What is BMI?
Body Mass Index is a screening tool that uses height and weight to estimate if you're underweight, normal, overweight, or obese.
How is it Calculated?
BMI = weight (kg) ÷ height (m)². For imperial: BMI = (weight in pounds × 703) ÷ (height in inches)².
BMI Categories
Underweight: <18.5, Normal: 18.5-24.9, Overweight: 25-29.9, Obese: 30+
Limitations
BMI doesn't distinguish muscle from fat. Athletes may have high BMI but low body fat.
Health Considerations
BMI is one indicator among many. Blood pressure, cholesterol, and fitness level matter too.
Who Should Use It?
BMI is most accurate for sedentary adults aged 20-65. Consult a doctor for personalized advice.
