How do I know that two years from now your program will not turn out to be like the Ornish/Atkins diets that initially produce great results?
The Zone diet is not a diet, but a life-long hormonal control program that allows you to maximize your full genetic potential. Both the Ornish and Atkins diets are based on gluttony. Either eat all the carbohydrate you want (i.e. Omish) or all the protein and fat you want (i.e. Atkins). The Zone diet is based on moderation because of the limits on the amount-of protein, carbohydrate, and fat consumed at every meal.
