I recently commented this from a post that inspired me. Thank you, 
There really aren't any pros to eating meat. It's just stimulation and pleasure, which will numb you from other simple and sweet pleasures of life. If you cannot liquefy it (the meat / flesh), you cannot bring much of it into your blood. Which means you do not assimilate it. Basically, you do not assimilate animal flesh. It's a waste. It's crap--literally :) Don't believe me? Try this...
First Eat Flesh
See how long you can thrive on eating only animal flesh. Since you're vegetarian, switch "flesh" and "animal flesh" with tofu or something to mock meat :D ONLY eat animal flesh, raw or cooked: do not add lemon, herbs, spices, salt, etc. Do not have a bun for a burger. Do not add butter...do not add anything. Eat the animal flesh just plain. I repeat: ONLY animal flesh! Do not drink juice, do not drink water. Eat flesh--not eggs or milk. Test your strength and stamina every other day. All sort of things will happen, but I'll highlight a couple that I have personally experienced:
- The best to happen is you will be highly stimulated--much like being in a "micro" fight or flight mode--this may take 1-3 days to really kick in majorly. You'll feel good and unlimited.
- The worst that will happen is you'll begin to get extremely fatigued--this may take 5-10 days until you feel major fatigue to the point where you cannot even run 50 yards. This happens to keto dieters all the time, and most will "carb up" on weekends to cope.
I really don't recommend you do this, because your life could be at risk.
Then Eat Juicy Fruits
Then see how long you can thrive on eating only oranges, or watermelon, or mangos, or persimmons (it is the season). Pick one juicy fruit, buy a LOT of it, and eat as many of the ripest fruits first. Only eat that fruit...no water. Test your strength and stamina every other day. All sorts of things will happen, but I'll highlight a couple that I have personally experienced:
- The best to happen is that you will feel well-hydrated, happy, highly energetic, sleeping better, youthful, and more connected with others.
- The worst that will happen is you'll have serious withdrawal symptoms from the drugs created from cooking foods--you'll realize that you were addicted! Of course, you'll be tempted to distract yourself from the addictions by saying, "Oh, my body is telling me that I really need some bread... I know my body!"
As for the latter, I completely recommend it. Eat only the fruit. It will not jeopardize your life.
This is, of course, an example. I hope it helps and makes sense! :)
