WEIGHT REDUCTION EFFECTS OF YEAST HYDROLYSATE BELOW 10 kDa ON OBESE YOUNG WOMEN

Abstract

We investigated the antiobesity effects of yeast hydrolysate below 10 kDa on obese young women for the 4 weeks to assess its possibility as a dietary supplement. Subjects were randomly assigned to the placebo group (n = 10) and yeast hydrolysate below 10 kDa 1 g/day (YH) group (n = 10). The results showed body weight was lost significantly (P < 0.05) in the YH group (1.68 kg) compared with placebo group (0.71 kg). And the percent ideal body weight (PIBW) and body mass index (BMI) of the YH group (PIBW: 3.04%; BMI: 0.65 kg/m2) were decreased significantly (P < 0.05) compared with placebo group (PIBW: 1.26%; BMI: 0.27 kg/m2). The reductions of fat mass, percent body fat, body circumference and skinfold thickness also were slightly higher in the YH group than placebo group, however, the significant effects in these variables were not observed.
