📘 About Ideal Body Weight (IBW)
IBW formulas estimate healthy weight based on height and gender, originally for medical dosage. Limitations: they ignore muscle mass, age, and body fat. Use as a reference. The four formulas are Robinson (1983), Miller (1983), Devine (1974), Hamwi (1964). The BMI range (18.5–25) is shown for comparison.
