Body Mass Index (BMI) is one of the most widely used methods to assess whether a person has a healthy body weight in relation to their height. Doctors, fitness experts, and health organizations across the world use BMI as a quick screening tool to identify potential weight-related health risks.

What Is Body Mass Index?

BMI is a numerical value calculated using your weight and height. It helps categorize individuals into groups such as underweight, normal weight, overweight, or obese. While BMI does not directly measure body fat, it provides a reliable indicator for most adults.

The basic BMI formula is:

BMI = weight (kg) ÷ height² (m²)

Why Is BMI Important?

Maintaining a healthy BMI range is associated with lower risks of several health conditions, including:

• Heart disease

• Type 2 diabetes

• High blood pressure

• Joint problems

• Certain metabolic disorders

BMI is often used as a starting point, helping people decide whether they should take further steps toward improving their lifestyle.

BMI Categories Explained

According to standard guidelines:

• Underweight: BMI below 18.5

• Normal weight: BMI between 18.5 and 24.9

• Overweight: BMI between 25 and 29.9

• Obese: BMI 30 or higher

These categories apply to most adults, regardless of gender.

Limitations of BMI

Although BMI is helpful, it does have limitations:

• It does not distinguish between fat and muscle

• Athletes may have a high BMI despite low body fat

• It may not fully account for age or body composition

That’s why BMI should be used alongside other health indicators, such as waist circumference, body fat percentage, and overall fitness levels.

Final Thoughts

Body Mass Index remains a simple and effective first step in understanding your overall health status. If your BMI falls outside the normal range, it can be a helpful signal to reassess your diet, activity level, and lifestyle choices.

Using trusted tools and interpreting BMI correctly can guide you toward healthier decisions—without overcomplicating the process.
