What is body-mass index and why is it important?
The result shows your BMI.
Your body mass index (BMI) decides what your ideal weight should be, keeping your height in mind. If you real weight is more than your BMI, then that means you are overweight.
The BMI is defined as the body mass divided by the square of the body height, and is denoted in units of kg/m, resulting from mass in kilograms and height in metres.
The BMI is an attempt to quantify the amount of tissue mass (muscle, fat, and bone) in an individual, and then categorize that person as underweight, normal weight, overweight, or obese based on that value.
In broad terms, a BMI under 18.5 places you in the underweight category and between 18.5 to 24.9 you are deemed normal – this is what we should all be aiming for. This moves on to being overweight with a BMI of between 25 to 29.9, obese at over 30 and morbidly obese if you have a BMI of over 40.
