What Does Obesity Mean?
Obesity is used to describe an individual weight or accumulation of body fat that is considered unhealthy. The most common measure to determine obesity is the body mass index (BMI), although this measure is inherently limited in its accuracy. Specifically, an adult with a BMI of 30 or higher is considered obese. An adult with a BMI between 25 and 29.9 is considered overweight. The terms obesity and overweight in this context refer specifically to body fat and not muscle or other weight.
