ℹ️ About BMI
Body Mass Index (BMI) is a measure of body fat based on height and weight. It's used as a screening tool to identify potential weight-related health problems.
Formula: BMI = weight (kg) / height² (m²)
⚠️ Note: BMI is a screening tool and doesn't diagnose body fatness or health. Athletes, elderly, and pregnant women may have different healthy ranges. Consult a healthcare professional for personalized advice.
