It is silly to review a diet book unless you do the diet. If I ever attempt this diet I will come back and rereview this book. It is a modified Atkins diet with the modifications established to make it more enjoyable, easier to follow and more sustainable. I hope that it works because the best reviews come from those that were succesful and the poor reviews seem to come from those that consider themselves vegetarians or violated by diet soda consumption. This is a terribly biased book review - in fact, it isn't really a book review at all because I am too upset that the diet is useless for me and so I can't even think about whether it's well-written or whether it sets out to do what it says it's going to, or any of that.The reason I'm upset is because this diet was highly recommended by 2 women I know who are on the diet as part of workplace initiative, and I could see myself that they have both lost a lot of weight. I could do with losing a lot of weight, so I borrowed this book from the library. On its cover it says, "5 million French people can't be wrong" and I wail loudly, "What about the however-many-there-are-of-French-vegetarians?!" My problem, I know. My choice to be vegetarian. My problem if I can't stand the thought of eating nothing but eggs and non-fat cheese for 10 days in a row. Obviously a protein-only diet is not going to work for me. I'm fated to be fat.So my one-star rating is based on the fact that there's nothing personally in it of use to me. Aside from that, it's what I expected - a whole lot of words around the basic facts. Even if I wasn't a vegetarian I'd get annoyed with that. I want the facts - what to do and how to do it - and then I want to find the background information easily without having to read several chapters of chatty book. I guess you can't really expect anything else - the author would never make any money out of the book if it didn't pretend to be something that people wanted to read.
