What is BMI?

BMI (Body Mass Index) is a simple calculation using your height and weight to estimate your body fat. It’s a quick and easy method to understand whether you’re underweight, at a healthy weight, overweight, or obese.

How to Calculate BMI

The formula to calculate BMI is:

• Metric: BMI = weight (kg) ÷ height (m²)

For example, someone who weighs 70 kg and is 175 cm tall would have a BMI of:
BMI = 70 / (1.75 × 1.75) = 22.86

BMI Categories (According to WHO)

• Underweight: BMI less than 18.5
• Normal weight: 18.5 – 24.9
• Overweight: 25 – 29.9
• Obese: 30 or more

Why is BMI Important?

Tracking your BMI helps you stay aware of your health risks related to weight. A high BMI may be associated with increased risk of heart disease, diabetes, and other health issues.

Limitations of BMI

While BMI is a helpful screening tool, it does not measure body fat directly or account for muscle mass. Athletes and those with high muscle mass may fall into the “overweight” category despite being healthy.
