Which eating disorder is known for its restrictive behavior leading to low body weight?

Anorexia Nervosa is characterized by restrictive eating behaviors that result in significantly low body weight, often defined by the individual being below the minimum normal weight for their age and height. This disorder involves an intense fear of gaining weight, a distorted body image, and persistent behaviors that interfere with weight gain, even when the individual is underweight.

Individuals with Anorexia Nervosa may engage in various restrictive practices, such as severe calorie restriction, excessive exercise, and various purging behaviors, although not all individuals will engage in purging. The key elements of this disorder emphasize both the behavior of restricting food intake and the ensuing low body weight, which is critical to its diagnosis.

In contrast, Bulimia Nervosa involves episodes of binge eating followed by compensatory behaviors to prevent weight gain, but individuals typically maintain a body weight that is within or above the normal range. Rumination Disorder entails the regurgitation of food, which may or may not be re-chewed or re-swallowed, and does not primarily involve weight-loss behavior. Feeding Disorders, typically seen in children, may reflect difficulties in eating patterns but are not diagnosed based on restrictive behaviors leading to low body weight.
