What is the primary difference between anorexia nervosa and bulimia nervosa?

A key difference is body weight: people with anorexia nervosa are typically significantly underweight, while people with bulimia nervosa are often at a normal weight. Bulimia involves recurrent binge eating and compensatory behaviors, such as vomiting or excessive exercise, which may prevent major weight loss. The other choices describe differences that are not generally accurate.
