Question 1

What is BMI?

Accepted Answer

BMI (Body Mass Index) is a measure of body fat based on height and weight. It's used as a screening tool to categorize weight status: underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), or obese (≥30).

Question 2

How accurate is BMI?

BMI is a useful screening tool but doesn't directly measure body fat. It may overestimate body fat in athletes and underestimate it in older adults. Use it alongside other measurements like waist circumference for a more complete picture.
