Understanding Body Weight and Health Risks

How can body composition be accurately assessed in a clinical setting, and what are the limitations of these methods?

• Using Body Mass Index (BMI) as it provides detailed information about muscle and fat distribution.

• Using Dual-Energy X-ray Absorptiometry (DEXA) scans, which provide detailed information about bone density, fat, and muscle mass.

• Using skinfold measurements, which are highly accurate and do not require skilled technicians.

• Using bioelectrical impedance analysis, which is unaffected by hydration levels.
