Understanding BMI
What is BMI?
Body Mass Index (BMI) is a measure of body fat based on height and weight that applies to adult men and women.
Health Indicator
BMI is a reliable indicator of body fatness for most people and is used to screen for weight categories.
Limitations
BMI may overestimate body fat in athletes and underestimate it in older persons with lost muscle mass.
BMI FAQs
What is a healthy BMI range?
A healthy BMI range for adults is between 18.5 and 24.9. This range is associated with the lowest health risks.
Is BMI accurate for everyone?
BMI is a useful screening tool but doesn't account for muscle mass, bone density, or body composition. Athletes and elderly individuals may get misleading results.
How often should I check my BMI?
For most adults, checking BMI every 3-6 months is sufficient unless you're actively trying to lose or gain weight.
Can children use this calculator?
This calculator is designed for adults (20+ years). Children and teens require age and gender-specific BMI percentiles.
What's the difference between BMI and body fat percentage?
BMI estimates body fat based on height and weight, while body fat percentage directly measures fat mass. Body fat percentage is more accurate but harder to measure.
