IBW formulas are clinical tools originally designed for medication dosing, not aesthetic or athletic goals. Muscle mass and body composition are not accounted for.
Frequently Asked Questions
Which IBW formula is most accurate?
The Peterson formula (2016) is the most recently validated and accounts for height more proportionally. Robinson (1983) is the most widely used in clinical settings.
Should I aim for my IBW?
IBW is a clinical reference, not a fitness goal. Athletes and muscular individuals may healthily exceed IBW. Focus on body fat percentage and functional fitness.
