Query: This makes sense and it works

This is the first book on dieting that I have actually ever read past the third page. I read it from cover to cover in one sitting. Not only does the information make perfect sense, it works. I went from a size 10 to a size 4 in three months and I even cheated a little. I had started reading other information on low-carb diets, but most of it was so strict, I don't know how anyone with a family could stick to them. I am a true believer in this balanced way of low-carb eating. I have purchased about 10 of these books just to give out to friends. If you are serious about changing your eating habits permanently and maintaining your desired weight, this is a perfect place to start.
