Which disorder is defined as an eating disorder characterized by a persistent restriction of energy intake leading to significantly low body weight?

• A. Anorexia nervosa
• B. Bulimia nervosa
• C. Sleep Disorders
• D. Facitious disorder

Answer: (A)

A persistent restriction of energy intake leading to significantly low body weight points to anorexia nervosa. This condition revolves around actively limiting the amount of food eaten to the point that weight falls well below what’s appropriate for age, sex, and development, often with an intense fear of gaining weight and a distorted view of one’s body. That focus on restriction and underweight distinguishes it from bulimia nervosa, which involves binge eating with compensatory behaviors and can occur at normal or fluctuating weight. Sleep disorders deal with sleep-related problems, not sustained weight loss from restricted eating, and factitious disorder involves feigning or inducing symptoms, not true restrictive eating for weight control.
