CONCLUSIONS In otherwise healthy overweight or obese adults , there is some evidence that in the short term GM may help to reduce BW , but not BMI .
OBJECTIVE Glucomannan ( GM ) , a soluble fiber derived from the plant Amorphophallus konjac , is marketed as being helpful in reducing body weight .
However , the data supporting this cl aim are scarce .
The aim of this review was to systematic ally evaluate the effects of GM on body weight ( BW ) and body mass index ( BMI ) in otherwise healthy obese or overweight children and adults .
Experiences with three different fiber supplements in weight reduction.
BACKGROUND Fiber supplements added to a caloric diet have additional effects on weight reduction in overweight subjects . The aim of this study was to compare the effect of various commercial fiber supplements ( glucomannan , guar gum and alginate ) on weight reduction in healthy overweight subjects . MATERIAL / METHODS One hundred and seventy six men and women were included to receive either active fiber substance or placebo in r and omized placebo-controlled studies . The fiber supplements consisted of the viscous fibers glucomannan ( Chrombalance ) , glucomannan and guar gum ( Appe-Trim ) and glucomannan , guar gum and alginat ( Glucosahl ) . RESULTS All fiber supplements plus a balanced 1200 kcal diet induced significantly weight reduction more than placebo and diet alone , during a five week observation period . However , there were no significant differences between the different fibers in their ability to induce weight reduction , which was approximately 0.8 kg/week ( 3.8 + /- 0.9 , 4.4 + /- 2.0 , 4.1 + /- 0.6 in the Chrombalance , Appe-Trim and Glucosahl group , respectively ) . CONCLUSIONS Glucomannan induced body weight reduction in healthy overweight subjects , whereas the addition of guar gum and alginate did not seem to cause additional loss of weight
