Very important to note that the non-fasting mice were significantly less heavy: >Compared to AL [ad libitum, "at one's pleasure"] mice, IF12 [12 hour fast], IF16 [16 hour fast], and EOD [24 hour fast] tamice demonstrated significantly lower average body weight after 3 months of IF (Data not shown). So this could be due to lower overall caloric intake.
