Angie, the books are a exy in as much as they are just pamphlets. But the Food Guide one would be worth getting as it tells you exactly what you are allowed and not allowed.

In a nutshell it is one shake at breakfast, one shake at lunch, then a heathy dinner with no carbs. Then you are allowed "snacks" from the list of allowable foods.

Have you checked Ebay? I noticed that the books come up on there for a bargain.......

Either way, very best of luck........
