Calculate Your BMI

Understanding BMI

BMI is calculated using your weight and height. It provides an estimate of whether you are underweight, normal weight, overweight, or obese. While it does not measure body fat directly, BMI is a reliable screening tool for adults and population-level studies.

How to Calculate BMI

Use the following formulas:

Metric: BMI = weight (kg) ÷ height² (m²)
Imperial: BMI = (weight (lb) ÷ height² (in²)) × 703

BMI Categories for Adults

Underweight: BMI < 18.5
Normal weight: BMI 18.5 – 24.9
Overweight: BMI 25 – 29.9
Obese: BMI ≥ 30

Why BMI Matters

A high BMI increases the risk of heart disease, diabetes, hypertension, and joint problems. A low BMI may indicate malnutrition or other health issues. Monitoring BMI helps you make informed health decisions and maintain wellness.

Gender and Age Considerations

BMI interpretation varies by sex and age. Women naturally have a higher body fat percentage. Children use BMI percentiles to account for growth. Seniors may have slightly different ranges due to muscle and bone mass changes.

Tips to Maintain a Healthy BMI

Eat a balanced diet rich in fruits, vegetables, lean protein, and whole grains.
Exercise regularly, including strength and cardio training.
Monitor BMI periodically to track progress.
Consult a healthcare provider for personalized guidance.
