First of all, it is the negative emotions. When you are at loggerheads with your loved one, troubled or angry with someone, at this point, reasoning such as: now I'm really sick, so I'm gonna go eat something delicious. When trouble fell heavily, the food can soften the blow and act according to the principle of sedation, it is a kind of replacement for alcohol.
But this tactic is a bad habit that bring only temporary comfort. Once people had a bite, he realizes that the issue where he's stressed and decided not to. In addition, his gnawing thought that will need to lose weight. All this double burden rests on the soul, and this is the hand again reaches for the refrigerator to cope with the new leaning stress. And a vicious circle.
Why the best medicine against stress is chocolate? If man eating a salad of vegetables (but, incidentally, no mayonnaise), then maybe it would be a good thing. But somehow pulls it on chocolate, pies, chips, potatoes, cakes and so on. It has its own reasons.
1) Sugar and fats contained in the starchy foods stimulate the production in the body dopamine. Dopamine is a neurotransmitter, a hormone that stimulates the pleasure center in the brain of people. It is quite natural that a person has the desire to feel the pleasure of a meal again.
2) Pleasant memories. Yes, all people have meals that are associated with the touching moments in their lives. For example, if your mom for the holidays was preparing a very tasty cake, in a stressful situation, it will be the first thing you will want to eat.
However, of all vicious circles need to get out, as long stay in them is unlikely to have a positive impact on the body.
