Query: Not enough, too expensive for what you get.

A shame that more available food items aren't available in this LITTLE book. Shocked by the small size and content. However, the book has helped a bit, but DIET REVOLUTION has most of this material (of substance) and IS RECOMMENDED with 6 stars out of only 5 possible. Have lost 90 lbs and going for more. Thank you, Dr. Atkin... expand this book and I will appreciate paying for it.
