Understanding Body Mass Index (BMI)

BMI is a calculation based on an individual's weight and height. It is calculated by dividing an individual's weight in kilograms by the square of their height in meters (kg/m²). This simple numerical value is validated by research to estimate body fat levels. While BMI is essential for assessing potential weight-related health risks, one must consider a holistic viewpoint of a person before jumping to any conclusion.

Body Mass Index is the ratio to body weight (measured in kilograms) to height (measured in meters). It is a simple numerical measurement that enables the classification of people on the basis of their body composition.The WHO today recognizes the validity of the Body mass index (BMI) and has set the following ranges to determine the distinction between being thin and being overweight or obese.

Introduction

          In my post “What is Obesity – is it merely about BMI? What is obesity? I had defined obesity as an abnormal accumulation of fat such that health is impaired.
