Satiated

Satiated is an adjective meaning filled to satisfaction; having one's appetite or desire satisfied, often to the point of not wanting more. In nutrition and physiology, the term is closely related to satiety, the state that reduces hunger after eating. Satiated describes a person who has recently eaten enough to feel full and content, with the sense that further intake is unnecessary in the short term.

In scientific contexts, satiation is the process that signals meal termination, while satiety refers to the longer-lasting feeling of fullness that suppresses subsequent hunger. These processes involve mechanical signals from the stomach and intestines, hormonal signals such as cholecystokinin, peptide YY, and leptin, and neural pathways in the hypothalamus. Food composition, fiber, protein, and energy density influence how quickly a person becomes satiated and how long they remain satiated.

Etymology: satiate comes from the Latin satiare, from satis meaning enough; the English form 'satiated' arose in early modern English. The related nouns satiety and satiation refer to the state of being full and to the process by which fullness is achieved, respectively. The terms are closely related but used in slightly different ways in nutrition and everyday language.
