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 meters squared.
BMI Categories
BMI is categorized as: Underweight (<18.5), Normal weight (18.5-24.9), Overweight (25-29.9), and Obese (≥30). These categories help assess health risks.
Limitations
BMI doesn't account for muscle mass, bone density, age, sex, and ethnicity. It's a screening tool, not a diagnostic measure. Consult healthcare professionals for personalized advice.
