BMI is calculated as weight (kg) ÷ height (m)², and is a general screening measure — it doesn't account for muscle mass, bone density, or body composition.
Under 18.5 is underweight, 18.5–24.9 is normal, 25–29.9 is overweight, and 30+ is considered obese, per WHO standard ranges.
BMI is a general guideline and may not accurately reflect health for athletes, older adults, or those with high muscle mass. It's best used alongside other health measures and professional advice.
