We read with interest the study by Bahler et al. [1] that discusses the findings observed in two studies comparing brown adipose tissue (BAT) activity and volume in healthy young white Caucasians and South Asians [2,3]. While Admiraal et al. [2] found no differences in BAT activity and volume between groups, Bakker et al. [3] reported lower BAT volume in South Asians, despite the fact that both studies were comparable in terms of age, body mass index, sex, ethnicity and country of the participants.
