Effects of daily 1-h operant self-administration of Chow, HSD, or HFD on correlations between 23-h home-cage food intake and (A–C) 1-h food intake, (D–F) inter food interval (IFI), or (G, H, and K) entropy in female Sprague Dawley rats (n = 10/group). For such analyses, the averages of days 13–21 were used, a period in which HSD 23-h food intake started being significantly lower than controls. Rats were given the chance to self-administer one of the three diets in a fixed ratio 1 schedule during a 21-day period. Chow was otherwise freely available in the home cages.
