From: Type of diet modulates the metabolic response to sleep deprivation in rats
A) Change in food intake of rats fed a chow pellet diet. REC = Sleep Recovery. The mean percentage change (mean ± SE) of food intake for control (■; n = 10) and sleep-deprived (SD) (▲; n = 20) rats compared to pre-sleep deprivation (0 h) and 24 h, 48 h, 72 h and 96 h of sleep deprivation. The upper panel shows the mean ± SE food intake (Kcal/day) at 96 h of sleep deprivation and after 24 h sleep rebound (n = 10). *Different from 0 h, Tukey test, p < 0.05; **Different from respective 0 h and time-corresponding SD group, Tukey test, p < 0.05. B) Removed food (%) of rats fed with high-fat pellets. REC = Sleep Recovery. The mean percentage change (mean ± SE) of food removed for control (■; n = 10) and sleep-deprived (SD) (▲; n = 19) rats compared to pre-sleep deprivation (0 h) and 24 h, 48 h, 72 h and 96 h of sleep deprivation. The upper panel shows the mean ± SE food intake (Kcal/day) at 96 h of sleep deprivation and after 24 h sleep rebound (n = 9). **Different from 0 h and SD group, Tukey test, p < 0.05. C) Change in food intake of rats fed a liquid diet. REC = Sleep Recovery. The mean percentage change (mean ± SE) of food intake for control (■; n = 9) and sleep-deprived (SD) (▲; n = 18) rats compared to pre-sleep deprivation (0 h) and 24 h, 48 h, 72 h and 96 h of sleep deprivation. The upper panel shows the mean ± SE food intake (Kcal/day) at 96 h of sleep deprivation and after 24 h sleep rebound (n = 9). *Different from 0 h, Tukey test, p < 0.05.
