Frequently Asked Questions
1. What is a healthy BMI range?
For adults:
- Underweight: Below 18.5
- Normal: 18.5 - 24.9
- Overweight: 25 - 29.9
- Obese: 30 and above
2. Does BMI work for athletes or muscular people?
No, BMI may overestimate fat in muscular people (since muscle weighs more than fat). Other tests (like body fat %) may be better.
3. Is BMI different for men and women?
The same BMI ranges apply, but women naturally have more body fat than men at the same BMI.
4. Can children use this BMI calculator?
No, this is for adults only. Children’s BMI is measured differently (using age and growth charts).
5. How often should I check my BMI?
Every 3–6 months if you’re tracking weight changes.
6. What if my BMI is high?
Consult a doctor or nutritionist. Small changes (like eating healthier or exercising) can help.
7. What if my BMI is low?
If you’re underweight, focus on nutrient-rich foods and strength training.
8. Does BMI tell my body fat percentage?
No, BMI only estimates weight vs. height. For body fat %, use special scales or tests.
9. Why does BMI matter?
High BMI increases risks for diabetes, heart disease, and joint problems. Low BMI may mean weak immunity or malnutrition.
10. What’s better than BMI?
Waist-to-hip ratio, body fat %, or doctor’s advice give more accurate health insights.
