Never Hungry

There’s also a reason for you to not feel hungry after not eating for a long time. If you haven't eaten in a long time, your body doesn't relax, it instead increases stress hormones, i.e., adrenaline and cortisol, which induce the metabolism of energy stores (fat tissues, glycogen) and helps mobilize you so that you can find food or fight for it. Once you eat, stress hormones decrease, blood flow to the intestines and visceral organs is restored, and you feel hungry again. This is why appetizers induce appetite.
