Background: Obesity is a major medical health problem. Human brown adipose tissue (BAT) is potently activated by cold exposure and is a potential novel anti-obesity target. The current gold standard for measuring BAT activity in humans is 18F-FDG PET/CT. However it has two major limitations – exposure to ionizing radiation and high cost. Since BAT is a thermogenic organ located in the supraclavicular and neck regions, we hypothesised that an increase in tempera...

Background: Obesity is a global health concern. Elevating energy expenditure (EE) would be a highly effective treatment approach to treat obesity but no current drugs can safely achieve this. Cold exposure potently increases EE through brown adipose tissue (BAT) thermogenesis in humans. Glucagon elevates EE via BAT in rodents but the mechanism in humans is unknown. We investigated for the first time the mechanism by which glucagon increases EE in humans....
