Obesity is caused by eating more calories than you use over a long period of time, leading to excess body fat. It is often measured by your body mass index, or BMI. Obesity increases your risk for diabetes, heart disease, and other conditions, but weight loss, healthy eating, and exercise can decrease these risks.
