Question

BlackTom AI · Accepted Answer

Consider the question: Which eating disorder is best characterized by self-imposed starvation in an effort to lose weight?

Option 1: Pica. This disorder involves persistent eating of non-nutritive substances (such as dirt, clay, or ice) and does not center on weight loss through starvation. The behavior is about the type of substance, not caloric restriction, making this an incorrect fit for the described pattern.

Option 2: Anorexia nervosa. This condition is classically defined by extreme restriction of food intake leading to significantly low body weight, an intense fear of gaining weight, and a distorted body image. The emphasis on self-imposed starvation to lose weight aligns directly with the core feature of this disorder.

Option 3: Binge-eating disorder. Here the hallmark is recurrent episodes of eating large quantities of food with a sense of loss of control, but without the regular compensatory behaviors (such as vomiting) that characterize some other disorders. Weight loss through starvation is not the defining mechanism in this pattern.

Option 4: Bulimia nervosa. This disorder involves recurrent binge eating episodes followed by compensatory behaviors like purging, excessive exercise, or misuse of laxatives. Although weight concerns are central, the defining feature is the binge-purge cycle, not consistent self-imposed starvation as the sole strategy for weight loss.

Summarizing the distinctions, only the described self-imposed starvation to lose weight maps directly onto anorexia nervosa, whereas the other options describe different eating behaviors or concerns that do not match the focal pattern of self-starvation for weight loss.
