Body Mass Index (BMI) is the ratio of your weight scaled to your height. It is used to measure the weight category you fall in. It measures your weight in kilograms divided by the square of your height in meters. It provides an indicative value that can help you decide whether you need further investigation.
BMI is a part of the Body Composition Analysis (BCA). BCA aims at quantifying the amount of tissue mass (muscle, fat, bone) in your body to be able to categorize you as an underweight, normal weight, overweight or obese individual. It is a statistical tool widely used by most health, fitness, and medical professionals to calculate your total body fat.
