I hear you. I'm 5'9" with a *very* big frame and a tendency to gain muscle mass easily (our family makes jokes about being from "peasant stock"). Not very fashionable for a woman to be, but hey, you play the hand you're dealt.

According to the BMI charts, my ideal weight is about 125-135lbs. Yet my doctor jokingly threatened to kill me herself if I let myself go under 170lbs. Believe me, at 170 I look *very* skinny -- my friends underestimate my weight by 30-40lbs, and they're not trying to flatter me.

I am completely convinced BMI is bunk. There are simply too many exceptions to the rule.
