About BMI:
Body Mass Index (BMI) is a person's weight in kilograms divided by the square of height in meters. It's a screening tool that can indicate whether a person has a healthy body weight for their height.
BMI doesn't measure body fat directly and doesn't account for factors like muscle mass, bone density, and ethnic differences.
