🔎 What Is BMI?
Body Mass Index (BMI) is a number calculated by dividing your weight (kg) by your height in meters squared (m²).
- Formula: BMI = weight (kg) ÷ height² (m²)
- Example: If you weigh 70 kg and are 1.75 m tall → BMI = 70 ÷ (1.75 × 1.75) = 22.9
📊 Healthy BMI Ranges (Adults)
According to the World Health Organization (WHO):
| BMI Range | Category | Health Status |
|---|---|---|
| Below 18.5 | Underweight | Risk of nutritional problems |
| 18.5 – 24.9 | Normal weight | Healthy range |
| 25 – 29.9 | Overweight | Increased health risks |
| 30 & above | Obese | Higher risk of chronic disease |
✅ A healthy BMI for most adults is 18.5 to 24.9.
⚖️ BMI for Men vs Women
The calculation is the same for both men and women. However, women may naturally have higher body fat at the same BMI compared to men.
👶 BMI by Age (Teens, Adults, Seniors)
- Children & Teens (2–19 years) → BMI is compared to age & sex percentiles.
- Adults (20–65 years) → Standard WHO chart applies.
- Seniors (65+) → Slightly higher BMI may still be considered healthy due to natural muscle loss with age.
⚠️ Limitations of BMI
While BMI is useful for population studies, it has some limitations:
- Doesn’t measure muscle mass vs body fat
- May misclassify athletes or muscular individuals
- Doesn’t consider body shape or fat distribution
