Fiber aids in weight management primarily by promoting a sense of satiation and reducing overall caloric intake. It increases the bulk and water content of food in the stomach, leading to a feeling of fullness that can prevent overeating. Moreover, high-fiber foods tend to be lower in calories and more nutrient-dense, which can encourage healthier eating habits. Fiber also supports digestive health, regulating blood sugar levels and preventing spikes that can lead to hunger. Incorporating adequate dietary fiber into the diet is a key strategy for successful weight control.
