The BMI is actually the Body Mass Index that is used by doctors or we can say many people who are not doctors use this scale to see if they are fit and healthy all over the world by now. This is a measure or ‘scale’ by name, that is used to calculate the obesity based on the ratio of one’s weight and height as well. It is one of the calculations that does not need any heavy equipment or machinery to be done and can be done at home very conveniently as well. For a person to calculate what his BMI is he needs to know all about his weight and height.
A BMI scale is necessary so that people get a general idea of the situation that their bodies are in, so that in the future they can avoid any diseases and risks that may be there had they not calculated their BMI and started taking care of their body and health at the same time then as well. However, we must all be aware of the fact that a BMI calculator is not something a person can completely rely on as there are advantages, of course, but there are some disadvantages too.
BMI is the simplest way to measure the obesity among a huge number of people in a group and then the doctors can carry out the experiments so as to investigate the obesity epidemic for example the diet pattern of all the people who are obese or over weight you can say. This is important so that the common behaviors of the overweight people can be acknowledged and looked after so that the people who are obese do not get all those harmful diseases that are bound to occur if their weight increased with the same rate all along.
The disadvantage of the BMI calculator is that yes it measures the weight according to the height of the person, but it does not take into account the cause of the weight, is it is the lean tissue that weighs that much or the fat. And in this case we can say that one would never know if they are overweight although they lie in the normal weight category. This means that people with a lot of fat and still in the normal weight category might be under the danger of the diseases which they would never think would occur to them as they fall under the normal weight category of the people. This is how the BMI scale can be deceiving and it should not be relied upon completely as it does not take into account the technicalities while it calculates the body mass of the person.
