Health professionals often use BMI and waist circumference together to assess whether someone is overweight or obese and to assess their risk of cardiovascular disease and diabetes. Waist circumference is considered a good estimate of your body fat, especially your internal fat deposits, and your likelihood of developing weight-related disease. Two methods that are commonly used to estimate whether you are a healthy weight or not are body mass index (BMI) and waist circumference.
