Frequently asked questions

What do the BMI numbers mean?

BMI is weight divided by height squared. The WHO bands are under 18.5 underweight, 18.5 to 24.9 healthy, 25 to 29.9 overweight, and 30 or more obese.

What is the healthy weight range shown?

It is the weight range that keeps your BMI between 18.5 and 24.9 for the height you entered, calculated with the same formula in reverse.

Is BMI a medical diagnosis?

No. BMI is a screening tool and does not measure body fat or fitness. Talk to a doctor for real health advice.
