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 .
Soy compared to casein meal replacement shakes with energy-restricted diets for obese women: randomized controlled trial.
Recent studies suggest that obese individuals lose weight more rapidly and lose more total weight with soy protein than with animal protein as a major diet component . The purpose of the present study was to evaluate the weight-loss efficacy and changes in body composition , waist circumference , blood pressure , and levels of plasma glucose , insulin , serum lipids , C-reactive protein , and homocysteine from consumption of either 3 soy shakes or 3 casein shakes daily as part of a 16-week , energy-restricted diet for obese women . Forty-three women with body mass index values of 30 to 40 kg/m(2 ) were r and omized to intensive dietary interventions using either casein ( n = 21 ) or soy ( n = 22 ) shakes . Subjects were instructed to consume 3 shakes , 1 prepackaged entrée , and 5 servings of fruits or vegetables daily to achieve an energy intake of 4.5 to 5.0 MJ/d . Subjects attended classes weekly or biweekly . Weight , body fat , lipid , and glucose measurements were obtained at baseline and at 8 and 16 weeks . For both groups combined , subjects lost 8.1 % of initial body weight ( 7.7 kg ) at 8 weeks and 13.4 % ( 12.7 kg ) at 16 weeks . Weight loss from baseline did not differ significantly by group and , for completing subjects , was 14.0 % + /- 1.2 % ( mean + /- SE ) for casein and 12.8 % + /- 1.4 % for soy . With the intention-to-treat analysis , weight losses at 16 weeks were 12.5 % + /- 1.4 % for casein and 11.3 % + /- 1.2 % for soy . Body fat losses were 23.7 % + /- 2.0 % for casein and 21.8 % + /- 2.4 % for soy and did not differ significantly . Both study groups lost significant amounts of weight with a highly structured behavioral program incorporating 4 meal replacements and vegetables and fruits . Differences in weight loss and body composition changes between casein and soy treatments were not significant
