⚙️ How It Works
Body Mass Index (BMI) is a screening tool that estimates body fat based on height and weight. It divides your weight in kilograms by the square of your height in meters. While BMI is widely used, it doesn't directly measure body fat and doesn't account for muscle mass, bone density, or fat distribution.
BMI is a screening tool for body-size categories. It does not directly measure body fat or overall health.
Use these numbers as screening estimates, not as a diagnosis.
Age, sex, activity, medications, and medical conditions can change the right interpretation.
If you are pregnant, symptomatic, or managing a condition, confirm decisions with a licensed clinician.
❓ FAQ
What is a healthy BMI range?
For adults, a BMI of 18.5–24.9 is considered normal weight. Below 18.5 is underweight, 25–29.9 is overweight, and 30 or above is obese. These thresholds may differ for certain ethnic groups.
Is BMI accurate for athletes?
BMI can overestimate body fat in athletes and muscular individuals because muscle weighs more than fat. A bodybuilder may have a high BMI while having very low body fat. Use additional measures like waist circumference for a fuller picture.
Does BMI apply to children?
For children and teens (ages 2–19), BMI is interpreted using age- and sex-specific percentile charts, not the adult thresholds. A pediatrician should interpret BMI results for children.
What are the health risks of high BMI?
Higher BMI is associated with increased risk of type 2 diabetes, heart disease, high blood pressure, sleep apnea, and certain cancers. Even modest weight loss (5–10%) can significantly reduce these risks.
