BMI Formula
Metric Formula
BMI = weight (kg) / (height (m))²
Imperial Formula
BMI = (weight (lb) / height² (in²)) × 703
Example: A woman weighing 68 kg and 1.6 meters tall
BMI = 68 / (1.6 × 1.6) = 26.56
This result falls in the overweight category.

Why BMI Matters After 50
After age 50, hormonal changes, muscle loss, and slower metabolism affect how your body stores fat. Keeping your BMI within a healthy range can help lower the risk of heart disease, diabetes, and joint problems. However, BMI should be used along with other health metrics like waist circumference or body fat percentage.
