I hear a lot of people on the carnivore diet are starting to include more carbs into their diet. As for eating organs, I agree, you get more out of it than simply the meat of the animal, but organs are not part of the new federal nutritional guidelines. And I can start smoking, do it for six months and not feel much issues.
Also, WRT to eating meat, I think there are a lot of issues in the same way there are issues with eating plant foods, i.e. due to the unhealthy/unnatural conditions. That's why I'm a big proponent in Regenerative Ranching/Farming. Not at all the same as the USDA run program of Organic Foods, nor is it the same as many types of "Grass Fed" beef.
Simple fact is, we are omnivores. I think all these diets of Carnivore, Fruitarian, etc.,,, Vegan is more about ideology, than rational thought.
