Query: I found this easy to do and it worked!

This is a very simple little book and it brings results! It has not been hard to stay on and I eat an assortment of wonderful foods. To me, it's been very much like like normal eating. My son tried it and lost easily, too! I think this book is worth it for the receipes alone, and is a great addition to any low carb library.
