Due to the growth of living standards, typical for most people inactive lifestyle, poor nutrition with increasing amounts of refined products, permanent stress the international community in the 21st century, faced with the global health care and social issue of fattiness and overweight. According to studies of the World Health Organization, this question problem relate to almost all countries, age groups and social conditions of the population. It is not only a cosmetic defect, this is a serious violation of metabolic processes that raises the risks of many illnesses, including heart diseases, diabetes and hypertension.
In order to calculate the optimal weight and adiposity diagnosis, doctors often use the body mass index (BMI), the magnitude of the mass of a person and its growth. Body weight may be insufficient, normal or abnormal. Ideal body weight is determined by several methods:
- Brock’s formula: height in centimeters minus 100
- Bernhardt`s formula: height in centimeters multiplied by the circumference thorax and divided by 240
- BMI (the body mass index) calculated by dividing of body mass in kilos by height in centimeters squared (kg m2)
By virtue of BMI is possible to find out whether your weight corresponds to the norm:
18.6-24.9 normal body weight
26.0-29.9 excessive body weight
30.0-34.9 obesity of the first degree (+20-50% of norm)
35.0-45.0 the second degree adiposity (+50-100% of normal)
45.0 or more — a critical level than (+100% of normal)
But worth remembering that the body mass index doesn’t deducts the right amount of fatty adjournment, in some people, such as sportsmen, the mass index exceeds the norm but they do not have an excessive accumulation of tallow and as a result — corpulence.
Overweight usually results from a combination of factors, including:

- Lack of sleep. Sleep that lasts less than 7 hours a day can lead to hormonal unbalancing and, as aftereffect, uncontrolled expansion of appetite. Also, your organism may start to call for high calorific food and foods rich in carbs; this as well increases the hazard of morbid corpulence.
- Obesity can be caused by primary disease, including Prader-Willi syndrome, Cushing's syndrome, polycystic of the ovaries and other diseases. Some disorders, such as arthritis, promote the crossing of the boundaries of permissible mass indirectly, due to the restricting of an active mobility.
- Some medical drugs can cause problems if not counteract their action through dietary, fitness or other sports
