Effect of glucomannan on
obese patients: a clinical study.
Walsh DE, Yaghoubian V, Behforooz A.
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
