Body Fat Estimator

Rate My Physique estimates your body fat percentage from a single photo so you can track composition without calipers or scales.

Rate My Physique estimates your body fat percentage from a single photo so you can track composition without calipers or scales.

  1. Take or upload a photo
    Use the in-app camera or pick a photo from your camera roll. A well-lit, full-body shot works best.

  2. Run the scan
    The AI analyzes muscle definition, shape, and visible composition cues in the photo.

  3. Review your estimate
    Your body fat estimate is shown alongside your physique score, so you can see composition and overall rating in one place.

  4. Track it over time
    Every scan is saved. Watch your body fat estimate change as you cut, bulk, or maintain.

  • Scan at the same time of day, ideally in the morning before eating.
  • Avoid heavy shadows, filters, or edited photos.
  • Keep your posture consistent from one scan to the next.

A body fat estimate is a directional read on your composition, not a clinical measurement. Use it to spot trends over weeks and months rather than obsessing over a single reading.
