“Perhaps the most comprehensive approach to eating for effective weight control.”

— Jane E Brody, The New York Times

“I was never hungry and I never felt deprived while dieting. I find it to be freeing.”


“When I hit the 50lbs loss mark, I was very proud of my accomplishment.”


“The iDiet has been a life changing experience for me. The science makes sense. The recipes are fantastic. I went from being 312 lbs to 185 lbs in 24 weeks.”


“The program has completely changed my relationship with food. iDiet is science-based and aimed at helping control cravings. My cravings are reduced to nearly nothing. I have lost 15 pounds and feel much better, in control and healthier.”


“I am amazed by the iDiet. It surpassed my goals. I am happy to say I lost more weight than I originally planned.”


“To my surprise and utter delight, the weight began coming off immediately, and after the first two weeks of the program, I had lost 10 pounds!”


“The other programs that I have tried – WW in particular – did not give me the longer term skills that the iDiet gave me.”


“I don’t worry about my weight anymore. I now have the tools to maintain a healthy weight.”


“Before I knew it, after 20 weeks of the program I had lost 45 pounds and was eating healthier than I had ever before. The iDiet truly worked!”


“With the iDiet education I am now finally aware of what my body is doing when I see and smell food and how, not to fight nature, but to work with it and feed myself in a healthy purposeful manner.”


“I have tried many diets in the past but the iDiet just works.”


“The iDiet program has been the first diet on which I have lost weight. I lost 45 lb and I’ve referred at least 8 people to the program, all of whom have lost weight. The program is a life changer!”


“Almost three months now since starting the maintenance phase, I’m holding steady with my weight. Thank you Dr. Roberts and the iDiet!”


“After losing 40 pounds along side me while I was dieting, my husband just started in his own iDiet group to continue his weight loss. He also was amazed at how well the iDiet worked for him.”

Meet Dr. Roberts

landing_meet dr robertsCreated 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.
landing_book the i dietDr. 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.
