What is obesity?
Maintaining a healthy body weight is one of the best ways to avoid weight-related health problems, such as type 2 diabetes or heart disease. But what exactly is a healthy body weight? A measurement based on your height and weight, called your body mass index or BMI, is considered to be a better measure of health risk than just your weight in pounds. In fact, the medical terms "overweight" and "obesity" are based on BMI values. A BMI between 25 and 30 is defined as overweight, and a BMI of 30 or more is considered obese. The higher your BMI, the greater your risk of developing a weight-related illness.
