  1. Data are expressed as mean ± SD. Statistical differences between groups were assessed by one-way ANOVA followed by Tukey’s test for Post Hoc analysis. Intra group comparisons of vitamin D concentration were performed by paired t-test analysis
  2. HFD high fat diet, ND normal diet
  3. P value and P value indicated intra group and inter group differences, respectively. The significant difference is between ND versus ND + Vit D and HFD + Vit D, ND + Vit D versus HFD and HFD versus HFD + Vit D
  4. *Mean difference was calculated by subtracting the weight of 16th from weight of 21st weeks. P < 0.05 was considered as statistically significant. n = 20 in each group
