Hi, I'm new to the list, and I thought to introduce myself briefly and ask several questions. My interest in paleodiets is immediate; I'm 6'0" (about 185cm) and 370 lbs (168kg). I have had considerable temporary success on the Stillman, Atkins, and other low-carb diets, but I always put it back on over a year or two. I lose slowly or not at all eating >25g of carbs. Two questions: what do the initials SAD stand for, in describing diets? And does anybody have experience with a reliable source of bison? I would eat it in preference to any other meats if I could get it relatively easily, but the local stores only sell small packets and the the producers I talked with charge so much for shipping that I would need to chip in with others and get 100 pounds or so to make it feasible. BTW, I'm located in the SF Bay Area, so local references, if you have any, are even more welcome. Mike
