What is overweight and obese?
If a person diagnosed as overweight or obese, this typically means that he or she has too much body fat, making the body weight greater than what is considered healthy. For many people, overweight and obesity is caused by taking in too many calories that are not burned in physical exercise.
Doctors and researchers use many different tools to assess a person’s body fat, including BMI and waist circumference. Patients are considered overweight if their BMI is greater than 25 and obese if their BMI is greater than 30. Calculate your BMI.
