Unlike white fat cells, which store the body’s surplus energy in the form of fat, brown fat cells have the unique property of being able to burn energy and turn it into heat.

The study now published by the Gothenburg researchers shows for the first time that people have at least two different kinds of brown fat cells – not just one as was previously thought.

According to Sven Enerb√§ck, who heads the country’s leading research group in the study of fat cells and metabolism, this is an interesting discovery.

“We already know that those of us who have more brown fat tissue have a smaller risk of developing type 2 diabetes. With these new results, we should eventually be able to develop methods for stimulating the brown fat tissue, so that some of the surplus energy we store in the form of fat tissue can be converted into heat. Such a treatment could both prevent obesity and reduce the risk of developing obesity-related diseases such as type 2 diabetes,” says Sven Enerb√§ck.

The researchers call the new type of brown fat tissue that they have discovered “classical brown fat”. According to the Gothenburg study, young people have this classic brown fat tissue, but it seems to disappear during adolescence.

“One idea is to be able to “reactivate” the classical brown fat tissue in older people and so treat obesity,” says Sven Enerb√§ck.

The research into brown fat tissue is being done in close cooperation with researchers at Linköping University.

The article ‚ÄúEvidence for two types of brown adipose tissue in humans‚ÄĚ is published online in Nature Medicine on April 21.
