I was excited to receive this book and see what all of the buzz is about. It gives a nice overview of the plan and the basics you need to get started. I think the one thing I liked about this book as it did have a lot of helpful information on what to eat and what not to eat. I was a little disappointed with the books use of on plan foods and ingredients. Many are found at specialty stores. This is not a book about eating whole foods found in your supermarket. You use a fair amount of fake sugar, oat fiber and different tricks to help you feel full longer. It is a plan that might help you lose weight, but doesn't seem to me like healthy eating. There are recipes for cake and all kinds of foods filled with artificial sugar, flours etc. The recipes in this book are few and far between. You will need to buy the cookbook as well in order to fully benefit from the plan. Overall I wasn't impressed with this book. There are many other diets to follow that are backed by science and are much healthier. This fad diet isn't going to cut it for many long term. I received a free copy of this book in exchange for my honest review.
