Energy balance

Chronic cold acclimation increases the volume and oxidative capacity of metabolically active brown adipose tissue in humans, leading to increased energy expenditure and improved insulin sensitivity.

Engage in chronic mild cold exposure (around 19°C or 66°F) for extended periods daily. Over time, this increases the volume and oxidative capacity of your brown fat, boosting your resting energy expenditure and improving how your body handles insulin after meals. This is a sustainable, non-pharmacological way to leverage your body's natural thermogenic machinery.

GoodSupportsHIGH confidence
Very recently, chronic cold acclimation in human subjects was reported to increase the volume of metabolically active BAT, increasing its oxidative capacity, therefore its contribution to cold-induced thermogenesis... Cold-acclimation was also shown to increase diet-induced thermogenesis and postprandial insulin sensitivity.
