Body Mass Index (BMI) is a widely used screening method to categorize weight. While it is not a perfect diagnostic of the health of an individual, it provides a useful snapshot for the general population.
What is BMI?
BMI is a simple calculation using a person's height and weight. The formula is: BMI = kg / m².
It helps categorize individuals into groups:
- Underweight: BMI less than 18.5
- Normal weight: BMI 18.5 to 24.9
- Overweight: BMI 25 to 29.9
- Obesity: BMI 30 or greater
Limitations to Keep in Mind
BMI does not distinguish between fat and muscle. A professional athlete might have a high BMI because muscle is dense, yet have very low body fat. Conversely, an elderly person might have a normal BMI but low muscle mass.
Always use BMI as a starting point, not a final diagnosis. Consult a doctor for a full health assessment.
