BAT contributes to energy expenditure. Weight gain and obesity are caused by chronic periods of positive energy balance. Energy
intake comes from food consumption, whereas the major contributors to expenditure are exercise and basic metabolic processes.
The studies reviewed here suggest that BAT activity could impact daily energy expenditure. BAT dissipates energy as heat and
can thus counteract weight gain. Interindividual variability in the amount or function of this tissue may impact body weight.
In addition, therapeutic expansion/activation of this tissue may prove to be an effective therapy for obesity. WAT, white
