" Your waist size is such an important predictor of health because the type of fat that is stored around your waistline—called “visceral fat” or “belly fat”—is related to the release of proteins and hormones that cause inflammation, which can in turn damage your arteries and affect how you metabolize sugars and fats. For this reason, visceral fat is strongly linked to type 2 diabetes, heart disease, stroke, Alzheimer’s, and other chronic diseases. Seeing your waist size come down is a great indicator of improving health. "
