Hi you two,
I am also doing low-carb and am a vegetarian (was vegan for 6 mos. recently... will go back and forth, I'm thinking). I've been doing low-carb for about two months now and it's been great. I track everything on myfitnesspal.com. Terrible name for a site, but it works well... pretty easy to track stuff. A big difference for me here is that I have MS. Was diagnosed just about a month ago. There is a ton of info out there on treating MS with diet, and though it's not specifically low-carb, it is very veg oriented and adapts well. There are a couple MS diets and diet books.. most of what I'm reading is like a modified Primal Diet for veggies. Pretty interesting. A couple sites I find helpful are the Nerd Fitness site (again, lukewarm on the name, though it's kind of funny) and Mark's Apple a Day site.
Nice to meet you folks.
