// FAQ
Good to know
Why do the formulas disagree?+
Each was developed on a different population, decades apart, mostly to estimate drug dosing rather than define a health target. Use them as a rough band, not a precise goal.
Which number should I actually aim for?+
For most people the healthy-BMI range is the more clinically meaningful target — a physician can help you set a specific, individualised goal based on your full health picture.
