  1. Female rats had the following regime for 6-week ad libitum supply of water and food (normal-control), water supply for 1 h per day with ad libitum food intake (WRFA), and ad libitum water supply plus pair feeding of food as much as WRFA (WAFR). Rats in WR-WA had water restriction for 3 weeks and ad libitum water supply with ad libitum food intake for 3 weeks. Values represent mean ± SD (n = 10)
  2. a, b, cDifferent letters besides mean ± SD indicate significant differences among the groups at p < 0.05
