What is BMI?

BMI (Body Mass Index) is a measure of body fat based on your weight in relation to your height. It applies to adult men and women and is calculated using the formula: BMI = weight (kg) / height² (m). While a useful screening tool, BMI doesn't directly measure body fat or account for muscle mass, bone density, or body composition.
