Let's say you significantly dropped carbohydrate, or got over your addiction to sugar -- and by this I don't necessarily mean an Atkins induction, but just your transition to paleo. It was difficult at first, but then you "broke through" to the other side: the grumpiness went away, the lethargy went away, and you started feeling great.
But did you then take it a step further and try out ZC or VLC, or a meat-only diet? Did you once again feel sluggish and grumpy ... and then you broke through again? Such that you felt hunky-dory even at this new level? Did you attain a new level of "flexibility" with your metabolism?
Or perhaps your transition to paleo and a reduced sugar/carbohydrate intake was painless. Did you stay at this level for a while, and then, upon experimenting with ZC/VLC, experience the lethargy, followed by a breakthrough?
What I'm looking for is people who have tried out two "levels" of paleo, and what their experiences were like. I'm wondering if those of us who have a really easy time transitioning to an LC paleo might eventually run into trouble if we try to go ZC/VLC. And maybe those of us who struggle with just getting to LC might have an easy time going ZC/VLC. Is it like the chicken pox, do you just have to struggle once? Or can there be a struggle at each level?
