(B) Mean data from the OGTT after 56 days of HFD feeding. (C) Area under the curve (AUC) for all the groups calculated at 120 min. Data are presented as mean ± SEM, with N = 7. Statistical comparisons were made using one-way ANOVA followed by Tukey’s post-hoc test. * p < 0.05 vs. Control, $ p < 0.05 vs. HFD.
