This book presents, in a fun and easy to read format, how your body functions and processes food. I found that portion of the book to be very interesting and informative; however, to follow the suggested diet which is very constricting, and would mean, in most cases, that one empty their entire kitchen, and refrigerator of all food, spices, drinks, etc. currently residing there, and replenish with the very specific, earthy items listed in the book is crazy.While I understand a change in eating habits is needed to become healthier, I found this diet to be extreme, and would eventually set folks up to fail because it is so way out there.I will keep the book as a reference to the processing of food through the body and will definitely not even attempt to follow the recommended diet.
