Frequently Asked Questions

How do I know if my BMI is healthy?
A BMI between 18.5 and 24.9 is considered healthy by the WHO. The calculator color-codes your result: green for healthy, blue for underweight, yellow for overweight, and shades of red for obese. But BMI is a screening tool — if you have concerns, consult a healthcare provider.
My BMI says I'm overweight but I feel healthy. Is that possible?
Yes. BMI doesn't account for muscle mass, bone density, or fat distribution. If you exercise regularly, have good metabolic markers (blood pressure, blood sugar, cholesterol), and carry weight as muscle rather than visceral fat, you may be healthier than your BMI suggests.
What should I do if my BMI is not healthy?
Don't panic — BMI is a starting point, not a verdict. For overweight/obese BMI: consider sustainable dietary changes and increased physical activity. For underweight BMI: ensure adequate nutrition and consult a doctor to rule out underlying causes. In all cases, your healthcare provider can give personalized advice.

Medical disclaimer: BMI is a screening tool, not a medical diagnosis. It does not measure body fat directly and does not account for muscle mass, bone density, age, sex, or ethnicity. Consult a healthcare provider for personalized health advice.
