Changing your mind based on evidence and experiences are different. I am confident that if I eat a meal, my hunger will decrease. Does that mean I should update my hunger downward now without eating?

One's hunger isn't really an idea of the mind that one can change, yeah? I'd say that "changing your mind" (at least regarding particular ideas and beliefs) is different than "changing a body's immediate reaction to a physical state" (like lacking nourishment: hunger).
