It's yet another high protein shake twice per day plus one high protein/no carb "normal" meal. As a carbo addict I do understand the science behind this eating/lifestyle plan but you can get the same results by eating three high protein/no-lo carb meals too. And you don't have to pay a fortune for the "miracle" shakes. This is basically the Atkins diet. Once you understand the theory it's very easy to follow and you can make your own meals for a fraction of the price of these meal replacement shakes.
