Important Facts about Body Composition.
It is important to know the body composition of an individual in order to be able to estimate the health condition. So not only one's weight, but its quality needs defining, which means dividing the human body in two major components:
- Lean body mass: bones, muscles, viscera, water, organs, blood
- Fat body mass: adipose cells
Under equal weight conditions of weight, these two masses have different volumes.
Body fat mass - what is normal?
The total body fat mass is calculated by summing up the essential fat (or primary fat) and the spare fat (or storage fat). The essential fat is necessary for the metabolism and some spare fat, which is theoretically surplus, is necessary for those who carry out physical activities. Therefore, the normal percentage of fat mass on the body weight is approximately 16 % for men and 27 % for women.
Overall well being.
For a correct control of one's ideal weight, it is important, besides weight, to compare the body fat percentage and the body water percentage while losing weight.
The body water % is an important indication of the overall «well being» of a human being as water is the single most important component of body weight and represents more than half (about 60 %) of the total weight.
With the increase of fat deposits, obese people have a lower body water % than lean people. Body water % is an overall composite number, so below 40 % would normally be seen as too low, and above 70 % as too high.
Quality of life - Body Composition
The exact knowledge of the body composition (calculation of lean body mass, fat body mass and total body water contents), allows a correct estimate of the excess fat and at the same time determines the advisable weight as a function of the user's nutritional condition.
Furthermore, knowledge of the body composition allows us to combine a correct nutrition and physical activity in order to improve the quality of life, promote health and prevent pathologies. This electronic personal scale allows you to evaluate body composition and automatically calculates the body fat and water percentages in relation of height, age and sex.
