Abstract
Objective— Obesity is associated with endothelial dysfunction that may contribute to the development of atherosclerosis. We studied whether weight reduction improves endothelial function in overweight individuals. Methods and Results— Flow-mediated endothelium-dependent vasodilation of the brachial artery was measured in 67 adults (age: 46±7 years, body mass index: 35.2±5.4 kg/m2) before and after a 6-week weight reduction program induced by very-low-calorie diet (daily energy: 580 kcal/2.3 MJ). Caloric restriction reduced body weight from 101±18 to 90±17 kg. Flow-mediated vasodilation increased from 5.5%±3.7 to 8.8%±3.7% (P<0.0001). Nitrate-mediated vasodilation was not significantly affected. The improvement in flow-mediated dilation was associated with the reduction in plasma glucose concentration (P=0.0003). This relationship was independent of changes in weight, serum lipids, oxidized LDL, C-reactive protein, adiponectin, blood pressure, and insulin. Conclusions— Weight reduction with very-low-calori...Keywords
