As a practicing general surgeon, I would like to point out that while obese people are coming to grips with their body images, they are also killing themselves. Just about everything involving medical care is exceedingly more difficult in the obese patient from the simple acts of having blood drawn, IVs inserted and blood pressure measured accurately to undergoing and recovering from even basic operations such as appendectomies.
Obesity is linked to decreased life expectancy and higher rates of diabetes, cancer, lung disease, hypertension and death from all causes. Finally, the cost of medical care is significantly higher for the obese. Compared to health, the clothing issue is of miniscule importance.
