guidance. Measures to enhance awareness should be designed.

It is pathetic that America, the world’s most developed country has the ‘smallest fund of practical nutritional knowledge’ (Obesity in America).

To illustrate this point, Dr. Dean Ornish. M.D- Cardiologist said in an interview, “I’d love to be able to tell people that bacon and eggs are health food, but they are not.” “An easier way a fewer calorie is not just to change the amount of food but the type of food, because fat has 9 calories per gram, whereas protein and carbohydrates have only 4. So when you eat less fat, you eat fewer calories without having to eat less food.” (Interview Dean Ornish, M. D, 2004).

Dr. Ornish’s book Eat More, Weigh Less is based on this concept.

His method has been scientifically proven because it is based on abundance rather than on deprivation.

“You can eat when you’re hungry, you can eat until you’re full, and you still lose weight and keep it off…..” (Ornish).

Dr.Ornish further claims that his diet has been proven to stop or reduce heart disease and has been backed up by scientific studies. His claim and findings cannot be written off as our ancestors led a healthy life as they fed on food coming directly from the land. Obesity wasn’t even a word.

With modern technology, change in American diet and lifestyle, eating fast food, microwave dinners, and a diet of packaged, processed, and refined foods, the American finds himself digging his own grave. People with determination and a will to survive have succeeded in being healthy again. Alas! The number of such people is only a handful. Inevitably, processed food, fast foods, meat products, high sugar, and high sodium food have to be substituted by whole grains, vegetables, fruits, and legumes.

To substantiate the above statement, Nathan Sorensen, a leading dietician has outlined 10 important tips for a healthy eating habit.

  • Eat breakfast daily.
  • Plan your daily meals.
  • Pack a fruit snack for the commute.
  • Choose the smaller portion food entrée’s, if you eat out for lunch.
  • Eat a snack when you get home; tortillas with salsa.
  • Before grocery shopping, write a shopping list.
  • Plan and prepare fish and vegetable meals weekly.
  • Choose not to add fat to prepared foods.
  • Eat dinner every night before 7.30P.M.
  • Have a snack an hour or so before food. (Sorensen, 2008).

There have been innumerable articles, journals, and books written on this concern. Medical science has advanced to such an extent that it can provide a remedy to almost all ailments. Health is probably the only field wherein the individual has to equip himself before approaching his specialist on his predicament. The most important factor seems to be willpower and self- control. Yet another fact is a change in his lifestyle. The doctor is only a medium through which the individual can find a solution to his ailment, but the ultimate cure lies in the hands of the patient.

A nation can be adjudged the best by the quality of its products, its approach on the socio-economic and political fronts, individual expertise, and above all health. America stands ahead of all the nations in the world in all the above respects except, general health. This problem has assumed a gigantic proportion which requires total co-operation to the reduction of its size. By total co-operation, I mean the individual, the market, the government, and medical science sitting together to arrive at an amicable solution.

To show the depth of the gravity of the situation, a survey was conducted and the results obtained was quite alarming. Nearly, 65% of adults in America are prone to obesity due to circumstances of the modern man’s life.

The percent obese graph listed below supports the view.

Age group 1991 1995 1998 2000 2001

An alarming upward trend is seen. (Obesity Trends, 1991-2003).

The US has the highest rate of obesity in the developed world. In 2004, the CDC reported that 66.3% of the adults in the US are overweight or obese. True but unbelievable, a stressful mentally and insufficient sleep could also result in obesity. Genetic reasons seem to be silent killers in this direction.

Let’s take a look…

100 Words Essay on Obesity Cause And Solution

What is obesity.

Obesity is when a person has too much body fat. It’s not just about looking big; it’s a health issue. Doctors can tell if someone is obese by measuring their body mass index (BMI). A high BMI means a higher risk of getting sick from obesity.

Causes of Obesity

Obesity happens for many reasons. Eating too much, especially junk food, is a big cause. Not moving enough, like sitting all day, also leads to weight gain. Sometimes, it’s in the family, and other times, it’s because of emotional stress.

Finding Solutions

To fight obesity, eat healthy food like fruits and vegetables. Exercise is important too; playing sports or even walking helps. Limiting screen time and not eating too much candy and fast food can also make a big difference.

250 Words Essay on Obesity Cause And Solution

What causes obesity.

Obesity is when a person has too much body fat. It can happen for many reasons. Eating too much food, especially junk food like chips, soda, and sweets, is a big cause. These foods have lots of calories, which is like fuel for the body, but if you don’t burn it off with activities, it turns into fat. Not moving around enough is another reason. If you sit all day and don’t play or exercise, your body can’t use up the food you eat.

Genes and Health Issues

Sometimes, it’s not just about food or exercise. Your family’s genes can make you more likely to get heavy. Some kids have health problems that make gaining weight easy and losing it hard. It’s important to know if your weight is because of these issues.

What Can We Do About It?

First, eat healthy. Choose fruits, veggies, and lean meats like chicken or fish. Drink water instead of sugary drinks. Second, be active. Play sports, dance, or just go for a walk. It’s fun and good for you.

Getting Help

If you’re worried about your weight, talk to a grown-up. Doctors and nutritionists can give good advice. They can help you make a plan to eat better and move more. It’s not about being skinny; it’s about being healthy. Remember, change takes time, so be patient and keep trying.

500 Words Essay on Obesity Cause And Solution

Understanding obesity.

Obesity is a health condition where a person has a lot of extra body fat. It’s like carrying around a heavy backpack all the time, which can make it hard to do everyday activities and can lead to health problems.

Why Do People Become Obese?

People become obese for many reasons. One big reason is eating too much food that has a lot of calories. Calories are like fuel for our bodies, but if we get more than we need, our bodies store it as fat. Foods like candy, cakes, and fast food are high in calories.

Not moving around enough is another reason. Our bodies are made to move, but if we sit around a lot and don’t exercise, we don’t burn off the extra calories, which can lead to weight gain.

Sometimes, it’s not just about food and exercise. Things like not getting enough sleep, feeling stressed, or having a health condition can make it easier to gain weight. Also, if your family members are obese, you might be more likely to become obese too.

Health Problems from Obesity

Carrying too much weight can cause health issues. It can make it hard to breathe, walk, or play sports. It can also lead to serious problems like diabetes, heart disease, and joint pain. These issues can make life tough and less enjoyable.

Finding Solutions to Obesity

To fight obesity, we need to focus on eating better and moving more. Eating better means choosing fruits, vegetables, whole grains, and lean meats instead of high-calorie junk food. It’s like picking a team of superheroes for your body that will help you stay healthy and strong.

Moving more can be fun. It’s not just about doing push-ups or running. You can dance, play sports, ride a bike, or even just walk more. The goal is to be active for at least an hour every day.

Help from Family and Friends

Dealing with obesity is easier when you have support. Families can help by cooking healthy meals and finding fun ways to be active together. Friends can encourage each other to make good choices and stick to them.

The Role of Schools and Communities

Schools and communities play a big part too. Schools can provide healthy meals and make sure kids get time to play and move during the day. Communities can create safe places to play and offer programs that teach about healthy living.

Obesity is a big problem, but it’s one we can solve. By eating right, staying active, getting support, and working together, we can help everyone live healthier and happier lives. Remember, small steps can lead to big changes, so let’s start now and make a difference!

That’s it! I hope the essay helped you.

Obesity is a chronic health condition in which the body fat reaches abnormal level. Obesity occurs when we consume much more amount of food than our body really needs on a daily basis. In other words, when the intake of calories is greater than the calories we burn out, it gives rise to obesity.

Audience: The below given essays are exclusively written for school students (Class 5, 6, 7, 8, 9, 10, 11 and 12 Standard), college, science and medical students.

Introduction:

Obesity means being excessively fat. A person would be said to be obese if his or her body mass index is beyond 30. Such a person has a body fat rate that is disproportionate to his body mass.

Obesity and the Body Mass Index:

The body mass index is calculated considering the weight and height of a person. Thus, it is a scientific way of determining the appropriate weight of any person. When the body mass index of a person indicates that he or she is obese, it exposes the person to make health risk.

Stopping Obesity:

There are two major ways to get the body mass index of a person to a moderate rate. The first is to maintain a strict diet. The second is to engage in regular physical exercise. These two approaches are aimed at reducing the amount of fat in the body.

Conclusion:

Obesity can lead to sudden death, heart attack, diabetes and may unwanted illnesses. Stop it by making healthy choices.

Obesity has become a big concern for the youth of today’s generation. Obesity is defined as a medical condition in which an individual gains excessive body fat. When the Body Mass Index (BMI) of a person is over 30, he/ she is termed as obese.

Obesity can be a genetic problem or a disorder that is caused due to unhealthy lifestyle habits of a person. Physical inactivity and the environment in which an individual lives, are also the factors that leads to obesity. It is also seen that when some individuals are in stress or depression, they start cultivating unhealthy eating habits which eventually leads to obesity. Medications like steroids is yet another reason for obesity.

Obesity has several serious health issues associated with it. Some of the impacts of obesity are diabetes, increase of cholesterol level, high blood pressure, etc. Social impacts of obesity includes loss of confidence in an individual, lowering of self-esteem, etc.

The risks of obesity needs to be prevented. This can be done by adopting healthy eating habits, doing some physical exercise regularly, avoiding stress, etc. Individuals should work on weight reduction in order to avoid obesity.

Obesity is indeed a health concern and needs to be prioritized. The management of obesity revolves around healthy eating habits and physical activity. Obesity, if not controlled in its initial stage can cause many severe health issues. So it is wiser to exercise daily and maintain a healthy lifestyle rather than being the victim of obesity.

Obesity can be defined as the clinical condition where accumulation of excessive fat takes place in the adipose tissue leading to worsening of health condition. Usually, the fat is deposited around the trunk and also the waist of the body or even around the periphery.

Obesity is actually a disease that has been spreading far and wide. It is preventable and certain measures are to be taken to curb it to a greater extend. Both in the developing and developed countries, obesity has been growing far and wide affecting the young and the old equally.

The alarming increase in obesity has resulted in stimulated death rate and health issues among the people. There are several methods adopted to lose weight and they include different diet types, physical activity and certain changes in the current lifestyle. Many of the companies are into minting money with the concept of inviting people to fight obesity.

In patients associated with increased risk factor related to obesity, there are certain drug therapies and other procedures adopted to lose weight. There are certain cost effective ways introduced by several companies to enable clinic-based weight loss programs.

Obesity can lead to premature death and even cause Type 2 Diabetes Mellitus. Cardiovascular diseases have also become the part and parcel of obese people. It includes stroke, hypertension, gall bladder disease, coronary heart disease and even cancers like breast cancer, prostate cancer, endometrial cancer and colon cancer. Other less severe arising due to obesity includes osteoarthritis, gastro-esophageal reflux disease and even infertility.

Hence, serious measures are to be taken to fight against this dreadful phenomenon that is spreading its wings far and wide. Giving proper education on benefits of staying fit and mindful eating is as important as curbing this issue. Utmost importance must be given to healthy eating habits right from the small age so that they follow the same until the end of their life.

Obesity is majorly a lifestyle disease attributed to the extra accumulation of fat in the body leading to negative health effects on a person. Ironically, although prevalent at a large scale in many countries, including India, it is one of the most neglect health problems. It is more often ignored even if told by the doctor that the person is obese. Only when people start acquiring other health issues such as heart disease, blood pressure or diabetes, they start taking the problem of obesity seriously.

Obesity Statistics in India:

As per a report, India happens to figure as the third country in the world with the most obese people. This should be a troubling fact for India. However, we are yet to see concrete measures being adopted by the people to remain fit.

Causes of Obesity:

Sedentary lifestyle, alcohol, junk food, medications and some diseases such as hypothyroidism are considered as the factors which lead to obesity. Even children seem to be glued to televisions, laptops and video games which have taken away the urge for physical activities from them. Adding to this, the consumption of junk food has further aggravated the growing problem of obesity in children.

In the case of adults, most of the professions of today make use of computers which again makes people sit for long hours in one place. Also, the hectic lifestyle of today makes it difficult for people to spare time for physical activities and people usually remain stressed most of the times. All this has contributed significantly to the rise of obesity in India.

Obesity and BMI:

Body Mass Index (BMI) is the measure which allows a person to calculate how to fit he or she is. In other words, the BMI tells you if you are obese or not. BMI is calculated by dividing the weight of a person in kg with the square of his / her height in metres. The number thus obtained is called the BMI. A BMI of less than 25 is considered optimal. However, if a person has a BMI over 30 he/she is termed as obese.

What is a matter of concern is that with growing urbanisation there has been a rapid increase of obese people in India? It is of utmost importance to consider this health issue a serious threat to the future of our country as a healthy body is important for a healthy soul. We should all be mindful of what we eat and what effect it has on our body. It is our utmost duty to educate not just ourselves but others as well about this serious health hazard.

Obesity can be defined as a condition (medical) that is the accumulation of body fat to an extent that the excess fat begins to have a lot of negative effects on the health of the individual. Obesity is determined by examining the body mass index (BMI) of the person. The BMI is gotten by dividing the weight of the person in kilogram by the height of the person squared.

When the BMI of a person is more than 30, the person is classified as being obese, when the BMI falls between 25 and 30, the person is said to be overweight. In a few countries in East Asia, lower values for the BMI are used. Obesity has been proven to influence the likelihood and risk of many conditions and disease, most especially diabetes of type 2, cardiovascular diseases, sleeplessness that is obstructive, depression, osteoarthritis and some cancer types.

In most cases, obesity is caused through a combination of genetic susceptibility, a lack of or inadequate physical activity, excessive intake of food. Some cases of obesity are primarily caused by mental disorder, medications, endocrine disorders or genes. There is no medical data to support the fact that people suffering from obesity eat very little but gain a lot of weight because of slower metabolism. It has been discovered that an obese person usually expends much more energy than other people as a result of the required energy that is needed to maintain a body mass that is increased.

It is very possible to prevent obesity with a combination of personal choices and social changes. The major treatments are exercising and a change in diet. We can improve the quality of our diet by reducing our consumption of foods that are energy-dense like those that are high in sugars or fat and by trying to increase our dietary fibre intake.

We can also accompany the appropriate diet with the use of medications to help in reducing appetite and decreasing the absorption of fat. If medication, exercise and diet are not yielding any positive results, surgery or gastric balloon can also be carried out to decrease the volume of the stomach and also reduce the intestines’ length which leads to the feel of the person get full early or a reduction in the ability to get and absorb different nutrients from a food.

Obesity is the leading cause of ill-health and death all over the world that is preventable. The rate of obesity in children and adults has drastically increased. In 2015, a whopping 12 percent of adults which is about 600 million and about 100 million children all around the world were found to be obese.

It has also been discovered that women are more obese than men. A lot of government and private institutions and bodies have stated that obesity is top of the list of the most difficult and serious problems of public health that we have in the world today. In the world we live today, there is a lot of stigmatisation of obese people.

We all know how troubling the problem of obesity truly is. It is mainly a form of a medical condition wherein the body tends to accumulate excessive fat which in turn has negative repercussions on the health of an individual.

Given the current lifestyle and dietary style, it has become more common than ever. More and more people are being diagnosed with obesity. Such is its prevalence that it has been termed as an epidemic in the USA. Those who suffer from obesity are at a much higher risk of diabetes, heart diseases and even cancer.

In order to gain a deeper understanding of obesity, it is important to learn what the key causes of obesity are. In a layman term, if your calorie consumption exceeds what you burn because of daily activities and exercises, it is likely to lead to obesity. It is caused over a prolonged period of time when your calorie intake keeps exceeding the calories burned.

Here are some of the key causes which are known to be the driving factors for obesity.

If your diet tends to be rich in fat and contains massive calorie intake, you are all set to suffer from obesity.

Sedentary Lifestyle:

With most people sticking to their desk jobs and living a sedentary lifestyle, the body tends to get obese easily.

Of course, the genetic framework has a lot to do with obesity. If your parents are obese, the chance of you being obese is quite high.

The weight which women gain during their pregnancy can be very hard to shed and this is often one of the top causes of obesity.

Sleep Cycle:

If you are not getting an adequate amount of sleep, it can have an impact on the hormones which might trigger hunger signals. Overall, these linked events tend to make you obese.

Hormonal Disorder:

There are several hormonal changes which are known to be direct causes of obesity. The imbalance of the thyroid stimulating hormone, for instance, is one of the key factors when it comes to obesity.

Now that we know the key causes, let us look at the possible ways by which you can handle it.

Treatment for Obesity:

As strange as it may sound, the treatment for obesity is really simple. All you need to do is follow the right diet and back it with an adequate amount of exercise. If you can succeed in doing so, it will give you the perfect head-start into your journey of getting in shape and bidding goodbye to obesity.

There are a lot of different kinds and styles of diet plans for obesity which are available. You can choose the one which you deem fit. We recommend not opting for crash dieting as it is known to have several repercussions and can make your body terribly weak.

The key here is to stick to a balanced diet which can help you retain the essential nutrients, minerals, and, vitamins and shed the unwanted fat and carbs.

Just like the diet, there are several workout plans for obesity which are available. It is upon you to find out which of the workout plan seems to be apt for you. Choose cardio exercises and dance routines like Zumba to shed the unwanted body weight. Yoga is yet another method to get rid of obesity.

So, follow a blend of these and you will be able to deal with the trouble of obesity in no time. We believe that following these tips will help you get rid of obesity and stay in shape.

Obesity and overweight is a top health concern in the world due to the impact it has on the lives of individuals. Obesity is defined as a condition in which an individual has excessive body fat and is measured using the body mass index (BMI) such that, when an individual’s BMI is above 30, he or she is termed obese. The BMI is calculated using body weight and height and it is different for all individuals.

Obesity has been determined as a risk factor for many diseases. It results from dietary habits, genetics, and lifestyle habits including physical inactivity. Obesity can be prevented so that individuals do not end up having serious complications and health problems. Chronic illnesses like diabetes, heart diseases and relate to obesity in terms of causes and complications.

Factors Influencing Obesity:

Obesity is not only as a result of lifestyle habits as most people put it. There are other important factors that influence obesity. Genetics is one of those factors. A person could be born with genes that predispose them to obesity and they will also have difficulty in losing weight because it is an inborn factor.

The environment also influences obesity because the diet is similar in certain environs. In certain environments, like school, the food available is fast foods and the chances of getting healthy foods is very low, leading to obesity. Also, physical inactivity is an environmental factor for obesity because some places have no fields or tracks where people can jog or maybe the place is very unsafe and people rarely go out to exercise.

Mental health affects the eating habits of individuals. There is a habit of stress eating when a person is depressed and it could result in overweight or obesity if the person remains unhealthy for long period of time.

The overall health of individuals also matter. If a person is unwell and is prescribed with steroids, they may end up being obese. Steroidal medications enable weight gain as a side effect.

Complications of Obesity:

Obesity is a health concern because its complications are severe. Significant social and health problems are experienced by obese people. Socially, they will be bullied and their self-esteem will be low as they will perceive themselves as unworthy.

Chronic illnesses like diabetes results from obesity. Diabetes type 2 has been directly linked to obesity. This condition involves the increased blood sugars in the body and body cells are not responding to insulin as they should. The insulin in the body could also be inadequate due to decreased production. High blood sugar concentrations result in symptoms like frequent hunger, thirst and urination. The symptoms of complicated stages of diabetes type 2 include loss of vision, renal failure and heart failure and eventually death. The importance of having a normal BMI is the ability of the body to control blood sugars.

Another complication is the heightened blood pressures. Obesity has been defined as excessive body fat. The body fat accumulates in blood vessels making them narrow. Narrow blood vessels cause the blood pressures to rise. Increased blood pressure causes the heart to start failing in its physiological functions. Heart failure is the end result in this condition of increased blood pressures.

There is a significant increase in cholesterol in blood of people who are obese. High blood cholesterol levels causes the deposition of fats in various parts of the body and organs. Deposition of fats in the heart and blood vessels result in heart diseases. There are other conditions that result from hypercholesterolemia.

Other chronic illnesses like cancer can also arise from obesity because inflammation of body cells and tissues occurs in order to store fats in obese people. This could result in abnormal growths and alteration of cell morphology. The abnormal growths could be cancerous.

Management of Obesity:

For the people at risk of developing obesity, prevention methods can be implemented. Prevention included a healthy diet and physical activity. The diet and physical activity patterns should be regular and realizable to avoid strains that could result in complications.

Some risk factors for obesity are non-modifiable for example genetics. When a person in genetically predisposed, the lifestyle modifications may be have help.

For the individuals who are already obese, they can work on weight reduction through healthy diets and physical exercises.

In conclusion, obesity is indeed a major health concern because the health complications are very serious. Factors influencing obesity are both modifiable and non-modifiable. The management of obesity revolves around diet and physical activity and so it is important to remain fit.

In olden days, obesity used to affect only adults. However, in the present time, obesity has become a worldwide problem that hits the kids as well. Let’s find out the most prevalent causes of obesity.

Factors Causing Obesity:

Obesity can be due to genetic factors. If a person’s family has a history of obesity, chances are high that he/ she would also be affected by obesity, sooner or later in life.

The second reason is having a poor lifestyle. Now, there are a variety of factors that fall under the category of poor lifestyle. An excessive diet, i.e., eating more than you need is a definite way to attain the stage of obesity. Needless to say, the extra calories are changed into fat and cause obesity.

Junk foods, fried foods, refined foods with high fats and sugar are also responsible for causing obesity in both adults and kids. Lack of physical activity prevents the burning of extra calories, again, leading us all to the path of obesity.

But sometimes, there may also be some indirect causes of obesity. The secondary reasons could be related to our mental and psychological health. Depression, anxiety, stress, and emotional troubles are well-known factors of obesity.

Physical ailments such as hypothyroidism, ovarian cysts, and diabetes often complicate the physical condition and play a massive role in abnormal weight gain.

Moreover, certain medications, such as steroids, antidepressants, and contraceptive pills, have been seen interfering with the metabolic activities of the body. As a result, the long-term use of such drugs can cause obesity. Adding to that, regular consumption of alcohol and smoking are also connected to the condition of obesity.

Harmful Effects of Obesity:

On the surface, obesity may look like a single problem. But, in reality, it is the mother of several major health issues. Obesity simply means excessive fat depositing into our body including the arteries. The drastic consequence of such high cholesterol levels shows up in the form of heart attacks and other life-threatening cardiac troubles.

The fat deposition also hampers the elasticity of the arteries. That means obesity can cause havoc in our body by altering the blood pressure to an abnormal range. And this is just the tip of the iceberg. Obesity is known to create an endless list of problems.

In extreme cases, this disorder gives birth to acute diseases like diabetes and cancer. The weight gain due to obesity puts a lot of pressure on the bones of the body, especially of the legs. This, in turn, makes our bones weak and disturbs their smooth movement. A person suffering from obesity also has higher chances of developing infertility issues and sleep troubles.

Many obese people are seen to be struggling with breathing problems too. In the chronic form, the condition can grow into asthma. The psychological effects of obesity are another serious topic. You can say that obesity and depression form a loop. The more a person is obese, the worse is his/ her depression stage.

How to Control and Treat Obesity:

The simplest and most effective way, to begin with, is changing our diet. There are two factors to consider in the diet plan. First is what and what not to eat. Second is how much to eat.

If you really want to get rid of obesity, include more and more green vegetables in your diet. Spinach, beans, kale, broccoli, cauliflower, asparagus, etc., have enough vitamins and minerals and quite low calories. Other healthier options are mushrooms, pumpkin, beetroots, and sweet potatoes, etc.

Opt for fresh fruits, especially citrus fruits, and berries. Oranges, grapes, pomegranate, pineapple, cherries, strawberries, lime, and cranberries are good for the body. They have low sugar content and are also helpful in strengthening our immune system. Eating the whole fruits is a more preferable way in comparison to gulping the fruit juices. Fruits, when eaten whole, have more fibers and less sugar.

Consuming a big bowl of salad is also great for dealing with the obesity problem. A salad that includes fibrous foods such as carrots, radish, lettuce, tomatoes, works better at satiating the hunger pangs without the risk of weight gain.

A high protein diet of eggs, fish, lean meats, etc., is an excellent choice to get rid of obesity. Take enough of omega fatty acids. Remember to drink plenty of water. Keeping yourself hydrated is a smart way to avoid overeating. Water also helps in removing the toxins and excess fat from the body.

As much as possible, avoid fats, sugars, refined flours, and oily foods to keep the weight in control. Control your portion size. Replace the three heavy meals with small and frequent meals during the day. Snacking on sugarless smoothies, dry fruits, etc., is much recommended.

Regular exercise plays an indispensable role in tackling the obesity problem. Whenever possible, walk to the market, take stairs instead of a lift. Physical activity can be in any other form. It could be a favorite hobby like swimming, cycling, lawn tennis, or light jogging.

Meditation and yoga are quite powerful practices to drive away the stress, depression and thus, obesity. But in more serious cases, meeting a physician is the most appropriate strategy. Sometimes, the right medicines and surgical procedures are necessary to control the health condition.

Obesity is spreading like an epidemic, haunting both the adults and the kids. Although genetic factors and other physical ailments play a role, the problem is mostly caused by a reckless lifestyle.

By changing our way of living, we can surely take control of our health. In other words, it would be possible to eliminate the condition of obesity from our lives completely by leading a healthy lifestyle.

Obesity Epidemic: Causes and Solutions

Since the 1980s, the prevalence of obesity in the United States has increased dramatically. Data collected by the Centers for Disease Control and Prevention show rising obesity across the nation, state-by-state . 1

The figure shows three maps of the U.S. with states color-coded based on the percent of the their population estimated to be obese. In 1990, all of the states are a blue color, indicating 10-14 percent of their populations were obese. In 2000, many states are a darker blue color, indicating 15-19 percent obesity, and about half of a beige color, indicating 20 to 24 percent obesity. In 2010, there are still some beige states but no blue ones, and many are orange or red, indicating 25 to 30+ percent obesity.

Figure 7.17. Each year since 1990, the CDC has published maps of the United States in which states are color-coded based on the percentage of their population estimated to be obese. The maps show a clear increase in the prevalence of obesity between 1990 and 2010.

The methods used by the CDC to collect the data changed in 2011, so we can’t make direct comparisons between the periods before and after that change, but the trend has continued. Every year, more and more people in the U.S. are obese.

A map of the U.S. showing obesity prevalence color-coded by state. States are about evenly split between green (20-25% obesity), yellow (25-30% obesity), or red (30-35% obesity).

Figure 7.18. The prevalence of obesity among U.S. adults has continued to rise between 2011 and 2018.

These trends are unmistakable, and they’re not just occurring in adults. Childhood obesity has seen similar increases over the last few decades—perhaps an even greater concern as the metabolic and health effects of carrying too much weight can be compounded over a person’s entire lifetime.

A line graph shows the prevalence of obesity trending upwards between the years 1999-2000 and 2015-2016 in both children and adults. In this time span, the prevalence of obesity in children increased from 13.9 to 18.5 percent. In adults, it increased from 30.5 to 39.6 percent.

Figure 7.19. Between 1999 and 2016, the prevalence of obesity in both children and adults has risen steadily.

While obesity is a problem across the United States, it affects some groups of people more than others. Based on 2015-2016 data, obesity rates are higher among Hispanic (47 percent) and Black adults (47 percent) compared with white adults (38 percent). Non-Hispanic Asians have the lowest obesity rate (13 percent). And overall, people who are college-educated and have a higher income are less likely to be obese. 2 These health disparities point to the importance of looking at social context when examining causes and solutions. Not everyone has the same opportunity for good health, or an equal ability to make changes to their circumstances, because of factors like poverty and longstanding inequities in how resources are invested in communities. These factors are called “ social determinants of health . ” 3

The obesity epidemic is also not unique to the United States. Obesity is rising around the globe, and in 2015, it was estimated to affect 2 billion people worldwide, making it one of the largest factors affecting poor health in most countries . 4 Globally, among children aged 5 to 19 years old, the rate of overweight increased from 10.3 percent in 2000 to 18.4 percent in 2018. Previously, overweight and obesity mainly affected high-income countries, but some of the most dramatic increases in childhood overweight over the last decade have been in low income countries, such as those in Africa and South Asia, corresponding to a greater availability of inexpensive, processed foods. 5

Despite the gravity of the problem, no country has yet been able to implement policies that have reversed the trend and brought about a decrease in obesity. This represents “one of the biggest population health failures of our time,” wrote an international group of researchers in the journal  The Lancet  in 2019 . 6 The World Health Organization has set a target of stopping the rise of obesity by 2025. Doing so requires understanding what is causing the obesity epidemic; it is only when these causes are addressed that change can start to occur.

Causes of the Obesity Epidemic

If obesity was an infectious disease sweeping the globe, affecting billions of people’s health, longevity, and productivity, we surely would have addressed it by now. Researchers and pharmaceutical companies would have worked furiously to develop vaccines and medicines to prevent and cure this disease. But the causes of obesity are much more complex than a single bacteria or virus, and solving this problem means recognizing and addressing a multitude of factors that lead to weight gain in a population.

At its core, rising obesity is caused by a chronic shift towards positive energy balance—consuming more energy or calories than one expends each day, leading to an often gradual but persistent increase in body weight. People often assume that this is an individual problem, that those who weigh more simply need to change their behavior to eat less and exercise more, and if this doesn’t work, it must be because of a personal failing, such as a lack of self-control or motivation. While behavior patterns such as diet and exercise can certainly impact a person’s risk of developing obesity (as we’ll cover later in this chapter), the environments where we live also have a big impact on our behavior and can make it much harder to maintain energy balance.

Environment

Many of us live in what researchers and public health experts call “ obesogenic environments. ” That is, the ways in which our neighborhoods are built and our lives are structured influence our physical activity and food intake to encourage weight gain . 7 Human physiology and metabolism evolved in a world where obtaining enough food for survival required significant energy investment in hunting or gathering—very different from today’s world where more people earn their living in sedentary occupations. From household chores, to workplace productivity, to daily transportation, getting things done requires fewer calories than it did in past generations.

The image shows three photos. Left to right: a group of well-dressed Black women sit at a work conference table, with laptops in front of them; 4 vending machines sell snacks and soft drinks; and cars jamming a freeway.

Figure 7.20. Some elements of our environment that may make it easier to gain weight include sedentary jobs, easy access to inexpensive calories, and cities built more for car travel than for physical activity.

Our jobs have become more and more sedentary, with fewer opportunities for non-exercise thermogenesis (NEAT) throughout the day. There’s less time in the school day for recess and physical activity, and fears about neighborhood safety limit kids’ ability to get out and play after the school day is over. Our towns and cities are built more for cars than for walking or biking. We can’t turn back the clock on human progress, and finding a way to stay healthy in obesogenic environments is a significant challenge.

Our environments  can also impact our food choices. We’re surrounded by vending machines, fast food restaurants, coffeeshops, and convenience stores that offer quick and inexpensive access to calories. These foods are also heavily advertised, and especially when people are stretched thin by working long hours or multiple jobs, they can be a welcome convenience. However, they tend to be calorie-dense (and less nutrient-dense) and more heavily processed, with amounts of sugar, fat, and salt optimized to make us want to eat more, compared with home-cooked food. In addition, portion sizes at restaurants, especially fast food chains, have increased over the decades, and people are eating at restaurants more and cooking at home less.

Poverty and Food Insecurity

Living in poverty usually means living in a more obesogenic environment. Consider the fact that some of the poorest neighborhoods in the United States—with some of the highest rates of obesity—are often not safe or pleasant places to walk, play, or exercise. They may have busy traffic and polluted air, and they may lack sidewalks, green spaces, and playgrounds. A person living in this type of neighborhood will find it much more challenging to get adequate physical activity compared with someone living in a neighborhood where it’s safe to walk to school or work, play at a park, ride a bike, or go for a run.

In addition, poor neighborhoods often lack a grocery store where people can purchase fresh fruits and vegetables and basic ingredients necessary for cooking at home. Such areas are called “ food deserts ”—where healthy foods simply aren’t available or easily accessible.

Another concept useful in discussions of obesity risk is “food insecurity.”  Food security means “access by all people at all times to enough food for an active, healthy life.” 8  Food insecurity   means an inability to consistently obtain adequate food. It may seem counter-intuitive, but in the United States, food insecurity is linked to obesity. That is, people who have difficulty obtaining enough food are more likely to become obese and to suffer from diabetes and hypertension. This is likely related to the fact that inexpensive foods tend to be high in calories but low in nutrients, and when these foods form the foundation of a person’s diet, they can cause both obesity and nutrient deficiencies. It’s estimated that 12 percent of U.S. households are food insecure, and food insecurity is higher among Black (22 percent) and Latino (18 percent) households. 3

What about genetics? While it’s true that our genes can influence our susceptibility to becoming obese, researchers say they can’t be a cause of the obesity epidemic. Genes take many generations to evolve, and the obesity epidemic has occurred over just the last 40 to 50 years—only a few generations. When our grandparents were children, they were much less likely to become obese than our own children. That’s not because their genes were different, but rather because they grew up in a different environment. However, it is true that a person’s genes can influence their susceptibility to becoming obese in this obesogenic environment, and obesity is more prevalent in some families. A person’s genetic make-up can make it more difficult to maintain energy balance in an obesogenic environment, because certain genes may make you feel more hungry or slow your energy expenditure. 2

Solutions to the Obesity Epidemic

Given the multiple causes of obesity, solving this problem will also require many solutions at different levels. Because obesity affects people over the lifespan and is difficult to reverse, the focus of many of these efforts is prevention , starting as early as the first years of life. We’ll discuss individual weight management strategies later in this chapter. Here, we’ll review some strategies happening in schools, communities, and at the state and federal levels.

Support Healthy Dietary Patterns

Interventions that support healthy dietary patterns, especially among people more vulnerable because of food insecurity or poverty, may reduce obesity. In some cases, studies have shown that they have an impact, and in other cases, it’s too soon to know. Here are some examples:

  • Implement and support better nutrition standards for childcare, schools, hospitals, and worksites. 9
  • Limit marketing of processed foods, especially ads targeted towards children.
  • Provide incentives for supermarkets or farmers markets to establish businesses in underserved areas. 9

On the right, a closeup of a farmers' market stand, showing enticing fresh vegetables like carrots, cucumbers, tomatoes, and beets.

  • Place nutrition and calorie content on restaurant and fast food menus  to raise awareness of food choices. 9 Beginning in 2018, as part of the Affordable Care Act, chain restaurants with more than 20 locations were required to add calorie information to their menus, and some had already done so voluntarily. There isn’t yet enough research to say whether having this information improves customers’ choices; some studies show an effect and others don’t. 10 Many factors influence people’s decisions, and the type of restaurant, customer needs, and menu presentation all likely matter. For example, some studies show that health-conscious consumers choose lower calorie menu items when presented with nutrition information, but people with food insecurity may understandably choose higher calorie items to get more “bang for their buck”. 11 Research has also shown that adding interpretative images—like a stoplight image labeling menu choices as green or red as shorthand for high or low nutrient density—can help. And a 2018 study found that when calorie counts are on the left side of English-language menus, people order lower-calorie menu items. Putting calorie counts on the right side of the menu (as is more common) doesn’t have this effect, likely because the English language is read from left to right. 12 Some studies have also found that restaurants that implement menu labeling offer lower-calorie and more nutrient-dense options, indicating that menu labeling may push restaurants to look more closely at the food they serve. 10,13

  • Increase access to food assistance programs and align them with nutrition recommendations. For example, in 2009, the U.S. Department of Agriculture revised the food packages for the Women, Infants, and Children (WIC) program to better align with the Dietary Guidelines for Americans. The new packages emphasized more  fruits, vegetables, whole grains, and low-fat dairy and decreased the availability of juice. After this change, there was a decrease in the obesity rate of children in the WIC program. Similar progress may be made by increasing access to the Supplemental Nutrition Assistance Program (SNAP) in order to reduce food insecurity. Many farmers’ markets now accept SNAP benefits for the purchase of fresh fruit and vegetables. 3
  • Tax sugary drinks, such as soda and sports drinks, which contribute significant empty calories to the U.S. diet and are associated with childhood obesity. Local taxes on soda and other sugary drinks are often controversial, and soda companies lobby to prevent them from passing. However, early research in U.S. cities with soda taxes show that they do work to decrease soda consumption. 3 In the U.S., soda has only been taxed at the local level, and the tax has been paid by consumers. The United Kingdom has taken a different approach: They started taxing soft drink manufacturers for the sugar content of the products they sell. Between 2015 and 2018, the average sugar content of soda sold in the U.K. dropped by 29 percent. 14

Support Greater Physical Activity

Increasing physical activity increases the energy expended during the day. This can help maintain energy balance, thus preventing weight gain. It may also help to shift a person into negative energy balance and facilitate weight loss if needed. But simply adding an exercise session—a run or a trip to the gym, say—often doesn’t shift energy balance (though it’s certainly good for health). Why? Exercise can increase hunger, and there’s only so many calories a person can burn in 30 or 60 minutes. That’s why it’s also important to look for opportunities for non-exercise activity thermogenesis (NEAT); that is, find ways to increase movement throughout the day.  

  • P rioritize physical education and recess time in schools. In addition to helping kids stay healthy, movement also helps them learn.
  • Make neighborhoods safer and more accessible for walking, cycling, and playing.
  • When safe, encourage kids to walk or bike to school.
  • Build family and community activities around physical activity, such as trips to the park, walks together, and community walking and exercise groups.
  • Facilitate more movement in the workday by encouraging walking meetings, movement breaks, and treadmill desks.
  • Find ways to move that are enjoyable to you and fit your life. Yard work, walking your dog, playing tag with your kids, and going out dancing all count!

Band 8 Sample | Causes of Obesity

Band 8 Sample | Causes of Obesity

Essay topic

In some countries the average weight of people is increasing and their levels of health and fitness are decreasing. What do you think are the causes of these problems and what measures could be taken to solve them?

Band 8 essay sample

It is a fact that in some countries, the average weight of the citizens is shooting up while their fitness and health conditions are worsening. In my view this is mainly because of the food habits and modern lifestyle they follow. In this essay, I will examine these two factors and then propose a viable solution.

One of the foremost reasons for obesity is the consumption of unhealthy foods. Many people started to follow western food habits and eventually ended up eating high fat content foods like pizza and burger. Regular consumption of these fat rich foods will increase a person’s weight in a short span of time.

In addition to that, now-a-days, more and more people are living a sedentary lifestyle. They do not dedicate any time to do any kind of physical activity. As a result, they lose their resistance power. If this lifestyle continues then people will fall ill more frequently and lose their health permanently.

It is necessary that the government takes steps to open many sports complexes and fitness studios near residential communities. Most of the people who do not want to travel far to go to a sports center will be ready to use one if it is available nearby. In a study conducted by a popular newspaper 90% of the respondents said that they are willing to use the gym or any physical activity centers if they are within 3 kilometer radius.

To conclude, encouraging people to do more physical activities will not only improve their fitness and overall health but also help people to shed their weight.
