Effect of 5-min RF with HFD at ZT 5 on locomotor activity, body weight, and caloric intake (Experiment 2). (A) Experimental schedule. (B–D) Change in average caloric intake of total (B), ND (C), and HFD (D) under 5-min RF. (E) Relative locomotor activity rhythm under 5-min RF with HFD at ZT 5. Red triangle represents the start of RF. Open and closed bars indicate light and dark periods, respectively. (F) Increase in body weight. Gray period indicates under-habituation. (G) Sum of relative locomotor activity during ZT 5 and 9. (H) Caloric intake during each period for ND and HFD. ND and HFD are shown in every bar. Data are presented as the mean ± SEM (n = 8). *p < 0.05, **p < 0.01, ***p < 0.001 vs. the control group (Student’s t-test); #p < 0.05, ##p < 0.01, ###p < 0.001 vs. the control group (Mann-Whitney test).
