High protein diets can trash a person's kidneys.

I've read that each kidney has a seven fold overcapacity for what people need. So if the kidneys are damaged something majorly bad had to have happened.

Kidneys are also involved in blood production along with bones.

Carnivore or keto is high fat diet. It's not high protein https://www.thecarnivoredietcoach.com/carnivore-foods.html
