Just commenting because I've actually been flirting with the Paleolithic diet lately (more meat and fish, more veggies, fewer grains), but I can't quite bring myself to entirely cut out rice, bread, and pasta, just shift the ratio.

The GI diet you mention actually sounds a lot like what I've been trying to do as far as balancing it goes. What resources were you using? And why aren't you on the diet any longer, if you don't mind my asking? I'm genuinely curious.
