Chitosan aids fat loss
A study conducted at the University of Texas Health Science Center at San Antonio revealed that chitosan, a popular fiber supplement, was effective at reducing body weight and body fat in a double-blinded, placebo-controlled study. The findings were reported in the October, 2006 issue of the Journal of the American College of Nutrition.
Gilbert R Kaats, PhD, and colleagues randomized 150 overweight men and women to one of three groups. The treatment group received 3 grams chitosan per day to be consumed in combination with a self-monitored behavior modification program, a placebo group received a placebo plus the same behavior modification program, and a control group was directed to follow any program of their own choosing for 60 days. Body composition, bone density and blood chemistry were measured at the beginning of the study and at the end of the treatment period. Subjects who received chitosan or the placebo were asked to record the daily amounts of the supplement consumed, caloric intake, daily activity, and side effects.
At the study's conclusion, subjects who received chitosan experienced a significant reduction in weight and fat mass compared to the control group. While participants who used chitosan had an average weight loss of 2.8 pounds, those who received the placebo lost 0.6 pounds, and those in the control group gained 0.8 pounds. The chitosan group also had a greater reduction in fat percentage and fat mass than the placebo group, as well as an increase in body composition improvement index.
"These data provide evidence for the efficacy and safety of a chitosan compound to facilitate the depletion of excess body fat with minimal loss of fat-free or lean body mass under free-living conditions similar to conditions under which these products are most likely to be used," the authors conclude.
