How We Estimate Body Fat (and Its Limits)

The photo and ranges on this page show a typical presentation of 50% body fat. Real appearance varies with frame size, muscle mass, where you store fat, age, and lighting, so two people at 50% 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.
