It is often believed that with all kinds of negative emotions, especially long ones, a person can easily lose weight. Moreover, this is more associated with a loss of appetite and, accordingly, with a decrease in the amount of food consumed.

Indeed, often this is exactly what happens, and most often happens at a young age. But how then to explain that the “more mature” population in response to the same long-term negative emotions, on the contrary, increases the appetite, and the body weight starts to go uphill? The riddle? Not at all!

Let me remind you that with age the number of neurotransmitters in the hypothalamus decreases. But also negative emotions, i.e. stress also causes a decrease in this level. In addition, the regulation of stress-related behavior is controlled by centers related to appetite regulation. So it turns out that stress and age in total cause a serious decrease in neurotransmitters in the hypothalamus, which in most cases leads to feelings of hunger, gluttony ... well, and then everything is clear.

So the increase in appetite associated with some unrest and anxiety is an indicator of a certain ill-being in the body, it is an indicator of the intensity of age-related disorders in it. But for children it is the other way round: they can be so carried away by games that they simply won’t feel hunger - because positive emotions create an anti-stress state, which leads to an increase in the number of neurotransmitters in the hypothalamus and a decrease in appetite.

Well, it seems that we sorted out the dependence of appetite on mood. I wonder if, on the contrary, the mood may depend on appetite, i.e. from food intake? Yes, and there are easily examples of this darkness!

Remember the joke: "The path to the man’s heart lies through his stomach." It turns out that she was not born from scratch and is based on underlying physiological processes.

Look: a man eats a piece of tasteful meat. The amino acids that make up the protein enter the bloodstream. Among the amino acids received is the amino acid tryptophan, from which a neurotransmitter called serotonin is synthesized in our brain. So this same serotonin controls mood. This means that an increase in its concentration is physiologically the basis for improving mood!

By the way, carbohydrates have the ability to improve mood. Entering the blood, carbohydrates increase the content of insulin in the blood. And insulin is the first assistant of tryptophan and in every possible way promotes its penetration into the brain. Well, then according to the pattern, serotonin is formed from tryptophan, and here it is - a feeling of deep satisfaction and good mood. Listen, maybe that’s why you always want sweet after meat, and after sweet meat? Or is it just me alone? ,)

So, dear, the conventional wisdom about the good nature of gourmets is quite a reasonable thing. And all would be fine if excess carbohydrates and insulin did not lead to weight gain, and if, with age, a violation of appetite regulation did not lead to a belated feeling of fullness.

Thus, an increase in body weight with age is a symptom of a loss of appetite that occurs due to an increase in the threshold of sensitivity of the hypothalamic centers to food and insulin.

Well, BON APPETIT? ,)

The effect of negative emotions on appetite

The motivation for food is strong at the time of feeling negative emotions. Under the influence of anger, women eat more intrusively than in situations of fear or sadness. In addition, they eat to reduce unpleasant emotions. Under the influence of emotions with high intensity (for example, fear, sadness), people tend to eat less food. However, a moderate or slight exacerbation of affect (for example, boredom) leads to the preference for more food. An increase in appetite as a result of negative emotions occurs both in people with eating disorders, obesity, and in healthy people. In a situation of experiencing negative emotions, the consumption of foods high in sugar reduces the experienced emotions. Foods that are associated with deliciously reduce negative mood and reduce stress, especially in people, are influenced by emotions. One of the products related to the ability to regulate an affective state is chocolate. In individuals with the correct body weight (BMI = 18.5 - 24.99 kg / m2), its consumption reduces the level of negative mood, and this decrease continues about three minutes after administration.

The effect of positive emotions on appetite

Although the literature is predominantly dominated by the thesis that appetite responds to negative emotions, more and more reports are now appearing that a positive mood can also help increase the amount of food consumed, as evidenced by recent studies by Bongers and Jansen. In a situation of experiencing a positive mood, women eat more than people with a neutral mood. In addition, they eat snacks more often in response to positive than negative emotions.

No doubt, what foods a person eats affects the activity of two independent nervous systems: the brain (excitation of the reward center) and the intestinal nervous system (named by Gerson as the “second brain”). The emotions experienced (emotional states) can be both a cause and a consequence of food.
