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 .
Effect of a daily supplement of soy protein on body composition and insulin secretion in postmenopausal women.
OBJECTIVE To determine whether a supplement of soy protein improves body composition , body fat distribution , and glucose and insulin metabolism in postmenopausal women without diabetes compared with an isocaloric casein placebo . DESIGN R and omized , double-blind , placebo-controlled 3-month trial . SETTING Clinical Research Center . PATIENT(S ) Fifteen postmenopausal women . INTERVENTION(S ) Computed tomographic scans at L4/L5 , dual energy x-ray absorptiometry , hyperglycemic clamps . MAIN OUTCOME MEASURE(S ) Total fat , total abdominal fat , visceral fat , subcutaneous abdominal fat , and insulin secretion . RESULT ( S ) Weight by dual energy x-ray absorptiometry did not change between groups ( + 1.38 + /- 2.02 kg for placebo vs. + 0.756 + /- 1.32 kg for soy , mean + /- SD ) . Total and subcutaneous abdominal fat increased more in the placebo group than in the soy group ( for differences between groups in total abdominal fat : + 38.62 + /- 22.84 cm(2 ) for placebo vs. -11.86 + /- 31.48 cm(2 ) for soy ; subcutaneous abdominal fat : + 22.91 + /- 28.58 cm(2 ) for placebo vs. -14.73 + /- 22.26 cm(2 ) for soy ) . Insulin secretion , visceral fat , total body fat , and lean mass did not differ between groups . Isoflavone levels increased more in the soy group . CONCLUSION ( S ) A daily supplement of soy protein prevents the increase in subcutaneous and total abdominal fat observed with an isocaloric casein placebo in postmenopausal women
