Understanding BMI (Body Mass Index)
What is BMI?
Body Mass Index (BMI) is a measure of body fat based on height and weight. It's used as a screening tool to identify whether a person is underweight, normal weight, overweight, or obese.
BMI Categories
- Underweight: BMI less than 18.5
- Normal weight: BMI 18.5 to 24.9
- Overweight: BMI 25 to 29.9
- Obese: BMI 30 or greater
Important Note
While BMI is a useful screening tool, it has limitations. It doesn't directly measure body fat and may not accurately reflect health for athletes, elderly individuals, or certain ethnic groups. Always consult with a healthcare provider for personalized health assessments.
