Cold-induced brown fat activation improves glucose and insulin sensitivity, increases fat utilization, and protects against diet-induced obesity.

“making brown fat an interesting potential therapeutic target for the treatment of metabolic disorders”

“one study looked at men who underwent prolonged cold exposure in a cooling vest their energy expenditure increased 15 but only among those who had detectable brown fat roughly one third of this increase was due to oxidation of plasma derived glucose”

“but there's further evidence to suggest that cold induced brown fat activation affects metabolic health improving glucose and insulin sensitivity increasing fat utilization and protecting against diet-induced obesity”

“when the men received an infusion of glucose only those who had detectable brown fat showed a further increase in glucose use that's important because it indicates that brown fat plays a role in glucose utilization essentially providing an alternate pathway for glucose and in fact for healthy young people this type of glucose uptake after cold exposure exceeds the insulin stimulated uptake rate in skeletal muscle”
