Postprandial Oxidative Metabolism of Human Brown Fat Indicates Thermogenesis (Cell Metabolism)

Using PET/CT imaging, U Din et al. show that eating a carbohydrate-rich meal triggers human brown adipose tissue (hBAT) thermogenesis to the same extent as cold stress, though the substrates used are different. Glucose and LPL-derived fatty acids are preferentially taken up by hBAT in the postprandial state.
