Maintaining a healthy weight is an important part of overall wellness.

What is BMI?

Body Mass Index (BMI) is a measurement that compares your weight to your height to determine if you are at a healthy weight. It is calculated using a simple formula:

BMI = Weight (kg) ÷ Height (m²)

The World Health Organization (WHO) and medical professionals use BMI as a standard indicator of body fatness and overall health risk.

BMI Categories

The result of your BMI calculation falls into one of the following categories:

  • Underweight: BMI less than 18.5
  • Normal weight: BMI 18.5 – 24.9

Limitations of BMI

While BMI is a useful guideline, it is not a perfect measure. It does not distinguish between fat and muscle, and may not apply accurately to athletes, children, or elderly individuals.
