Frequently asked questions
Which formula is best?
Devine is the most widely cited. All of them are population averages; individual healthy weight also depends on muscle mass and body composition.
Is ideal weight the same as healthy BMI?
They correlate but are not identical. BMI 18.5–24.9 is the usual healthy range; ideal-weight formulas give a single target.
Do athletes need a different target?
Yes. Highly muscular people often sit above formula “ideal” weight while remaining healthy.
Should I aim exactly for this number?
Treat it as a reference range, not a strict goal. Focus on sustainable habits and how you feel.
