Ideal body weight is an estimate, not a target. The four formulas (Devine, Robinson, Miller, Hamwi) were derived for clinical dosing references and differ by a few kilograms. The healthy BMI range is the World Health Organization classification (18.5 to 24.9). For educational use; a clinician accounts for body composition, frame, and individual context.
