Fig. 2.

Temporal food intake analysis during baseline week (A), and week 1 (B, E), week 2 (C, F) and week 6 (D, G) of dietary manipulation. (B–D) Temporal food intake structure showing caloric intake excluding that from high fat diet during scheduled feeding. (E–G) Temporal food intake structure showing total caloric intake including calories from high fat diet during scheduled feeding. Light shaded area indicates dark phase; dark shaded area indicates scheduled access to high fat diet. *P < 0.05 vs. CON by two-way repeated measures ANOVA and Student–Newman–Keul post hoc test. For clarity, P < 0.01 and P < 0.001 are not differentiated from P < 0.05, and diagrams (E–G) display only significant differences during scheduled feeding time for 2 h-HF and 2 × 1 h-HF vs. CON (ZT14, ZT19, ZT20 and ZT23). Data are presented as mean ± SEM.
