(A) Serum corticosterone concentrations were reduced in LL mice but not in DM mice at the two time points measured, suggesting that glucocorticoids did not mediate the changes in body mass (*P ≤ 0.05 from LL and DM). (B) Mice exposed to LL and DM conditions ate more food during the light phase than during the dark phase, behavior that is atypical in nocturnal animals (*P ≤ 0.05). (C and D) Body mass (C) and blood glucose levels (D) are associated with percentage of daytime food consumption. (C) Percentage of food consumed during the day correlated with final blood glucose levels obtained in the GTT. (D) Body mass at the conclusion of the study correlated positively with percentage of daytime food intake.
