- ⚠ BIA (bioelectrical impedance) body fat measurements can vary by 3-5% based on hydration, meal timing, and time of day; use trends, not individual readings.
- ⚠ Bioelectrical impedance measurements should not be used by individuals with pacemakers or other implanted medical devices.
- ⚠ Bioelectrical impedance measurements require bare feet on the metal sensors; socks or shoes will prevent accurate body composition readings.
