I have done his protocol with great success in the past. Not only did I lose weight I felt great. The first time in a long time I was off meds. It may sound strange, but even colors looked more vivid. I have done the 10 day twice, the 5 and 15 day once each. For some reason this last time I did not lose weight.. But I felt great regardless. We still have at least one green juice a day and try to add on a yellow or orange drink too.
