Body Composition
Beyond the scale number
A complete body composition picture
Stepping on a scale tells you one number. It does not tell you whether a two-kilogram gain is muscle from your training block or water retention from a high-sodium weekend. Omnio pulls body composition data from smart scales (body fat, muscle mass, BMI), DEXA scans (regional lean mass, bone density, visceral fat), and Garmin's body composition metrics to build a complete picture over time. Trend charts separate the signal from the noise, smoothing daily scale fluctuations while highlighting genuine changes in fat mass or lean tissue. When paired with training load and nutrition data, body composition trends gain context: you can see whether a cut is preserving muscle, whether a bulk is adding too much fat, or whether your bone density is responding to resistance training.
Composition tracking capabilities
Omnio's body composition features include:
- Smart scale integration via OpenScale: weight, body fat %, muscle mass, BMI
- DEXA scan import (BodySpec): regional lean mass, bone mineral density, visceral adipose tissue
- Garmin body composition metrics: skeletal muscle, body water, BMR estimates
- Trend smoothing to filter daily fluctuations and surface real changes
- Cross-referencing with training and nutrition data for recomposition tracking
- Face age estimation as an additional biological age signal
Frequently Asked Questions
- How often should I weigh in?
- Daily weigh-ins provide the best trend data. Omnio smooths the noise so you see the real trajectory, not the daily ups and downs.
- Do I need a DEXA scan?
- No. Smart scale data works well for tracking trends. DEXA adds precision for regional composition and bone density when available.
