..I have found this book invaluable, & feel much better for having followed the programme. It is not a weight loss book & nor do you 'change your diet every week'; its a guide to improving your overall health, by taking gradual, but significant steps to improve your nutrition & i've certainly seen the results. I am not one for fads, or complicated diets, & have discarded many such plans before even starting, because i just knew they were going to be impractical to stick to. Not so with this book. The author takes you through a series of questionnaires to help you decide which supplements you need to introduce, and each chapter explores ways of improving a specific area of your health. i felt embarrased at times reading it, as it pulls together a lot of common sense advice that I'd read but not bothered to put into practice. This plan helps to pull it all together in a common sense, practical way. BUY THIS BOOK! Your body will thank you for it!
