Increasing healthy brown fat might help weight management and reduce symptoms of diabetes. Engineers have developed a simple, innovative method to directly convert white fat to brown fat outside the body and then reimplant it in a patient. The technique uses fat-grafting procedures commonly performed by plastic surgeons, in which fat is harvested from under the skin and then retransplanted into the same patient for cosmetic or reconstructive purposes.

Fat production and burning are synchronized in livers of mice with obesity ... read more
July 26, 2018
Mice fed a fattening diet develop new liver circadian rhythms that impact the way fat is accumulated and simultaneously burned. The team found that as liver fat production increases, surprisingly, so does the body's ability to burn fat. These opposing physiological processes reach their peak activity each day around 5 p.m., illustrating an unexpected connection between overeating, circadian rhythms, and fat accumulation in the liver.
