I knew eventually they'd find the male counterpart to eating disorders, and it seems that now they have. I saw a Discovery show on this awhile back. Guys will go through the most extreme training regiments imaginable and will still think they don't look right. Most of them are eventually forced to stop because they injure themselves.
It all seems to boil down to a variant of obsessive-compulsive disorder (OCD). Hopefully we won't get "pro dysmorphia" sites like we do with the lunatic eating disorder fringe. HELLO PEOPLE they call it a disorder for a reason!
