Understanding Your BMI
What is BMI?
Body Mass Index (BMI) is a value derived from a person's weight and height. It provides a simple numeric measure of a person's thickness or thinness, allowing health professionals to discuss weight problems more objectively with their patients.
BMI Categories
- Below 18.5: Underweight
- 18.5 - 24.9: Normal weight
- 25.0 - 29.9: Overweight
- 30.0 and above: Obese
Limitations of BMI
While BMI is useful for most people, it does have limitations:
- It may overestimate body fat in athletes and others with muscular builds
- It may underestimate body fat in older persons and those who have lost muscle mass
- It doesn't account for differences in body composition between genders
- It doesn't distinguish between fat, muscle, and bone
For a complete assessment of your health, consult with a healthcare professional.
