At the moment, adherence to the principles of a healthy lifestyle (HLS) is very popular. It is considered an integral part proper nutrition. To maintain your weight or bring yourself into desired shape, you need to eat balanced and well. Therefore, it is important to understand what the energy value of foods is, how many calories are contained in 1 gram of proteins, fats and carbohydrates.

Calorie content of proteins, fats and carbohydrates
The energy value(EC) of food is determined by the amount of energy that the body receives when eating them. The most important nutrients that almost completely provide a person required calories, are proteins (B), fats (G) and carbohydrates (Y).
EC is measured in calories (cal), or more precisely, in kilocalories (kcal). 1 kcal equals 1000 calories.
Caloric content of the main food components:
- in 1 g B - 4 kcal;
- in 1 g of U - 4 kcal;
- in 1 g F - 9 kcal.
From the list presented, it is clear that fats have the highest energy value, while proteins and carbohydrates are 2 times less caloric.
Why you need to know EC
Despite the fact that the most high-calorie substances are F, the basis of nutrition is U. A balanced diet contains about 45-50% U, 30% B, 20% F.
It should be understood that nutrition, including large quantity Well, it will be high-calorie. A person on a diet consumes no more than 1500 kcal daily. If his diet is balanced, he can afford a large number of variety of dishes. And if 50% of his menu is F, which have a high energy value, they take up the entire supply of calories for the day. With this ratio, the number of dishes will be halved. Therefore, if you want to lose weight, the level of F decreases to 10-15% and B increases.
Knowledge of energy value nutrients it is also necessary in the opposite situation - if necessary, increase the weight. Actors often have to gain about 15-20 kg in 1-2 months. The basis of the diet in this case is fat. And if you need to gain muscle mass (for example, for athletes), nutrition should be based on proteins. But at the same time, a balanced diet only works in conjunction with strength training.
And some secrets...
The story of one of our readers Irina Volodina:
I was especially depressed by the eyes, surrounded by large wrinkles, plus dark circles and swelling. How to remove wrinkles and bags under the eyes completely? How to deal with swelling and redness?But nothing ages or rejuvenates a person like his eyes.
But how do you rejuvenate them? Plastic surgery? Learned - not less than 5 thousand dollars. Hardware procedures - photorejuvenation, gas-liquid peeling, radiolifting, laser facelift? A little more affordable - the course costs 1.5-2 thousand dollars. And when to find the time for all this? Yes, it's still expensive. Especially now. So for myself I chose a different way ...

The energy value- one of the most important characteristics of food products, which determines their nutritional value. It is determined by the amount of energy received by the body from the food components included in the food consumed, depends on the content of carbohydrates, fats, proteins and organic acids in it.
For food products, the energy value is usually given per 100 grams of product, or per serving for packaged products, includes information about three main components (fats, proteins, carbohydrates) and total energy value in kcal and kJ. (1 kcal = 4.1868 kJ)
The table shows only the average values for each class of substances. Exact values may vary slightly from substance to substance.
The daily calorie intake of a person depends on age, weight, height, gender, lifestyle, it is determined by the body's energy costs for different kinds activity and basic exchange. Moreover, the basal metabolism in women is slightly less than in men. According to regulations European countries an adult male of average build needs about 2500 kcal per day, while a woman needs only 2000 kcal per day.
Many different calculators have been published that allow you to calculate the daily calorie intake depending on the task (weight loss, weight gain, keeping fit), gender, age, height, weight and activity level based on lifestyle.
Everyone knows that the calorie content of foods is calculated from the energy released during the digestion of food. Wherein minerals and vitamins are non-caloric. Main nutritional ingredients that affect the energy value of meals are proteins, fats and carbohydrates. Let's talk about this in more detail, and in particular about what is the calorie content of proteins, why the body needs them, and how they should be consumed.
Usually, when calculating calories, most of all look at the fats and carbohydrates that are found in food. But the calorie content of protein foods, as a rule, is ignored. Of course, these questions are the most relevant for those people who want to quickly get rid of extra pounds.
At the same time, proteins are very important for the normal functioning of the body. They are involved in the structure of tissues, essential enzymes and hormones. But, of course, this does not mean that they should be consumed in excessive quantities. Such a diet will also lead to an excess of calories, and with it, to excess fat mass.
The most high-calorie, of course, are fats. One gram of substances they have is equal to nine kilocalories. At the same time, there are more than half as many calories in proteins and carbohydrates: there are only four kilocalories per gram. It turns out that when a protein gram is broken down, about four kilocalories are released. Therefore, people who want to adjust their weight indicators should definitely find out the optimal level of diet and study the calorie content of proteins, as well as fats and carbohydrates.
According to average estimates, it is believed that a person should consume from two to three thousand kilocalories per day. In fact, this indicator should be individual. It depends on various factors such as body weight, activity level, age and professional activity. If you want to lose weight, you should not pay attention to the calorie content of proteins. The reduction should be made by limiting the intake of carbohydrates and fats.
Every day human body up to one hundred grams of protein is required. If we consider herbal products, then most of them are found in soybeans: per hundred grams - it contains approximately thirty grams of protein. Peas and beans are also rich in them. It can be found in large quantities in some animal products, among which eggs stand out, sea fish, bird, fish caviar. They also have up to thirty grams of protein per hundred grams.
Often speaking of proteins, they mean directly a part of a chicken egg. This product is eaten raw, boiled, and fried. Some people, on a diet, separate it from the yolk and use it separately. The omelette then turns out to be very useful and tasty. Let's study how many calories are contained in this product.
For 99%, this species is able to be absorbed by the body. Therefore, he alone can fully cover the daily norm for a person. Egg on average weighs about seventy grams. At the same time, the protein in it is fifty grams. Therefore, speaking of one hundred grams, we mean the parts separated from two eggs. Their calorie content is only 45 kilocalories. It turns out that eating an egg without a yolk, you can not worry about your figure. But it does not contain carbohydrates and fats at all. Therefore, this product is extremely rich in proteins and is very easy to digest. Thus, these biological active substances, taken from two or three eggs, completely cover daily requirement organism.
In addition, the protein includes glucose and enzymes that allow you to quickly digest food, preventing the intestines from becoming clogged with toxins. It also contains vitamins B, A, D. Even if there are no meat products in the diet, the substance will fully provide the necessary niacin, the absence of which interferes with the formation of sex hormones and the proper functioning of the brain. Thus, the complete rejection of animal food can even lead to the loss of reproductive function.
The low calorie content of protein has made the product extremely popular in cooking: it is included in all types of pastries and sweet cream. Salads with its addition become more useful. At the same time, you can find a lot of yolks useful application. For example, they are used to make crumbly biscuits. In addition, there are many beauty recipes using this part of the egg. Many face and hair masks are made from it, either alone or with other ingredients.
The calorie content of 1 g of protein, of course, also depends on the method of its preparation. To all beneficial features preserved, it is necessary to take into account the method heat treatment. So, one hundred grams of boiled protein contains from forty to forty-four kilocalories. At the same time in fried there will be more of it, since other fats also take part in this process. Yes, the whole fried egg per hundred grams will be as much as 360 kilocalories.
So, daily rate for a person, the average is 2500 kilocalories. But, as mentioned earlier, these indicators are very individual. So, for women under 25 years old, leading a sedentary lifestyle, this rate is 2000 kilocalories. From 26 to 50 years old - and even less, about 1800. However, if they lead an active lifestyle, then the norm increases by 200 kilocalories daily.
For men who lead a sedentary lifestyle, under the age of 30, the norm per day is 2400 kilocalories. And for those who are older, from 31 to 50 years old - 2200. But if their lifestyle is active, then up to thirty years old they need 3000 kilocalories, and up to 50 years old - from 2800 to 3000.
For clarity, the following table of caloric content of products and ready meals is given.
The daily protein intake is 100 grams, which corresponds to 410 kilocalories. But fats should be consumed less per day, only 60 grams. But, in terms of kilocalories, it will be equal to 560. Fats are necessary for the body. For example, Omega 3s are fatty acids. A good balanced diet is daily allowance, consisting of 30 grams of animals and 30 grams vegetable fats. Carbohydrates per day is enough 370 grams. In terms of kilocalories, this turns out to be 1530. Thus, the body needs them the most. And it's natural. After all, it is carbohydrates that provide the body with the necessary energy.
Conclusion
If necessary, the body will be able to adapt to a smaller amount of protein consumed daily. However, it is unreasonable to subject it to such loads. The amount of protein consumed, which is needed every day, should not be reduced. Weight loss should come from carbohydrates and fats. Then there is simply no place for fat deposits to come from.
Proteins are involved in almost all processes. Their deficiency makes negative impact on the body. This leads to changes in the liver, deterioration in the absorption of substances, hormonal background, disruption of the endocrine glands. Even deaths have been recorded long time respected low calorie diets. Eating protein foods is very important for maintaining human health. For Russians, this issue is especially relevant, since, judging by the studies, we usually do not have enough of this biologically active substance in our diet.
To guarantee good health yourself and family members, it is important to organize proper nutrition and speech in this case It is about maintaining a balance between proteins, fats and carbohydrates. In parallel with this, the burning question arises regarding how many calories are in carbohydrates, proteins and fats. With development modern technologies appeared a whole bouquet diseases associated with a sedentary lifestyle, and the residents of modern megacities are especially worried about being overweight, to which many declare a real war. One way to combat unwanted pounds is to reduce the number of calories consumed.
One of the achievements of our time is the Internet, thanks to which many things can be done today, including calculating calories consumed. To do this, it is enough to have a calculator and a table of calorie content in hand. different products. It is known that the basis excess weight There is fatty food, and, according to research data, there are about twice as many calories in fats as in proteins and carbohydrates. It is difficult to say unequivocally how many calories in carbohydrates, fats and proteins, since it depends on many factors, where the main one is the calorie content of a particular product.
For a normal existence, a person needs to receive a certain number of calories per day, and this depends on factors such as age, gender and vital activity. So, for women leading a normal lifestyle, it is enough to consume 2000 calories per day, for men this figure increases to 2400 kcal, and if you lead an active lifestyle or work physically, the number of calories should be increased to 3 thousand. If you decide to lose weight, then it is enough to consume up to 1500 calories per day. At the same time, it is worth remembering that there are calories that are not absorbed by the body, and in this case we are talking about fiber. When calculating, the “weight” of 1 gram of proteins and carbohydrates is conditionally taken as 4 calories, and the calorie content of fats is 9 kcal per 1 gram, while the calorie content alcoholic beverages calculated on the basis that 1 gram of alcohol "weighs" 7 calories.
When starting to draw up a diet and taking into account the number of calories for each day, you should know that for the normal functioning of your body (if we take the average person leading a normal lifestyle) about 100 grams of protein food per day, about 50-60 grams fatty foods and at least 300-350 grams of foods rich in carbohydrates. Information about how many kcal in carbohydrates, in this case, given the large amount of their consumption, is the most important. For the indicated amount of food containing carbohydrates, there are about 1500 kilocalories. This is a big part daily dose allowable calories to consume, so knowing how many calories in a carbohydrate is important in order to properly formulate a diet.
As for the rest of the products, there are an average of 400 calories per 100 grams of protein, and fatty foods weigh about 800 kcal per 100 grams of product, and given that we need to eat almost half as much fat per day, then the amount consumed with fat food calories are halved. It should also be remembered that fats are contained, as in vegetable food, and in food of animal origin, but vegetable fats do not lead, as a rule, to the appearance of extra pounds, so there should be more of them in your diet than animal fats.
Calorie content- this is the main indicator on which it depends whether your weight will change. Do you want to lose weight or, conversely, gain weight - it all depends on the calorie content of the diet. The principle is simple - if you consume more calories than you need, you gain weight. If less, you lose. This is called a surplus or calorie deficit.
calories are energy. We get energy from food, which is why diet is the easiest and most effective method regulate your own weight. Unfortunately or fortunately, we have not yet mastered photosynthesis or nuclear fusion, so managing your own diet is exactly what will help you manage your body weight.
In addition to the calorie content, or the energy value of food, we must also take into account qualitative composition food. Otherwise, it is called the energy and plastic function of food. The main parameters for accounting here are proteins, fats and carbohydrates, as well as the proportions of their ratio.
If by controlling caloric content, we can regulate body weight, then by controlling the ratio of BJU (proteins, fats, carbohydrates), we can partly contribute to the recomposition of the body - try to lose weight by reducing fat, not muscle tissue.
The lion's share of the success of recomposition depends on resistance training, which forces your body to use its muscles and therefore preserve them, but the quality of the nutrition is no less important here.
Squirrels is the main building material that our body can use. The cells of our body are constantly being renewed, so we need a constant supply of new building material, which we can only get from food.
Caloric content of proteins - 4 Kk per 1 gram.
Carbohydrates is the main energy source. It is using carbohydrates that our body receives most of the energy for daily activities.
The calorie content of carbohydrates is 4 Kk per 1 gram.
Fats are an energy reserve "for a rainy day", and in addition they also have plastic functions. Sufficient fat content in food is important for the functioning of joints and ligaments, for the absorption of fat-soluble vitamins, and so on.
Calorie content of fats - 9 Kk per 1 gram.
As you can see, there are no "necessary" and "unnecessary" elements. That is why, for example, any diet that severely restricts the intake of one of the macronutrients (usually either fats or carbohydrates) cannot give long-term results and often lead to malfunctions in the body.
When planning a diet, you need to consider all 4 parameters.
We are calorie based. As a rule, in order to find out how much Kk per day you need, just multiply your body weight by 30. You can find more accurate methods in this article.
For normal life, a person needs 1 gram of protein per kilogram of body weight. If you are actively involved in sports, or hard physical labor, then this parameter can be increased to 1.5. Digesting more than 2 grams of protein per kilogram of body weight without appropriate pharmacological support is difficult.
The amount of fat is usually equal to 1 gram of fat per kilogram of weight. During the period of weight loss, it can be reduced to 0.5 grams, but not for a permanent period.
The rest of the calories are filled with carbohydrates.
Example.
Body weight is 60 kilograms, in total we get 1800 Kk per day. 60 grams of protein \u003d 240 Kk, 60 grams of fat \u003d 540 Kk, 1020 Kk remains, which are equal to 255 grams of carbohydrates. Everything is simple.
In order to manage the process of losing weight or gaining weight, we manage calories. At the same time, we “play” exclusively with the amount of carbohydrates, without touching proteins and fats.
You should not drastically change the caloric content of the diet - as a rule, it is enough to add or remove 150-200 Kk in order to start the necessary process.
Using this information, you can easily build your diet. About the choice of food - in the next article.
The energy value of foods is quantified using a unit of measurement called a calorie. It has been established that the protein and carbohydrate components of food contain 4.1 kilocalories (kcal) per 1 gram, fat is more energy-intensive and contains 9 kilocalories per 1 gram.
Thus, the total calorie content of the product is calculated by the formula:
Calories = 4.1 x Protein + 4.1 x Carbs + 9 x Fat
Meat products
Meat products practically do not contain a carbohydrate component, they are rich in proteins and fats.
Animal fat at overconsumption can provoke an increase in cholesterol levels and the development of atherosclerosis. However, one should not give up meat products– meat and eggs contain a complete set essential amino acids required by the body to form muscle mass.
For healthy eating Choose lean meats and egg whites. Calorie table of meat products:

Beverages
Water, coffee and tea without milk and without sugar have zero calories.
All other drinks are quite energy-intensive and when counting daily calories they must be taken into account. Pay attention to the calorie content of alcoholic beverages. The alcohol contained in them is estimated at an energy intensity of 7 kilocalories per 1 gram. This is less than that of fats, but almost twice as much as that of proteins and carbohydrates.
Nuts and seeds
Nuts and seeds are rich in vegetable proteins, fats and fiber.
This is very high-calorie product, but you should not completely abandon it, since nuts contain many nutrients.
Seeds can be sprinkled on salad, and a handful of nuts can be taken with you and used as healthy snack. How many calories are available in nuts and seeds:
Cereals and legumes
Cereals supply, necessary for the body for a balanced diet.
Consuming slow-acting carbohydrates prevents a spike in blood glucose and keeps you full for hours. In addition to carbohydrates, legumes contain a large amount of vegetable protein. Calorie content of cereals and legumes per hundred grams:
Flour products and sweets
These products have practically no nutritional value, but they are very energy intensive.
When losing weight, the amount of flour products and sweets is recommended to be reduced to a minimum or completely abandoned. These products do not contain nutrients, have a significant value of the glycemic index, supply the body with fast carbohydrates and “empty” calories, which are more likely to be stored as fat. Calorie sweets:
Sauces
Sauces and various dressings are usually added to salads or used with meat. Since many of them are quite high in calories, this fact should be taken into account when calculating daily calories. Sauce calorie table:
The Best Products for Weight Loss
The main goal of weight loss is to saturate the body with nutrients without adding unnecessary calories.
Pay attention to products with a low fat content, the method of preparation of the dish also matters. It is preferable to steam, boil or bake in the oven.
The best products for weight loss in the table:
| Product Category | Recommendations |
| Meat products | Choose boiled chicken breasts or cook lean beef or lean pork in the oven. Egg white should be separated from the yolk to reduce the calorie content of the product. Avoid all processed meats. |
| Dairy | Make a choice in favor low fat milk, cottage cheese, yogurt and kefir to saturate the body with protein without additional calories. |
| Fish and seafood | Steamed or grilled fish and seafood can be added to the diet without restrictions. |
| Vegetables | Reduce your consumption of potatoes and corn. Prefer use fresh vegetables for salads or steam them. |
| Fruit | Eat fruits only fresh. Fresh fruits low-calorie with the exception of avocado and banana, but contain a lot of fructose, which is a fast carbohydrate. If you want to lose weight, consider this fact. |
| Beverages | Water, coffee and tea without milk and without sugar in unlimited quantities. Other drinks should be avoided during the period of weight loss. |
| Nuts and seeds | No more than 10 nuts per day, taking into account their calorie content in daily diet. |
| Cereals and legumes | Boil porridge in water. Should not be avoided complex carbohydrates when losing weight - without them, you will quickly break loose and break the diet. |
| Flour products and sweets | Refuse for a period of weight loss and limit after this period. |
| Sauces | For salad dressing, it is enough to sprinkle it with vegetable oil, vinegar or lemon juice. |
Best Mass Gaining Foods
To build muscle mass, you should increase the daily intake. This, however, does not mean that you need to eat all high-calorie foods in a row.
For a healthy diet, focus on complete proteins and complex carbohydrates.
| Product Category | Recommendations |
| Meat products | Along with boiled breasts, make scrambled eggs and lean steaks and chops. |
| Dairy | Any dairy products are allowed, but it is better to focus on whey protein and cottage cheese as a source of casein. |
| Fish and seafood | Boiled, fried and steamed fish and seafood. |
| Vegetables | Limit your consumption of fresh vegetables, as the fiber will prevent digestion of the food you eat. |
| Fruit | Limit sugary fruits due to fast carbs or use them after your workout. |
| Beverages | Give up alcohol - it suppresses protein synthesis in the body and reduces the ability of muscles to recover after a workout. |
| Nuts and seeds | Limit serving size as nuts are difficult for the body to digest and high consumption cause discomfort in the digestive tract. |
| Cereals and legumes | Oatmeal, buckwheat and lentils have a moderate glycemic index and provide the body with many useful trace elements. |
| Flour products and sweets | Limit these foods due to fast carbohydrates. Can be used as a cheat meal or immediately after a workout. |
| Sauces | Give preference vegetable oil There are a lot of preservatives and salt in artificially prepared sauces. |

The energy value, or caloric value is the amount of energy released in the human body from food during digestion. The energy value of the product is measured in kilo-calories (kcal) or kilo-joules (kJ) per 100 grams. product. Kilocalorie, used to measure the energy value of food, is also called " food calorie”, therefore, when indicating calories in (kilo) calories, the prefix kilo is often omitted.
Also, per 100 grams of the product, it is indicated
The nutritional value- the content of carbohydrates, fats and proteins.
For products not yet ready to eat - pasta, cereals, dumplings and the like - energy and the nutritional value is indicated per 100 grams of the original (that is, raw or dry) product.
Energy value of the main components of food
The table shows only the average values for each class of substances. Exact values may vary slightly from substance to substance.

The energy value of products is calculated per 100 g of the edible part. To determine the theoretical caloric value, multiply the calorific value of a nutrient by the percentage of the respective nutrient. The sum of the products obtained is the theoretical calorie content of 100 g of the product. Knowing the calorie content of 100 g of a product, you can determine the calorie content of any of its quantities (300 g, 1 kg, etc.). Knowing the theoretical caloric content, you can find the practical (actual) calorie content by multiplying the result of the theoretical caloric value by the digestibility in percent and dividing the product by 100. Example Determine the theoretical calorie content of 1 cup (200 g) of cow's milk. According to the table of chemical composition or according to the textbook of commodity science, we find the average chemical composition cow's milk(in%): fat - 3.2; proteins - 3.5; milk sugar- 4.7; ash - 0.7. Solution. 1. Caloric content of fats in 100 g of milk: 9 3.2 \u003d 28.8 kcal. 2. Caloric content of proteins in 100 g of milk: 4 3.5 \u003d 14.0 kcal. 3. Caloric content of carbohydrates in 100 g of milk: 3.75 4.7 \u003d 17.6 kcal. 4. The theoretical calorie content of 100 g of milk will be: 28.8 kcal + 14.0 kcal + 17.6 kcal = 60.4 kcal kcal = 505.4 kJ 6. The actual calorie content of 100 g of milk is: (28.8 94) : 100 + (14.0 84.5) : 100 + (17.6 95.6) : 100 = 54.73 kcal = 229 kJ
All foods differ in their content of fats, proteins, carbohydrates and nutrients. Also, each product has a certain calorie content - that is, it can give us a certain amount of calories.
Vitamins or minerals do not contain calories, they are found in proteins, fats and carbohydrates. The calorie content of food depends on them, since it is during their processing that energy is released. most high calorie have fats, in second place - carbohydrates and proteins. If you want to increase body weight, you need to increase the calorie content of your diet by 20-25% (better - due to fats and proteins), and if you want to lose a few kilograms - then reduce it by 20% (it is better to reduce the consumption of carbohydrate and fat for this). food). A change in the calorie content of the daily diet by more than 20% is fraught with stress for the body and a failure in metabolism. This knowledge will help you easily control daily consumption calories, and therefore your weight, as well as a balanced diet that will give you required amount energy and keep you going throughout the day.
How many calories are in carbohydrates, fats and proteins, are high-calorie foods needed in the diet?
Fats are the highest in calories. 1 g of fat during splitting provides about 9 kcal of energy. calorie content of food great content fat, respectively, the highest is fatty meats, fish and poultry, lard, vegetable and butter, as well as foods such as nuts, which are high in vegetable fats. The share of fats in the total daily diet is about 30%.
Twice as low as that of fats, the calorie content of carbohydrates is a little more than 4 kcal per 1 g.
You can independently calculate the calorie content of some dishes. For example, a teaspoon of sugar (2 g) is almost 100% carbohydrate. Accordingly, we determine that tea with sugar will give us about 9 kcal. It takes about 5 minutes of running on the spot or 10 minutes of driving a car to burn them. Carbohydrates are divided into complex and simple. Simple are sugar and saccharides found in fruits, sweet vegetables, honey, berries. They are quickly broken down and absorbed into the blood. Complex ones are starch, fiber, etc., found in bread, flour, cereals and cereals, vegetables and fruits, pasta, legumes. They split for a long time, gradually. The calorie content of simple and complex carbohydrates is the same, but due to the fact that the rate of their breakdown is different, they give off energy in different ways. Saccharides “flare up”, give up all their energy, which is immediately spent by the body or stored in adipose tissue if there is too much energy. Complex carbs, like a stove, give off energy gradually, so they will provide you with strength for longer than the same amount of simple ones. The calorie content of carbohydrates is the basis of the calorie content of our diet. They should be at least 60%, since it is the calories obtained from complex carbohydrates that provide us with constant energy and performance throughout the day.
The calorie content of proteins is about 4 kcal per 1 g. Proteins are found in lean meat, poultry and fish, dairy products, eggs, seafood, legumes, mushrooms. In the daily diet, they are given a share of 10-15%.
Knowing the calorie content of foods, we can exclude from the diet high-calorie foods with a small amount of nutrients and replace them with nourishing and nutritious meals with lower calories. Or, if we need a quick energy boost (for example, when playing sports), we can eat something with high content simple carbohydrates and provide yourself with high activity for 1-2 hours. You can also afford high-calorie foods for breakfast - you will get a boost of energy, and by the end of the day all the calories eaten in the morning will be processed.
Before going to bed, on the contrary, we will choose dishes with a lower calorie content in order to sleep peacefully and have a good rest. Do not forget that you need to have dinner at least 3-4 hours before bedtime - then dinner will have time to digest and part of the calories received at dinner will already be spent.
What are many calories
High calorie foods include:
- sugar and products containing sugar (jam, syrups);
- potato;

In ordinary life, we do not need too many calories - we spend no more than 2000-2500 kcal per day with an average physical activity, so all extra calories the body stores it in fat stores. Therefore, it is better to replace fatty meat in our diet with lean, chicken thighs - chicken breast, white polished rice - brown rice, salo - lean ham, mayonnaise - fat-free sour cream, fried potatoes- stewed beans, etc..
But there are cases in life when you need to eat exactly what has a lot of calories, and “fast” ones - this, as was said, is relevant for athletes (after training, they even drink carbohydrate shakes to make up for energy losses). Also, this method is used by schoolchildren and students when passing exams - they eat chocolate during the exam. On hikes, physical activity, in adverse temperature conditions (for example, in the cold in winter) or, if necessary, to maintain efficiency and activity for additional time (for example, for motorists), high-calorie foods will come in handy - you eat a small amount of food and get quick result in the form of energy. As a source fast calories suitable, as already mentioned, chocolate, honey, caramel, sweets, sweet fruits, nuts and even soda (although it is very harmful).
In everyday life, it is better not to get carried away with high-calorie foods and eat a balanced meal with an average calorie content and a high content of all nutrients and useful substances that the body needs to function normally. If you decide to eat something high-calorie, carbohydrate, it is better to do it in the morning so that by the end of the day all your extra calories have time to be processed.
