Medically, a distinction is made between being overweight and being obese. The body mass index (BMI) is used to define these conditions. (...) Overweight is defined as a BMI of 25 to 29.9, and obesity is defined as a BMI of 30 or more. Body composition -the percentage of fat and muscle in the body- is also considered when obesity is defined. Women who have more than 30% body fat or men who have more than 25% body fat are considered obese. Thus, people who are very muscular and have low body fat (such as body builders) may have high BMI without being obese and without increasing health risks. |
