Yes, it is. That is the exact version of the Clinic Diet that has been used for years, with the correct amounts of limited foods and all the other extra guidelines the Taubes/DietDoctor copy is missing. It is what I was given in Feb 2011 and is exactly what was in the Purple booklet that is no longer in print. There have been other versions on-line, and will be some newer plans in an upcoming book, but this is a good one to start.
