For ME, I need to eat something first thing in the morning or I continue to rise all day. Something good and fatty. Coffee with cream, broth with ghee, hard boiled egg with mayo. A few nuts or a piece of cheese. This shuts the liver down.
Even during the day a piece of celery or mushroom dipped in a mayo sauce lowered me. I needed just enough to elicit an insulin response. So no carbs for me especially in the morning but that’s not saying it won’t work for you.
I also always found a slow to moderate 15-20 min after meals brought me right down. Anything strenuous that raises cortisol or adrenaline sent me right up.
