I’m too new to offer an educated response, but I do know it is very important to keep hydrated. It also seems to speed up fat burning. I read this, which was interesting:
Burning fat costs one water molecule per two carbon atoms in a fatty acid molecule. The repeated process of pulling two carbons at a time from fatty acids is called “beta oxidation” or the “fatty acid spiral.”
Carbohydrates are the opposite. “Hydrate” is in the name so they bring a little of their own water to the party, about one water molecule per glucose molecule as they’re burned. Burning carbs, fats, or proteins eventually gives back water at the very end of the process, but burning fat costs more water during the process compared to carbs, and more overall.
But yes … the whole Ketostix thing is weird. I think I am finally at a place where I am just pleased I am in Ketosis, so they were helpful to know that, at least.
