# BMI Calculator: How to Calculate Your Body Mass Index
BMI is a simple number that tells you if your weight is healthy for your height. Here's how to calculate it and what it means.
What Is BMI?
BMI = Weight (kg) / Height (m)²
Example: - Weight: 70 kg - Height: 1.75 m - BMI = 70 / (1.75 × 1.75) = 22.9
BMI Categories
| BMI Range | Category |
|-----------|----------|
| Below 18.5 | Underweight |
| 18.5 - 24.9 | Normal weight |
| 25.0 - 29.9 | Overweight |
| 30.0 - 34.9 | Obese (Class I) |
| 35.0 - 39.9 | Obese (Class II) |

Is BMI Accurate?
BMI is useful but not perfect:
Limitations:
- Doesn't distinguish muscle from fat
- Athletes may appear "overweight"
- Doesn't account for body fat distribution
- May differ for different ethnicities
Better metrics to combine with BMI:
- Waist circumference
- Body fat percentage
- Blood pressure
- Cholesterol levels
How to Improve BMI
If Underweight: - Increase calorie intake - Eat nutrient-dense foods - Add strength training
If Overweight: - Create a calorie deficit - Increase physical activity - Reduce processed foods
