 Earlier, the investigators performed a study to show the effects of bromocriptine on brown adipose tissue BAT activity the DEBAT study Medisch Etische Toetsingscommissie METC nr 2013_107. Namely, BAT, known for its capacity to dissipate excess energy, might have been involved in this process as stimulation by the sympathetic nervous system is the principal driving force in controlling BAT activity. However, the investigators have shown that bromocriptine did not influence BAT activity or energy expenditure in healthy, lean subjects.
