"The Secret Is In The Diet" was written by Dr. Waychoff for the sole purpose of dissing all the "Fad Diets" that people have dreamed up over the years. Many of these"Fad Diets" do a great deal of harm. if people will just stay away from the "NO-NO" foods and drink pure clean water, people would be much heathier and have fewer problems. This book contains the "Secret" to the RBTI program which is the list of "no" foods. If you eat these "no" foods you will never have a healing equation under the RBTI. If you do nothing but quit eating the "no" foods you will improve your health. This book contains the list of those "no' foods and if nothing else you should have this list.
