What is the primary characteristic of Anorexia Nervosa?

The primary characteristic of Anorexia Nervosa is the severe restriction of calorie intake to the point of starvation. Individuals with this eating disorder have an intense fear of gaining weight and a distorted body image that leads them to see themselves as overweight even when they are underweight. This results in extreme dietary restrictions and often an obsession with body weight, exercise, and food. The behavior can lead to significant health issues, including malnutrition, organ damage, and in severe cases, it can be life-threatening.

In contrast, the other options describe different eating disorders or normal behaviors. Engaging in excessive binging followed by purging is characteristic of Bulimia Nervosa. Compulsive eating without purging suggests Binge Eating Disorder, where individuals consume large amounts of food without the compensatory behaviors seen in bulimia. Following a balanced diet strictly does not relate to any eating disorder; instead, it represents a healthy eating practice. Thus, the extreme caloric restriction associated with Anorexia Nervosa makes it a distinct and serious condition.
