WATER CONTENT IN THE BODY
Water is the most important single component of body weight. Water represents more than
half of the total weight and almost two thirds of the weight of the body (muscle) tissue. Water
plays many important roles in the human body. All cells in the body - the skin, glands, mus-
cles, brain or any other, may function properly only when the body is supplied with sufficient
amount of water. Water also plays an important role in regulating body temperature, particu-
larly through sweating.

The knowledge of the level of fat and water in the body can provide some kind of guidance
when adjusting the diet, exercise programme and fluid intake and thus can contribute to the
improvement of heath condition. The results of water measurement depend on the propor-
tion of fat and muscles in the body. If the proportion of fat is high or the proportion of muscles
is low, the results of water measurement may be low. Please note that the measurements of
body weight, fat and water content provide useful information to maintain a healthy lifestyle.
THE AMOUNT OF MUSCLE TISSUE IN THE BODY
This function indicates the amount of muscle tissue in the body. The muscle mass includes
skeletal muscles, smooth muscles (such as heart muscle and gastrointestinal tract muscles)
and the water contained in these muscles.

Along with the increase in muscle mass, increases the demand for energy which helps to re-
duce the body fat and weight.
THE AMOUNT OF BONE TISSUE IN THE BODY
The weight of our bones depends on the body composition, physical activity, health condi-
tion. We should remember that physical activity strengthens the bones. This, however, is not
a big change and in fact we do not feel this on a daily basis or when measuring the body com-
position. In this kind of measurements it is an additional information about the total weight
of our body.
