The Ultimate Diet 2.0 represents both a very old and very new approach to the problems of dieting to low bodyfat percentages. It is old in that it builds upon an approach originally developed in the early 80’s by bodybuilding guru Dan Duchaine and researcher Michael Zumpano. It is new in that it applies the most cutting edge research to that plan, optimizing it to the greatest degree possible. The Ultimate Diet 2.0 is aimed at advanced dieters and athletes who want to move from ordinary to extraordinary. It will allow dieters to lose 1-1.5 lbs of fat per week with no muscle loss (some dieters gain muscle). It allows athletes to maintain or improve performance while losing bodyfat. It can also be used to gain muscle with minimal bodyfat gains.
