Understanding Your BMI
What is BMI?
Body Mass Index (BMI) is a numerical value calculated from your weight and height. It provides a simple way to categorize individuals as underweight, normal weight, overweight, or obese.
Why is BMI Important?
BMI is a useful screening tool to identify potential weight problems in adults. While it doesn’t directly measure body fat, research has shown that BMI correlates with more direct measures of body fat.
Limitations of BMI
BMI has some limitations. It may overestimate body fat in athletes and others with muscular builds, and underestimate body fat in older persons and others who have lost muscle mass.
Next Steps
If your BMI falls outside the normal range, consider consulting with a healthcare provider. They may recommend additional assessments such as skinfold thickness measurements, diet evaluations, physical activity, family history, and other health screenings.
