Maternal body composition and gestation weight gain. Prepregnancy body weight (A–C), prepregnancy body composition (D–F), pregnancy weight gain (G–I), and end-gestation body weight (J–L) of dams during their 1st, 2nd, and 3rd pregnancies. For pregnancy no. 1, n = 9–10 (LF) and n = 29–32 (HF). For pregnancy no. 2, n = 8–10 (LF), n = 16–22 (HF), and n = 6–10 [2nd pregnancy diet reversed (DR2)]. For pregnancy no. 3, n = 7–10 (LF), n = 6–11 (HF), and n = 8–11 [3rd pregnancy diet-reversed (DR3)]. *P < 0.05, **P < 0.01, and ***P < 0.001 vs. LF dams; #P < 0.05, ##P < 0.01, and ###P < 0.001 vs. HF dams.
