Have you heard of Pavlovs Dog, that started salivating when he rang a bell? Normally it's seen as an example of conditioning. But I think it's an illustration of something I noticed in my own life: That the primary cause of hunger feelings is expecting a treat. When I haven't eaten in a while and know food isn't coming, I don't really feel hungry, I just feel tired.
