Overnight Colon and Liver Cleanse & Detox: Get Your Energy, Stamina and Mental Clarity Back in 11 days and Lose Weight Fast in the Process! Paperback – April 21, 2014

This book is about buying an expensive juice machine and living on the product for three weeks. If you are hardcore enough to do it, I don't see how it could fail. I'm not doing it. It isn't worth it to me but if you want it bad enough and have the money, go for it.
