Query: Awesome book

I have worked both professionally and as an amateur trainer for over 10 years. This book is one of the best books on nutrition I have ever read. Unlike fad diets, it is based on science and offers a sensible food plan and regiment based on your body's requirements. After assessing your current metabolism the book shows you how to apply it using easy to understand food charts that you can learn very quickly and easily. Best yet, you can modify the food charts to fit your own likes and dislikes. No counting calories, no complicated menus and no starving yourself. If you adopt the authors advice you will soon find that you are incorporating a lifestyle which empowers you to maintain your weight and feel great doing it.
