How BMI is Calculated
The formula for BMI is:
BMI = Weight (kg) ÷ Height (m)2
For example, a person weighing 70 kg with a height of 1.75 m would have a BMI of 22.9, which falls in the normal weight range.
BMI Categories
| BMI Range | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5 – 24.9 | Normal Weight |
| 25 – 29.9 | Overweight |
| 30 and above | Obese |
Why BMI is Useful

✔ Helps doctors identify health risks

Limitations of BMI
While BMI is useful, it doesn’t consider muscle mass, body fat percentage, or distribution of fat. Athletes may have a high BMI due to muscle weight but still be perfectly healthy.
