Frequently Asked Questions
What is BMI?
BMI (Body Mass Index) is a measure of body fat based on your weight in relation to your height. It provides a general indicator of whether a person has a healthy body weight.
Is BMI accurate for everyone?
While BMI is a useful screening tool, it doesn't directly measure body fat. It may not be accurate for athletes with high muscle mass, pregnant women, or the elderly. Always consult a healthcare provider for a comprehensive health assessment.
How often should I check my BMI?
For most adults, checking your BMI once every few months is sufficient unless you're actively trying to lose or gain weight.
Can children use this BMI calculator?
This calculator is designed for adults. Children and teens require age and sex-specific percentile calculations for accurate BMI assessment.
