Understanding Your BMI Results
Body Mass Index (BMI) is a widely used screening method for weight category—underweight, healthy weight, overweight, and obesity. While BMI does not measure body fat directly, it correlates moderately with more direct measures of body fat.
BMI Categories for Adults
- Underweight: BMI less than 18.5
- Healthy Weight: BMI 18.5 to 24.9
- Overweight: BMI 25.0 to 29.9
- Obesity: BMI 30.0 and higher
Why BMI Matters
A high BMI can be an indicator of high body fatness. Having excess body fat can lead to serious health conditions like heart disease, type 2 diabetes, and high blood pressure.
Frequently Asked Questions
How is BMI calculated?
BMI is calculated by dividing an adult's weight in kilograms by their height in meters squared. The formula is BMI = kg/m2.
Is BMI accurate for everyone?
BMI may overestimate body fat in athletes and others who have a muscular build. It may also underestimate body fat in older persons and others who have lost muscle mass.
What is a healthy BMI for women?
The healthy BMI range for women is generally the same as for men: 18.5 to 24.9. However, women naturally tend to have more body fat than men at the same BMI.
