Fiber has long been heralded as a source that encourages weight loss. Modern science has been able to prove this assumption through research that supports the theory. Take natural fiber in dietary supplemental form if you wish to add fiber to your diet or don't eat enough of the foods that contain it naturally.
Types of fibers :-
1- Insoluble fiber is found in bran, grains, and wheat, and does not dissolve in water.
2- The other type of fiber, which is more commonly used in supplements, is soluble fiber. This can dissolve in water and is found in natural sources like fruits and legumes.
Metabolism :-
Weight loss is stimulated by speeding the body's metabolism and burning more calories (energy) than you consume and store. Speeding the metabolism can be done in two ways to stimulate weight loss. One way is to exercise regularly using specific methods such as interval training to increase your resting metabolic rate. The other way involves when you eat (time intervals) and what you ingest as energy. Unless you speed up your metabolism, there is often no healthy way to lose weight. This is the premise behind fiber supplementation.
Effects :-
Bacteria in the intestine can't use insoluble fiber as energy, but the digestive system still works to try to break it down. Supplements that promise weight reduction include this fiber because it forces the body to waste energy trying to break it down. The "wasted" energy means your body will be burning calories even when you are not exercising, which can stimulate weight loss.
