The difference with bulimia nervosa and binge-purging anorexia nervosa is subtle but is there, retard.
Bulimia nervosa: You binge and then vomit because you don't want to gain weight but you weight actually stays stable and somewhat healthy.
Anorexia nervosa binge-purging type: Your primary goal is to lose weight, so you try to starve yourself, keep exercising and walking like a nutso all day, use laxatives and god knows what in order to lose weight... but the hunger wins so after starving yourself for a while you binge, but feel guilty, you vomit, and the cycle repeats: net effect you lose weight and become full blown anorexic.
Anorexia nervosa Restricting type: You just don't eat, never. And still have all those behaviors that make you lose weight faster. Probably the most dangerous type without medical attention.
There you go faggot, here's your free lesson on the topic, enjoy. She's most likely the binge-purging type
