Frequently Asked Questions
What is ideal body weight (IBW)?↓
IBW is a clinically derived estimate of the healthiest weight for a given height and sex. It was originally developed for drug dosing in hospitals, not as a fitness target. Several different formulas exist (Devine, Robinson, Miller, Hamwi) and their results differ slightly.
Which IBW formula is most accurate?↓
No single formula is universally best. Devine (1974) is most commonly used in clinical settings. Miller and Robinson (1983) are refinements. The BMI-based healthy range (18.5–24.9) is the most widely accepted standard for general population use.
What is IBW for a 5'10 male?↓
Using the Devine formula: IBW = 50 + 2.3 × (70 − 60) = 50 + 23 = 73 kg (160.9 lbs). The healthy BMI range for 5'10 is approximately 58–78 kg (128–172 lbs).
Should I aim to reach my IBW?↓
IBW formulas give a rough estimate and don't account for muscle mass, body composition, or individual variation. Use it as a rough benchmark alongside BMI, body fat percentage, and guidance from a healthcare professional.
