Science Daily - "Overeating Impairs Brain Insulin Function, a Mechanism That Can Lead to Diabetes and Obesity"
New research from Mount Sinai School of Medicine sheds light on how overeating can cause a malfunction in brain insulin signaling, and lead to obesity and diabetes. Christoph Buettner, MD, PhD, Associate Professor of Medicine (Endocrinology, Diabetes and Bone Disease) and his research team found that overeating impairs the ability of brain insulin to suppress the breakdown of fat in adipose tissue. "We are interested in understanding why people who eat too much eventually develop diabetes. Our recent studies suggest that once you overeat, your brain develops insulin resistance. Since brain insulin controls lipolysis in adipose tissue by reducing sympathetic nervous system outflow to adipose tissue, brain insulin resistance causes increased spillage of fatty acids from adipose tissue into the blood stream," said Dr. Buettner.
