SAN MATEO, Calif.--(BUSINESS WIRE)--A pilot study published today in Communications Medicine demonstrates the potential of a new approach to treating anorexia nervosa — a disorder for which effective treatments have been significantly limited. The research from UC San Diego School of Medicine reports that a ketogenic nutritional intervention — a high-fat, low-carbohydrate, moderate-protein diet — was feasible and safe for patients with weight-normalized and mildly underweight anorexia nervosa.
