Can 'Big' Be Healthy? Yes -- and No

This month, while many people were committing to their New Year’s resolutions to lose weight, Cosmopolitan UK magazine released covers portraying 11 women of different shapes and sizes, with the headline, "This is healthy!" Each version of the cover features one or more of the 11 women wearing athletic gear and makeup, some of whom are caught mid-action — boxing, doing yoga, or simply rejoicing in being who they are. Seeing these, I was reminded of a patient I cared for as an intern.

Janet Spears (not her real name) was thin. Standing barely 5'3", she weighed 110 pounds. For those out there who think of size in terms of body mass index (BMI), it was about 20, solidly in the "normal" category. At the age of 62, despite this healthy BMI, she had so much plaque in her arteries that she needed surgery to improve blood flow to her foot.

Admittedly, whenever I had read about people with high cholesterol, type 2 diabetes, or atherosclerosis, I pictured bigger people. But when I met Ms Spears, I realized that one's health cannot necessarily be inferred from physical appearance.

As a bariatric surgeon board certified in obesity medicine, I've probably spent more time thinking and learning about obesity than most people — and yet I still didn't know what to make of the Cosmopolitan covers.

I saw the reaction on Twitter before I saw the magazines themselves, and I quickly observed a number of people decrying the covers, suggesting that they promote obesity:

Multiple people suggested that this was inappropriate, especially in the context of the COVID-19 pandemic and the fact that people with obesity are at risk for worse outcomes compared with those without obesity. (As an aside, these comments suggest that people did not read the associated article, which is about fitness and body image more than it is about obesity.)

Does Size Reflect Health?

Putting the pandemic aside for a moment, the question the magazine covers raise is whether physical appearance reflects health. That's what got me thinking about Ms Spears, who, though appearing healthy, was sick enough that she needed to have major surgery. This whole conversation hinges, of course, on one's definition of health.

A common knee-jerk response, especially from physicians, would be to say that obesity is by definition unhealthy. Some researchers have suggested, though, that a segment of people with obesity fall into a category called metabolically healthy obesity, which is typically characterized by a limited set of data such as cholesterol, blood sugar, and blood pressure. Indeed, some people with obesity have normal values in those categories.

Being metabolically healthy, however, does not preclude other medical problems associated with obesity, including joint pain, cancer, and mood disorders, among other issues. So even those who have metabolically healthy obesity are not necessarily immune to the many other obesity-related conditions.

What About Body Positivity?

As I delved further into the conversation about these covers, I saw people embracing the idea of promoting different-sized bodies. With almost two thirds of the US population having overweight or obesity, one might argue that it's high time magazine covers and the media reflect the reality in our hometowns. Unrealistic images in the media are associated with negative self-image and disordered eating, so perhaps embracing the shapes of real people may help us all have healthier attitudes toward our bodies.

That said, this idea can be taken too far. The Health at Every Size movement, which some might consider to be the ultimate body positivity movement, espouses the idea that size and health are completely unrelated. That crosses a line between what we know to be true — that at a population level, higher weight is associated with more medical problems — and fake news.

Another idea to consider is fitness, as opposed to health. Fitness can be defined multiple ways, but if we consider it to be measured exercise capacity, those who are more fit have a longer life expectancy than those with lower fitness levels at a given BMI. While some feel that the Cosmopolitan covers promote obesity and are therefore irresponsible, it's at least as likely that highlighting people with obesity being active may inspire others with obesity to do the same.

Now let's bring the pandemic back into the picture. As much as we all wish that it was over, with uncontrolled spread in every state and record numbers of people dying, COVID-19 is still very much a part of our reality. Having obesity increases the risk of having a severe case of COVID-19 if infected. Patients with obesity are also more likely than those without obesity to be hospitalized, require intensive care, and die with COVID-19.

Guiding the Conversation

Pandemic or not, the truth is that obesity is related to multiple medical problems. That does not mean that every person with obesity has medical problems. The musician Lizzo, for example, is someone with obesity who considers herself to be healthy. She posts images and videos of working out and shares her personal fitness routine with her millions of fans. As a physician, I worry about the medical conditions — metabolic or otherwise — that someone like her may develop. But I love how she embraces who she is while striving to be healthier.

Most of the critical comments I have seen about the Cosmopolitan covers have, at best, bordered on fat shaming; others are solidly in that category. And the vitriol aimed at the larger models is despicable. It seems that conversations about obesity often vacillate from one extreme (fat shaming) to the other (extreme body positivity).

Although it may not sell magazines, I would love to see more nuanced, fact-based discussions, both in the media and in our clinics. We can start by acknowledging the fact that people of different sizes can be healthy. The truth is that we can't tell very much about a person's health from their outward appearance, and we should probably stop trying to make such inferences.

Assessment of health is most accurately judged by each person with their medical team, not by observers who use media images as part of their own propaganda machine, pushing one extreme view or another. As physicians, we have the opportunity and the responsibility to support our patients in the pursuit of health, without shame or judgement. Maybe that's a New Year's resolution worth committing to.
