The role of dietary fiber in weight-loss


Appetite control, or more likely the lack of it, is one of the most important problems that cause people to gain weight. The same issue is present when dieting as it usually involves caloric restriction. Having a strong will is still a good thing when you’re trying to eat healthy and lose or maintain your weight but there are ways to control your hunger by eating the right foods and minimize the risk of failed diets and/or food abuse.

Dietary fiber is the indigestible part of edible plants that can have a large number of health benefits when consumed regularly. While fiber doesn’t provide calories and nutrients, it travels through the digestive system slowing down the movement of the food. This reduces the hunger feeling and keeps us satisfied for a longer time. Nevertheless, there are many other health benefits of dietary fiber including prevention of some diseases.

How does it work?

There are two types of dietary fiber: soluble fiber – turns into gases and active byproducts in the colon, through fermentation; insoluble fiber – this is the type of fiber that doesn’t get digested and it absorbs water as it travels through the digestive system, promoting stool regularity.

Fiber can be a very effective way of preventing or treating constipation as it can ease bowel movements, but in order to work at its full potential you must be properly hydrated.

Concerning weight-loss, fiber does more than give an increased feeling of satiety and reducing the appetite. Dietary fiber can also change how the body absorbs food derived nutrients and chemicals. It actually absorbs and carries out some of the fat and calories that we ingest. As a result, including fiber-rich foods in your diet can help you lose weight without feeling hungry all the time.

By regularly eating fiber-rich foods you will not only improve your digestion, but also reduce the risk of various health conditions such as heart disease, diabetes and obesity.
