Unlike other eating disorders, people with ARFID:

• They do not verbalize fear of weight gain (they may be underweight, normal weight or overweight) nor distortion of body image .
• They do not reject food because of its caloric content nor do they have persistent behaviors (vomiting, excessive physical exercise, use of laxatives, among others) that interfere with their weight gain.
• Although it can be diagnosed at any age, compared to other eating disorders, ARFID usually starts in childhood and is more common in boys than in girls.
• They report a longer disease evolution time, which entails a greater risk of long-term chronicity.
