Distance traveled (A), time ambulatory (B), time stereotypic (C), and ambulatory episodes (D) during the time interval preceding meal anticipation (1300–1700) in response to chronic caloric restriction, 70% caloric restriction for 8 wk, (shaded bars), or ad libitum feeding (open bars) in OP, OR, and SD rats. *P < 0.05 and #P < 0.005 compared with ad libitum feeding within the same group; n = 9–10/group. Values are presented as means ± SE.
