"The Simple Diet," is an even more affordable meal replacement option using grocery store alternatives. The book is written by a doctor who is not only a weight loss researcher, but also a weight loss patient. His coauthor is a dietitian.
Like the New Lifestyle Diet, The Simple Diet is modeled after HMR ( Health Management Resources, a weight loss product and services company used in medical weight loss programs in hospitals and medical schools).
The Simple Diet gives calorie, protein, and fat guidelines for selecting, making, and using shakes, soups, bars, and entrees (and for selecting the fruits and vegetables required).
