What Is BMI (Body Mass Index)?
BMI stands for Body Mass Index, a simple calculation that helps determine whether your weight is healthy according to your height. It’s one of the most widely used methods for assessing body fat levels in adults. The BMI value is calculated using the formula:
BMI = Weight (kg) / Height² (m²)
This result classifies your body weight into categories such as underweight, normal weight, overweight, or obese.
Why Is BMI Important?
Your BMI score gives a quick overview of your health status. While it doesn’t measure body fat directly, it provides a useful guideline to understand potential health risks.
-
- Underweight (BMI < 18.5): May indicate malnutrition or low body fat.
-
- Normal weight (BMI 18.5 – 24.9): Ideal and healthy range.
-
- Overweight (BMI 25 – 29.9): May lead to health issues if not managed.
-
- Obese (BMI ≥ 30): High risk of diabetes, heart disease, and other health conditions.
Knowing your BMI helps you make better lifestyle and dietary decisions.

Limitations of BMI
While BMI is a helpful health indicator, it doesn’t account for muscle mass, age, or gender differences. For example, athletes with high muscle mass might have a high BMI but low body fat. Therefore, use BMI as a general guide, not a final diagnosis.
