Re: Why did you go Vegetarian?
I never made a conscious choice to become vegetarian, I had a friend who was learning yoga from a group of Seiks, and he brought me some of their infomation on being vegetarian. I read it and though I was ignoring it, but it must have settled in my subconscious because shortly thereafter I found I couldn't make myself eat meat. I became vegetarian without even knowing why.
It took another 13 years until I became vegan (about 4 years ago), and vegan was a conscious choice. I have come to believe that animals are not ours to use, or to kill for fun or convenience. It was never hard to give up meat, for me to contemplate eating meat makes me feel ill, probably how most people would feel contemplating eating human flesh.
I've never considered going low-carb, but I have become more selective about the carbs I choose as I've learned more about nutrition.
