📖 What is BMI?
Body Mass Index (BMI) is a simple calculation using a person's height and weight. The formula is BMI = kg/m² where kg is a person's weight in kilograms and m² is their height in metres squared.
BMI is a useful screening tool, but it doesn't directly measure body fat or account for factors like muscle mass, bone density, age, and sex.
⚠️ Important: BMI is a general indicator, not a diagnostic tool. Athletes may have a high BMI due to muscle mass. Always consult a healthcare professional for personalized health advice.
❓ Frequently Asked Questions
BMI doesn't distinguish between muscle and fat. Athletes, elderly people, and pregnant women may get misleading results. It's best used as a general screening tool alongside other health measurements.
A BMI between 18.5 and 24.9 is generally considered healthy for adults. However, optimal BMI can vary based on age, ethnicity, and individual factors. Consult your doctor for personalized guidance.
For most adults, checking BMI once every few months is sufficient. If you're actively working on weight management, monthly checks can help track progress. Focus on trends rather than daily fluctuations.
Children and teens require age and sex-specific BMI charts (BMI percentiles). Standard adult BMI calculations don't apply to growing children. Consult a pediatrician for child health assessments.
