hungry...

Hunger is a feeling experienced when one has a need (not desire, that is appetite) to eat. Satiety is the absence of hunger.

The often unpleasant feeling of hunger originates from the hypothalamus releasing hormones that target receptors in the liver.

Although a healthy, well-nourished individual can survive for weeks without food intake, the sensation of hunger typically manifests after only a few hours of without eating and is generally considered to be quite unpleasant.

The sensation of hunger can usually be alleviated by consumption of food.

Hunger is also the most commonly used term to describe the social condition of people who suffer from a chronic lack of sufficient food and constantly or frequently experience the physical sensation of hunger.
