BMI introduction

BMI is a measure of overweight or obesity based on height and weight. And when muscle strength is measured, it is often used as a general indicator of whether a person’s weight is appropriate for their height. Specifically, the BMI value is used to classify a person as overweight, normal weight, overweight or obese, depending on where the value is found. This BMI range varies by region, age and other factors. It can be divided into different healthy categories, such as overweight and obesity. Being overweight or obese can have serious health consequences, so BMI is not an absolute measure of a healthy weight. But it is a good indicator that you need further testing or treatment. See the table below for the various BMI-based models used in our calculations.
