That was not true for me. I tried lowering my salt intake on carnivore and I think that caused some of the problems that I had during my carnivore trial.
I’m restarting another carnivore trial for some of my joint problems returned, but this time I am keeping up my salt. I need to add an extra 1.5-2 teaspoons a day, not including what is in my food or I get muscle cramps, heart palpitations, and my blood pressure drops too low. It’s possible the extra need for me is related to sodium loss due to exercise and middle-aged hot flashes, but for now it is what my body requires. I really do find it interesting how different we all are.
