BMI Explained Simply: How to Calculate & What It Means
Body Mass Index (BMI) is a quick estimate comparing your weight to your height. It’s not a medical diagnosis, but a simple indicator.
How to Calculate BMI
BMI = weight (kg) / [height (m)]²
Example: 68 kg and 1.70 m → 68 / (1.7 × 1.7) = 23.53

What the Number Means

- 30+ — Obese
Remember: BMI doesn’t account for muscle mass or medical conditions. Use it as a starting point, not a final verdict.
