Water-soluble fiber has multiple weight loss benefits. Studies suggest that high fiber intake diminishes appetite, increases feelings of fullness, and improves weight control. Now research reports that chitosan (a dietary fiber supplement) promotes weight loss.
The randomized, double-blind, placebo-controlled study, published in the Journal of the American College of Nutrition, investigated the effects of chitosan supplementation on body composition. Researchers at the University of Texas Health Science Center at San Antonio administered either 3 grams of chitosan daily with a self-monitored behavior modification program, a placebo daily with a self-monitored behavior modification program, or a program of their own choosing (control group), to 150 overweight adults for 60 days. The researchers obtained body composition measurements and blood samples from the participants. The participants self-reported daily activity, side effects and caloric intakes.
The researchers found that the chitosan group had an average weight loss of 2.8 pounds, the placebo group lost 0.6 pounds, and the control group gained 0.8 pounds. Findings also revealed that the chitosan group had a greater decrease in fat percentage and fat mass and a greater increase in body composition improvement index, than the placebo group,
"These data provide evidence for the efficacy of a chitosan compound to facilitate the depletion of excess body fat under free-living conditions with minimal loss of fat-free or lean body mass," the study authors conclude.
