Limitations and Tips
- This is an estimate; for precise measurements, consult a professional (e.g., DEXA scan).
- Measure consistently (e.g., same time of day, relaxed muscles).
- Track changes over time rather than absolute values.
- For best results, combine with other health metrics like BMI or waist-to-hip ratio.
