Actually, there are 4 things that will cause cramps if you're lacking in them. Calcium, potassium, magnesium, and sodium. Since there is lots of potassium in meat, I doubt that's your problem. Are you taking any supplements?
As for the ketone thing, don't sweat it over the color of the stick. The change in darkness could be nothing more than your level of hydration.
