Apparently so. While our society may have evolved to provide us with endless opportunities to eat, our bodies are primarily concerned with keeping the well-oiled machine going. This means that we start to feel hungry once our stomach is empty. After a meal, our gastrointestinal tracts slowly empty by pushing food through the stomach and the small and large intestine. Specialized contractions called the migrating motor complex MMC sweep up undigested food, which is a process that takes around minutes.
The final phase of the MMC is regulated by a hormone called motilin. Motilin-controlled contractions cause the rumbling in our stomachs and coincide with hunger pangs in humans. Another hormone implicated in hunger control is ghrelin. In mice, ghrelin activates neurons called agouti-related peptide AgRP -expression neurons in the hypothalamus region of the brain, which tell us that we are hungry. These neurons are the control center for hunger.
When AgRP neurons are artificially switched on in mice, they gorge themselves on food. Here, we need to differentiate between homeostatic hunger, which is related purely to balancing our energy reserves short-term, and hedonic hunger, which makes use of opportunities to gather extra energy. Hedonic hunger is less well understood than homeostatic hunger. If we are full, we might take a rain check.
