What does metabolism in the body mean. How to normalize metabolic processes in the body? How to restore the correct metabolism

What is metabolism, how to improve its speed and efficiency - these questions are asked by every person who is concerned about weight loss. We invite you to find out what metabolism is in the human body and what is its role in shaping health at the cellular level. You can improve the metabolism in the body with the help of simple methods available to you, we will discuss most of them below.

The meaning and role of metabolism: characteristics and functions

Metabolism is the main property that distinguishes living from non-living. It is characterized by processes of synthesis and decay, which continuously occur in the body and between which a constant balance is maintained. This is precisely what the main role metabolism, during which the transformation of all consumed substances occurs.

With the stoppage of metabolism, life also stops, which leads to the decomposition of proteins that are carriers essential functions human body: structural, motor, protective, enzymatic, etc. Therefore, it is quite difficult to overestimate the importance of metabolism, the better it is, the healthier the body is.

The functions of metabolism, or metabolism (this word came to us from the Greek language, where it means "transformation, change") - the process of continuous transformations chemical substances in the body, ensuring its growth, development, cell renewal and vital activity in general.

The characteristic of metabolism includes not only a description this process, but also the dependence of other body functions. The speed of metabolic processes depends on:

• the activity of the expenditure of energy from food. So, with a reduced metabolic rate in the body, processes aimed at the formation of energy reserves in the form of fatty deposits;
• blood circulation intensity;
• state of immunity;
• hormonal background. Conversely, the state hormonal background with some endocrine disorders: diseases thyroid gland, dysfunction of the pituitary gland, etc. - helps to slow down metabolic processes.

How to improve the metabolism of the body

Before you establish the metabolism of the body, it is important to undergo an examination under the guidance of an endocrinologist. Diseases must be ruled out endocrine system.

What can you do to increase your metabolic rate?

• diet;
• food composition;
• sleep and wakefulness;
• muscle tone.

Let's look at each of these factors.

Proper nutrition and metabolism

food serves the only source energy and building material for the formation of complex structures of the body. To human body constantly updated, you need to regularly consume the necessary nutrients. Metabolism and nutrition are closely related, one depends directly on the other. Organization proper nutrition for metabolism - this is a guarantee of ridding the body of unnecessary toxins and toxins, lack of energy and many other problems.

A stable rate of metabolic processes in the body is maintained through frequent fractional nutrition and small portions.

The main role in this belongs to breakfast: a carbohydrate side dish (porridge, potatoes, pasta or pancakes, pancakes), filling a quarter of the plate, serves as a source of energy and strength for the whole day.

The highest rate of metabolic processes is observed from 5-6 am to 12 noon. You can support it by having a full breakfast.

Eat five meals a day in portions of 300-500 kcal every four hours and never skip breakfast.

The highest rate of metabolic processes in the body is observed in the period from 5-6 am to 12 noon. If you systematically wake up and refuse to full breakfast, do not be surprised that it is difficult for you to keep fit. After lunch, the metabolic rate gradually slows down, so the last main meal - dinner - should be light and consist of a lean, non-fried protein meal made with chicken, fish, cottage cheese, or egg white, and a vegetable side dish. Light vegetable soup instead of a side dish is only welcome. Dinner should be no later than four hours before bedtime. And an hour before bedtime, you can afford yogurt or kefir.

If you start the day with a full breakfast, fat burning is accelerated by about 10%. Skipping your morning meal will have the exact opposite effect and your metabolism will continue to doze off until you eat.

Thus, it is also important to have lunch, afternoon tea and dinner on time. As trite as it may sound, fractional nutrition beneficial effect on metabolism. The processing of food takes 10% of the calories that we spend per day. Frequent appointments food force the body to be constantly in working condition - its activity is not interrupted and does not slow down. Therefore, you need to eat five times a day in small portions, approximately 300-500 kcal each. The break between meals should not exceed four hours. In this case excess fat will not accumulate in the body.

Just do not reduce portions to the size of a tea saucer and do not arrange fasting days for yourself. For some reason, in our society, the myth persists that fasting helps to normalize metabolism. This is not true.

Any drastic changes and dietary restrictions only prevent the body from working. When too little food enters the stomach, the body begins to conserve energy. If you starve for several days, your metabolism can slow down so much that you won’t spend even 1000 kcal per day. As a result, starving people lose weight only at first, and then this process stops. And restarting it can be very, very difficult.

Features of metabolism

The peculiarities of metabolism are that the rate of processes directly depends on the amount of biologically active substances and microelements supplied with food. Vitamins and trace elements are part of various enzymes and are catalysts, that is, accelerators, of many bio chemical processes in the body. Therefore, vegetables and fruits in any form should be present in the diet every day. Be sure to include fish and seafood in the menu: seaweed and other algae, etc. Just do not get carried away with shrimp, as they have a lot of cholesterol. The high content of iodine in seafood has a positive effect on the metabolic rate. Iodine is also found in carrots, arugula, whole grains, etc. But, for some thyroid diseases, iodine intake should be agreed with your doctor.

Vitamins and accelerate many biochemical processes in the body. Therefore, you should eat fruits, vegetables and seafood daily and take a multivitamin a couple of times a year.

metabolism and sleep

Full sleep - ideally seven hours - with awakening before eight in the morning allows you to maintain a stable metabolic rate and maintain a slender figure. Many active processes, such as the breakdown of fat, occur in the body during sleep. And we lose weight in a dream. At modern man metabolism and sleep are interconnected, since during the working day and wakefulness too much energy is spent on processing incoming information.

The less we sleep, the less fat stores are broken down. Late heavy meals also interfere with this process.

If you have a tight dinner before going to bed, then at night fat reserves will begin to be intensively deposited. The hormone insulin is responsible for their formation, the level of which rises after eating, and sweet foods contribute to its greater release. If for some reason you have to eat late at night, give preference to unsweetened foods: vegetables, kefir, cottage cheese. Simply put, do not eat sweets at night. Only after the activity of insulin decreases, the work is included growth hormone, or growth hormone, - it is he who is involved in the breakdown of fat reserves. But it works only at night in the phase deep sleep, this is necessary for the body to extract energy for the coming day.

Metabolism in the human body

This is a set of chemical reactions that ensures the vital activity and growth of the cell. Metabolism is what is the basis of a living organism, it is the exchange between chemical composition human and environment.

All chemical and natural elements - proteins, fats and carbohydrates - participate in the metabolic processes of our body. Each fulfilling its role - proteins, creating building material, and fats with carbohydrates, regulating the balance of energy costs - clearly and smoothly interact with each other. They come to the aid of minerals and vitamins that improve the cellular environment.

The exchange of substances consists of two sides:

1. dissimilation - decomposition, decay nutrients.

2. assimilation - synthesis, creation and assimilation of new substances by the body.

These processes go on in parallel throughout life. There are the following stages:

1. The supply of nutrients to the body

2. Suction them out digestive tract

3. Redistribution and absorption of nutrients (tissue stage)

4. Isolation of residues of decay products that cannot be absorbed in the body

Metabolic processes in the body are fast and intensive, although the body does not high pressure and temperature. This speed is provided by the participation of enzymes and other substances.

The role of metabolism

Metabolism deserves to be given the closest attention. After all, the supply of our cells depends on its well-established work. beneficial substances. The basis of metabolism is chemical reactions occurring in the human body. We get the substances necessary for the life of the body with food.

In addition, we need more oxygen, which we breathe in with the air. Ideally, there should be a balance between the processes of construction and decay. However, this balance can often be disturbed and there are many reasons for this.

Causes of metabolic disorders

Among the first causes of metabolic disorders, a hereditary factor can be distinguished. Although he is incorrigible, he can and should be fought! Also, metabolic disorders can be caused by organic diseases. However, these disorders are often the result of our malnutrition.

Both an excess of nutrients and their deficiency are very harmful to our body. And the consequences can be irreversible. An excess of some nutrients occurs as a result of excessive consumption of fatty foods, and a deficiency - when strict observance different diets for weight loss. The main diet is most often a monotonous diet, which leads to a lack of essential nutrients, which in turn will inevitably lead to the development of various diseases. Allergies to most foods are possible.

Metabolic diseases

Even after balancing all metabolic processes, supplying the body with the missing vitamins, we run the risk of getting a number of serious diseases caused by the decay products of our cells. Decay products have everything living and growing, and this is perhaps the most dangerous enemy for our health. In other words, the body must be cleansed of toxins in time, or they will simply begin to poison it. Remaining in excess, decay products cause chronic diseases and slow down the work of the whole organism.

In case of violations carbohydrate metabolism arises serious disease- diabetes mellitus, if not fat metabolism cholesterol accumulates (), sickening heart and blood vessels. Free radicals, which become abundant, contribute to the occurrence of malignant tumors.

Frequent consequence metabolic problems is also obesity. This group also includes gout, digestive disorders, some forms of diabetes etc. imbalance minerals and vitamins leads to damage to muscles, bones, serious violations of cardio-vascular system. In children, this can lead to serious consequences in the form of growth and development retardation. It is worth noting that the additional use of vitamins is not always recommended, because their overabundance can also have negative consequences.

Prevention

In order to regulate the metabolic processes in our body, we must know that there are some substances that prevent the formation of toxins and improve the quality of metabolism.

First, it is oxygen. Optimal quantity oxygen in the tissues significantly activates metabolic processes.

Secondly, vitamins and minerals. With age, all processes slow down, there is a partial blockage of blood vessels, so it is important to control the receipt enough minerals, carbohydrates and oxygen. This will provide Good work water-salt metabolism cells, because as time passes, the cell, drying up, no longer receives all necessary elements for your life activity. Knowing this, it is important for us to artificially nourish aging cells.

There are many recommendations and drugs that regulate metabolism. AT folk medicine seaweed gained popularity White Sea- fucus, it contains a valuable set of minerals and beneficial vitamins needed to improve metabolism. Proper nutrition, exclusion from the diet of foods containing cholesterol and others harmful substances- another way to the perfect functioning of the body.

Metabolism(or metabolism, from the Greek μεταβολή - “transformation, change”) (hereinafter referred to as “O.v.”) - this is the natural order of the transformation of substances and energy in living systems underlying life, aimed at their preservation and self-reproduction; the totality of all chemical reactions that take place in the body.

The free MH 3 formed during the deamination of amino acids for the body; it binds to acids or is converted to urea, uric acid, asparagine, or glutamine. In animals, ammonium salts, urea and uric acid are excreted from the body, while in plants, asparagine, glutamine and urea are used in the body as reserve sources of nitrogen. Thus, one of the most important biochemical differences between plants and animals is almost complete absence at the first nitrogenous waste. The formation of urea during the oxidative dissimilation of amino acids is carried out mainly with the help of the so-called ornithine cycle, which is closely related to other transformations of proteins and amino acids in the body. Dissimilation of amino acids can also occur by their decarboxylation, in which CO 2 and some amine or a new amino acid are formed from the amino acid (for example, histamine is formed during the decarboxylation of histidine - physiologically active substance, and upon decarboxylation of aspartic acid - a new amino acid - (α- or β-alanine). Amines can undergo methylation to form various betaines and important compounds such as choline. Plants use amines (along with some amino acids) for the biosynthesis of alkaloids.

III. The connection of the metabolism of carbohydrates, lipids, proteins and other compounds

All biochemical processes occurring in the body are closely related to each other. The relationship between protein metabolism and redox processes is carried out in various ways. The individual biochemical reactions underlying the process occur due to the catalytic action of the corresponding enzymes, i.e. proteins. At the same time, the products of protein breakdown - amino acids - can undergo various redox transformations - decarboxylation, deamination, etc.

Thus, the deamination products of aspartic and glutamic acids - oxaloacetic and α-ketoglutaric acids - are at the same time the most important links in the oxidative transformations of carbohydrates occurring in the process. Pyruvic acid, the most important intermediate product formed during fermentation and, is also closely related to protein metabolism: interacting with NH 3 and the corresponding enzyme, it gives the important amino acid α-alanine. The closest connection between the processes of fermentation and respiration with lipid metabolism in the body is manifested in the fact that phosphoglyceraldehyde, formed at the first stages of carbohydrate dissimilation, is the starting material for the synthesis of glycerol. On the other hand, as a result of oxidation pyruvic acid leftovers acetic acid from which high molecular weight fatty acid and various isoprenoids (terpenes, carotenoids, steroids). Thus, the processes of fermentation and respiration lead to the formation of compounds necessary for the synthesis of fats and other substances.

IV. The role of vitamins and minerals in metabolism

In the transformations of substances in the body, water and various mineral compounds occupy an important place. participate in numerous enzymatic reactions as part of coenzymes. So, a derivative of vitamin B 1 - thiamine pyrophosphate - serves as a coenzyme during oxidative decarboxylation (α-keto acids, including pyruvic acid; vitamin B 6 phosphate ester - pyridoxal phosphate - is necessary for catalytic transamination, decarboxylation and other amino acid metabolism reactions. Vitamin A derivative is included in the composition of the visual pigment.The functions of a number of vitamins (for example, ascorbic acid) have not been fully elucidated. Different types organisms differ both in their ability to biosynthesize vitamins and in their needs for a set of certain vitamins that come with food, which are necessary for normal exchange substances.

An important role in mineral metabolism is played by Na, K, Ca, P, as well as others. inorganic matter. Na and K are involved in bioelectrical and osmotic phenomena in cells and tissues, in the mechanisms of biological membrane permeability; Ca and P are the main components and; Fe is part of the respiratory pigments - hemoglobin and myoglobin, as well as a number of enzymes. Other trace elements (Cu, Mn, Mo, Zn) are also necessary for the activity of the latter.

A decisive role in the energy mechanisms of metabolism is played by esters of phosphoric acid and, above all, adenosine phosphoric acids, which perceive and accumulate energy released in the body in the processes of glycolysis, oxidation, and photosynthesis. These and some other energy-rich compounds (see high-energy compounds) transfer the energy contained in their chemical bonds for use in the process of mechanical, osmotic and other types of work, or for the implementation synthetic reactions coming with energy consumption (see also bioenergy).

V. Regulation of metabolism

The surprising coherence and coherence of metabolic processes in a living organism is achieved through strict and plastic coordination of metabolic processes. both in cells and in tissues and organs. This coordination determines given organism the nature of the metabolism that has developed in the process historical development, supported and directed by the mechanisms of heredity and the interaction of the organism with the external environment.

The regulation of metabolism at the cellular level is carried out by regulating the synthesis and activity of enzymes. The synthesis of each enzyme is determined by the corresponding gene. Various intermediate products of O. v., acting on a certain site, which contains information about the synthesis of a given enzyme, can induce (start, enhance) or, conversely, repress (stop) its synthesis. So, Escherichia coli with an excess of isoleucine in a nutrient medium stops the synthesis of this amino acid. Excess isoleucine acts in two ways:

• a) inhibits (inhibits) the activity of the enzyme threonine dehydratase, which catalyzes the first stage of the chain of reactions leading to the synthesis of isoleucine, and
• b) represses the synthesis of all enzymes necessary for the biosynthesis of isoleucine (including threonine dehydratase).

Inhibition of threonine dehydratase is carried out according to the principle of allosteric regulation of enzyme activity.

The accumulation in the blood and tissues of a number of intermediate metabolic products (lactic, pyruvic, acetoacetic acids) is observed in violation of oxidative processes, disorders and beriberi; violation mineral metabolism can lead to shifts acid-base balance. Cholesterol metabolism disorder underlies some types. Serious metabolic disorders include a violation of protein absorption in thyrotoxicosis, chronic suppuration, some; violation of the absorption of water with lime and phosphorus salts with osteomalacia and other diseases bone tissue, sodium salts - with Addison's disease.

Diagnosis of metabolic disorders is based on the study of gas exchange, the relationship between the amount of a substance entering the body and its release, the definition of chemical constituent parts blood, urine and other secretions. To study metabolic disorders, isotope tracers are administered (for example, radioactive iodine- mainly 131 I - with thyrotoxicosis).

Treatment of metabolic disorders mainly aimed at eliminating the causes that cause them. See also "molecular diseases", hereditary diseases and literature attached to these articles. (S. M. Leites)

In an attempt to lose weight or gain muscle mass, we begin to delve into various aspects dietology: how to eat right, how much macro- and micronutrients you need to achieve sports goals, which foods are better and which are worse. But there will be no complete clarity in these matters without an understanding of what metabolism is. In today's article, we will analyze how the metabolism of various nutrients occurs and what factors affect the metabolic rate.

Definition

From a physiological point of view, metabolism is all the chemical reactions that occur in your body that are necessary for normal life. AT Everyday life metabolism is commonly referred to as metabolism.

What is it plain language? Metabolism is all the processes that occur for the assimilation and use of certain nutrients. We regularly receive certain micro and macro elements with food, water, air, etc. Due to metabolism, we dispose of them: we use them as energy, we accumulate them in the form of adipose tissue, we use them to restore injured tissues, and much more.

How are metabolism and body weight related?

There is such a thing as basal metabolism. This is a kind of indicator of how much energy your body needs at rest to maintain normal functioning. The calculation is based on your gender, age, height, weight and activity level. Before you try to gain or lose weight, be sure to calculate your basal metabolic rate. No need to meddle in this jungle without understanding what, how and why you are doing.

For example, at rest, your body needs 2,000 calories to properly perform all functions and keep all systems working. If you want to lose weight, you need to consume fewer calories. If you want to gain muscle mass - more. Of course, all this is just a mathematical calculation, and this figure is not always true. If you are a young man of an ectomorphic body type and you have fast metabolism, you will not gain excess weight, even significantly exceeding your norm. If you have a slow metabolism and a genetic tendency to be overweight, the opposite is true.

The essence of metabolism

In order for all these nutrients that we consume to be fully absorbed by the body, they must be decomposed into more simple substances. For example, our muscles do not need protein per se to repair and grow. We only need individual amino acids (there are 22 in total) that are needed for muscle activity. In the process of digestion, the protein breaks down into individual amino acids, and the body absorbs them for its own needs. For example, leucine and valine immediately go to restore muscles damaged during training, tryptophan goes to the production of dopamine, glutamine goes to maintain immune system etc. The breakdown of a complex substance into simple ones is called anabolism. During anabolism, the body receives energy in the form of calories that we spend during physical activity. This is the first stage of our metabolism.

The next stage of metabolism is catabolism. This phenomenon is usually associated with the decay muscle tissue or fat burning, but its meaning is much wider. In a broad sense, catabolism is the synthesis complex substances from simple ones. Tissue regeneration is directly related to catabolism, we see this in the healing of wounds, blood renewal and other processes that constantly take place in the body without our knowledge.

Protein metabolism

Protein is needed by our body for a number of important biological functions, among which:

1. Regeneration and creation of new muscle cells.
2. Recovery of microtraumas in muscle tissue after strength training.
3. Acceleration of all biochemical processes.
4. Synthesis of sex hormones and normal functioning of the endocrine system.
5. Transportation of nutrients: vitamins, minerals, carbohydrates, hormones, etc.

In the process of assimilation, the protein breaks down into individual amino acids. This process is called protein metabolism.

Not only the quantity, but also the quality of protein is important. The amino acid composition is what determines the biological value of a protein. If it is scarce, then it covers only a small part of the body's needs. This mainly applies to proteins from plant products. An exception, some nutritionists consider legumes because they contain a fairly large amount of essential amino acids.

Things are different with animal proteins. Usually its amino acid composition is much more extensive, and it contains a large amount of essential amino acids, which are so necessary for athletes during periods of intensive training.

Carbohydrate metabolism

Carbohydrates are the "fuel" for our body. Glucose, to which carbohydrates break down during metabolism, tends to accumulate in the liver and muscles in the form of glycogen. It is glycogen that makes the muscles visually voluminous and filled. It has been proven that muscles filled with glycogen are stronger and more resilient than “empty” muscles. Therefore, full-fledged strength training in gym impossible without a sufficient amount of carbohydrates in the diet.

Without carbohydrates, you will be incapacitated, lethargic and sleepy. That is why athletes often complain about bad feeling and retardation. There are carbohydrates with high glycemic index(simple) and low glycemic index (complex).

Simple carbohydrates include all sweets, confectionery, pastries, White rice, most fruits, juices and other sugary drinks. Their glycemic index ranges from 70 to 110. Complex carbohydrates include all cereals, durum wheat pasta, vegetables, whole wheat bread and some dried fruits.

The metabolism of simple and complex carbohydrates is fundamentally different. Simple carbohydrates are also called fast carbohydrates, as they quickly saturate the body with energy, but this energy is not enough for a short time. Yes, you feel an increase in efficiency, a surge of energy, an improvement in mood and concentration, but this lasts for about 40 minutes at the most. Their absorption rate is too fast, they quickly break down to glucose. This provokes a strong surge of insulin, which contributes to the accumulation of adipose tissue, and also harms the pancreas. In addition, the intake of simple carbohydrates in large quantities completely kills the appetite, and this is fundamentally important during the period of gaining muscle mass, when you need to eat 6-8 times a day.

Yes, the end product of the breakdown of any carbohydrate is glucose. But the fact is that for complex carbohydrates, this process takes much longer - from 1.5 to 4 hours. This does not lead to the accumulation of fat, since there are no sharp jumps in the level of insulin in the blood. Complex carbohydrates should form the basis of your diet. If you have enough of them, you will be able to work productively in the gym and beyond. If not, your efficiency will decrease.

The liver plays an important role in fat metabolism. It serves as a kind of filter through which the decay products of fats pass. Therefore, for those who do not follow the principles of proper nutrition, liver problems are common. The amount of fat in your diet should be strictly limited. Most nutritionists recommend eating up to one gram of fat per kilogram of body weight. Moreover, the emphasis should be on unsaturated fatty acids, which are rich in fish and seafood, nuts, vegetable oils, avocado and eggs. They have a positive effect on the work of the cardiovascular system, as they help reduce blood cholesterol levels.

Often fat is deposited not only under the skin, but also between the internal organs, and outwardly it is absolutely imperceptible. It is called visceral fat. It is very difficult to get rid of it. Violations of fat metabolism leads to increased accumulation of visceral fat. Because of this, they receive less oxygen and useful nutrients, and their performance gradually deteriorates, which can lead to the development of serious diseases.

Exchange of water and mineral salts

The most important thing in diet and proper nutrition is far from calories, proteins, fats and carbohydrates. Our body simply cannot exist and function normally without water. Our cells, internal organs, muscles, blood, lymph are almost entirely composed of water. Many athletes forget how important it is to drink enough fluids and how the water-salt balance affects your well-being and performance.

If you do not consume enough water, you will constantly experience headaches, increased blood pressure, drowsiness, irritability and problems with the gastrointestinal tract. Your minimum daily rate– 3 liters pure water. This normalizes the water-salt balance, improves the performance of the kidneys and will help speed up the metabolism.

Most of water and mineral salts leaves the body with urine and sweat. Therefore, in addition to plain water It is recommended to use mineral water on a regular basis. It will cover the body's needs for mineral salts and other beneficial micronutrients. If the salt reserves are not replenished, the condition of the joints, ligaments and bone tissue will deteriorate. The concentration of mineral salts in different waters can be different. Only qualified specialist based on analyses.

How does the metabolic rate change with age?

This is a purely individual moment, but with age, in most people, the rate of metabolic processes decreases. It usually occurs before the age of 30. Every year, metabolism slows down more and more. Therefore, the older the person, the higher the tendency to gain excess weight. From the age of 25, one should Special attention give proper nutrition. Your rate of calories, proteins, fats and carbohydrates should be clearly calculated. Deviations from this in one direction or another can be minimal, otherwise the metabolism will slow down, and you will gain extra fat mass. You should try to eat as often as possible in small portions. The basis of your diet is animal proteins and complex carbohydrates with a low glycemic index. After 6-7 pm, it is recommended to completely abandon carbohydrates. Food should be fully digested, so the more fiber in your diet, the better.

How does gender affect metabolic rate?

Men are more likely to gain muscle mass than women. This is facilitated, first of all, by the male sex hormone testosterone, without which muscle growth is almost impossible. The level of endogenous testosterone in healthy man several tens of times higher than that of a woman.

Muscle mass requires more energy to function. Accordingly, the basal metabolism in men will be higher, because your muscles consume energy even in a state of complete rest. In other words, in order to collect excess weight, a man will need to eat more calories than a woman.

For women, the situation is somewhat different. High level estrogen promotes the formation of adipose tissue. Women who do not follow the diet and are far from the world of sports and fitness usually gain weight quickly. Fat, unlike muscles, does not require additional energy costs for its functioning. Accordingly, women do not have such a fast metabolism as men.

How does diet affect metabolism?

In order for your metabolism to be normal, and even accelerated in the future, you need to adhere to the following simple rules in nutrition:

There are a number of metabolic-boosting foods: citrus fruits, apples, nuts, leafy greens, celery, kale, broccoli, and green tea. Metabolism becomes faster due to great content vitamins, minerals and antioxidants in these foods. In addition, cabbage and broccoli are so-called negative calorie foods. The body needs more energy to absorb them than they contain. Accordingly, you create an energy deficit, and the speed of metabolic processes increases.

Metabolic disorders

Metabolic processes depend on many factors: genetics, functioning gastrointestinal tract, the work of the endocrine system, the state internal organs, diet and exercise regimen and many others.

However, the most widespread problem is malnutrition. Overeating, fasting, eating too much junk food, too much fatty foods and simple carbohydrates in your diet all lead to a slow metabolism. All diets that guarantee a quick result will lead to the same. Even if at first you received some positive result, after the diet, all the lost kilograms will return with a vengeance, and the metabolism will slow down again. In conditions of slow metabolism, toxins and free radicals because they do not have time to be excreted from the body.

Metabolic disorders in most cases have the following symptoms:

1. A sharp decrease or increase in body weight;
2. Constant feeling of hunger or thirst;
3. Increased irritability;
4. Deterioration of the skin.

Remember: boosting your metabolism and burning fat is a long and painstaking process. This will not happen in a week or two without harm to health, which can be expressed in an increase in body fat, swelling, deterioration of the skin, a decrease in anaerobic endurance and a deterioration in the condition of the hair.

Proper nutrition is the key to health and slim figure. To improve the metabolism in the body, you should know which foods are especially important for metabolism. So you can build a diet that will allow you to maintain health, and also will not allow you to gain extra pounds.

About metabolism

Metabolism or metabolism is a complex of chemical processes that occur in the body. These processes help break down food so that it is converted into energy. Such metabolic processes of human life play important role. They are involved, for example, in growth, cell renewal, reproduction, respiration. Enzymes help to properly proceed metabolism, normalizing it. They accelerate the digestion of food, the absorption of proteins, fats, carbohydrates (BJU). BJU, in turn, control energy costs and provide the basis for cellular regeneration.

Metabolism consists in the breakdown of nutrients and their formation, synthesis. In the body, such processes occur continuously and are divided into the following stages:

• Admission to digestive system nutritional elements;
• their absorption;
• Distribution for the purpose of participating in different life important processes organism, assimilation;
• And the removal of decay products.

There are 3 main types of metabolic disorders, the knowledge of which will help to normalize the process:

• Violation of protein metabolism. Characterized constant feeling hunger, excitability of the nervous system, irascibility, stress. In this case, experts often prescribe a protein diet;
• Violation of carbohydrate metabolism. Signs - a person loves coffee and drinks it constantly, does not like sweets, has poor appetite. The second option - a person loves sweets, constantly snacks on sweets, pastries and other simple carbohydrates. In this case, doctors prescribe a carbohydrate diet, which takes place under the strict supervision of a specialist;
• Mixed. This type of metabolism is characterized frequent fatigue person, anxiety, love of sweets and the presence of excess weight.

In any case, it is dangerous to self-prescribe treatment for yourself.

Why metabolism is disturbed

Proper metabolism helps the body maintain normal health. If it is broken, then the whole body suffers. Distinguish the following reasons that can disrupt metabolism:

• Bad habits;
• hereditary predisposition;
• Failure to comply with the norm of calories, due to which there is a loss or weight gain;
• Unbalanced diet;
• Lack of micro- and macronutrients in the diet;
• Impact harmful factors environment.
• Changing the balance of hormones; Hormonal disbalance;
• Violation of the function of the adrenal glands, pituitary gland;
• Diseases of the thyroid gland.

It is important to recognize metabolic disorders in a timely manner, avoiding deterioration in health. Some treatments involve taking medications, biostimulants. Such treatment takes place only under the supervision of a physician. Others - maintaining proper nutrition, physical activity, good vacation can be done on your own.

Vitamins and trace elements

It is possible to normalize metabolism thanks to vitamins and microelements. Vitamin complex prescribed after diagnosis by a dietitian. In addition to dieting, funds are also prescribed that restore metabolic functions body:

• vitamins(e.g. A, B, C, D). They are involved in all types of metabolism;
• Fish fat- reduces cholesterol in the blood, has a positive effect on blood vessels;
• Folic acid- participates in the process of hematopoiesis;
• Chromium- Stimulates the digestive system. Also, this substance in the body helps to normalize blood sugar levels, which reduces cravings for sweets;
• Iodine- activates the functioning of the thyroid gland;
