Is intermittent fasting safe for your adrenal glands?

It's a normal process and function for cortisol to counter a low blood sugar level. So when you do intermittent fasting, your blood sugars drop and cortisol, the adrenal hormone kicks in to prevent this. It's a normal function for cortisol to do this just as cortisol also increases your WBCs and inflammation during infection and injury. It's not that these things stress the adrenal, it's just a part of the normal process of the purpose of cortisol. You may need to fix your insulin resistance AS WELL AS your adrenal separately.
