Data expressed as means ± SEM. The capital letters refer to comparison between times, while lower case letters refer to the comparison between SD and HFD groups. Different letters indicate a significant difference (p < 0.05, Two-Way ANOVA, post hoc Tukey Test)
*Adiposity index values were transformed in arc sen prior to statistical analysis and they are expressed as mean
