Until about four years ago, scientists thought brown fat existed only in infants.Infants cannot shiver, so they use brown fat as a means to keep warm.
Several new studies have shown the existence of brown fat in human adults for the first time – present in the neck, the upper back and elsewhere.
We now have proof that this brown fat actually burns calories at a significant rate – like a furnace.
Brown fat is turned on when people get cold and during exercise.
Scientists are now exploring ways to turn on brown fat without exposing people to cold temperatures or prolonged exercise.
A group of researchers are presently looking at a number of hormones, and other compounds, to determine which are most effective and potent at activating brown fat.Hopefully, they won’t take long.
