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 .
Effects of soya isoflavones and exercise on body composition and clinical risk factors of cardiovascular diseases in overweight postmenopausal women: a 6-month double-blind controlled trial.
Results from a pilot project indicate that isoflavones and exercise could have an additive effect on body composition and clinical risk factors of CVD in postmenopausal women . The objective of the present study was to assess the combined effect of exercise and isoflavones in overweight-to-obese postmenopausal women . In this double-blind r and omised controlled trial , 100 overweight-to-obese ( BMI 29·9 ( sd 3·2 ) kg/m2 ) postmenopausal women were assigned to four groups : ( 1 ) placebo ( PLA ) ; ( 2 ) isoflavones ( ISO ) ; ( 3 ) exercise and placebo ( Ex+PLA ) ; ( 4 ) exercise and isoflavones ( Ex+ISO ) . The supplementation contained 70 mg/d of isoflavones . Exercise consisted of three weekly sessions of resistance training and aerobics . Outcome measures included fat mass ( FM ) , lean body mass ( LBM ) , bone mineral density , lipid profile , fasting glucose , fasting insulin and insulin resistance ( homeostasis assessment model ) . The main effects of exercise were observed for total FM ( P = 0·02 ) , FM% ( P < 0·01 ) , trunk FM% ( P = 0·05 ) , arm FM% ( P < 0·01 ) , leg FM% ( P = 0·02 ) , arm LBM ( P < 0·01 ) , leg LBM ( P = 0·02 ) and C-reactive protein ( P < 0·01 ) . A main effect was detected for isoflavones in improving leg FM% ( P = 0·05 ) . No interactions were observed between isoflavones and exercise . In conclusion , it was observed that 6 months of exercise brought favourable changes in total FM , FM% and LBM in overweight postmenopausal women . No synergistic effects were observed between exercise and isoflavones . However , isoflavones could have a beneficial effect on leg FM%
