Body fat vs. weight
Two people at the same weight can look radically different — muscle is denser than fat. Body-fat percentage captures composition, not just mass. The US Navy method used here is a tape-measure estimate; DEXA scans and hydrostatic weighing are more accurate but rarely available at home.

Cross-reference with the BMI Calculator — if BMI says overweight but body fat is low, muscle is skewing the reading. Use the TDEE Calculator to set calorie targets for composition change.
