Konjac is known for its ability to occupy a large volume by absorbing water, especially in the stomach. This allows to have a feeling of satiety quickly. Konjac is a plant native to Asia, used both in cooking and in traditional medicine. Its root is known for its high content of glucomannan, a very soluble fiber. This fiber has a high viscosity and a high water holding capacity. It will swell in the stomach and moderates the appetite, which limits cravings, thus limiting excessive caloric intake. It is a slimming ally of choice, particularly rich in glucomannan. It contains 80% glucomannan, for optimal action.
