Cold conditions are the primary driver of brown fat activation, increasing energy expenditure.
Research during 2019 highlighted how activating BAT can improve metabolic health, specifically: Activator 2019bat
A significant 2019 report highlighted a compound called 4-methylumbelliferone (4-MU) as a novel way to activate BAT. Studies showed 4-MU activates BAT independently of adrenergic signaling (the typical, often stressful, pathway), potentially offering a way to boost metabolism without triggering fight-or-flight responses. Cold conditions are the primary driver of brown
