Define Classification of Weight Imbalance?
Obesity is defined as a condition with accumulation of excess body fat. Do you think that a measure of how much fat a person has in its body would serve as a tool for classification of obesity? No, because the measurement of direct body fat is difficult, so we use an indirect method, a ratio called the Body Mass Index (BMI) also termed Quctelet's index. This ratio estiminates dependence on frame size and provides the most useful method of measuring obesity in populations. BMI can be calculated from the following equation:
BMI = Weight (Kg) / Height (m)2
Where
kg = kilogram, m = metre
By this method, various grades of obesity, normal and underweight can be known.
