If I am at the highest weight recommended per BMI I am, at 5'5", 150 pounds and a 12 - 14. It is certainly not the weight or look of a Hollywood waif, and is achievable.
I think there are a bunch of problems going on with weight.
First, a healthy weight has nothing to do with looking like the anorexics on the silver screen.
Second, being thin is a sign of higher socioeconomic status, which contributes to the overweight being looked down on.
Third, there is a difference between being a bit chubby and being obese. It is possible, but not usual, to be slightly obese and healthy. The lobby of the morbidly obese, led by the idiot Paul Campos and his acolytes at Big Fat Blog, misinterpret any findings that, say, correlate slightly higher weight than is deemed ideal with increased longevity, to mean that being morbidly obese is fine. It is not.
I think the new surgeon general looks great. I do not think that her personal struggle with anything needs to be made public.
