I think it's mainly ketosis that helps. No amount of gut healing will allow me to stay in ketosis while eating potatoes. I appreciate you trying to be helpful but I completely lost interest in eating plants at this point. Meat tastes great.

Meat is great. As is raw diary. Eggs. Honey. Fruit. And even some rice and potatoes, for hard physical workers of sport and otherwise.
Like many carnivore advocates say: plants don't want to be eaten.
