So you're more or less a vegetarian. I can see the benefits, but the problem is that there's no CALORIES in it. Is it healthier? Probably. But there's other factors you need to take into consideration. Sure you can get protein from beans, nuts, and other stuff, but are you getting all 9 of the essential amino acids? That's the hardest part. Not to mention, while it is supposedly 'healthier' and 'easier' for your body to digest, that doesn't mean jack once you realize that the bioavailability of protein in beans, nuts, lentils, etc. is super low, especially when compared to that of say a eggs, bison, fish, poultry, whey, etc. If you have enough money and TIME to properly prepare each and every meal correctly AND BE ABLE TO EAT ENOUGH OF IT, then I honestly do say that it is better than eating meat (save for a fish diet. I think crustaceans, fish, pretty much any animal from the sea added to your diet will be much healthier than if you didn't. There's basically NO downside to eating sea animals when it comes to health purposes, not from what I've researched anyway). The only thing that bothers me about this is that if you are able to do this adequately to where you do see NOTICEABLE improvements in your health, then I'd question why you don't just eat organic, free-range grass fed bison instead of regular beef, and organic free-range turkey instead of regular chicken as well. Both of those will minimize any kind of negative side effects regular meat will cause, while greatly enhancing all the positive effects. As for pig products (pork, salami, bacon, ham, sausage, etc.) don't even eat those regardless. Their genetic coding is too similar to humans which is why your body has an extremely difficult time digesting it (it basically just drags the meat to the sides of your torso and hips). Thats why you feel it just kinda sitting their in your stomach.
Personally, I can't quite do what you're doing. I need to have something heavy in my stomach to fill me up, plus eating only veggies is hard because I have an extremely sensitive stomach; eating them raw or even steamed sometimes causes some very strange feelings in my stomach like it is hard to digest. That would explain why I hate most plant foods raw/uncooked. It's hard on my stomach for some reason.
Basically, if you can, do it. All the information I told you is based on the assumption that you are lifting weights seriously, at least regarding the bison/turkey/no-pork part. If you don't really lift or exercise hard, screw it. Don't eat meat at all because it doesn't really have any positive impact on you to begin with.
