Changes in (A ) body weight and (B ) food intake in the 3 groups during the 7-day study period. (A ) Day 6 and 7, leptin < control, P < (B ) ∗P < Leptin and pair fed vs. control.

3. Figure 2
Effects of leptin and caloric restriction on plasma ghrelin concentration. Bars represent average ± standard error of values from 7 or 8 animals per group. ANOVA among groups, P = ∗Indicates statistical difference from control and leptin using Bonferroni correction comparing different subgroups (P < 0.005).

4. Figure 3
(A ) Correlation between plasma ghrelin concentration and body weight changes during 1 week in the pair-fed calorie-restricted (○) and control (□) rats. A statistically significant negative correlation was also observed in the calorie-restricted group considered separately (R = −0.74; P < 0.05). (B ) Correlation between plasma ghrelin concentration and body weight changes during 1 week in the leptin-treated rats.
