About Body Mass Index (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 metres squared. It is used to broadly categorize a person as underweight, normal weight, overweight, or obese.
Frequently Asked Questions
What is a healthy BMI?
A healthy BMI for adults typically ranges from 18.5 to 24.9. A BMI below 18.5 indicates underweight, 25 to 29.9 indicates overweight, and 30 or higher indicates obesity.
Is BMI accurate for everyone?
BMI is a useful screening tool, but it does not measure body fat directly. It may not be accurate for athletes with high muscle mass, pregnant women, or the elderly.
