Metabolism (metabolism)

To not take obesity evil by lot, which can't be avoided, in order to penetrate into the essence of the problem and not to make mistakes in the prevention and treatment of obesity, you need to know some basic information about the metabolism.
Energy balance
Body to carry out their vital functions (movement, thermogenesis, renewal of tissues) needs a certain amount of energy. This energy it gets from food. If energy is received more than the required balance in the body is disturbed, the excess energy is converted into fat and people fullness. If energy intake is less than its costs are spent energy stores of body fat and the person loses weight.

Calories or Joules

Let the body takes or uses up the energy in any form, sooner or later it transformed into waste heat. To some extent this is used to maintain a normal body temperature of 37 degrees. This temperature is the most favorable for all processes in the body. Therefore, your metabolism can be estimated on the basis of education and heat consumption. Still the basic unit was considered calorie. New international metric system introduces universal unit of energy is the Joule. Calories can be translated in joules, using the following ratio: 1 kilocalories (kcal) = 4,18 kJ (kilo). To the readers was easier to navigate, we cited in the text and tables of the energy value in both units.

Basal metabolism, or how much it costs us a dream

It is not true that because of the dream man acquires energy. And with the full physical and mental rest person spends a certain amount of energy, for example within an hour of sleep - about 250 to 300 kJ (60-70 kcal). Moreover, of the total energy consumption, the share of the liver, accounting for 27%, brain - 19%, kidneys-10%, muscle - 18% and heart-7%. Because in the dream, the power consumption is very small, excessively long sleep or passive recreation can contribute to weight gain. Therefore, overweight people should not allow yourself plenty of sleep and lie.
