About ideal body weight formulas
No single formula definitively defines an "ideal" weight — these are statistical estimates developed for clinical use (particularly for medication dosing). Each was derived from different populations, which is why they give slightly different results.
The average of multiple formulas gives a more reliable range than any single estimate. Your healthy weight also depends on muscle mass, bone density, and individual health history — which no formula can capture.
Not medical advice. Ideal weight calculations are general estimates. Consult a healthcare provider for personalised weight management guidance.
