How do you know if you are obese?
Total Body Composition Testing is the gold standard for measuring total, lean and bone tissue. Body weight alone is not a clear indicator of good health because it does not distinguish how many pounds are from fat and how many are from lean body mass.
BMI is just one indicator of being over weight or obese. BMI is a combination of your height and weight. An adult who has a BMI between 25 and 29.9 is considered overweight. An adult who has a BMI of 30 or higher is considered obese.
Body composition measurement with DEXA can look beyond weight and traditional body mass index (BMI) to determine body fat distribution ? an important risk factor in a variety of serious diseases.
