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 .
Additive effects of isoflavones and exercise training on inflammatory cytokines and body composition in overweight and obese postmenopausal women: a randomized controlled trial
Objective Isoflavones and exercise have been shown to affect C-reactive protein ( CRP ) and body composition and to act synergistically on trunk and total fat mass ( FM ) , glucose metabolism , and lean body mass in postmenopausal women with a body mass index higher than 25 kg/m2 . We hypothesized that exercise and isoflavone supplementation ( Ex + ISO ) could reduce inflammation in the same sub population of women . The objective of this study was to investigate if 6 months of mixed exercise combined with isoflavones could have greater effects on specific inflammatory markers than exercise alone in overweight or obese postmenopausal women . Methods Thirty-four postmenopausal women aged 50 to 70 years were r and omly assigned to exercise and placebo ( Ex + PLA ; n = 15 ) or Ex + ISO ( n = 19 ) . At baseline and after 6 months , waist circumference , hip circumference , total FM , trunk FM , leg FM , and muscle mass index ( MMI ; = total fat free mass [ kg ] / height2 [ m ] ) were assessed ( dual-energy x-ray absorptiometry ) . Inflammatory markers ( CRP , tumor necrosis factor-&agr ; [ TNF-&agr ; ] , and interleukin-6 ) were obtained by enzyme-linked immunosorbent assay . T tests were used to compare groups at baseline . Results The Ex + PLA group showed significant changes in MMI ( + 0.33 kg/m2 , P ⩽ 0.009 ) and FM compartments ( waist circumference , −5.13 cm ; % FM , −1.31 % ; P ⩽ 0.001 ) , whereas inflammation remained unchanged . However , the Ex + ISO group showed significant changes in total FM ( −1.70 kg , P < 0.0001 ) , FM compartments ( hip circumference [ −2.51 cm , P = 0.019 ] , leg FM [ −1.16 kg , P = 0.037 ] , and trunk FM [ −0.72 kg , P = 0.006 ] ) , MMI ( + 0.39 kg , P = 0.011 ) , and inflammation ( CRP , −1.14 mg/L , P = 0.029 ; TNF-&agr ; , + 0.29 pg/mL , P = 0.010 ) . Conclusions Despite an increase in TNF-&agr ; , the use of isoflavones — when body weight remains stable — seems to enhance the beneficial effects of mixed-exercise training on body composition and CRP in overweight or obese postmenopausal women
