神経性無食欲症
Evolutionary perspectives exist on Anorexia nervosa (henceforth ‘anorexia’) and Bulimia nervosa (henceforth ‘bulimia’). Anorexia is characterized by restriction of food intake, bulimia by cycles of binging (excessive eating) and purging (forced removal of the food). Both are associated with body shape and physical attractiveness concerns.
