About BMI
Body Mass Index (BMI) is a measure of body fat based on height and weight. It's used to screen for weight categories that may lead to health problems.
BMI Categories:
- Underweight: BMI less than 18.5
- Normal weight: BMI 18.5 to 24.9
- Overweight: BMI 25 to 29.9
- Obese: BMI 30 or greater
Note: BMI is not a diagnostic tool. It doesn't account for muscle mass, bone density, or overall body composition. Consult with a healthcare professional for a comprehensive health assessment.
Frequently Asked Questions
What is BMI and how is it calculated?
BMI (Body Mass Index) is calculated by dividing your weight in kilograms by your height in meters squared. The formula is: BMI = weight(kg) / height(m)²
What is a healthy BMI range?
According to WHO guidelines, a healthy BMI range is 18.5 to 24.9. Below 18.5 is underweight, 25-29.9 is overweight, and 30 or above is obese.
Is BMI accurate for everyone?
BMI is a general screening tool but doesn't account for muscle mass, bone density, or body composition. Athletes with high muscle mass may have higher BMI despite being healthy.
Should I use BMI for medical decisions?
BMI is not a diagnostic tool. Always consult with a healthcare professional for comprehensive health assessments and medical decisions.
