The slimming function of konjac is entirely because it contains a magical ingredient-glucomannan, commonly known as magic element, or KGM for short. Magic element is a kind of natural edible cellulose, which has many characteristics such as hydrophilicity, gelation, antibacterial, cohesiveness, edibility, low calorific value and so on. The polysaccharide contained in the magic element itself will not be decomposed by the human body and is a low-calorie food; Magic elements have strong water absorption capacity, and the water absorption and expansion can reach 80- 100 times. Therefore, people will not feel hungry after eating magic elements, which will reduce high nutrition such as fat and sugar and limit the source of heat. This is one reason why magic elements lose weight.
At the same time, magic element is the most viscous dietary fiber, which can delay the gastric emptying time, form a barrier on the intestinal surface and prevent the absorption and diffusion of sugar and fat. The absorption of sugar and fat is mainly carried out in the intestine. The longer food stays in the stomach, the shorter it stays in the intestine, the less sugar and fat it absorbs, and the less calories it consumes, which is more conducive to weight loss.
