What is the function of fiber in weight management?

The function of fiber in weight management is particularly significant because it plays a crucial role in increasing satiety and consequently reducing overall calorie intake. Fiber is a type of carbohydrate that the body cannot digest, which means it passes through the digestive system largely intact. This characteristic allows fiber to contribute bulk to meals without adding calories, making it easier for individuals to feel full after eating.

When fiber is consumed, it absorbs water and expands in the stomach, which helps to create a feeling of fullness or satiety. This can lead to a natural reduction in the amount of food consumed during subsequent meals or snacks. Additionally, fiber can slow down the digestion and absorption of nutrients, which helps to maintain steady blood sugar levels and can prevent spikes in hunger.

In the context of weight management, including high-fiber foods, such as fruits, vegetables, whole grains, and legumes, in the diet can promote a healthier eating pattern that is not only lower in calories but also rich in nutrients. This can be particularly beneficial for individuals looking to lose weight or maintain a healthy weight over time.

The other options do not accurately reflect the benefits of fiber in weight management; fiber does not reduce hunger by providing no nutrients or lead to increased fat absorption, nor does it stimulate appetite
