Frequently Asked Questions
How accurate are IBW formulas?
Formulas like Devine and Robinson provide a good baseline for the “average” person but do not account for muscle mass, bone density, or age. Athletes often weigh more than their “Ideal Body Weight” due to muscle, which is healthy. Always consider the BMI range as a broader, more inclusive guide.
Why do different formulas give different results?
They were developed in different years using different population data. Devine (1974) is standard for pharmacology. Robinson (1983) and Miller (1983) adjusted for refined population statistics of their time.
