Glucomannan has been used for centuries in traditional Japanese cooking. It's often found as a thickening or gelling agent. It's this quality that helps make it a great component in weight loss. The best part is there are no harsh chemicals. This natural root helps with weight loss without the side affects experienced with other weight loss medications.Glucomannan is a dietary fiber that dissolves in water and comes from the root of the Konjac plant. It works in a similar way to other water-soluble fibers. When consumed, glucommannan often acts like a sponge by reducing the absorption of carbohydrates and cholesterol, which can help support weight loss. It is able to attach itself to bile acids in the gastrointestinal system and move them out of the body in the form of excrement. This makes the body convert other cholesterol into bile acids, which can promote lower cholesterol and help fight the amount of other fats in the blood. Do not use glucomannan if pregnant or breast feeding.
