The first night after starting this diet I found myself eating a juicy half pound hamburger without the bread, a sweet potato with butter, a small salad with fresh lemons squeezed on top and some sparkling water. Life could be a lot worse!!!! This book was written by 2 Harvard educated scientists. It is thoroughly researched and made a ton of sense to me. I've dieted a lot in my life. I always lost weight and always gained it back. That's a pretty frustrating way to live. The weight gain and loss roller coaster is awful. Over the last 20 years I've tried Atkins, Paleo Diet, Zone Diet, Weight Watchers, Nutrisystem, South Beach Diet, Mediterranean Diet, Blood type Diet etc etc etc....They all work and they all have flaws which ultimately caused me to stray from them for one reason or another. As an example Nutrisystem is convenient but I don't want to eat that food forever. Atkins and Paleo cut out major food groups PERMANENTLY! They are way too extreme for me. Zone Diet was too much work. Weight watchers with the points was too time consuming. South Beach Diet was a nice fad but I got tired of that also. Anyway, without dragging on too much longer I want to say that the best part of the Perfect Health Diet is its SIMPLICITY! This way of eating doesn't require much thought, planning, or effort. The authors give you a list of foods to eat without asking you to eliminate carbs, fatty foods, meat or dairy. I was taught what carbs to eat and avoid and in what portions. I learned what fatty foods to eat and how often to eat them. I learned about about protein and was taught the right amounts of protein to eat. Most importantly i never feel hungry on the Perfect Health Diet! This diet WILL reduce your food cravings. You are fed well. You eat a lot of fatty foods and still lose weight. You can have dairy in the form of yogurt. You can have starches. You eat fruits and veggies along with lots of eggs, meat, and some fish. Basically you feel healthy because your body gets everything it NEEDS to make you feel GOOD! This diet is the only one I've tried that eliminates food cravings and hunger. I'd give this book 10 stars if I could
