Sorry can't help more
I would be curious to know what you're eating exactly. I've dabbled in Paleo and have done a lot of research on Zone (I have to buy a scale still, so have yet to start). I've heard the best success is when you incorporate them together. If you haven't done so yet, I would suggest at least reading about Paleo or Primal and see if it'd something that would be a good idea for you.
Sorry I can't be more help but I noticed there were no other replies so I figured a little something would be better than nothing.
