Values are the means ± SEM of eight different rats. * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001 compared to respective control (one-way ANOVA followed by Tukey post-test). ME= metabolizable energy; control (C), fructose (F), control rescue (CR), fructose rescue (FR). Energy balance values are referred to three weeks of control diet (C) or fructose-rich diet (F), or three weeks of control diet given to rats following the period of control diet feeding (CR) or fructose-rich diet feeding (FR).
