Understanding BMI: Calculation, Interpretation & What It Means for Your Health

BMI (Body Mass Index) is calculated by dividing a person's weight in kilograms by the square of their height in meters.

Here's the formula:

BMI = Weight in Kilograms / (Height in Meters)2

For example, if someone weighs 75 kilograms and is 1.75 meters tall, their BMI would be calculated as:

BMI = 75 kg / (1.75 m)2 = 24.2

The interpretation of BMI values may vary depending on age, sex, ethnicity, and other factors. Generally, BMI is categorized as follows:

- Underweight - BMI less than 18.5

- Normal weight - BMI between 18.5 and 24.9

- Overweight - BMI between 25 and 29.9

- Obese (class I) - BMI between 30 and 34.9

- Obese (class II) - BMI between 35 and 39.9

- Obese (class III) - BMI 40 or higher
