Bulimia can make someone gain weight by altering their appetite regulation so that, for instance, each time you have a binge eating episode when you regurgitate, you're only absorbing maybe twenty to thirty percent of the food that you eat. Your body has needs for that day and meanwhile your body is supposed to be regulating your appetite, and regulating your food intake. By bingeing and regurging, you're going to be eating five or six times the number of calories that you really need during that day so the chance for overshooting is almost a hundred percent, which is why most patients with bulimia nervosa are up to ten percent higher in their weight.
