For a number of years, scientists have been studying “brown fat.”
Brown fat is a heat-generating type of fat that burns energy instead of storing it, and this may have important implications when it comes to weight loss.
Human newborns have a supply of brown fat to keep warm, but by adulthood they lose most of their stores of it.
Brown fat has been located in the neck area, around blood vessels (helping to warm your blood), and “marbled” in with white fat in visceral fat tissue.
In a new study, scientists found that they were able to activate the brown fat still present in adult men by exposing them to cold temperatures.
The men burned more calories when cooled, and lost white fat, the kind that causes obesity.
