On the issue of fat % of diet: 1. On fat % of megafauna (NeanderThin, Appendix B): "As well as being larger than animals found in temperate climate today, the Pleistocene megafauna were adapted to long winters of deep snow, having evolved the ability to store large amounts of body fat...." (so the protein/fat/carbohydrate % of pleistocene people may not be so clear cut) 2. If the current game meat fat % cited is really that low, then if you restrict yourself to that low a fat % then you would have to make up those calories by eating more carbs if you are going to maintain energy, right? So in some sense if you are a low-carber the fat % issue is moot. If pleistocene people were low-carb by necessity then it makes sense they must have found more fat.
