Frequently Asked Questions
- What is a healthy BMI range?
- For most adults, 18.5–24.9 is considered a healthy weight, 25–29.9 is overweight and 30 or above is obese. Below 18.5 is underweight.
- What is the BMI formula?
- Metric: weight in kilograms divided by height in metres squared. Imperial: weight in pounds divided by height in inches squared, multiplied by 703.
- Is BMI accurate for everyone?
- No. BMI does not distinguish muscle from fat, so athletes often read as overweight. It is a screening tool, not a diagnosis.
