(A) Study protocol overview. The study was designed as a randomized, single blind, cross-over intervention. After enrollment, the volunteers received a weight maintenance diet for 2 days before undergoing 12-h respiration chamber and hormonal axes recording. After 36 h of recovery, the study volunteers underwent the same procedure at the second experimental temperature (see text for details). (B) Blood samples collection and procedures during a 12-h respiration chamber stay. Blood sampling was performed through an airtight sampling port every hour except during the first 2 h of the recording and the first 2 h after the meal when the sampling was performed every 30 min.
