Query: A Poor Choice

This is certainly better than the more modern low-carb fad diets, but it's similar to them in that it's based on pseudoscience, annecdotal evidence, and general misunderstandings of how the body works. Haas has basically repackaged the Pritikin diet from the 70s and added some of his own mumbo jumbo. Unless you're an endurance athlete eating a huge volume of calories to keep up with your expenditures, you probably won't get enough protein from this diet.Do some real research, and follow the simple (and un-magical) recommendations of researchers who have done real peer-reviewed studies.As far as my own annecdotal evidence, my performance in cycling and alpine climbing improved immensely when I ditched the Haas plan and embraced a more traditional 60-25-15 diet designed for athletes.
