Data are displayed as mean ± SEM
Mothers: Body weight across time was analysed by mixed repeated measures ANOVA with Sidak’s multiple comparisons test and Retroperitoneal (RP) fat was analysed by independent t-test. Main effect of maternal diet ****p < 0.0001; ***p < 0.001; *p < 0.05
Weanlings: Body weight and Retroperitoneal fat (RP) were analysed by two-way ANOVA. *p < 0.01 main effect of maternal diet; #p < 0.01 main sex effect
7 and 14 weeks: Body weight and RP fat (14 weeks only) were analysed by three-way ANOVA. *p < 0.05 main effect of maternal diet;##p < 0.01 main effect of sex; ϮϮp < 0.01 main effect of postnatal diet
Postweaning group names denote maternal and postweaning offspring diets, respectively; for example, ‘ChowCaf’ rats were from chow dams and switched to Caf postweaning
