I am in my third week of going Primal and am in it 100% (at least I think I am). No grains, beans, sugars, etc. and from the first day I felt a change in my body that took me a while before I could articulate what it felt like. For me it feels like a lifting of a weight (no pun intended) from the inside. Also, I find that I have no desire to "have to eat" like I did before. The only problem is that I lost 5-6 lbs the first week and seem to be stuck now. That being said I am in it for the long haul.
