Maybe your ancestors were cold-weather adapted and your body is pre-disposed to hold onto weight in the winter? Works for me! LOL

I found this thread interesting, as an Anthro major (freshman, don't expect enlightenment!), the idea that we are evolved to eat a hunter/gatherer diet makes perfect sense to me. 10,000 year or so is very little time for our bodies to adapt to a completely different diet. We can survive on high-carb, but it's not what we function best on. That said, I'm not sure that I agree that the HG diet was completely grain or dairy free. I believe that there would have been some grain comsumption, not a complete dependence, but a regular consumption. Grain is very easy to store, and probably would have been stocked for the winter. As for dairy, this is a little more off the wall, but, when you kill a nursing animal, why waste? Most parts of an animal are eaten in HG cultures, I really can't imagine that milk would be an exception? Feel free to call me on this one! LOL
