Interpretive Summary: Konjac glucomannan is viscous soluble fiber derived from a tuber commonly cultivated in Asia. Viscous soluble fibers have been associated with decreased weight gain and appetite control. Different outcomes of dietary intervention studies of weight loss may be due to differences in the source and preparation of konjac glucomannan. This review discusses characteristics of konjac glucomannan important to its properties in the digestive tract.

Technical Abstract: It is safe and cost effective to reduce obesity and accompanying chronic disease via controlling appetite and energy balance. Konjac glucomannan (KGM), a soluble dietary fiber which would hydrate gradually and develop high viscosity in solution, has been demonstrated to have the abilities of delay gastric emptying, induce satiation related hormones, prolong satiety and reduce short-term appetite and hunger. The current review collected published information related to the role of KGM supplementation in regulation of appetite and obesity, focused on the association between micro and macro physicochemical structures of KGMs with their functions as appetite regulator. Collective clinical data of KGM on long-term metabolic energy surplus and weight loss were also provided.
