Individuals with anorexia nervosa have a fear of gaining weight, despite the fact that they are typically underweight. The DSM-5 describes this perceptual symptom as "disturbance in the way in which one's body weight or shape is experienced". Recent research has shown that this disturbance is based not on visual body-size overestimation but rather on body dissatisfaction: individuals with anorexia can accurately visually identify their body size, but find severely underweight bodies the most attractive. Individuals with anorexia nervosa may also deny that their symptoms or behaviors are indicative of illness. They may weigh themselves frequently, eat small amounts, and only eat certain foods in order to be in as much control of their body appearance as possible.

Anorexia nervosa has the highest mortality rate of any psychiatric diagnosis.…
