Query: The Ultimate Guide to a Thin Wallet

Dr. Phil is a disgrace to his profession. This book is just another way for a TV personality to make a buck. It's a way for Dr. McGraw to grab a piece of the billion dollar diet industry hoax...you think you know what it's like Dr. Phil to be really fat?...guess again. Your book has been written before many times and in many different versions by many different people. Maybe you just packaged it differently or perhaps on the laurels of your recent TV exposure you will sell a million copies!
