Bad fat” could be made to turn over a new leaf and combat obesity by blocking a specific protein, scientists have discovered.
Most fat in the body is unhealthy “white” tissue deposited around the waist, hips and thighs. But smaller amounts of energy-hungry “brown” fat are also found around the neck and shoulders. Brown fat generates heat by burning up excess calories.
Now scientists experimenting on lab mice have found a way to transform white fat into “beige” fat – a healthier halfway stage also capable of reducing weight gain.
Beige fat was discovered in adults in 2015 and shown to function in a similar way to brown fat. Lodhi’s team found that blocking a protein called PexRAP caused white fat in mice to be converted to beige fat that burned calories.
