Who said God wanted you to be anything? It's other people who want you to be this or that...
The arguments in favour of vegetarianism have more to do with health, food production, and moral questions than with anything God was demanding of anyone.
But diet has a lot to do with one's individual nature and one's surroundings. Meaning: if you live in a colder climate, you need to eat more meat and animal fat to generate sufficient internal heat. If you are cold...or short on yang energy, eating meat helps. If you are overloaded on yang energy, it's best to reduce meat intake. I've seen people who thrived on a lifelong vegetarian diet, and others who did not do so well on it. I've seen meat eaters who benefited from that diet, and those who suffered from it. Every case is unique, so there's no use making up rules about it. I've gone through periods when I ate a vegetarian diet...no problem. I've gone through periods when I didn't...again, no problem.
Dave-O's point about Buffalo wings is striking! Note that winged buffalo are no longer seen anywhere. This is clearly due to overconsumption of buffalo wings and something should be done about it. I do not want a world in which children grow up without ever having seen a buffalo fly over their yard.
