Formulas used

There are multiple scientific formulas for estimating "ideal" body weight based on height and sex. We provide calculations from the two most widely referenced methodologies:

Devine (1974): Men: 50 + 2.3 × (in − 60); Women: 45.5 + 2.3 × (in − 60).
Robinson (1983): Men: 52 + 1.9 × (in − 60); Women: 49 + 1.7 × (in − 60).

These formulas are strictly estimations and do not account for muscle mass or overall body composition.
