Hunger

Originally uploaded by Jacinto Quesnel

Hunger is a feeling experienced when the glycogen level of the liver falls below a threshold, usually followed by a desire to eat. The usually unpleasant feeling originates in the hypothalamus and is released through receptors in the liver. Although an average nourished human can survive weeks without food intake , the sensation of hunger typically begins after several hours without eating.

Hunger can also be applied metaphorically to cravings of other sorts, e.g. “hungry for victory.”
