Which eating disorder is characterized by an irrational fear of gaining weight, leading individuals to starve themselves?

Anorexia Nervosa is characterized by an intense fear of gaining weight and a distorted body image, which drives individuals to restrict their food intake to the point of starvation. People with this disorder often see themselves as overweight, even if they are dangerously underweight, leading to extreme weight loss and potentially severe health issues. The behavior associated with anorexia includes not only restriction of food but also excessive exercise and other methods to prevent weight gain. This fear and behavior are central to the diagnosis of anorexia, making it distinct from other eating disorders that may involve different eating patterns or behaviors.
