Our kidneys do just fine, if not already damaged from a completely different reason.
“Our kidneys do just fine, if not already damaged from a completely different reason.”
I haven’t specifically studied it, but there is quite a bit out there regarding high protein being tough on kidneys - but probably not to the point of threatening failure (at least in otherwise healthy people).
But, I would also guess if you get it completely wrong - very high protein, low water intake, you may start to develop problems. But then again, Keto doesn’t recommend that, and neither does anyone else here...so I don’t even know why it’s being discussed.
