Step 1 of 8
Determination of body composition is done in order to determine obesity and overweight, as well as to describe the changes in body composition more specifically. Body mass index (BMI) was previously used to determine overweight or obesity. However, BMI cannot clearly differentiate between individuals with heavy muscles and overfat. Since obesity is clearly associated with overfat and not muscles, methods that clearly differentiate between them are developed to determine overweight.
