For aim 2, Chi-squared tests were performed in order to examine proportion differences in animals in each condition that presented signs of liver or kidney damage. One-way ANOVAs were performed for

each serum/whole blood variable. For tracking changes in body composition Selleck AZD2014 variables, a two-way ANOVA (dose x time) was performed. Unless otherwise stated in figures and tables, all data were expressed as means ± standard error values and significance was set at p < 0.05. Results Post prandial serum leucine and insulin differences between WPI and WPH Figureb 1A shows the leucine responses to the WPI and WPH-based supplement relative to rats that were not gavage-fed. In the WPI condition, serum leucine did not statistically increase relative to the control rats that were not gavage-fed. In contrast, WPH significantly increased at 15-min

post-ingestion relative to the unfed control rats (p = 0.01). Importantly, a significant difference in circulating leucine LY2835219 at 15 minutes post-WPH gavage existed relative to 15 minutes post WPI-gavage (p = 0.04), but not at other time points. Figure 1 Circulating postprandial leucine (A) and insulin (B) responses of a WPH-based supplement versus WPI. Inset figures represent postprandial areas under the curve (AUCs) of each condition. All data are presented as mean ± SE; n = 4–6 rats per time point. Abbreviations/symbols: † = greater serum value than 3-h fasting concentrations for the respective supplement; * = WPH > WPI at a postprandial time point (p < 0.05). Figureb 1B outlines the insulin responses to the WPI and WPH-based supplement. For post-WPI gavage, relative to the control rats that were not gavage-fed, no significant increases occurred in serum insulin very at 60 minutes, and 120 minutes, although there tended to be an increase at 30 minutes post-gavage (p = 0.09). For post-WPH gavage, relative to the control rats that were not

gavage-fed, a significant increase occurred in serum insulin 60 minutes post-WPH gavage (p = 0.01), while there were no significant increases in serum insulin at 30 minutes and 120 minutes (p > 0.05). Comparing the insulinogenic responses of both protein sources against one another at each time point importantly revealed that the WPH-based supplement elicited a significantly greater increase in insulin relative to WPI 60 minutes post-gavage (p = 0.001). Body composition and food intakes following 30 days of feeding with different doses of the WPH-based supplement When comparing the low-dose WPH, medium-dose WPH, high-dose WPH, and water only, DXA analysis demonstrated that there were no significant between-condition differences from 7 days to 30 days in fat mass (dose x time interaction p = 0.90; Figureb 2). Similarly, there were no between-condition differences in total lean body mass (dose x time interaction p = 0.
