FAQ

What does “healthy range” mean?
It’s the weight range corresponding to BMI 18.5–24.9 for your height. It’s a screening tool, not a diagnosis.
What is the Devine formula?
A clinical estimate of ideal body weight based on height: men 50 kg + 2.3 kg/in over 5 ft; women 45.5 kg + 2.3 kg/in over 5 ft.
Which should I use?
Use the range to see a span of healthy weights; Devine is one point estimate often used for dosing/clinical contexts.
