Analysis showed that soy products significantly reduced body weight , BMI , body fat percent and waist circumference in overweight or obese Asian population s ( −0.37 kg , P = 0.010 ; −0.27 kg/m2 , P = 0.042 ; −0.36 % , P = 0.032 ; −0.35 cm , P = 0.049 ) and more significant effects were observed in non-menopausal women reduced body weight ( −0.59 kg , P = 0.041 ) , BMI ( −0.59 , P = 0.041 ) and waist circumference ( −0.59 cm , P = 0.041 ) in overweight or obese population s. Conclusion : This meta- analysis showed that soy products  have weight loss effects , mainly due to soy protein , isoflavone and soy fiber
Background : The effect of soy products on the weight of overweight or obese people  is controversial , so we aim ed to conduct a systematic review and a meta- analysis of published r and omized controlled trials to analyze whether supplementation with soy products can help them to lose weight .
Weight reduction effects of a black soy peptide supplement in overweight and obese subjects: double blind, randomized, controlled study.
The present study determined the effect of black soy peptide supplementation on body weight and body fat in overweight/obese subjects . In a double-blind controlled trial , participants ( n = 80 ) were r and omized to either soy peptide supplementation ( the test group ) or to a placebo ( the placebo group ) . Sixty-four people completed the study , and anthropometric parameters , serum inflammatory markers , and leptin and lipid profiles  were measured . After 6 weeks , the test group ( n = 35 ) had significant reductions in body weight ( p = 0.003 ) and body mass index ( BMI ) ( p = 0.004 ) , body fat mass ( p = 0.038 ) . After 12 weeks , they also had significant reductions in body weight ( p < 0.001 ) , BMI ( p < 0.001 ) , body fat percentage ( p = 0.002 ) , and body fat mass ( p = 0.001 ) . However , these significance s were not observed in the placebo group ( n = 29 ) . In addition , net changes in body weight and body fat mass in the test group were significantly bigger than those in the placebo group after 12 weeks . Leptin levels were significantly reduced in the test groups ( p = 0.047 ) , but were not observed in the placebo group ( p = 0.323 ) . Interestingly , the subjects with weight reductions ≥1 kg in the test group had greater reductions in circulating leptin levels ( p = 0.002 ) . Additionally , fasting insulin levels were significantly reduced in the test groups . The conclusion is that black soy peptide supplementation may be beneficial for body weight control in overweight/obese subjects
