I first used the previous version of this book 2 years ago and lost nearly a stone in 2 weeks (just to clarify I was about a 12 stone with an ideal weight of 10 and half stone). Now I can hear you thinking that it is clearly a fad diet or unbearable strict, and well, you'd be wrong.
Admittedly the first week is tough when you start cutting out all the toxic crap, but the second week was far easier. After that it is really easy to stick to. You can enjoy really great food and the occasional blow out.
The diet itself is simple, no processed food, and the trick to slimming down is the quick and easy stretching routine in the morning and before bed.
So as far as the concept of lean and clean lifestyle goes I would thoroughly recommend it. The thought process and logic that it takes you through really struck a cord with me.
Now I had originally borrowed the book the previous time, and as the weight had crept back up again, I decided to repurchase the book, but could only lay my hands on this version. Now I decided to get the kindle version and unfortunately this book does not work as a kindle book as it makes it very hard to se what is going on and the pictures mess up the format of the pages. My advice buy a hard copy.
Overall I'd give the content 5 stars but the kindle version 2 stars but still 4 overall.
