Frequently asked questions
What is a healthy BMI?
A BMI of 18.5 to 24.9 is considered healthy for most adults. Below 18.5 is underweight, 25-29.9 is overweight, and 30+ is obese.
Is BMI accurate for everyone?
BMI is a general screening tool, not a diagnostic measure. It doesn't account for muscle mass, bone density, age or gender differences. Athletes may have high BMI with low body fat.
What is BMI Prime?
BMI Prime is your BMI divided by 25 (the upper limit of normal). A value of 1.0 means exactly at the upper normal limit. Below 1.0 is normal, above 1.0 is overweight.
