Even without getting into the differences about limiting meat fat % intake or that you don't have to limit fruits, one thing stands out that raises some skepticism of Cordain's book. In previous interviews/writings he states: "We have recently compiled ethnographic data from 181 world wide societies of hunter gatherers showing that the mean plant to animal subsistence ratio in terms of energy was 35% plant and 65% animal." e.g the http://www.dfhi.com/interviews/cordain.html interview - also found elsewhere. And then in The Paleo Diet, he changes the 65% above to 55%. Was he just "moderating" this figure to not appear too "radical" ? Philip Thrift http://www.geocities.com/PaleoFitness
