Understanding BMI
BMI is calculated by dividing weight in kilograms by height in meters squared. For adults, common screening ranges are underweight below 18.5, normal weight from 18.5 to below 25, overweight from 25 to below 30, and obesity at 30 or above.
BMI is a general screening measure, not a diagnosis. It does not account for every factor affecting health, and different considerations may apply to children, pregnancy and some athletes. Discuss personal health questions with a qualified professional.
