See Table 2 for experimental detail. Male Sprague-Dawley rats (Charles River Laboratories) were fed a LF or HF diet between 4 and 13 week of age. At 13 weeks of age, rats were placed in a computer-controlled Oxymax instrument (an open circuit calorimeter; Columbus Instruments, OH) to measure 24-h O₂ consumption, CO₂ production and heat production (34). IWG: initial body-weight gain during the first week; RQ_S and HP_S are the 1^st PC scores of RQ and HP, respectively.
