29 Nov 2018 --- A new study published in Nature Communications suggests that a protein molecule found in blood, BMP8b, can help treat obesity. Increased levels of BMP8b may promote the functions of “brown” fat which is the kind of fat the body burns for energy. The study was carried out in mice but researchers are hopeful it could be applied in humans too, perhaps with a drug that increases the levels of BMP8b, in turn, treating obesity more effectively.
