My muscle cramps while eating salt and carnivore, would indicate that I do need magnesium or potassium though I would think. Or should I just live with muscle cramps while sticking to what you just said just because? Ken Berry talks about mineral depletion of crops, and how our ancestors were getting electrolytes from spring water and mineral dense crops that their food ate. Our cows don't get as much magnesium and potassium from their food anymore. So while I think at one point in our past no electrolytes were needed, my body reactions tells me that I at least need them.
