Anorexia Nervosa is an eating disorder and possibly life-threatening disorder if not treated on time. We here report an unusual case of a 14 year old boy with anorexia nervosa who had significant weight loss over a period of two years. This case report narrates the nutrition intervention and the challenges encountered by the dietitian to improve the nutritional status of the patient. A significant weight gain was achieved from 29kg to 42 kg over a period of two months with an intense nutritional therapy.
