Figure 2. Effect of stress and diet on weight and food intake.

Figure 2

Initially, both stress groups gained weight (A and B) at the slower rate relative to their controls; however, this reduction in the rate of weight gain persisted past PD50 in the Chow+Stress group only. A significant difference between stress groups was observed on PD 70. Overall, rats with access to the palatable diet consumed more calories relative to chow-fed rats (C). No significant difference in preference for the palatable diet was observed (D). Lines represent mean ± SEM. ε Significant difference between Chow and Chow+Stress. φ Significant difference between Palatable and Palatable+Stress. + Significant difference between the two stress groups receiving opposite diets.
