David tells you what to eat and when. He does incorporate snacks into the plan along with all your meals for the whole two weeks. I'm just not organized enough to buy and prepare the foods in advance. And, then, being a teacher, I couldn't just bust out the snacks and eat in front of the kids when I'm supposed to eat. I do have to admit, though, that I do eat many of his recipes frequently. And, yes, it is VERY CLEAN eating. The boy does know what he's talking about!!!!
