Frequently asked questions

What is a healthy BMI?

For most adults, a BMI from 18.5 to 24.9 is considered healthy, 25 to 29.9 overweight, and 30 or more obese. BMI is a screening measure and does not account for muscle mass, so speak to a doctor for advice about your health.

How is BMI calculated?

BMI is your weight in kilograms divided by your height in metres squared. For example, 70 kg at 1.75 m is 70 รท (1.75 ร— 1.75) = 22.9.
