Does BMI alone fully reflect my health status?

No. BMI doesn't distinguish between muscle and fat; for example, an athlete with high muscle mass might come out as "overweight" by BMI despite having low body fat. That's why BMI should be treated as a general indicator, not a standalone measure.

How are the BMI categories determined?

These ranges are the standard thresholds set by the World Health Organization for adults: below 18.5 is underweight, 18.5-24.9 is normal, 25-29.9 is overweight, and 30 or above is obese.

Can this be used for children?

No, this calculator is designed for adults. For children and teenagers, BMI is assessed using age- and gender-specific percentile charts, which this tool isn't suited for.

Is the result medical advice?

No, this tool is for general informational purposes only and isn't a substitute for medical advice. If you have concerns about your weight or health, you should consult a doctor.
