Re Na:K : Potassium Chloride is used as a salt substitute (which tastes surprisingly like regular salt). This makes it really easy to tweak the Na:K ratio (if it turns out to be important). OTOH, it’s some evidence that it’s not important, otherwise I’d expect someone to notice that people lose weight when they substitute it for table salt.

My current belief is that Potassium is only part of the answer, but it does have an important contribution. I will get to this more in future posts in the series. In the meantime some people did indeed try only adding KCl to their diet, and for some people, it did have an effect:
