I didn't disagree with what you said, and I think you are totally right about evolutionary roots.  We seem to be discussing several different things here.  A woman's conception of her body is different than how attractive she may be to a man.  Even when I feel slightly overweight, I feel unattractive inside, even though it may actually accentuate my curves and make me more attractive to men.  I do think this conception of myself has been influenced by the preponderance of young thin women in the media, for better or worse.  My awareness of it doesn't seem to completely erase the feeling.  Since I am short and curvy, if I wear loose clothes (or all the clothes we need in the Pacific Northwest to keep warm), I tend to look "fat."   ; But whatever ;)
