It’s as true in the medical field as it is in the social and professional realms: Your weight has a big impact on how you are perceived. Doctors readily admit to judging their fat patients. A 2003 survey of 620 primary care physicians found that more than half viewed obese patients as “awkward, unattractive, ugly, and non compliant.” As terrible as it is to be denied a promotion or receive poor service at a restaurant because of your size, being diagnosed through the lens of a doctor’s weight bias could be lethal.
