Satiety

Definition

Satiety is the feeling of fullness and the suppression of hunger after eating, which helps to control how much and when we eat.

Scientific / Technical Definition

Satiety refers to the physiological and psychological mechanisms that signal to the brain when enough food has been consumed to meet energy needs. It involves a complex interplay of hormones such as leptin and ghrelin, nutrient signals from the digestive tract, and neural signals from the gastrointestinal system that collectively help regulate energy balance and prevent overeating.
