Maternal body weight in control diet (CD)-fed and high-fat diet (HFD)-fed dams during pregnancy and lactation (n = 16 rats/group; A) and their male offspring body weight from birth to 8 wk old (n = 20 rats/group; B). C, control days before mating; P, pregnancy; L, lactation; W, week. Rats were divided into the following groups: offspring from CD-fed dams sucked by CD-fed dams (OCC group), offspring from HFD-fed dams suckled by CD-fed dams (OHC group), offspring from CD-fed dams sucked by HFD-fed dams (OCH group), and offspring from HFD-fed dams suckled by HFD-fed dams (OHH group). *P < 0.05 OCC vs. OCH or OHH; #P < 0.05 vs. CD dams.
