Already ate, but still ready to use the dessert? This situation is familiar to many. And she often leads to a set of extra pounds.
Researchers from the Max Max Institute for the Study of Max Max are interested in why, even in a state of satiety, a person can easily absorb sweets and desserts. Why does such an additional electoral appetite arise for sweets and what is its mechanism?
Who controls the appetite
Scientists conducted an experiment on mice and revealed that in such a situation, special nerve cells (pro-Popiimalanocortin neurons) are activated and begin to secrete β-endorphin, stimulating appetite, which causes sugar consumption in a state of satiety. Moreover, these are the same cells that contribute to the appearance of a feeling of saturation when a person has eaten. It turns out that they are the culprits of attraction to sweets. But only to him. When this opioid path of activation of appetite in the brain of mice was blocked, they remained indifferent to sugar. Scientists believe that if such a method can be used in relation to a person, then you can help people not overeat or gain excess weight. However, the data obtained require further research and evidence.
“In our brain in the hypothalamus there are centers that are responsible for the feeling of hunger and a feeling of saturation. There are various hormones and substances that participate in this process, ”explained AIF.RU A dietitian, therapist, candidate of medical sciences, researcher at the Laboratory of Immunology of the FIC of Nutrition and Biotechnology Tatyana Solntsev. -In particular, the very famous glucagono-like peptide-1 (GPP-1), which regulates the appetite: the hormone is produced when the food enters the intestines and gives a saturation signal. The CHPP-1 is based on obesity medicines. There are other well-known hormones that regulate appetite: ghrelin, leptin, l-tyrosin, etc. In addition, neurons are found in regulatory hunger and saturation of brain structures that can even emit various substances that stimulate us to consume sweet products “.
And when a person ate sweet food, endorphins stand out – endogenous, that is, internal, opiates. They reduce pain, reduce the level of depression, discomfort, improve mood. That is why getting rid of a habit is sweet after eating is so difficult.
Why do you want a dessert?
To fight the consequences, we must first understand, why do we want sweets after eating? The doctor calls four main reasons.
The desire to eat sweet or fat can arise if the body lacks certain nutrients, including various minerals, such as iron, magnesium, zinc. “The body is not able to understand what kind of element it lacks, there are no receptors that would clearly signal: it is necessary to replenish the level of selenium. Therefore, there is a desire to just eat something unusual, ”says a dietitian.
Also, various emotional states can stimulate appetite. Some people are trying to fight stress, jamming it sweet. Others have a desire to eat delicious to celebrate some joyful event.
Insufficient sleep can also increase appetite. If a person has not slept, he feels the desire to eat with something sweet.
Finally, the desire to eat sweet after eating in some people can be just a habit. In childhood, such phrases said to many in childhood: do not eat sweet before eating, after dinner you will get candy, etc. “We are used to the fact that we have a sweet table or desserts always at the end of dinner or dinner. But, as it turned out, the desire to finish lunch with dessert can also have biochemical prerequisites, ”the doctor said.
How to get rid of a habit is sweet?
What can be done to overcome the desire to eat sweets after dinner? The doctor gives some tips.
Make sure that the diet has a sufficient amount of protein. The less it is, the more often we want to eat, including high -calorie foods – simple carbohydrates and fats. Protein food helps not only to enhance the feeling of satiety, but also to eat much less food in subsequent meals.
Oleic acid stops hunger. This is omega-9 polyunsaturated fatty acid, most of it in olive oil. Therefore, it is worthwhile to include olive oil in the diet, but still in moderate quantities.
Do not forget about spices. On the one hand, they stimulate appetite, on the other hand, as a rule, contribute to a reduction in the general calorie content of the diet, as they reduce the attraction to fatty and sweet foods.
Use more products with fiber. It can be whole grains and bread, green salads such as spinach with flaxseed, in principle, any vegetables and fruits, berries. Fiber is food for our good bacteria in the intestines, which are producing, including serotonin, and hormones of pleasure. In addition, plant fibers from cereals create a feeling of satiety, satisfaction from food without loading with excess calories.
Liquid food also contributes to a feeling of satiety and will prevent overeating. Soups, jelly without sugar, liquid porridge – all this is not very high -calorie, but it fills the stomach well and creates its fullness, which the mechanoreceptors in the walls react to, they send a signal to the brain that our body has been saturated.
If the dessert after lunch is just a habit or family tradition, it is better to get rid of it.
