Green Coffee Bean Extract May Promote Weight Loss
Study authors conducted a 22-week crossover trial examining the efficacy and safety of a commercial green coffee extract product (GCA(TM)) at reducing weight and body mass. Subjects (n=16) received high-dose GCA (1050 mg), low-dose GCA (700 mg), or placebo in separate 6 wk treatment periods followed by 2 wk washout. Significant reductions were observed in body weight (-8.04 +/- 2.31 kg), body mass index (-2.92 +/- 0.85 kg/m(2)), and percent body fat (-4.44% +/- 2.00%), as well as a small decrease in heart rate (-2.56 +/- 2.85 beats per minute). Body mass index for six subjects shifted from pre-obesity to the normal weight range (<25.00 kg/m(2)). Results suggest that GCA may be an effective nutraceutical in reducing weight in pre-obese adults, and preventing obesity in overweight adults.
