    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]

  3. Ingestive behaviors - Wikipedia

    en.wikipedia.org/wiki/Ingestive_behaviors

    Hunger is the result of a fall in blood glucose level or depriving cells of the ability to metabolize fatty acids—glucoprivation and lipoprivation, respectively, stimulate eating. [13] Detectors in the brain are only sensitive to glucoprivation; detectors in the liver are sensitive to both glucoprivation and lipoprivation outside the blood ...

    Primary drives are innate drives (e.g., thirst, hunger, and sex), whereas secondary drives are learned by conditioning (e.g., money). Doris Kraeling and Byron Campbell conducted experiments to determine if “reduction would be more effective as a reinforcer if the initial drive were low than if the initial drive were high.”

    One of the most significant developments in hunger research since the Cannon-Washburn experiment is the recognition of hunger's multifactorial nature. Modern studies have revealed a complex interplay of hormonal, neural, and metabolic factors that contribute to the sensation of hunger and the regulation of food intake.

    In 2007, Kurrasch et al. found that the ventromedial hypothalamus is a distinct morphological nucleus involved in terminating hunger, fear, thermoregulation, and sexual activity. [1] This nuclear region is involved in the recognition of the feeling of fullness.

  8. Set point theory - Wikipedia

    en.wikipedia.org/wiki/Set_point_theory

    In humans, when calories are restricted because of war, famine, or diet, lost weight is typically regained quickly, including for obese patients. [2] In the Minnesota Starvation Experiment, after human subjects were fed a near-starvation diet for a period, losing 66% of their initial fat mass, and later allowed to eat freely, they reattained and even surpassed their original fat levels ...

  9. Hunger - Wikipedia

    en.wikipedia.org/wiki/Hunger

    For hunger relief actors operating at the global or regional level, an increasingly commonly used metric for food insecurity is the IPC scale. [7] [6] [5] Acute hunger is typically used to denote famine like hunger, though the phrase lacks a widely accepted formal definition. In the context of hunger relief, people experiencing 'acute hunger ...
