"CD 4 info is available online"
This book is very helpful. Dr. Hyman does a good job of showing why we might be working against ourselves in regard to staying healthy and trim, and how to remedy it. The information on CD 4 is available on the product summary page for this book on audible.com. Just click the product summary tab above, and look at the very bottom for the "extras" link. There is similar information available at ultrametabolism.com/guide, though the extras link is probably better.
