Diet Accelerate losing weight with konjac tubers

The Konjak tuber should tumble the pounds

Regular konjac use may help you lose weight. Of course, this does not mean the alcoholic namesake Cognac, but the konjac tuber of the devil's tongue (Amorphophallus konjac), which has been used in Asia for 3000 years. Responsible for the slimming effect is the active substance glucomannan contained in the tuber, which achieves a saturation effect due to its enormous swelling capacity.

In Germany, the konjac tuber is rather unknown - in Asia, for example, in Japan, it has been on the table for 3000 years. The root can reach up to 25 centimeters in diameter and is often processed into Konjakmehl from which, for example, noodles can be produced.

The carbohydrate-free alternative to potato?

In appearance and consistency, the Konjak tuber is best compared to the potato. It does not contain human-utilizable protein or carbohydrates. But it is very rich in water-soluble fiber, which can be significantly better utilized by the digestive tract.

How does Glucomannan affect the body??

The konjac tuber contains the active ingredient glucomannan. This creates a strong satiating effect in the body, because it can swell on contact with water to 50 times the size. The stomach and intestinal tract react to the swollen fiber and give a saturated feeling.

No miracle cure, but a good help

Stiftung Warentest tested glucomannan weight loss agents for their effectiveness. In fact, the satiating effect can help you lose weight. Especially at the beginning of a diet such a cravings can be avoided and facilitate the conversion. However, one should expect no miracles, as the body gets used to the effect. Glucomannan is more likely to be considered as a tool to switch to a lower calorie diet.

Natural or as a capsule

Glucomannan is sold in pharmacies and drugstores mostly in the form of powders and capsules. Those who prefer a more natural intake can take glucomannans in the form of glass noodles (for example Shirataki). It is important that when taking capsules and powders not the specified amounts are exceeded and sufficient water is drunk, otherwise it can cause stomach problems, a bloated stomach or shortness of breath due to the violent swelling effect.

Are glucomannans harmful??

The European Food Safety Authority examined in a study in 2017 whether glucomannans are harmful to health. The Panel concluded that the use of Konjac is not harmful if the total intake from all sources remains below three grams of glucomannan per day. At the nutritional examination, some adults who took a dose of three grams of glucomannan a day for 12 weeks experienced mild discomfort such as diarrhea or constipation. Otherwise no side effects could be detected. (Vb)
