In the field of thyroid hormone (TH) action on energy balance, huge advances have been achieved in the past decade, from human, animal, and in vitro studies. A key achievement was the demonstration of the TH 'central' metabolic action, which was recently discovered in rodent models and challenged the previous 'peripheral' paradigm. In this opinion, we dissect and try to unify the two paradigms, from analyzing the respective bench models to extrapolating the possible translational bedside implications.
