The use of glucomannan did not appear to significantly alter any other study endpoints .
Pediatric patients , patients receiving dietary modification , and patients with impaired glucose metabolism did not benefit from glucomannan to the same degree .
Glucomannan appears to beneficially affect total cholesterol , LDL cholesterol , triglycerides , body weight , and FBG , but not HDL cholesterol or BP
BACKGROUND Several clinical trials have investigated the impact of glucomannan on plasma lipids , body weight , fasting blood glucose ( FBG ) , and blood pressure ( BP ) , but have yielded conflicting results and had only modest sample sizes .
OBJECTIVE The objective was to perform a meta- analysis of r and omized controlled trials of glucomannan to better characterize its impact on plasma lipids , FBG , body weight , and BP .
Effect of glucomannan on obese patients: a clinical study.
An eight-week double-blind trial was conducted to test purified glucomannan fiber as a food supplement in 20 obese subjects .  Glucomannan fiber ( from konjac root ) or placebo was given in 1-g doses ( two 500 mg capsules ) with 8 oz water , 1 h prior to each of three meals per d. Subjects were instructed not to change their eating or exercise patterns . Results showed a significant mean weight loss ( 5.5 lbs ) using glucomannan over an eight-week period . Serum cholesterol and low-density lipoprotein cholesterol were significantly reduced ( 21.7 and 15.0 mg/dl respectively ) in the glucomannan treated group . No adverse reactions to glucomannan were reported
