A DIETARY SUPPLEMENT WITH BEAN EXTRACT DECREASES BODY WEIGHT, BODY FAT, WAIST CIRCUMFERENCE AND BLOOD PRESSURE IN OVERWEIGHT AND OBESE SUBJECTS

摘要

Dietary supplements have frequently been reported to decrease body weight in short-term studies, but few studies have examined dietary supplements and changes in body weight while testing the impact on blood pressure in long-term studies. The aim of this study was to evaluate the long-term effects of a dietary supplement of a white kidney bean extract on body weight, % body fat, waist circumference and systolic and diastolic blood pressures without changes in lifestyle. Sixty-two overweight and obese volunteers were randomized to receive either a dietary supplement or a placebo. Two capsules of the dietary supplement or the placebo were administered three times daily for 3 months during this double-blinded, randomized phase. Excretion of fat infeces was measured. The Supplement Group was then invited to participate in an open-label second phase for 9 months. At 12 months significant reductions were found in body weight, % body fat, waist circumference, and in systolic and in diastolic blood pressures. The bean extract significantly increased fat excretion infeces.
