To Meat or not to Eat...Meat

I attended a wedding of a close cousin this weekend and something was brought to my attention. There were a couple women there that were vegetarians. Now, when I was younger, I was somewhat of a vegetarian. Somewhat meaning we ate fish and chicken, but no red meat. Now what I noticed or rather what was brought to mind this weekend is that everyone I know that is a vegetarian is really skinny. And very healthy. Now I know this isn't the post PC reason to become a vegetarian, but in my mind at this moment, vegetarian = skinny, which in turn makes me want to become a vegetarian so that I can = skinny. So the question is, to meat or not to eat meat?
