Based on physician Michael Rafael Moreno’s 2011 book, "The 17 Day Diet: A Doctor’s Plan Designed for Rapid Results," the 17 Day Diet is divided into, three 17-day cycles followed by a final maintenance phase. While the plan doesn't completely nix certain foods, there are suggestions and restictions.

 

The first phase is a low-carb, high-protein stint of only 1,200 calories; the following stages mix up the eating and exercise regimen to create “calorie cycling” — which is conceived as a way to keep the metabolism revved up and to avoid the dreaded plateau. While this theory may not be scientifically proven, the balanced meals and exercise provide a sensible way to shed the weight. 

 

“Everyone wants fast results and the calorie confusion of this plan burns fat, achieves weight loss results, and helps dieters avoid boredom," says Moreno. So if you tend to get bored on diets, this one may have your name on it.
