How does lettuce primarily contribute to calorie management and satiety?
Answer
By providing significant volume and bulk due to high water content without substantial calories
Lettuce excels in calorie management primarily because of its exceptionally low caloric profile, which is a direct consequence of its high water volume and correspondingly low levels of carbohydrates and fats. This characteristic enables 'volume eating,' where large physical quantities of food can be consumed for minimal energy intake. Eating a large bowl of lettuce, such as Romaine, which might register fewer than twenty calories, physically fills the stomach. This physical bulk signals satiety, or the feeling of fullness, to the brain, making it a staple for dietary planning focused on energy restriction without feeling deprived of food volume.
