I did the whole Robbin's "Living Health" program. It's not done by Tony Robbins, it's done by Dr. Robert Young. THere are definitely a lot of good things about the information in that course, and it's definitely better then the standard north american diet. However, after taking my Nutrition Studies I still think that Dr. Young is missing certain things.
I would not take everything he says as gospel, like anyone else I would do your own research and compare notes. If it helps, I did follow his diet plan for 3 weeks and lost 16lbs of fat and felt great. However, I gained it back afterwords because I went on a trip to Disneyland and fell off track as it's impossible to eat well while in Disneyland
