Jim,

I would be curious to see your bodyfat levels and how they change with switching from Atkins to Zone. Even though this system is very crude, will you please post your waist and wrist measurements now, and occasionally re-post updates. I switched off Atkins because I was not gaining enough muscle for me and went to a modified Zone (40% protein instead of 40% carbs with 30/30 for carbs/fat). This has worked very well for me but I have to admit that it is even harder to eat carbs while keeping them super low compared to just avoiding them. My impact carbs are still pretty low since alot of the carbs that I am eating are in my protein bars and they claim to be low carb. I dropped 10 lbs quickly on Atkins, but my bodyfat only budged a little bit and on the Zone, I have lost only 5lbs of weight, but bodyfat has dropped 4% and waist measurements have fallen 3 inches while my chest, back, thighs are getting bigger, more defined and stronger.
