If we were not meant to eat meat, we would not have cutting teeth and digestive systems designed to break down said meats.

Vegetarians are not natural, so to speak.

A vegetarian would die of malnutrition if it were not for the heavy import of very specific foods which are key to the diet and otherwise not found in the vast majority of said vegetarian's habitat. Meanwhile, a meat eater such as myself can go outside, trap a squirrel, and eat lunch.

You can't even try and argue that people should not eat meat based on evolution, because it would not work in a natural setting. Thus, vegans and vegetarians are "wrong" about the vast majority of their arguments.

They claim you lose a ton of weight by going vegetarian - why do you think that is? Because you are effectively starving your body. You can lose just as much weight just as fast by eating less of everything. The problem with a vegetarian diet is that it is difficult to over eat, because plants have a ton less energy contained within them by comparison. Hell, lettuce is NEGATIVE calories. It requires more energy to digest than you obtain from the stuff.

TLDR:
Left to their own devices, most vegetarians would starve very quickly. A system of import/export bringing specific foodstuffs around the world is required in order to attempt to create a balanced diet. This could never work "in the wild" so to speak - At least, not for a human. How do you plan on getting that very specific nutrient from a very specific plant that is only found hundreds or thousands of miles away? Something readily available in meat.

When was the last time you ever heard of a whole culture being vegetarian? Never. Humans have always existed with a mixed diet.
