Effects of RYGB and VSG on brown and beige adipose tissue thermogenesis in rodents and humans. The studies discussed in this Review generally show a stimulatory effect of RYGB and VSG on brown and/or beige adipose tissue thermogenesis involving canonical, UCP1-dependent or non-canonical, UCP1-independent mechanisms. cBAT refers to classical BAT which is the interscapular depot in rodents and supraclavicular depot in humans. sWAT refers to subcutaneous WAT which is the inguinal depot in rodents and abdominal depot in humans. vWAT refers to visceral WAT which is the epigonadal depot in rodents and omental depot in humans. Note how sWAT in rodents and vWAT in humans have more browning potential, respectively.
