How does celery's physical structure contribute to promoting satiety for caloric management?

High water and fiber content promotes feeling fuller on fewer calories

Celery's effectiveness as a tool for managing caloric intake stems directly from its physical composition, specifically its very high water content combined with a substantial amount of dietary fiber. This dual presence promotes satiety, which is the feeling of being full or satisfied, allowing an individual to consume fewer calories overall. By incorporating a large volume of celery—which is low in energy—before or during a main meal, the physical bulk stretches the stomach and the fiber begins to slow digestion, naturally reducing the subsequent amount of food consumed. This physiological feedback loop, reinforced by the energy expenditure required to chew and process the fibrous material, serves as a practical, non-pharmacological method for supporting weight management goals.
