Anorexia Recovery & Treatment

I’ve never quit understood. I know the whole purpose of Anorexia is to starve yourself… but wouldn’t you become desperate of food? If you have had personal experience, please explain to me how they can possibly go this long feeling starved!

I’ve heard that recovering from anorexia is a process in which one has to “wheedle oneself back up”, but that’s a little vague. How large of a calorie increase and how gradually should this be done in order to not gain weight? And is there more to it than that…?
