The photo above shows roughly what 51% body fat looks like on a woman. But your body is your own. Frame, muscle, and where you store fat all change how a given body fat percentage actually looks.
FitCommit's AI Body Scan uses three phone photos to estimate your body fat and lean mass. After Photo creates a motivational preview of what progress could look like at 3, 6, or 12 months. It is not a guaranteed outcome.

How We Estimate Body Fat (and Its Limits)
The photo and ranges on this page show a typical presentation of 51% body fat. Real appearance varies with frame size, muscle mass, where you store fat, age, and lighting, so two people at 51% can look different. The percentage itself is an estimate: home methods like the U.S. Navy circumference formula are typically accurate to within 3 to 4 points, while DEXA and hydrostatic weighing are more precise but require a clinic. The consumer bioimpedance (BIA) scales most people own are the least reliable of all, often swinging several points with hydration alone, which is why a photo-based estimate is usually a more consistent way to track change over time.
These guides are educational, not a medical diagnosis or a substitute for assessment by a qualified professional. Our figures and methodology are reviewed by Andrew Menechian, Head of Fitness; see the full body composition methodology for formulas and sources.
