I heard there was a piece on "Genetics Of Eating Disorders" ran on a day time talk show.
It would make pretty good sense, although my mom suffers from every sign of an eating disorder, she has NEVER come out and said it. At the same time, I have come out, asked for help and she ignores it of me.
Its a bit daunting to think that this behavior is permanent, thus making it incurable.
