There’s evidence that FDA-approved diet drugs actually work, so why don’t physicians prescribe them very often? The answer may have to do with our complicated views about obesity:
Obesity is potentially, in part, a neurological disease. Jeffrey Flier, an endocrinologist and dean of Harvard Medical School, has shown, like others, that repeatedly eating more calories than you burn can damage the hypothalamus, an area of the brain involved in eating and satiety. In other words, Big Gulps, Cinnabons, and Whoppers have altered our brains such that many people—particularly those with a genetic predisposition to obesity—find fattening foods all but impossible to resist once they’ve eaten enough of them. Louis J. Aronne, director of the Comprehensive Weight Control Program at New York-Presbyterian/Weill Cornell Medical Center, explained to me, “With so much calorie-dense food available, the hypothalamic neurons get overloaded and the brain can’t tell how much body fat is already stored. The response is to try to store more fat. So there’s very strong scientific evidence that obesity is not about people lacking willpower.”
But this message has not found its way into society, where obese people are still often considered self-indulgent and lazy, and face widespread discrimination.
Several obesity experts told me they’ve encountered doctors who confide that they just didn’t like fat people and don’t enjoy taking care of them. Even doctors who treat obese patients feel stigmatized: “diet doctor” is not a flattering term. Donna Ryan, who switched from oncology to obesity medicine many years ago, recalls her colleagues’ surprise. “I had respect,” she says. “I was treating leukemia!”
George Bray … of the Pennington Biomedical Research Center, thinks that socioeconomic factors play into physicians’ lack of enthusiasm for treating obesity. Bray points to the work of Adam Drewnowski at the University of Washington, who has shown that obesity is, disproportionately, a disease of poverty. Because of this association, many erroneously see obesity as more of a social condition than a medical one, a condition that simply requires people to try harder. Bray said, “If you believe that obesity would be cured if people just pushed themselves away from the table, then why do you want to prescribe drugs for this non-disease, this ‘moral issue’? I think that belief permeates a lot of the medical field.”
