The Ultimate Guide to Body Mass Index (BMI)

BMI is a simple mathematical formula: your weight in kilograms divided by the square of your height in meters.
Featured Snippet Answer:
How do I calculate my BMI? To calculate it manually, use the formula: Weight (kg) ÷ (Height (m) × Height (m)). For adults, a healthy range is between 18.5 and 24.9.
BMI Classification Table (WHO Standards)
| Weight Category | BMI Range | Health Risk | | :--- | :--- | :--- | | Underweight | < 18.5 | High | | Normal Weight | 18.5 – 24.9 | Minimal | | Overweight | 25.0 – 29.9 | Moderate | | Obese (Class I) | 30.0 – 34.9 | High | | Morbidly Obese | > 35.0 | Very High |
Limitations: When is BMI Misleading?
- Muscle Mass: Athletes may score as "Obese" because muscle is denser than fat.
- Fat Distribution: It doesn't distinguish between visceral fat and subcutaneous fat.
- Elderly: Body composition changes with age.
Conclusion
BMI is a great tool for a general health overview.
