I eat Paleo too. Since mid-October. Never going back (well, that and I found out I actually have celiac disease). I follow it pretty closely, with a few exceptions for (very occasional) cheese, good red wine and 90% chocolate (can't eat anything else, I find 90% to be almost too sweet at this point). I eat a lot of pasture raised eggs, grass-fed meats, veggies and a few apples now and then (oh, and berries). On the days I eat too many carbs, I can definitely feel it. I also fast a lot - mostly on weekends. I have never felt better in my life. It's a bit more expensive this way but I feel like the money I invest in my health now will pay off later.

It's amazing how nutrition affects your health.
