Fast Diet

NYTimes reported a new diet craze in England. The book, "The Fast Diet", is an instant best-seller since its introduction in January 2013. Why does it caught all this frenzy? Because it said that you can eat anything you want as long as you fast 2-days in a week. Personally I find this is nothing new since it is similar to the diet concept of "Calorie Restriction" that I describe on the post about Key Concepts in Healthy Diet.
