Values are means ± SEMs based on data obtained from 3 d food records. The HDS group received 25 g/d soy protein; the LDS group received 12.5 g/d soy protein and 12.5 g/d whey protein; and the control group received 25 g/d whey protein. *Significantly different from baseline, P < 0.05 (paired t tests). Labeled midpoint (week 4) means in a row without a common letter differ, P < 0.05 (1-factor ANOVA). HDS, high-dose soy; LDS, low-dose soy.
