About being nearly ZC, I second what Julie (aka InSearchOfAbs) said about the Dirty Carnivore site. They are people who embrace being a carnivore but don't get fanatical about it. (Unlike the Zeroing in on Health site where there are some serious wingnuts).
I have been eating nearly all my calories from animal products for quite a while now and I find the greatest thing about it is that it makes counting carb grams a non issue.
It really is interesting when you change your perception of veggies from being this indispensable thing without which health is not possible to being something that can enhance the flavor of the meal (the meat) or serve as a garnish or condiment but is not really that central to your eating.
After not eating much in the way of veggies for a while, my digestive system is the happiest it has ever been. And when I did a couple of high veggie days in a row (vegetarian friends visiting) I felt all plugged up and bloated. I still eat a salad if it comes with a dinner out or a friend has prepared it but my big salad bowl at home which used to be in daily use doesn't get much love these days.
