Data are means ± SE. Metabolizable energy intake (MEI) was calculated by multiplying food weight (g) by caloric density of respective diet (CON, 3.85 kcal/g: DIO, 5.24 kcal/g). CON, never-obese control. Data for any variable not marked by the same letter are significantly different by 2-way ANOVA with Tukey's post hoc analysis.
