I highly recommend this book. I started reading the book 2 weeks before thanksgiving. By Jan 30, I am down 22 pounds and feel great. There is no complicated formula. Just eat 80-90% of your food from fresh veggie, fruit, beans, seeds and nuts. Start slow if you need to, including stay out of fast food restaurants, avoid processed foods and white flour product (yes, bagels too). The book provides some great tips for getting healthy by just eating the right foods.
