Just because "bigger ladies are in" doesn't mean it's not overweight. my doctor seems to think that i'm overweight too. i have a feeling that i see a look on her face and she asks if i exercise. i am 5'2 and weigh 156. i don't look overweight. I think that it is ridiculous that she wants me to eat several more times a day just because i sometimes nearly pass out.
You could really just be big boned, but i think that the doctor could easily determine if that is the case. It's fine to accept yourself and be happy with yourself, but don't run away from facts that determine a healthy weight range. Also, if the doctor is rude, then make sure to get a different doctor.
