Effect of housing temperature on food intake and body weight (experiment 1). Female mice were divided into 3 groups: ad libitum fed and housed at 22°C (AL/22), ad libitum fed and housed at 27°C (AL/27), and pair fed the same amount as the AL/27 group and housed at 22°C (PF/22). Food was provided once daily at 1200. A: food consumption was recorded every other day; data represent the mean food intakes over the 4-wk experiment. B: body weights were recorded once/wk; data represent the mean weekly body weights. All values are expressed as means ± SE; n = 3–5 for each group. One-way ANOVA with Tukey's post hoc test was used for all between-group analyses; means not sharing a common letter are significantly different (P < 0.05).
