Effect of the average maximum outdoor temperature during the 7 days preceding the study visit on energy expenditure under warm (EEwarm) and cold (EEcold) condition and on cold induced thermogenesis (CIT). (A) Outdoor temperature [°C] and EEwarm [kcal/d] show no significant correlation. p = 0.1771, R2 = 0.033. (B) Inverse correlation between EEcold [kcal/d] and the average maximum temperature during 7 days. (C) CIT [kcal/d] (difference of energy expenditure during warm and cold condition) vs. the average maximum temperature [°C] during 7 days. p = 0.0005, R2 = 0.200.
