Fiber plays a crucial role in promoting satiety and aiding weight management by slowing digestion and prolonging the feeling of fullness. Foods rich in fiber take longer to break down, which helps stabilize blood sugar levels and curb hunger. This can lead to reduced calorie intake overall, making it easier to maintain a healthy weight. Additionally, high-fiber diets are associated with numerous health benefits, such as improved digestion and lower risks of chronic diseases, contributing to holistic well-being.
