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 .
Isoflavones and clinical cardiovascular risk factors in obese postmenopausal women: a randomized double-blind placebo-controlled trial.
AIMS To investigate whether 6 months of isoflavone supplementation , which has been shown to be sufficient to improve menopausal symptoms , could also improve clinical cardiovascular disease ( CVD ) risk factors in obese postmenopausal women , compared with a placebo . METHODS A r and omized double-blind placebo-controlled trial in which 50 obese postmenopausal women were divided into two groups ( isoflavones vs. placebo ) to examine the effect of 6 months of isoflavone supplement ( 70 mg ) on clinical CVD risk factors . Body composition ( DXA ) , medical and social characteristics , daily energy expenditure ( accelerometry ) , dietary intake ( 3-day dietary record ) , and blood biochemical analyses ( lipid profile , insulin , glucose ) were obtained . RESULTS At baseline , no differences were found between groups except for fasting insulin level . Women were thus considered at risk of CVD based on body composition but not biochemical variables . After 6 months , we observed that isoflavones did not favorably affect risk factors predisposing to CVD ( biochemical or body composition ) compared with placebo . CONCLUSIONS Isoflavones given for 6 months should not be considered protective against clinical CVD risk factors in obese postmenopausal women . Nevertheless , further research is needed to verify if isoflavones protect against CVD disease risk factors when administered for a longer duration or when combined with nutritional or exercise interventions . It would also be pertinent to study their effects in women with specific metabolic abnormalities
