Frequently Asked Questions

Not exactly \u2014 the Devine formula was originally created to help calculate medication dosages, not as a general wellness target. It's widely cited as a reference point, but doesn't account for body composition, muscle mass, or frame size the way a fuller health assessment would.
For men: 50 kg + 2.3 kg for each inch over 5 feet. For women: 45.5 kg + 2.3 kg for each inch over 5 feet. Height exactly at 5 feet gives the base value with no addition.
