I do not see any choices but I will give you background on anorexia nervosa- This is basically compulsive exercise and weight loss. Basically this is when people keep keep keep working out and they are at a very low bodyweight . I had a problem with this when I was younger and would not eat. Hope this helps
Have a schedule, some kind of goal, some kind of reward along the way.
