Informative. Some of the explanations are a little technical, but there is a lot of information here for such a short book. The idea is to eat healthier, not diet and to not eat so much over-processed food. I was afraid it would be all nuts and berries, but she's not even a vegetarian. I liked the parts about not feeling guilty over what you eat and to concentrate one small change at a time. The idea that fat is essential and triggers feelings of fullness explains why it can be so hard not to over-eat on a low-fat diet. One of her major points is that if you were eating better food, your body would be happier and much less likely to over-eat. I really wanted more recipes, there were only 38 included. There is a long list of references in the back of the book, but no index. A full list of all recipes is in the table of contents.I won this through the goodreads first reads program.
