The condition of not eating out of self-starvation is known as Anorexia Nervosa. It is a serious eating disorder characterized by a distorted body image, an intense fear of gaining weight, and a refusal to maintain a healthy weight. People with anorexia nervosa often have a low body weight, a preoccupation with food, and a distorted perception of their body shape and size. It is a complex condition that requires professional help and treatment.
