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" ?
