A team from Purdue University has developed a technique to convert the white fat (e.g. beer belly fat) into brown which is more easily burned.

The word fat is a familiar word, it is the stuff that all too easily accumulates around our bellies and thighs. However there is the white fat and the brown fat with the brown one considered healthier. A research that has been ongoing for about four years has seen the crew from Purdue University, Indiana U.S.A. develop a technique to convert white fat to the healthier brown fat which the body can burn easily. Their technique involves loading nano-particles with an existing drug like Dibenzazepine and injecting them into white fat deposits in the body.
