Dietary Fiber Promotes Weight Control

Promotes Weight Control

Dietary Fiber - Promotes Weight Control
High-fiber diets decrease appetite, reduce food intake and help prevent weight gain. Dietary fiber decreases the energy density of foods, which results in reduced caloric intake and hunger. Also, high-fiber foods take longer to chew, which helps satisfy hunger and reduces meal size. A study from the Netherlands found that more viscous fibers, such as pectin, beta-glucans and guar gum, decreased appetite more than less viscous fibers, such as wheat, oat and corn fiber. However, high-fiber diets only decreased energy intake by 2.6 percent compared to diets lower in fiber. Increasing dietary fiber promotes weight control, but it is no panacea for preventing obesity.
