>>40256694 (OP)I don't get anorexics thinking it helps them pass. Nothing clocks a doll faster than low body fat %, its quite noticeable, look at the right one's legs and forearms. Defined muscle tone without cover fat is distinctly male. If the right one put on 10% more BMI, she'd likely be total passing.
Contrast against blob-hons. Get high enough BMI and you just look indistinguishable from a woman, a fat woman, but a woman.
