About the iDiet


The iDiet is a transformational, easy-to-follow program for healthy, hunger-free and long-term weight loss. The iDiet is based on more than 20 years of research and clinical trials and has been called “the most comprehensive approach to eating for effective weight control” by the New York Times.

The iDiet helps to retrain your brain™ for healthier eating and effortless weight loss by forming new food habits and new healthier cravings. fMRI scans have shown that brain activity in iDiet participants actually changes in response to food options, and that iDieters prefer healthier vs fattening foods over time.

The iDiet has been recommended by doctors for patients looking for:

  • Long-term weight control
  • Increased energy level
  • Lower cholesterol levels
  • Reduced blood pressure
  • Reduced aches and pains
  • Prevention or treatment of Type 2 diabetes
  • Improved blood sugar levels

The iDiet programs are facilitated by an iDiet-trained Group Leader. The educational, fun and supportive group process leads to a typical weight loss of 25 pounds over 24 weeks.

The iDiet was developed by internationally renowned scientist Susan Roberts, PhD, Professor of Nutrition at Tufts University, and Professor of Psychiatry and Scientific Staff Member in Pediatrics at Tufts Medical Center. Dr. Roberts has focused on the neurobiology of eating to make weight loss “instinctive.” She is the author of over 200 research papers on weight control, as well as the coauthor of “The I Diet” (Workman Publishing 2010) and this online weight loss program based on her life’s work. Her program has been endorsed by top weight loss experts and health care professionals.
