There are definitely some advantages to being vegetarian. For one you become more alert. Meat tends to make you sluggish...I would like to cite an example here. Look at the king of the jungle, the lion. The lion eats a deer or zebra and then remains inactive for days unhtil he becomes hungry again. One reason is that meat takes more time to get digested. And now look at a cow. The cow eats grass and keeps moving slowly & eating & moving. Green leafy stuff digests faster.
You also lose weight...since the fat content in veggies is much less almost nil ( hey I ain't sure about the exact content of fat, but do know it's marginal)!!!
