Caloric intake, physical activity, energy expenditure, and RER in ad libitum control and high fat diet fed mice. Caloric intake, physical activity, energy expenditure, and RER were monitored continuously using a CLAMS. Data are reported as mean ± SEM for 25–27 mice per experimental group.

	Control Diet Ad Libitum	High Fat Diet Ad Libitum
24-hr Cumulative Caloric Intake (kcal/24-hr)	14.4 ± 0.6	14.8 ± 0.4
24-hr Cumulative Physical Activity (beam breaks; A.U.)	32703 ± 1856	24257 ± 1353*
24-hr Average Energy Expenditure (kcals/hr)	0.355 ± 0.012	0.402 ± 0.018*
24-hr Average Respiratory Exchange Ratio	0.981 ± 0.008	0.856 ± 0.005*
