Grossly deficient in most aspects, people suffering from Anorexia Nervosa, would also understand the slimiest of people to be overweight.
What is Anorexia Nervosa?
Anorexia nervosa is a serious, often chronic, and life-threatening eating disorder defined by a refusal to maintain minimal body weight within 15 percent of an individual's normal weight. Other essential features of this disorder include an intense fear of gaining weight, a distorted body image, and amenorrhea (absence of at least three consecutive menstrual cycles when they are otherwise expected to occur). In addition to the classic pattern of restrictive eating, some people will also engage in recurrent binge eating and purging episodes. Starvation, weight loss, and related medical complications are quite serious and can result in death.
