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.

Causes of obesity

Do you see any obese or overweight people around you?

You likely do.

This is because fast-food chains are becoming more and more common, people are less active, and fruits and vegetables are more expensive than processed foods, thus making them less available to the majority of society. These are the primary causes of obesity.

Obesity is a disease that affects all age groups, including children and elderly people.

Now that you are familiar with the topic of obesity, writing an essay won’t be that difficult for you.

How to Write an Obesity Essay

Prevention, prevention, prevention.

Losing weight is hard to do.

In the U.S., only one in six adults who have dropped excess pounds actually keep off at least 10 percent of their original body weight. The reason: a mismatch between biology and environment. Our bodies are evolutionarily programmed to put on fat to ride out famine and preserve the excess by slowing metabolism and, more important, provoking hunger. People who have slimmed down and then regain their weight don’t lack willpower—their bodies are fighting them every inch of the way.

This inborn predisposition to hold on to added weight reverberates down the life course. Few children are born obese, but once they become heavy, they are usually destined to be heavy adolescents and heavy adults. According to a 2016 study in the New England Journal of Medicine , approximately 90 percent of children with severe obesity will become obese adults with a BMI of 35 or higher. Heavy young adults are generally heavy in middle and old age. Obesity also jumps across generations; having a mother who is obese is one of the strongest predictors of obesity in children.

All of which means that preventing child obesity is key to stopping the epidemic. By the time weight piles up in adulthood, it is usually too late. Luckily, preventing obesity in children is easier than in adults, partly because the excess calories they absorb are minimal and can be adjusted by small changes in diet—substituting water, for example, for sugary fruit juices or soda.

Still, the bulk of the obesity problem—literally—is in adults. According to Frank Hu, chair of the Harvard Chan Department of Nutrition, “Most people gain weight during young and middle adulthood. The weight-gain trajectory is less than 1 pound per year, but it creeps up steadily from age 18 to age 55. During this time, people gain fat mass, not muscle mass. When they reach age 55 or so, they begin to lose their existing muscle mass and gain even more fat mass. That’s when all the metabolic problems appear: insulin resistance, high cholesterol, high blood pressure.”

Adds Walter Willett, Frederick John Stare Professor of Epidemiology and Nutrition at Harvard Chan, “The first 5 pounds of weight gain at age 25—that’s the time to be taking action. Because someone is on a trajectory to end up being 30 pounds overweight by the time they’re age 50.”

The most realistic near-term public health goal, therefore, is not to reverse but rather to slow down the trend—and even this will require strong commitment from government at many levels. In May 2017, the Trump administration rolled back recently-enacted standards for school meals, delaying a rule to lower sodium and allowing waivers for regulations requiring cafeterias to serve foods rich in whole grains. If recent expansions in food entitlements and school meals are undermined, “It would be a ‘disaster,’ to use the president’s word,” says Marlene Schwartz, director of the Rudd Center for Obesity & Food Policy at the University of Connecticut. “The federal food programs are incredibly important, not just because of the food and money they provide families, but because supporting better nutrition in child care, schools, and the WIC [Women, Infants, and Children] program has created new social norms. We absolutely cannot undo the progress that we’ve made in helping this generation transition to a healthier diet.”

Get the science right.

It is impossible to prescribe solutions to obesity without reminding ourselves that nutrition scientists botched things decades ago and probably sent the epidemic into overdrive. Beginning in the 1970s, the U.S. government and major professional groups recommended for the first time that people eat a low-fat/high-carbohydrate diet. The advice was codified in 1977 with the first edition of The Dietary Goals for the United States , which aimed to cut diet-related conditions such as heart disease and diabetes. What ensued amounted to arguably the biggest public health experiment in U.S. history, and it backfired.

At the time, saturated fat and dietary cholesterol were believed to be the main factors responsible for cardiovascular disease—an oversimplified theory that ignored the fact that not all fats are created equal. Soon, the public health blitz against saturated fat became a war on all fat. In the American diet, fat calories plummeted and carb calories shot up.

“We can’t blame industry for this. It was a bandwagon effect in the scientific community, despite the lack of evidence—even with evidence to the contrary,” says Willett. “Farmers have known for thousands of years that if you put animals in a pen, don’t let them run around, and load them up with grains, they get fat. That’s basically what has been happening to people: We created the great American feedlot. And we added in sugar, coloring, and seductive promotion for low-fat junk food.”

Scientists now know that whole fruits and vegetables (other than potatoes), whole grains, high-quality proteins (such as from fish, chicken, beans, and nuts), and healthy plant oils (such as olive, peanut, or canola oil) are the foundations of a healthy diet.

But there is also a lot scientists don’t yet know. One unanswered question is why some people with obesity are spared the medical complications of excess weight. Another concerns the major mechanisms by which obesity ushers in disease. Although surplus body weight can itself directly cause problems—such as arthritis due to added load on joints, or breast cancer caused by hormones secreted by fat cells—in general, obesity triggers myriad biological processes. Many of the resulting conditions—such as atherosclerosis, diabetes, and even Alzheimer’s disease—are mediated by inflammation, in which the body’s immune response becomes damagingly self-perpetuating. In this sense, today’s food system is as inflammagenic as it is obesigenic.

Scientists also need to ferret out the nuanced effects of particular foods. For example, do fermented products—such as yogurt, tempeh, or sauerkraut—have beneficial properties? Some studies have found that yogurt protects against weight gain and diabetes, and suggest that healthy live bacteria (known as probiotics) may play a role. Other reports point to fruits being more protective than vegetables in weight control and diabetes prevention, although the types of fruits and vegetables make a difference.

A 2017 article in the American Journal of Clinical Nutrition showed that substituting whole grains for refined grains led to a loss of nearly 100 calories a day—by speeding up metabolism, cutting the number of calories that the body hangs on to, and, more surprisingly, by changing the digestibility of other foods on the plate. That extra energy lost daily—by substituting, say, brown rice for white rice or barley for pita bread—was equivalent to a brisk 30-minute walk. One hundred calories a day, sustained over years, and multiplied by the population is one mathematical equivalent of the obesity epidemic.

A companion study found that adults who ate a whole-grain-rich diet developed healthier gut bacteria and improved immune responses. That particular foods alter the gut microbiome—the dense and vital community of bacteria and other microorganisms that work symbiotically with the body’s own digestive system—is another critical insight. The microbiome helps determine weight by controlling how our bodies extract calories and store fat in the liver, and the microbiomes of obese individuals are startlingly efficient at harvesting calories from food. [To learn more about Harvard Chan research on the gut microbiome, read “ Bugs in the System .”] The hormonal effects of sleep deprivation and stress—two epidemics concurrent and intertwined with the obesity trend—are other promising avenues of research.

And then there are the mystery factors. One recent hypothesis is that an agent known as adenovirus 36 partly accounts for our collective heft. A 2010 article in The Royal Society described a study in which researchers examined samples of more than 20,000 animals from eight species living with or around humans in industrialized nations, a menagerie that included macaques, chimpanzees, vervets, marmosets, lab mice and rats, feral rats, and domestic dogs and cats. Like their Homo sapiens counterparts, all of the study populations had gained weight over the past several decades—wild, domestic, and lab animals alike. The chance that this is a coincidence is, according to the scientists’ estimate, 1 in 10 million. The stumped authors surmise that viruses, gene expression changes, or “as-of-yet unidentified and/or poorly understood factors” are to blame.

Master the art of persuasion.

A 2015 paper in the American Journal of Public Health revealed the philosophical chasm that hampers America’s progress on obesity prevention. It found that 72 to 98 percent of obesity-related media reports emphasize personal responsibility for weight, compared with 40 percent of scientific papers.

A recent study by Drexel University researchers also quantified the political polarization around public health measures. From 1998 through 2013, Democrats voted in line with recommendations from the American Public Health Association 88.3 percent of the time, on average, while Republicans voted for the proposals just 21.3 percent of the time.

Clearly, we can’t count on bipartisan goodwill to stem the obesity crisis. But we can ask what kinds of messages appeal to politically divergent audiences. A stealth strategy may be to avoid even uttering the word “obesity.” On January 1 of this year, Philadelphia’s 1.5-cents-per-ounce excise tax on sugar-sweetened and diet beverages took effect. When Philadelphia Mayor Jim Kenney lobbied voters to approve the tax, his bid centered not on improving health—the unsuccessful pitch of his predecessor—but on raising $91 million annually for prekindergarten programs.

“That’s something lots of people care about and can get behind—it’s a feel-good policy, and it makes sense,” says psychologist Christina Roberto, assistant professor of medical ethics and health policy at the University of Pennsylvania, and a former assistant professor of social and behavioral sciences and nutrition at Harvard Chan. The provision for taxing diet beverages was also shrewd, she adds, because it spread the tax’s pain; since wealthier people are more likely than less-affluent individuals to buy diet drinks, the tax could not be slapped with the label “regressive.”

But Roberto sees a larger lesson in the Philadelphia story. Public health messaging that appeals to values that transcend the individual is less fraught, less stigmatizing, and perhaps more effective. As she puts it, “It’s very different to hear the message, ‘Eat less red meat, help the planet’ versus ‘Eat less red meat, help yourself avoid saturated fat and cardiovascular disease.’”

Supermarket makeovers

Supermarket aisles are other places where public health can shuffle a deck stacked against healthy consumer choices.

With slim profit margins and 50,000-plus products on their shelves, grocery stores depend heavily on food manufacturers’ promotional incentives to make their bottom lines. “Manufacturers pay slotting fees to get their products on the shelf, and they pay promotion allowances: We’ll give you this much off a carton of Coke if you put it on sale for a certain price or if you put it on an end-of-aisle display,” says José Alvarez, former president and chief executive officer of Stop & Shop/Giant-Landover, now senior lecturer of business administration at Harvard Business School. Such promotional payments, Alvarez adds, often exceed retailers’ net profits.

Healthy new products—like flash-frozen dinners prepared with heaps of vegetables and whole grains, and relatively little salt—can’t compete for prized shelf space against boxed mac and cheese or cloying breakfast cereals. One solution, says Alvarez, is for established consumer packaged goods companies to buy out what he calls the “hippie in the basement” firms that have whipped up more nutritious items. The behemoths could apply their production, marketing, and distribution prowess to the new offerings—and indeed, this has started to happen over the last five years.

Another approach is to make nutritious foods more convenient to eat. “We have all of these cooking shows and upscale food magazines, but most people don’t have the time or inclination—or the skills, quite frankly—to cook,” says Alvarez. “Instead, we should focus on creating high-quality, healthy, affordable prepared foods.”

An additional model is suggested by Jeff Dunn, a 20-year veteran of the soft drink industry and former president of Coca-Cola North America, who went on to become an advocate for fresh, healthy food. Dunn served as president and chief executive officer of Bolthouse Farms from 2008 to 2015, where he dramatically increased sales of baby carrots by using marketing techniques common in the junk food business. “We operated on the principles of the three 3 A’s: accessibility, availability, and affordability,” says Dunn. “That, by the way, is Coke’s more-than-70-year-old formula for success.”

Show them the money.

Obesity kills budgets. According to the Campaign to End Obesity, a collaboration of leaders from industry, academia, public health, and policymakers, annual U.S. health costs related to obesity approach $200 billion. In 2010, the nonpartisan Congressional Budget Office reported that nearly 20 percent of the rise in health care spending from 1987 to 2007 was linked to obesity. And the U.S. Centers for Disease Control and Prevention (CDC) found that full-time workers in the U.S. who are overweight or obese and have other chronic health conditions miss an estimated 450 million more days of work each year than do healthy employees—upward of $153 billion in lost productivity annually.

But making the money case for obesity prevention isn’t straightforward. For interventions targeting children and youth, only a small fraction of savings is captured in the first decade, since most serious health complications don’t emerge for many years. Long-term obesity prevention, in other words, doesn’t fit into political timetables for elected officials.

Yet lawmakers are keen to know how “best for the money” obesity-prevention programs can help them in the short run. Over the past two years, Harvard Chan’s Steve Gortmaker and his colleagues have been working with state health departments in Alaska, Mississippi, New Hampshire, Oklahoma, Washington, and West Virginia and with the city of Philadelphia and other locales, building cost-effectiveness models using local data for a wide variety of interventions—from improved early child care to healthy school environments to communitywide campaigns. “We collaborate with health departments and community stakeholders, provide them with the evidence base, help assess how much different options cost, model the results over a decade, and they pick what they want to work on. One constant that we’ve seen—and these are very different political environments—is a strong interest in cost-effectiveness,” he says.

In a 2015 study in Health Affairs , Gortmaker and colleagues outlined three interventions that would more than pay for themselves: an excise tax on sugar-sweetened beverages implemented at the state level; elimination of the tax subsidy for advertising unhealthy food to children; and strong nutrition standards for food and drinks sold in schools outside of school meals. Implemented nationally, these interventions would prevent 576,000, 129,100, and 345,000 cases of childhood obesity, respectively, by 2025. The projected net savings to society in obesity-related health care costs for each dollar invested: $31, $33, and $4.60, respectively.

Gortmaker is one of the leaders of a collaborative modeling effort known as CHOICES—for Childhood Obesity Intervention Cost-Effectiveness Study—an acronym that seems a pointed rebuttal to the reflexive conservative argument that government regulation tramples individual choice. Having grown up not far from Des Plaines, Illinois, site of the first McDonald’s franchise in the country, he emphasizes to policymakers that at this late date, America cannot treat its way out of obesity, given current medical know-how. Only a thoroughgoing investment in prevention will turn the tide. “Clinical interventions produce too small an effect, with too small a population, and at high cost,” Gortmaker says. “The good news is that there are many cost-effective options to choose from.”

While Gortmaker underscores the importance of improving both food choices and options for physical activity, he has shown that upgrading the food environment offers much more benefit for the buck. This is in line with the gathering scientific consensus that what we eat plays a greater role in obesity than does sedentary lifestyle (although exercise protects against many of the metabolic consequences of excess weight). “The easiest way to explain it,” Gortmaker says, “is to talk about a sugary beverage—140 calories. You could quickly change a kid’s risk of excess energy balance by 140 calories a day just by switching from a sugary drink a day to water or sparkling water. But for a 10-year-old boy to burn an extra 140 calories, he’d have to replace an hour-and-a-half of sitting with an hour-and-a-half of walking.”

Small tweaks in adults’ diets can likewise make a big difference in short order. “With adults, health care costs rise rapidly with excess weight gain,” Gortmaker says. “If you can slow the onset of obesity, you slow the onset of diabetes, and potentially not only save health care costs but also boost people’s productivity in the workforce.”

One of Gortmaker’s most intriguing calculations spins off of the food industry’s estimated $633 million spent on television marketing aimed at kids. Currently, federal tax treatment of advertising as an ordinary business expense means that the government, in effect, subsidizes hawking of junk food to children. Gortmaker modeled a national intervention that would eliminate this subsidy of TV ads for nutritionally empty foods and beverages aimed at 2- to 19-year-olds. Drawing on well-delineated relationships between exposure to these advertisements and subsequent weight gain, he found that the intervention would save $260 million in downstream health care costs. Although the effect would probably be small at the individual level, it would be significant at the population level.

Level the playing field through taxes and regulation.

When public health took on cigarette smoking, starting in the 1960s, it did so with robust policies banning television ads and other marketing, raising taxes to increase prices, making public places smoke-free, and offering people treatment such as the nicotine patch. In 1965, the smoking rate for U.S. adults was 42.2 percent; today, it is 16.8 percent.

Similarly, America reduced the rate of deaths caused by motor vehicle accidents—a 90 percent decrease over the 20th century, according to the CDC—with mandatory seat belt laws, safer car designs, stop signs, speed limits, rumble strips, and the stigmatization of drunk driving.

Change the product. Change the environment. Change the culture. That is also the policy recipe for stopping obesity.

Laws that make healthy behaviors easier are often followed by positive changes in those behaviors. And people who are trying to adopt healthy behaviors tend to support policies that make their personal aspirations achievable, which in turn nudges lawmakers to back the proposals.

One debate today revolves around whether recipients of federal Supplemental Nutrition Assistance Program (SNAP) benefits (formerly known as food stamps) should be restricted from buying sodas or junk food. The largest component of the USDA budget, SNAP feeds one in seven Americans. A USDA report, issued last November, found that the number-one purchase by SNAP households was sweetened beverages, a category that included soft drinks, fruit juices, energy drinks, and sweetened teas, accounting for nearly 10 percent of SNAP money spent on food. Is the USDA therefore underwriting the soda industry and planting the seeds for chronic disease that the government will pay to treat years down the line?

Eric Rimm, a professor in the Departments of Epidemiology and Nutrition at the Harvard Chan School, frames the issue differently. In a 2017 study in the American Journal of Preventive Medicine , he and his colleagues asked SNAP participants whether they would prefer the standard benefits package or a “SNAP-plus” that prohibited the purchase of sugary beverages but offered 50 percent more money for buying fruits and vegetables. Sixty-eight percent of the participants chose the healthy SNAP-plus option.

“A lot of work around SNAP policy is done by academics and politicians, without reaching out to the beneficiaries,” says Rimm. “We haven’t asked participants, ‘What’s your say in this? How can we make this program better for you?’” To be sure, SNAP is riddled with nutritional contradictions. Under current rules, for example, participants can use benefits to buy a 12-pack of Pepsi or a Snickers bar or a giant bag of Lay’s potato chips but not real food that happens to be heated, such as a package of rotisserie chicken. “This is the most vulnerable population in the country,” says Rimm. “We’re not listening well enough to our constituency.”

Other innovative fiscal levers to alter behavior could also drive down obesity. In 2014, a trio of strong voices on food industry practices—Dariush Mozaffarian, DrPH ’06, dean of Tufts University’s Friedman School of Nutrition Science and Policy and former associate professor of epidemiology at the Harvard Chan School; Kenneth Rogoff, professor of economics at Harvard; and David Ludwig, professor in the Department of Nutrition at Harvard Chan and a physician at Boston Children’s Hospital—broached the idea of a “meaningful” tax on nearly all packaged retail foods and many chain restaurants, with the proceeds used to pay for minimally processed foods and healthier meals for school kids. In essence, the tax externalizes the social costs of harmful individual behavior.

“We made a straightforward proposal to tax all processed foods and then use the income to subsidize whole foods in a short-term, revenue-neutral way,” explains Ludwig. “The power of this idea is that, since there is so much processed food consumption, even a modest tax—in the 10 to 15 percent range—is not going to greatly inflate the cost of these foods. Their price would increase moderately, but the proceeds would not disappear into government coffers. Instead, the revenue would make healthy foods affordable for virtually the entire population, and the benefits would be immediately evident. Yes, people will pay moderately more for their Coke or for their cinnamon bear claw but a lot less for nourishing, whole foods.”

Another suggestion comes from Sandro Galea, dean of the Boston University School of Public Health, and Abdulrahman M. El-Sayed, a public health physician and epidemiologist. In a 2015 issue of the American Journal of Public Health , they called for “calorie offsets,” similar to the carbon offsets used to mitigate environmental harm caused by the gas and oil industries. A “calorie offset” scheme could hand the food and beverage industries a chance at redemption by inviting them to invest in such undertakings as city farms, cooking classes for parents, healthy school cafeterias, and urban green spaces.

These ambitious proposals face almost impossibly high hurdles. Political battle lines typically pit public health against corporations, with Big Food casting doubt on solid nutrition science, deeming government regulation a threat to free choice, and making self-policing pledges that it has never kept. On the website for the Americans for Food and Beverage Choice, a group spearheaded by the American Beverage Association, is the admonition: “[W]hether it’s at a restaurant or in a grocery store, it’s never the government’s job to decide what you choose to eat and drink.”

Yet surprisingly, many public health professionals are convinced that the only way to stop obesity is to make common cause with the food industry. “This isn’t like tobacco, where it’s a fight to the death. We need the food industry to make healthier food and to make a profit,” says Mozaffarian. “The food industry is much more diverse and heterogeneous than tobacco or even cars. As long as we can help them—through carrots and sticks, tax incentives and disincentives—to move towards healthier products, then they are part of the solution. But we have to be vigilant, because they use a lot of the same tactics that tobacco did.”

Sow what we want to reap.

Americans overeat what our farmers overproduce.

“The U.S. food system is egregiously terrible for human and planetary health,” says Walter Willett. It’s so terrible, Willett made a pie chart of American grain production consumed domestically. It shows that most of the country’s agricultural land goes to the two giant commodity crops: corn and soy. Most of those crops, in turn, go to animal fodder and ethanol, and are also heavily used in processed snack foods. Today, only about 10 percent of grain grown in the U.S. for domestic use is eaten directly by human beings. According to a 2013 report from the Union of Concerned Scientists, only 2 percent of U.S. farmland is used to grow fruits and vegetables, while 59 percent is devoted to commodity crops.

Historically, those skewed proportions made sense. Federal food policies, drafted with the goal of alleviating hunger, preferentially subsidize corn and soy production. And whereas corn or soybeans could be shipped for days on a train, fruits and vegetables had to be grown closer to cities by truck farmers so the produce wouldn’t spoil. But those long-ago constraints don’t explain today’s upside-down agricultural priorities.

In a now-classic 2016 Politico article titled “The farm bill drove me insane,” Marion Nestle illustrated the irrational gap between what the government recommends we eat and what it subsidizes: “If you were to create a MyPlate meal that matched where the government historically aimed its subsidies, you’d get a lecture from your doctor. More than three-quarters of your plate would be taken up by a massive corn fritter (80 percent of benefits go to corn, grains and soy oil). You’d have a Dixie cup of milk (dairy gets 3 percent), a hamburger the size of a half dollar (livestock: 2 percent), two peas (fruits and vegetables: 0.45 percent) and an after-dinner cigarette (tobacco: 2 percent). Oh, and a really big linen napkin (cotton: 13 percent) to dab your lips.”

In this sense, the USDA marginalizes human health. Many of the foods that nutritionists agree are best for us—notably, fruits, vegetables, and tree nuts—fall under the bureaucratic rubric “specialty crops,” a category that also includes “dried fruits, horticulture, and nursery crops (including floriculture).” Farm bills, which get passed every five years or so, fortify the status quo. The 2014 Farm Bill, for example, provided $73 million for the Specialty Crop Block Grant Program in 2017, out of a total of about $25 billion for the USDA’s discretionary budget. (The next Farm Bill, now under debate, will be coming out in 2018.)

By contrast, a truly anti-obesigenic agricultural system would stimulate USDA support for crop diversity—through technical assistance, research, agricultural training programs, and financial aid for farmers who are newly planting or transitioning their land into produce. It would also enable farmers, most of whom survive on razor-thin profit margins, to make a decent living.

In the early 1970s, Finland’s death rate from coronary heart disease was the highest in the world, and in the eastern region of North Karelia—a pristine, sparsely populated frontier landscape of forest and lakes—the rate was 40 percent worse than the national average. Every family saw physically active men, loggers and farmers who were strong and lean, dying in their prime.

Thus was born the North Karelia Project, which became a model worldwide for saving lives by transforming lifestyles. The project was launched in 1972 and officially ended 25 years later. While its initial goal was to reduce smoking and saturated fat in the diet, it later resolved to increase fruit and vegetable consumption.

The North Karelia Project fulfilled all of these ambitions. When it started, for example, 86 percent of men and 82 percent of women smeared butter on their bread; by the early 2000s, only 10 percent of men and 4 percent of women so indulged. Use of vegetable oil for cooking jumped from virtually zero in 1970 to 50 percent in 2009. Fruit and vegetables, once rare visitors to the dinner plate, became regulars. Over the project’s official quarter-century existence, coronary heart disease deaths in working-age North Karelian men fell 82 percent, and life expectancy rose seven years.

The secret of North Karelia’s success was an all-out philosophy. Team members spent innumerable hours meeting with residents and assuring them that they had the power to improve their own health. The volunteers enlisted the assistance of an influential women’s group, farmers’ unions, homemakers’ organizations, hunting clubs, and church congregations. They redesigned food labels and upgraded health services. Towns competed in cholesterol-cutting contests. The national government passed sweeping legislation (including a total ban on tobacco advertising). Dairy subsidies were thrown out. Farmers were given strong incentives to produce low-fat milk, or to get paid for meat and dairy products based not on high-fat but on high-protein content. And the newly established East Finland Berry and Vegetable Project helped locals switch from dairy farming—which had made up more than two-thirds of agriculture in the region—to cultivation of cold-hardy currants, gooseberries, and strawberries, as well as rapeseed for heart-healthy canola oil.

“A mass epidemic calls for mass action,” says the project’s director, Pekka Puska, “and the changing of lifestyles can only succeed through community action. In this case, the people pulled the government—the government didn’t pull the people.”

Could the United States in 2017 learn from North Karelia’s 1970s grand experiment?

“Americans didn’t become an obese nation overnight. It took a long time—several decades, the same timeline as in individuals,” notes Frank Hu. “What were we doing over the past 20 years or 30 years, before we crossed this threshold? We haven’t asked these questions. We haven’t done this kind of soul-searching, as individuals or society as a whole.”

Today, Americans may finally be willing to take a hard look at how food figures in their lives. In a July 2015 Gallup phone poll of Americans 18 and older, 61 percent said they actively try to avoid regular soda (the figure was 41 percent in 2002); 50 percent try to avoid sugar; and 93 percent try to eat vegetables (but only 57.7 percent in 2013 reported they ate five or more servings of fruits and vegetables at least four days of the previous week).

Individual resolve, of course, counts for little in problems as big as the obesity epidemic. Most successes in public health bank on collective action to support personal responsibility while fighting discrimination against an epidemic’s victims. [To learn more about the perils of stigma against people with obesity, read “ The Scarlet F .”]

Yet many of public health’s legendary successes also took what seems like an agonizingly long time to work. Do we have that luxury?

“Right now, healthy eating in America is like swimming upstream. If you are a strong swimmer and in good shape, you can swim for a little while, but eventually you’re going to get tired and start floating back down,” says Margo Wootan, SD ’93, director of nutrition policy for the Center for Science in the Public Interest. “If you’re distracted for a second—your kid tugs on your pant leg, you had a bad day, you’re tired, you’re worried about paying your bills—the default options push you toward eating too much of the wrong kinds of food.”

But Wootan has not lowered her sights. “What we need is mobilization,” she says. “Mobilize the public to address nutrition and obesity as societal problems—recognizing that each of us makes individual choices throughout the day, but that right now the environment is stacked against us. If we don’t change that, stopping obesity will be impossible.”

The passing of power to younger generations may aid the cause. Millennials are more inclined to view food not merely as nutrition but also as narrative—a trend that leaves Duke University’s Kelly Brownell optimistic. “Younger people have been raised to care about the story of their food. Their interest is in where it came from, who grew it, whether it contributes to sustainable agriculture, its carbon footprint, and other factors. The previous generation paid attention to narrower issues, such as hunger or obesity. The Millennials are attuned to the concept of food systems.”

We are at a public health inflection point. Forty years from now, when we gaze at the high-resolution digital color photos from our own era, what will we think? Will we realize that we failed to address the obesity epidemic, or will we know that we acted wisely?

The question brings us back to the 1970s, and to Pekka Puska, the physician who directed the North Karelia Project during its quarter-century existence. Puska, now 71, was all of 27 and burning with big ideas when he signed up to lead the audacious effort. He knows the promise and the perils of idealism. “Changing the world may have been utopic,” he says, “but changing public health was possible.”

The Problem of Obesity in the America Essay

Introduction, argument against government intervention, argument for government intervention, analysis of both arguments.

Obesity has been recognized as a national problem in America affecting well over 50% of the population. This condition has been blamed for many a medical complication as well as death in adults. Owing to the prevalence of obesity there have been calls for action to be taken so as to alleviate the condition.

These calls for action can broadly be categorized as government driven initiatives and the personal driven ones. There is contention as to whether the government should be allowed to directly intervene on a person’s eating habits as eating is deemed to be a hugely personal matter.

This paper shall compare two essays; one that opposes government intervention and another one that supports government intervention. The claims advanced by both essays shall be discussed and support offered on behalf of the claims analyzed. This shall be in a bid to ascertain which argument is of a higher quality.

The essay by Balko Bradley proposes that each person should be held accountable for their own diet and lifestyle and that government intervention only serves to absolve a person from taking responsibility for his dietary decisions. The author traces the origins of the problem to the move towards a nationalized health care system which leads to the whole American population collectively bearing the burden caused by the obese population.

Balko insists that this government intervention only serves to “remove the financial incentive for making healthy decisions” since the law dictates that health insurance premiums be kept uniform. This leads to a situation whereby a person who practices a healthy lifestyle is forced to subsidize the cost of the unhealthy lifestyle person.

In my opinion, Balko is not fair in his arguments against government intervention. He begins by somewhat ridiculing the government efforts and takes on a skeptical note as to the success that government interventions would have in reducing obesity prevalence. The author also fails to credibly back up his claims that the current health care system is responsible for the obesity problem and the reader can therefore not able reconcile the health-care system and the obesity problem as the author proposes throughout the essay.

Brownwell and Nestle theorize that the government is responsible for creating an environment in which healthy diets and lifestyles are promoted in the interest or all. This they argue is the only way that the prevalence of obesity in recent years can be curtailed.

The authors begin by stating that the food industry is a profit making enterprise and as such, the industry’s primary objective is increased sales even if at the cost of the public’s health and subsequently proceed to draw parallels between the increase in obesity through the years and the increase in the marketing efforts by the food industry.

Brownell and Nestle also perform a deductive reasoning in their counterclaims against the personal responsibility argument. The authors assert that irresponsibility cannot be on a constant uniform increase across the world as is the case with obesity.

The authors are fair in their arguments since they give both sides of the argument fair thought. They then proceed to refute each opposing view by credible argument. For example, the argument that the food industry only reacts to demand by the consumers is refuted by the authors claim that eating is a biological matter and “humans are hardwired to like sweet foods”.

In my opinion, Brownell and Nestle’s essay presents a superior argument on the matter. The authors make use of statistical information to make their point; this not only reinforces their arguments but it also shows that a lot of research has gone into coming up with the essay. Brownell and Nestle make use of historical events to reinforce their claims.

This is evident in their reference of the tobacco issue which also presented similar arguments; for and against government intervention. The authors assert that just as the reliance on personal responsibility failed in the tobacco case; it is bound to fail in the obesity debate. This historical perspective gives depth to their argument.

On the other hand, the essay by Balko fails to support most of the assertions it makes and also takes on a skeptical tone therefore not appealing to the reader’s intellect. Balko also fails to give any statistical backing to claims such as the role that the health care system plays in advancing obesity. This greatly weakens his arguments.

To the credit of both essays, they do not only restrict themselves to supporting government intervention or opposing it; instead, they also take into consideration the other side of the argument and proceed to point out the fallacies in the opposing views. This enables the reader to know of the other side’s story and therefore make a more informed decision when taking a stand on the matter.

Obesity is a nationwide problem and solutions should be sought before its effects reach catastrophic levels. This paper offered a brief analysis of two essays that propose differing views as to how solving this problem should be undertaken. From the arguments presented herein, it can be proposed that government initiatives aimed at reducing obesity are the best means through which this disaster can be contained.

While appealing to personal responsibility may be the ideal means in a society that is build on the basis of personal freedom, this may prove to be disastrous especially in the face of the aggressive advertisement and marketing schemes undertaken by the food industry players.

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.

Patients Hate ‘Forever’ Drugs. Is Wegovy Different?

Most people, study after study shows, don’t take the medicines prescribed for them. It doesn’t matter what they are — statins , high blood pressure drugs , drugs to lower blood sugar , asthma drugs . Either patients never start taking them, or they stop.

It’s a problem that doctors call nonadherence — the common human tendency to resist medical treatment — and it leads to countless deaths and billions of dollars of preventable medical costs each year.

But that resistance may be overcome by the blockbuster obesity drugs Wegovy and Zepbound, which have astounded the world with the way they help people lose weight and keep it off. Though it’s still early days, and there is a paucity of data on compliance with the new drugs, doctors say they are noticing another astounding effect: Patients seem to take them faithfully, week in and week out.

Some patients may have to get over an initial reluctance to start. A national survey showed that when people were told they would gain weight back if they stopped taking the drugs, most lost interest in starting them.

In one small study, patients stopped refilling prescriptions for months at a time, perhaps because of side effects, lack of availability, or insurance and cost issues.

But anecdotally, doctors and patients say, those who begin taking the drugs are continuing.

“I don’t intend to ever stop taking this medicine,” said Kimberly DelRosso of Pembroke, Mass., who takes Wegovy.

She has never forgotten to take her weekly injection. By contrast, she says, she often neglected to take the blood pressure pills she was prescribed when she weighed more. (Now, after losing weight with Wegovy, she no longer needs them.)

So far, doctors report that like Ms. DelRosso, most of their patients intend to take the obesity drugs forever, and many are thrilled when they stop needing other drugs.

Dr. David Cummings, a professor of medicine at the University of Washington and the director of a weight management program at the V.A. Puget Sound Health Care System, records his patients’ experiences with Wegovy and the diabetes drug Ozempic. So far he has prescribed the drugs to about 1,000 patients. At most 5 percent stopped because of side effects, he said. Others stopped because their insurance no longer covered their drug or because they couldn’t find a pharmacy that had it in stock, reflecting persistent shortages of the drugs.

But those who stop generally do not do so voluntarily, he said. Other doctors who prescribe Wegovy agreed.

“Compliance is exceptional,” said Dr. Diana Thiara, medical director of the weight management program at the University of California, San Francisco. “People take it. They ask for refills. They take it on trips.”

An Epidemic of Nonadherence

There’s a price to pay for neglecting to take prescription drugs. An astonishing 40 to 50 percent of people who are prescribed medicines for chronic conditions like high blood pressure or diabetes fail to take them — and incur at least $100 billion in preventable medical costs annually as a result. This lack of compliance is estimated to lead to at least 100,000 preventable deaths each year.

Even a heart attack may not be enough to scare people into taking the current arsenal of cardiac drugs, shown to prevent heart disease deaths. Some studies show that just half of people who had heart attacks were still taking drugs to protect their heart two years later.

“These patients have seen the bright lights, ridden the ambulance, gotten rescue P.C.I., given their families secondary heart attacks, glimpsed the Pearly Gates, but still don’t seem to take their statins and beta blockers,” said Amitabh Chandra, a professor of public policy and business administration at Harvard.

Even doctors stop taking their meds, defying the hypothesis that people do so because they don’t really understand their importance.

And while cost plays a role, at least one study found that even when drugs are free, adherence can be abysmal.

One reason seems to be a sort of ingrained reluctance to take something that reminds people every day that they are sick, or so many patients might perceive it. Especially with what experts call “forever” drugs, taking them each day makes some patients feel abnormal.

“People think they are doing fine, so they don’t need the medicine,” said Corrine Voils, a social psychologist at the University of Wisconsin who studies medicine compliance. “But the medicine is what is keeping them well.”

Jalpa A. Doshi, a professor of medicine at the University of Pennsylvania’s Perelman School of Medicine, said patients make their own personal value judgments: “The medicine has side effects, requires co-pays, and the act of taking a daily pill reminds me that I’m sick. But I don’t have symptoms — I don’t see my high blood pressure or high cholesterol.”

“And what are the benefits?” she added. “I really can’t see the benefits. I could eat less salt and fatty food and do more walking or exercise,” instead of taking these drugs.

These assessments that patients do in their heads “make it much easier to stop,” Dr. Doshi said.

That describes Mark Anthony Walker, 61, of Dublin, Calif., whose experience with heart disease is shadowed by a troubling family history — his father died of a massive heart attack at age 47, his mother at age 48.

When he was 26, Mr. Walker had a cholesterol level of 360.

“I was terrified,” he said.

He has taken statins on and off ever since and is taking one now. But he does not plan to take it forever. He has come to the conclusion that his brain needs cholesterol. As for taking a drug for the rest of his life, “I am completely against it,” he said.

Instead, he believes he will be able to control his heart disease — even reverse it — with a rigorous diet, exercise and vitamins.

Mr. Walker’s cardiologist, Dr. David J. Maron, the director of preventive cardiology at Stanford, gently encourages him and others like him to take their medicines. But, as doctors know, if they storm in guns blazing, their patients will just go elsewhere.

Less Stigma, Less Shame

So what might be making the obesity drugs different? For one, while doctors are usually the ones to recommend drugs like statins or blood pressure drugs, patients are often asking doctors for obesity drugs. Many have spent a lifetime trying any diet and exercise program they could find, and every time they lost weight, they gained it back again.

Also, people who start taking the new obesity drugs can’t easily hide if they stop taking them: The weight they lost may come back, along with the stigma and shame and self-blame that often accompanies obesity. That makes these drugs very different from most others.

“You don’t get a big sign on your chest saying, ‘Blood pressure medication stopped,’” said Dr. Walid Gellad, a professor of medicine at the University of Pittsburgh who studies medication adherence.

On the minus side, though, the obesity drugs are expensive and often require doctors to fill out burdensome pre-authorization forms for insurance. The drugs have consistently been in short supply around the country. Those impediments can make them difficult to get.

Other drawbacks of the drugs include side effects like nausea and gastrointestinal issues, as well as the way they are administered — patients have to inject themselves with the drugs once a week.

In a study at the Cleveland Clinic, Hamlet Gasoyan and his colleagues examined the electronic health records of 402 patients at sites in Ohio and Florida who were taking Wegovy or Ozempic for obesity. They found that only 161, or 40 percent, had continually refilled their prescriptions over the year. Side effects, availability, or insurance and cost issues may have played a part.

But there’s a reason patients are willing to call dozens of pharmacies looking for the drugs and most faithfully inject themselves every week: Without obesity, they feel that they look better and are viewed differently. No longer are they shunned or shamed. No longer do people stare at their grocery cart or comment when they eat a bowl of ice cream. The embarrassment and self-blame and never-ending stigma of obesity are gone.

That’s a big factor for Ms. DelRosso.

People with obesity “are treated differently,” she said, adding: “It’s just awful how people discount you because you are heavy.”

But she also delights in the health effects. She no longer has sleep apnea or high blood pressure, and her blood sugar, which was edging toward the diabetic range, has fallen.

“I no longer have to take any meds,” she said.

Except, of course, Wegovy.

A Close Look at Weight Loss Drugs

Taking on Weight Stigma: Oprah Winfrey, a prominent figure in the conversation about dieting and weight bias, tackled the rise of weight loss drugs in a new prime-time special . In December, she shared that she was taking a medication to manage her weight.

Beyond Weight Loss: Wegovy is now approved for a new use: reducing the risk of heart attacks , strokes and cardiovascular-related death in adults who have heart disease and are overweight.

Pregnancy: Doctors say they are seeing more women try weight-loss medications in the hopes of having a healthy pregnancy. But little is known about the impact of those drugs  on a fetus.

Muscle Loss: As drugs like Ozempic become increasingly popular for weight loss, more doctors and patients are looking for ways to counteract the muscle loss that can happen on these medications. Companies are racing to meet that demand .
