A: Daily food consumption (kcal/day) over the first 80 days following introduction of the HF diet (open circles) compared with rats maintained on the chow diet (closed circles). The same pattern continued for the remainder of the experiment. Food intake was significantly different between groups commencing at day 1 through the end of the experiment (P<0.05 by t-test).
B: Cumulative food consumption (kcal) from day 11 through day 190, representing the period after the acute hyperphagic phase. *P <0.007 for difference from chow-fed by t-test.
C: Body weight in rats following introduction of the HF diet (open circles) compared with rats maintained on the chow diet (closed circles). Body weight was significantly different between groups beginning at day 32 through the end of the experiment (P<0.05 by t-test).
Values represent the mean ± SE of 12 rats per group.
