This essay explores the complex, multi-layered causes of obesity in the United States, where roughly one-third of adults and one-fifth of youth are classified as obese. Rather than accepting the medical establishment's framing of obesity as a standalone disease, the paper argues that blame is shared among obese individuals whose lifestyle habits contribute to chronic weight gain, healthcare providers who over-prescribe medication instead of encouraging behavioral change, and policymakers who have failed to address food access disparities and community design. The essay also challenges the dominant narrative that genetics is the primary driver of obesity, contending that environment, behavior modeling, and socioeconomic conditions are far more influential factors.
Obesity is a tremendous public and personal health issue, with a full third of all adult Americans and one-fifth of all American youth classified as obese (Centers for Disease Control and Prevention). The problem of obesity has been well documented in the mainstream media as well as in scholarly literature. However, the causes of its widespread prevalence are controversial and remain unresolved. Most medical sources classify obesity as a "disease" rather than as a symptom of underlying problems. This classification seems counterintuitive — and it is — given the strong likelihood that the medical establishment uses the "disease" label to enable the promulgation of goods and services that bolster the healthcare industry. In fact, doctors and other healthcare providers are not doing enough to curb the problem of obesity in America and are partly to blame for it.
Obesity is often exacerbated by genetic and physiological factors beyond the individual's control. Yet a person's lifestyle habits have far more to do with the phenomenon of obesity, which refers not merely to being slightly heavy, but to being dangerously overweight to the point of experiencing additional health symptoms. Because obesity is burdening an already strained healthcare system, it is important to assign responsibility in the hopes of prompting policy change. The blame for obesity is shared among those who are obese — whose lifestyle habits lead to chronic weight gain — and those who are part of the healthcare establishment, including the politicians who support them.
Individual blame must be accepted in most cases of extreme obesity. There will always be exceptional cases that defy doctors' ability to help a patient lose weight. However, most people who are morbidly obese have at least some role to play in the way their body metabolizes food. There is only so much an obese person can attribute to genetics before it becomes clear that a genetic predisposition to obesity does not necessarily mean a person will become morbidly obese. A person can be heavier than the American aesthetic norm without being unhealthy. The problem with obesity is not aesthetics but health: obese Americans are burdening the healthcare system with largely preventable conditions.
Doctors are partly to blame for the obesity epidemic. Many refuse to prescribe lifestyle changes for their patients. Instead, they are too willing to prescribe medications that allow patients to continue eating fast food and avoiding exercise. A person who eats excessive amounts of fast food and never exercises is likely to gain weight — and may become obese if genetically predisposed. All healthcare workers, including nurses, can take a more active role in preventing obesity by recommending lifestyle changes to their patients. Prescribing drugs is part of the problem, not part of the solution.
Obesity is far more related to lifestyle choices than to faulty genes. If genetic defects were primarily responsible for obesity, the condition would appear at similar rates across the world's diverse societies. Instead, obesity tends to emerge in cultures that become wealthy and adopt fast-food consumption patterns — a pattern that strongly implicates environment and behavior over biology.
Doctors are also responsible for promoting the myth that obesity is related more to genetics than to lifestyle by misrepresenting statistics about the condition. As WebMD notes, "If one of your parents is obese, you are three times as likely to be obese as someone with parents of healthy weight." What that claim fails to mention is that the reason parents pass obesity on to children may have nothing to do with genes at all, but rather with shared lifestyle habits and behavior modeling. A child who grows up watching a parent eat potato chips and fast food while watching television may simply model that behavior. If the parent is obese, the child may become obese not necessarily because of genetics, but because of learned behavior.
