Frequently Asked Questions
What is a healthy BMI?
For adults, a BMI of 18.5–24.9 is considered healthy. Under 18.5 is underweight, 25–29.9 is overweight, and 30 or above is classified as obese.
Is BMI accurate?
BMI is a useful screening tool but not a complete measure of health. It doesn't account for muscle mass, bone density, age or distribution of fat. Athletes with high muscle mass often show high BMI despite being very fit.
Is BMI the same for men and women?
The same scale is used for both, but the interpretation can differ. Women naturally carry more body fat than men at the same BMI.
What BMI is considered obese?
A BMI of 30 or above is classified as obese. 35+ is severely obese. 40+ is morbidly obese.
