One of the best books I've read and re-read many times. I find the information easy to read, and consumable in a single sitting. I have studied and perfected it on myself over the years, to attain my perfect body weight. I highly recommend this book especially if you are considering the HCG method of weight loss. I wouldn't start this kind of weight loss unless you fully understand all the idiosyncrasies of Dr. Simeons' entire Protocol.
