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 the phytoestrogen genistein on cardiovascular risk factors in postmenopausal women
Objective : The phytoestrogen genistein has been shown to be the most efficacious in clinical and experimental studies . We studied whether genistein treatment affects some cardiovascular risk markers in postmenopausal women . Design : Sixty healthy postmenopausal women , who were 52 to 60 years of age , were enrolled in a 6-month double-blind , placebo-controlled , r and omized study . After a 4-week stabilization on a st and ard fat-reduced diet , participants were r and omly assigned to receive either genistein ( n = 30 ; 54 mg/d ) or placebo ( n = 30 ) . At baseline and after a 6-month treatment , we measured fasting glucose , insulin , insulin resistance ( HOMA-IR ) , osteoprotegerin ( OPG ) , fibrinogen , and sex hormone-binding globulin ( SHBG ) . Results : By comparison with placebo , genistein treatment decreased significantly fasting glucose  ( genistein = −8.7 ± 2.3 % ; placebo = 3.2 ± 2.3 % ; P < 0.001 ) , fasting insulin ( genistein = −12 ± 3.33 % ; placebo = 36 ± 3.29 % ; P < 0.001 ) , and HOMA-IR  ( genistein = −14 ± 5.8 % ; placebo = 42 ± 0.6 % ; P < 0.001 ) . After genistein-treatment , fibrinogen decreased ( genistein = 3.18 ± 0.12 g/L ; placebo = 3.83 ± 0.04 g/L ; P < 0.001 ) with respect to placebo . In the genistein group , serum OPG was lower ( −2 ± 0.3 % ) than in placebo ( 9 ± 1.5 % ; P < 0.001 ) , and serum SHBG was higher ( 63 ± 3.8 nmol/L ) compared with placebo ( 53 ± 2.9 nmol/L ; P < 0.05 ) . Conclusion : Our study suggests that genistein may have a favorable effect on some cardiovascular markers
