What is BMI?
BMI (Body Mass Index) is a simple calculation using a person's height and weight. It's used to categorize whether a person has a healthy body weight for their height.
Common Questions
Is BMI accurate for everyone?
BMI is a general screening tool and doesn't account for muscle mass, bone density, or fat distribution. Athletes may have higher BMIs due to muscle, not fat.
What is a healthy BMI range?
A healthy BMI typically falls between 18.5 and 24.9. Below 18.5 is underweight, 25-29.9 is overweight, and 30+ is considered obese.
Should children use BMI?
For children and teens, BMI is interpreted differently using age and gender-specific percentiles. Consult a pediatrician for accurate assessment.
How often should I check my BMI?
Checking your BMI once every few months is sufficient for most adults. Focus on maintaining a healthy lifestyle rather than frequent weighing.
