Calculate Your BMI
BMI is a measurement of a person's leanness or corpulence based on their height and weight.
| BMI Range | Category | Health Risk |
|---|---|---|
| Below 18.5 | Underweight | Possible nutritional deficiency and osteoporosis |
| 18.5 - 24.9 | Normal weight | Low risk (healthy range) |
| 25 - 29.9 | Overweight | Moderate risk of developing heart disease, high blood pressure, stroke, diabetes |
| 30 and Above | Obesity | High risk of developing heart disease, high blood pressure, stroke, diabetes |
Understanding BMI
Body Mass Index (BMI) is a simple calculation using a person's height and weight. The formula is BMI = kg/m² where kg is a person's weight in kilograms and m² is their height in meters squared.
While BMI is a useful screening tool, it does have limitations. It doesn't account for factors like muscle mass, bone density, overall body composition, and racial and sex differences. Athletes might have a high BMI due to increased muscle mass rather than body fat.
Limitations of BMI:
- Doesn't differentiate between muscle and fat
- Doesn't account for where fat is stored in the body
- May not be accurate for elderly individuals who have lost muscle mass
- May not be suitable for pregnant or breastfeeding women
Note: BMI is a screening tool, not a diagnostic tool. Always consult with a healthcare professional for a comprehensive health assessment.
