An example of this is Chris Powell's method. Chris goes back and forth between high and low carb days three times a week, for a total of six days. The seventh day he calls the “guilt-free day,” which allows everyone to eat whatever they want. It soothes the physiological need linked to the way people eat. Chris believes, as do I, that no diet will ever work if the person doing the diet feels depressed, deprived or restricted. This is why the carbohydrate recycling diet is so successful for so many people. The body gets what it needs, but on a planned schedule so that fat is burned.
