How Does ‘Eat Less, Move More’ Promote Obesity Bias?

Experts are debating whether and how to define obesity, but clinicians’ attitudes and behavior toward patients with obesity don’t seem to be undergoing similar scrutiny.

“Despite scientific evidence to the contrary, the prevailing view in society is that obesity is a choice that can be reversed by voluntary decisions to eat less and exercise more,” a multidisciplinary group of 36 international experts wrote in a joint consensus statement for ending the stigma of obesity published a few years ago in Nature Medicine. “These assumptions mislead public health policies, confuse messages in popular media, undermine access to evidence-based treatments, and compromise advances in research.”

These assumptions also affect how clinicians view and treat their patients.

A systematic review and meta-analysis from Australia using 27 different outcomes to assess weight bias found that “medical doctors, nurses, dietitians, psychologists, physiotherapists, occupational therapists, speech pathologists, podiatrists, and exercise physiologists hold implicit and/or explicit weight-biased attitudes toward people with obesity.”

Another recent systematic review, this one from Brazil, found that obesity bias affected both clinical decision-making and quality of care. Patients with obesity had fewer screening exams for cancer, less-frequent treatment intensification in the management of obesity, and fewer pelvic exams. The authors concluded that their findings “reveal the urgent necessity for reflection and development of strategies to mitigate the adverse impacts” of obesity bias.

“Weight is one of those things that gets judged because it can be seen,” Obesity Society Spokesperson Peminda Cabandugama of Cleveland Clinic, Cleveland, told Medscape Medical News. “People just look at someone with overweight and say, ‘That person needs to eat less and exercise more.'”

How Obesity Bias Manifests

The Obesity Action Coalition (OAC), a partner organization to the consensus statement, defines weight bias as “negative attitudes, beliefs, judgments, stereotypes, and discriminatory acts aimed at individuals simply because of their weight. It can be overt or subtle and occur in any setting, including employment, healthcare, education, mass media, and relationships with family and friends.”

The organization notes that weight bias takes many forms, including verbal, written, media, and online.

The consensus statement authors offer these definitions, which encompass the manifestations of obesity bias: Weight stigma refers to “social devaluation and denigration of individuals because of their excess body weight and can lead to negative attitudes, stereotypes, prejudice, and discrimination.” 

Weight discrimination refers to “overt forms of weight-based prejudice and unfair treatment (biased behaviors) toward individuals with overweight or obesity.” The authors noted that some public health efforts “openly embrace stigmatization of individuals with obesity based on the assumption that shame will motivate them to change behavior and achieve weight loss through a self-directed diet and increased physical exercise.”

The result: “Individuals with obesity face not only increased risk of serious medical complications but also a pervasive, resilient form of social stigma. Often perceived (without evidence) as lazy, gluttonous, lacking will power and self-discipline, individuals with overweight or obesity are vulnerable to stigma and discrimination in the workplace, education, healthcare settings, and society in general.”

“Obesity bias is so pervasive that the most common thing I hear when I ask a patient why they’re referred to me is ‘my doctor wants me to lose weight,'” Cabandugama said. “And the first thing I ask them is ‘what do you want to do?’ They come in because they’ve already been judged, and more often than not, in ways that come across as derogatory or punitive — like it’s their fault.” 

Why It Persists

Experts say a big part of the problem is the lack of obesity education in medical school. A recent survey study found that medical schools are not prioritizing obesity in their curricula. Among 40 medical schools responding to the survey, only 10% said they believed their students were “very prepared” to manage patients with obesity, and one third had no obesity education program in place with no plans to develop one.

“Most healthcare providers do not get much meaningful education on obesity during medical school or postgraduate training, and many of their opinions may be influenced by the pervasive weight bias that exists in society,” affirmed Jaime Almandoz, MD, medical director of Weight Wellness Program and associate professor of internal medicine at UT Southwestern Medical Center in Dallas. “We need to prioritize updating education and certification curricula to reflect the current science.”

Small wonder that a recent comparison of explicit weight bias among US resident physicians from 49 medical schools across 16 clinical specialties found “problematic levels” of weight bias — eg, anti-fat blame, anti-fat dislike, and other negative attitudes toward patients — in all specialties. 

What to Do

To counteract the stigma, when working with patients who have overweight, “We need to be respectful of them, their bodies, and their health wishes,” Almandoz told Medscape Medical News. “Clinicians should always ask for permission to discuss their weight and frame weight or BMI in the context of health, not just an arbitrary number or goal.”

“Many people with obesity have had traumatic and stigmatizing experiences with well-intentioned healthcare providers,” he noted. “This can lead to the avoidance of routine healthcare and screenings and potential exacerbations and maladaptive health behaviors.”

“Be mindful of the environment that you and your office create for people with obesity,” he advised. “Consider getting additional education and information about weight bias.”

The OAC has resources on obesity bias, including steps clinicians can take to reduce the impact. These include, among others: Encouraging patients to share their experiences of stigma to help them feel less isolated in these experiences; helping them identify ways to effectively cope with stigma, such as using positive “self-talk” and obtaining social support from others; and encouraging participation in activities that they may have restricted due to feelings of shame about their weight.

Clinicians can also improve the physical and social environment of their practice by having bathrooms that are easily negotiated by heavier individuals, sturdy armless chairs in waiting rooms, offices with large exam tables, gowns and blood pressure cuffs in appropriate sizes, and “weight-friendly” reading materials rather than fashion magazines with thin supermodels.

Importantly, clinicians need to address the issue of weight bias within themselves, their medical staff, and colleagues, according to the OAC. To be effective and empathic with individuals affected by obesity “requires honest self-examination of one’s own attitudes and weight bias.”

Almandoz reported being a consultant/advisory board member for Novo Nordisk, Boehringer Ingelheim, and Eli Lilly and Company. Cabandugama reported no competing interests.
