I'm not a carnivore but do think we should have/enjoy various animal proteins. I went without meat for couple of decades (re/the fat scare/healthy-hype drama) but feel better with minimal meat in my diet. What do the anti-meat people expect the diabetics to eat for protein? The ones I know have enough issues eating a minimum amount of carbs. Tofu has carbs (minimal) and some dairy, also, but many of us are allergic to dairy. Lentils, beans, nuts, have carbs. Carbs are great but some of us need a more balanced diet. I've tried to eliminate meat products but can't and I'm not diabetic.
It's like the brown rice scare -- we were told to eat brown rice and then couple of years ago to stay away from it - eat the white. The Okinawans live on it (and fish) - minimal fruit (can't remember how many veggies they consume) and are one of the Blue Zones of planet earth. I'm sure there's a way to obtain enough protein but I've tried to balance out healthy, wholegrain carbos, without meat protein sources, and have failed.
How does one live without BLTs and barbecue ribs once in awhile.
