This is the most important book I have read in recent memory. If you are someone who has tried diets and not had lasting success this is the book you want to read. You will understand how the food pyramid was developed, why we have believed carbs are good and fats are bad for our health, why weight loss diets fail (pick a diet, any diet), and most of all what to do about it. You will understand what to do to change the outcome of your diet. I highly recommend this book.
