Frequently asked questions
Why is the healthy range so wide?
People differ in frame size and muscle mass, so a range of several kilograms is considered healthy for any given height.
Should older adults aim for the same range?
Older adults often do better at the upper end of the range. Talk with a clinician about a target that fits your health.
How is the healthy weight range calculated?
It multiplies the healthy BMI limits by your height in metres squared. For 1.70 m, BMI 18.5 to 24.9 gives about 53.5 to 72 kg with the WHO cut-offs.
