Body measurements
BMI, body fat, lean mass and ideal weight.
Each of these has more than one accepted formula and they disagree, sometimes by a lot. Every page names the one it used.
- BMI Body mass index, the band it falls in, and the healthy weight range for your height.
- BMR What your body spends doing nothing, and what activity adds to it.
- Body fat Body fat from a tape measure, using the US Navy method.
- Ideal weight Four published formulas, and how far apart they are.
- Lean body mass Everything that is not fat, by three formulas or from a measured percentage.
- Waist to height The measure that beats BMI, and needs one number BMI ignores.
