For example if you’re intermittent fasting or water fasting, and the hunger comes and goes in waves as opposed to just getting hungrier and hungrier by each passing hour. How come? I do intermittent fasting and my periods of hunger are brief. You’d think the longer I go without eating, the worse my hunger would get but instead, I just get these brief periods of hunger and they eventually disappear, as if I had already eaten.
In:
The hunger sensation you feel is not a result of your stomach being empty, nor a requirement for food.
The sensation is caused by the hormone ghrelin. It is produced to stimulate appetite to encourage you to eat. Sights and smells can stimulate ghrelin production, but also learned behaviour in regard to food timing. This is why you will feel hungry at breakfast time, then the sensation goes (regardless whether you’ve eaten or not) only to come back again at lunch time.
