Frequently asked questions
Which formulas does it use?
Four classic formulas — Devine, Robinson, Miller and Hamwi — based on height and sex.
Why do the results differ?
Each formula was derived differently, so together they give a range rather than a single correct number.
Is one ideal weight realistic?
Not really — healthy weight is a range that depends on build, muscle and health, so treat these as guidelines.
