Frequently Asked Questions
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. It's calculated as weight (kg) divided by height (m) squared. BMI is a screening tool, not a diagnostic measure of body fatness or health.
Is BMI accurate for everyone?▼
BMI is a general screening tool but has limitations. It doesn't account for muscle mass, bone density, or body composition. Athletes may have high BMI despite low body fat. Consult a healthcare provider for personalized assessment.
What should I do if my BMI is in the obese category?▼
If your BMI indicates obesity, consult a healthcare provider for personalized guidance. They can assess your overall health, discuss lifestyle changes, and recommend appropriate interventions if needed.
Can BMI be used for children?▼
BMI can be used for children and teens, but the interpretation differs from adults. Children's BMI is age and sex-specific. Consult a pediatrician for proper assessment of children's weight status.
How often should I check my BMI?▼
For most people, checking BMI every 3-6 months is reasonable if monitoring weight changes. However, BMI is just one health indicator. Focus on overall health habits like exercise, nutrition, and regular medical checkups.
