1. There are two hormones which are directly opposite and at the same time perfectly supplement each other - it is грелин and leptin. The first is connected with arousing appetite and increase in the eaten food. When you in a stomach have nothing, грелин begins to come to blood. Then signals come to a hypothalamus which directly affects behavior of the person in food questions. As a result the person has an appetite and also the feeling of hunger appears. Leptin is a hormone of fatty tissue with opposite function. It is developed after the stomach was filled. Leptin regulates power exchange and reduces appetite. Thus, it turns out that the reason of overeating is connected with the fact that we simply pass a satiety signal.
2. Dopamine is one more hormone which is connected with absorption of food. It is considered to be that dopamine is the chemical factor which is responsible for encouragement of a brain. In addition there is an opinion that function of dopamine is as follows – not to be responsible for pleasure but only only to anticipate it. We catch a smell of tasty food, we see it, and the splash in dopamine results. In the modern world food can be met anywhere – in shops, on billboards and so on. Therefore it is no wonder that the splash in dopamine can happen a set of times a day, and it is in turn the direct road to overeating. It is usually possible to eat more than including because of various food supplements and sugar which block a satiety signal. The more you will eat the products containing fructose the less will seem to you that you gorged on.
3. What size your portion is of great importance. The fact is that the brain far receives not at once a signal that you gorged on. Estimating the volume of a portion visually, the person can eat until devastates a plate. The volume of portions also is connected with caloric content. For example, vegetables which are associated with healthy food quite often order in a double size, believing that low-calorie dishes can be eaten in unlimited number. However it far not so, and absorption of healthy food in double and threefold sizes, of course, leads to overeating.
4. The more you watch TV at meal time, the more you eat. It occurs because we are distracted by the events on the screen, so, we release also to a look a signal of satiety again and again we overeat. There is one more factor, similar to the TV, because of which we eat more - it is communication. Try is and at the same time also to talk to someone. You make sure that in the company it will be eaten much more, than alone.
