Figure 2. Exposure to light at night increases body mass in mice.

Figure 2.

(A) Mice exposed to either dim light at night (dLAN) or constant light (LL) had increased weight gain relative to mice in a standard light/dark cycle (LD). dLAN and LL mice also reduced glucose tolerance (see (B)) despite similar levels of activity (see (C)) and total daily food consumption (not shown). However, mice exposed to LAN consumed significantly more food during the light phase (when mice would generally be resting) than those in a standard light/dark cycle (see (D)).
