I take it the vegetarian and vegan low carb forums here are no good for you?

I personally eat meat and fish and dairy (am in New Zealand and only relatively low carb) but can see the argument for less intensive meat farming. I'd probably be vegetarian if I lived in the US (don't trust their meat processing industry).
As for dairy, I personally love it, but supposedly 75% of the world's population are lactose intolerant???
