New Role For Brown Fat in the Control of Metabolism

January 08, 2017 - Admin

Scientists have known about brown fat for years. However, it was only recently that we discovered its importance in human physiology. Unlike white fat, brown fat dissipates energy as heat instead of storing it as fat. Activating brown fat increases calorie burning, reduces whole-body fat and lowers blood sugar and blood fat levels. New research shows that brown fat also secretes chemicals that help regulate metabolism. Exposure to cold is the best way to increase brown fat stores. However, exercise can make regular fat cells more like brown fat, which would promote weight control. (Trends in Endocrinology & Metabolism, 26: 231-237, 2015)
