Obese in the group name indicates diet-induced obese rats that underwent the respective prepregnancy interventions, except Obese-HFS that remained untreated and consumed HFS diet throughout the study. Lean in the group name indicates a lean reference group that never underwent the obesity induction period and consumed control AIN-93 diet throughout the study. Baseline weight refers to body weight after the obesity induction period and just before starting the diet and drug preconception treatments. Mean values with different superscripts are significantly different between treatment groups (p < 0.05). For example, a group with “a” is significantly different from a group with “b” but not from a group with “ab.”
