Is 73% body fat possible? What the science and historical records say
Health Notice
No named individual has been formally measured at 70% body fat. This level is theoretically possible but represents extreme morbid obesity with severely limited mobility.

The photo above shows roughly what 73% 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 reads a photo from your phone to estimate your real body fat percentage, then previews your future physique at your target. You see your own transformation before you start, not a stock body.

The photo and ranges on this page show a typical presentation of 73% body fat. Real appearance varies with frame size, muscle mass, where you store fat, age, and lighting, so two people at 73% 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.
