Daily energy intakes (A), daily chow intakes (B), relative total energy intake (C), relative total energy intake per food component (D), daily body weights (E), and body weight change (F) in the nonpregnant and pregnant states in chow and choice rats. Choice-diet-fed rats had greater daily energy intakes compared with chow-diet-fed rats and increased intake of pelleted chow during pregnancy as compared with the prenatal period. Although energy intakes remained higher in choice group during pregnancy, choice-diet-fed rats gained less weight during pregnancy compared with chow-diet-fed rats (calculated in a subset of animals that were euthanized on gestational day 20). BL, baseline. Data are means ± SE (n = 8 rats/group). Two-way mixed model ANOVA with repeated measures followed by Tukey’s post hoc test (A, B, and E), Student’s t-test (C), one-way ANOVA followed by Tukey’s post hoc test (D), and two-way ANOVA with repeated measures followed by Sidak’s post hoc test (F). *P < 0.0002 vs. lard, vs. sucrose
