What is Obesity?
Obesity is a treatable disease that is a worldwide health concern associated with having an excess amount of body fat. It is caused by genetic and environmental factors and can be difficult to control through dieting alone. Obesity is diagnosed by a healthcare provider and is classified as having a body mass index (BMI) of 30 or greater. Nearly 40 percent of Americans have obesity.

Body Mass Index (BMI)
Body fat is hard to measure directly. So it is often measured by body mass index (BMI). BMI measures weight related to height. It is a common way to measure body fat and is one tool healthcare providers use when talking about weight.
To find your BMI, please see the BMI chart here.
While BMI is widely used in the healthcare community, it is not perfect. BMI is not a percentage of body fat, and it is only part of a diagnosis of obesity. Ask your healthcare provider for other ways of determining obesity.
How Weight is Categorized
Having a BMI in the overweight range (25.0 29.9) is a health concern. Excess weight is hard on your body. It can lead to other health problems including obesity. People who have a BMI in the overweight range and have other health problems (such as type 2 diabetes or heart disease) need to see their healthcare provider for treatment options.
