Hunger (physiology)
Hunger is a sensation that motivates the consumption of food. The sensation of hunger typically manifests after only a few hours without eating and is generally considered to be unpleasant. Satiety occurs between 5 and 20 minutes after eating.[1] There are several theories about how the feeling of hunger arises.[2] The desire to eat food, or appetite, is another sensation experienced with regard to eating.[3]
The term hunger is also the most commonly used in social science and policy discussions to describe the condition of people who suffer from a chronic lack of sufficient food and constantly or frequently experience the sensation of hunger, and can lead to malnutrition. A healthy, well-nourished individual can survive for weeks without food intake (see fasting), with claims ranging from three to ten weeks.[4]
Satiety is the opposite of hunger; it is the sensation of feeling full.[5]

"People can last a few days without water depending on the environment in which they find themselves and whether [they are] injured or not," says Jeremy Powell-Tuck, professor of clinical nutrition at Barts and the London Queen Mary school of medicine, who supervised Blaine's recovery.
