Questions

What is a healthy BMI?

For adults the World Health Organization classes 18.5–24.9 as a healthy weight, 25–29.9 as overweight and 30 or above as obesity.

Is BMI accurate for everyone?

BMI is a screening measure. It doesn’t distinguish muscle from fat and isn’t meant for children, pregnant people or athletes. Talk to a doctor for health advice.
