Why iDiet Works
Meet Dr. Roberts
Created by Susan Roberts, PhD, of Tufts University, the iDiet is based on advanced clinical research and helps dieters change their total approach to food, without hunger and without deprivation.
Dr. Roberts, author of the groundbreaking book The “I” Diet and more than 200 clinical studies on nutrition and weight loss, decided she had to become a “diet doctor” because she had discovered the secret to lifelong weight loss…and lives transformed.
Dr. Roberts has collapsed her advanced nutrition science down into simple, doable, delicious menus. To succeed on the iDiet, all you have to do is follow the menus. And because Dr. Roberts worked as a chef before her career as a scientist, her iDiet recipes are delicious.
