Body Mass Index (BMI) is a measure that estimates body fat content based on height and weight.
While BMI is a widely used metric for assessing body weight status, its accuracy in determining body fat content can vary greatly. Another method, bioelectrical impedance analysis (BIA), uses electrical signals to estimate body fat content. BIA devices are often used in fitness centers and medical settings. BIA has the potential to provide a more accurate assessment of body fat content than BMI, as it takes into account factors such as muscle mass and hydration. However, BIA can be affected by factors such as hydration status and the type of BIA device used.
