"In a study, pigs were fed either casein, a high-quality milk protein, or soy protein for 15 weeks. Results showed significantly increased muscle protein breakdown in the pigs that got the soybean protein." Lohrke, B., et al. (2001). Activation of skeletal muscle protein breakdown following consumption of soyabean protein in pigs. Brit J Nutr. 85 :447-457.
"The tofu (soy) meal produced a significant increase in the level of sex-hormone-binding globulin." Habito, R.C., et al. (2001). Postprandial changes in sex hormones after meals of different composition. Metabolism. 50:505-511.
"The activity of SHBG was an average of nearly 9 percent greater on the soy diet. Since the extra SHBG tied up circulating testosterone, that led to a relative dominance of estrogen over testosterone." Habito, R.C., et al. (2000). Effects of replacing meat with soybean in the diet on sex hormone concentrations in healthy adult males. British J Nutr. 84:557-63.
"Soy consumption by men might lower their testosterone levels." Journal of Nutrition March 2002 by Kurzer.
incase you were wondering what all that mention of SHBG is.....it is a protein which binds to testosterone and makes it ineffective
Not necessarily all muscle wasting is caused by testosterone deficiency. Levels of sex hormone binding globulin (SHBG) can become increased, leading to muscle wasting despite normal testosterone levels. Kong A and Edmonds P. Testosterone therapy in HIV wasting syndrome: systematic review and meta-analysis. Lancet Infect Dis 2(11):692-9, 2002.
