I agree by the way. Just from experience. But why?
Well meat has little liquad in it, it is very dense, hard to digest (break down) coupled with the idea of making its way through the intestinal maze, it is just a harder process.
Veggies and fruit are usually full of liquid, if they aren't cooked to death. Lots of fiber, and actually clean our intestines out through its journey.
Problem is making sure you get the right protein, via Hemp Seeds, and other non meat sources. Cause you still have to have a balanced diet.
Other issue is B12, it is generally said to only come from eating certain animal parts, as it is found in vegetation that is eaten, and then passed to us. However, we cook our food so much, and many animals we eat these days don't get to eat vegetation, an argument can be made it isn't a good source of B12 either.
B12, is so important to us, that if we run out of it, we lose our nervous system permanently. Brain damage etc... The good news is, typically we have about 3 years of supply in our liver of B12, so it is hard to run out, but many vegetarians do run out, because they believe they can get B12 from certain veggies, which is contested right now. It is believed certain mushrooms, and certain seafood (and sea vegetation) may be a source.
Anyway, that's just some of the stuff I have learned about changing my diet.
