A San Diego physician Dr. Mike Moreno’s initiated this weight-loss regimen. Already a best seller, his new book professes the power of the number 17. With 17 minutes of daily exercise and four different 17-day meal plan cycles, the diet promises dramatic weight loss results for life. Broken into four different parts, the plan is designed to jump-start the body’s metabolism by switching up eating habits every 17 days. The first cycle involves a restrictive calorie diet, and the other three toggle between various carbs, proteins, fruits and veggies for an overall healthy makeover.
