Abstract:
Chitosan, hydroxycitrate and L-carnitine have been known to be antiobesity components. The purpose of this study was to evaluate the combined effects of chitosan, hydroxycitrate and L-carnitine mixture as a potential antiobesity supplement in overweight women. Pre-menopausal healthy females who were overweight (percent ideal body weight >110) were included in this study. Forty-nine subjects randomly received a placebo (n=25) or antiobesity-supplement (n=24), which was a mixture of chitosan, hydroxycitrate, and L-carnitine. Before and after the eight-week experimental period, anthropometric parameters, blood components and computerized tomography were measured. At baseline, the two groups were well matched in terms of age, body mass index and lipid profile. After the eight weeks of potential antiobesity supplementation, the subjects' body fat percent had decreased significantly (p<0.001) by 5.6% (39.1+/-1 vs 36.9+/-1%) while lean body mass increased (p<0.01). Vsceral fat area at the L4 vertebra decreased significantly (p<0.01) by 8.6% in the supplemented group and the total fat area at the L4 vertebra showed a tendency to decrease (p=0.051) by 2.4%. Also, in the group given the antiobesity-supplement rather than the placebo, the fasting triglyceride level decreased significantly (p<0.05) by 10.0%. In addition, serum total cholesterol levels in the antiobesity-supplement group showed a tendency to decrease (p=0.159) by 2.7% (194+/-6 vs 189+/-6 mg/dl). No side effects were found in either group during the intervention. In conclusion, the present study demonstrated that taking a mixture of chitosan, hydroxycitrate, and L-carnitine as a potential antiobesity supplement for eight weeks produced advantageous changes in the weight and visceral fat accumulation of overweight women without any side effects.
