Frequently asked questions
What is a healthy BMI?
A BMI between 18.5 and 24.9 is generally considered healthy. Below 18.5 is underweight, 25–29.9 is overweight and 30 or above is obese.
Is BMI accurate for athletes?
Not always. BMI does not distinguish muscle from fat, so very muscular people can have a high BMI while being healthy.
