Before beginning to unravel the meaning of the term body mass that we are now dealing with, it is necessary to proceed to establish its etymological origin. Specifically, we can determine that it is made up of two words that come from Latin:
• Mass, emanates from the Latin word “massa”. This in turn derives from the Greek “madza”, which was used to refer to a cake that was made with flour as the main ingredient.
• Corporal, meanwhile, comes from the Latin “corporalis” which is made up of two clearly differentiated parts: “corpus”, which is synonymous with “body”, and the suffix “-al”, which indicates that something is “ relative to”.

The physical magnitude that allows to indicate the amount of matter containing a Body is known as mass. The unit of mass in the International system is he kilogram (kg.).

Bodily, on the other hand, is what belongs to or Body. Among the various uses of this concept, the body can be the set of organic systems that constitute a living being. The bodyFor example, it is made up of the head, the trunk, the arms (the upper extremities), and the legs (the lower extremities).

The body mass, therefore, it is linked to the amount of matter present in a human body. The concept is associated with Body Mass Index (BMI), which consists of associating the weight and the height of the person to find out if that relationship is healthy.

Specifically, the following results are stipulated based on the figure obtained from the aforementioned calculation:
• If the number obtained is below 18.50, it is established that the person in question is underweight.
• In the event that the result determines a figure between 18.50 and 24.99, it can be said that the individual is in a normal situation in terms of weight.
• If the amount obtained is between 25 and 30, it is established that the person is overweight.
• Finally, if the resulting figure is greater than 30, it is established that the man or woman to whom it belongs has an obesity problem. This is mild if it is between 30 and 34.99; it is average if it is between 35 and 39.99 and finally suffers from morbid obesity if it exceeds the amount of 40.

The weight, by itself, is not a relevant data to know the state of Health of a person. Two people can weigh eighty kilograms each, yet one may be in excellent athleticism and the other may be obese. A weight of eighty kilos is normal for those who measure 1.90 meters, but it constitutes a risk for someone who measures 1.60 meters.

The BMI, created by the Belgian statistician, sociologist and naturalist LAJ Quételet, is calculated dividing weight (in kilograms) by height squared (in centimeters). It is necessary to consult a table to know if the BMI reveals a healthy weight or some disorder (underweight or overweight) that needs to be corrected.
