Final answer:
People attempting to become extremely thin by significantly reducing their food intake likely suffer from anorexia nervosa, an eating disorder characterized by a severe restriction of calorie intake and a distorted body image.
Step-by-step explanation:
People who are attempting to become extremely thin by significantly reducing what they eat suffer from anorexia nervosa. Anorexia nervosa is an eating disorder characterized by individuals consistently eating very little and becoming extremely thin.
They typically have an obsessive fear of gaining weight and an unrealistic perception of their own body weight, seeing themselves as overweight even when they are very underweight. It is common for people with anorexia nervosa to also have body dysmorphic disorder, where there is dissatisfaction with their body size and shape. In contrast, bulimia nervosa involves episodes of binge eating followed by compensatory behaviors such as vomiting, using laxatives, or excessive exercising. Binge eating disorder is where individuals compulsively overeat without the compensatory behaviors, often leading to obesity.
