Which of the following is NOT a typical characteristic of anorexia nervosa?

C is the correct answer because individuals with anorexia nervosa often exhibit extreme restrictions in food intake and have a distorted body image that leads them to perceive themselves as overweight, even when they are underweight. This condition is characterized by an obsession with thinness and attempts to lose weight through various unhealthy practices. Therefore, healthy eating habits do not align with the typical behaviors exhibited by someone suffering from anorexia nervosa, which primarily includes restrictive eating and avoidance of food.

In contrast, excessive exercise is commonly seen as a method to burn additional calories in an effort to control weight and maintain a low body mass. The intense fear of weight gain and denial of having a low body weight are hallmark features of anorexia nervosa, as these individuals often cannot recognize the severity of their condition or the implications of their low weight. Healthy eating habits, on the other hand, would involve a balanced and appropriate intake of food, which contradicts the maladaptive behaviors associated with this eating disorder.
