I have read this book and tried this diet and found it works for me. I am a sugaraholic and by eating high fiber whole grain plant based foods I have found my weight and size drops, my cravings disappear, I feel more energetic, AND I can literally gorge on these type foods and not gain weight, feel bloated or drowsy later. For example, the other day I stuffed myself on thawed frozen blueberries and a type of artisan bread called Muslix bread. These high fiber whole foods satisfies me in the exact way a candy bar satisfies me, but without feeling unhealthy and sleepy after, and I feel energetic, alert, and am losing weight in spite of eating this way. There are foods that taste great and are unhealthy and fattening, and there are foods that taste great and make you healthy. This book is all about finding good health and a healthy weight and still enjoying food while overcoming cravings. The research Dr Barnard has done using Narcan to block endorphins causing subjects to lose their cravings for certain foods like meat and sugar is especially revealing.
