Values are means ± SEM (n = 8–11 per group). Serum satiety hormones, HOMA-IR, and CISI were measured at 17 weeks of age. Energy intake was measured for five consecutive days in the week indicated and averaged to kcal/day per rat across an n = 2 male or n = 3 female rats per cage.
abValues without common superscript are significantly different within a sex (p < 0.05).
