How to speed up metabolism? And do you need?

"Popular statement: The reason for excess weight is slow metabolism. And about people who do not fully fulfill, no matter how much they eat, it is customary to say that they have high metabolism. On the idea that with the help of special means, the metabolism can be accelerated, a variety of diet and advertising bid advertisements are built, but is it really? We understand.

A short answer: the metabolism or metabolism depends on the genetic features and the production of hormones and does not directly affect the presence or absence of excess weight, so if you are healthy, nor speed up, no one needs to slow down. Bades promising fast weight loss - in the best case of dummy, and at worst can harm health. Separate products, like grapefruits and green tea, can influence the absorption rate of calories (but not for metabolism!), But this effect is so insignificant that it is not worth it.

What is metabolism

Metabolism or metabolism is a biochemical process that occurs in the body of any living being, and is to turn food into energy. The rate of metabolism does not depend on our will and consciousness, it is individual and is determined by the peculiarities of the work of the thyroid and pancreas, adrenal glands, ovaries and pituitary glands, in which hormones are produced. Under the influence of hormones in the body, enzymes are allocated to splitting food and turn it into energy and the building material of our body - proteins, fats, carbohydrates, trace elements and vitamins.

The truth can be accelerated by the exchange of substances?

You really can affect the work of the glands. Just do it can only be done in the case of pathology. For example, hypoteriosis - a disease at which the function of the thyroid gland is reduced, as a result of which the body produces less hormones than. But only a doctor can put this diagnosis, and only he may find the necessary treatment.

Theoretically, dietary supplements that promise the acceleration of metabolism can indeed contain substances that affect the function of the glands - and this is truly dangerous. Around the world, the production and composition of additives is controlled poorly (they do not pass with strict certification as medicines), so it can be dangerous without consulting them with a doctor.

And what about diets?

Everything is not so unequivocal here. Certain products can really affect the rate of absorption of calories, but this is not related to the exchange of substances. Studies confirm that, for example, the use of a large amount of protein helps more effectively burn fat, but the reason here is not in the acceleration of metabolism, but in an increase in the thermal effect of food - the amount of calories that consumes the body for digestion, transportation and assimilation.

On average, the digestion accounts for up to 10% of the daily energy consumption of the body, and energy consumption is significantly different for different products. For example, for fats, it is about 3% of the calorie consumed, and for a protein - it reaches 30%.

The same applies to cold water (the body requires additional calories to heat it up to the body temperature) and some products, for example, acute pepper, grapefruit and green tea - their learning also requires increased energy consumption. In any case, this effect can only slightly increase calorie consumption, and success in weight loss will still depend on how many calories you consume and spend.

Sports nutrition 2: With attention to detail

"Physical activity is a celebration of human capabilities.

Competitive activity is a chance to show your opportunities.

The conquest of the title is the apogee athlete competitive activity.

Title is some kind of quintessence of success.

Success is what accompanies the most prepared.

That is why accuracy is important in any preparation. And the speech in today's article will not go about attitude towards planning the training process, but about accuracy in the kitchen.

Three macronutrients, without only no athlete, but also a private citizen, in principle, are proteins, fats and carbohydrates (hereinafter found). Proteins - building material for muscles, fats - general health and regulation of hormonal background, carbohydrates - ""fuel"" for training and competition. Any product on supermarket counters contains in certain proportions. The combination of these macronutrients in an absolutely any embodiment has its own energy value (calories). The total calirage during the day should cover the daily athlet needs depending on its routine of the day and the current period of loads.

The total outcome of the energy cost of the athlete body can be expressed by five metabolic variables:

TDC (Total Daily Caloric / Daily Calorie Consumption) = BMR (BASAL METABOLIC RATE / Main Exchange at rest) + RMR (Resting Metabolic Rate / Main Exchange in Sleep Stand) + EX (Exercise / Physical Activity) + TEF (Thermic Effect Of Feeding / Energy for digesting food) + Neat (Non - Exercise Activity Thermogenesis / Energy for small movements)

If the BMR indicator is still possible to calculate through the simplest formulas, the remaining variables are recognized using wearable gadgets and laboratory studies.

BMR = 25.9 x FFM (Fat Free Mass / Body Body Mission in Kilograms) + 284

Folding all the indicators together, you can clearly understand what exactly and in what quantity to put into the plate to your athletes. The power of elite athletes does not forgive the intuitive approach and negligence. I also want to note that BJO should be in certain proportions that depend on the specific period. For example, a basketball player during the preseason fees is best to eat as follows:

Proteins - 20% ration / fats - 20% ration / carbohydrates - 60% diet

Whereas during the competitive season the proportion of macronutrients should be close to the following values:

Proteins - 20% ration / fats - 25% ration / carbohydrates - 55% diet

By the way, for each team sport existed their recommendations for powering players.

Along with the main macronutrients, it is not necessary to underestimate the importance of hydration of competing athletes. In order for the athlete to be effective, it is necessary to 500ml drinking water to activity and 150 - 250ml every 15 - 20 minutes during its implementation.

There are no trifles in the sport of higher achievements, there are only parts. It is from the relationship to the details a final result folds. Everything is simple: what is the relationship, such and the level of professional.

Is it useful to sleep on the floor or not very?

"What prevents a good sleep? Most often inconvenient mattress and pillow. And here there are two news: good - you can fly to the floor, and bad is not a fact that it will help. We tell who useful to sleep on the floor and what will come of it.

Is it really useful on the floor?

""Sleep on the floor"" is literally a dream on the floor without a mattress and other support elements. Is it so someone sleeping? Yes, the Japanese and Koreans, for example, practice sleep on the floor. Another question is whether it is useful. There are few studies on this topic, therefore the science does not give an accurate answer. Tibetan and Kenyan nomads, for example, in general, instead of the pillow, use their hand - and they have no health problems, even, on the contrary. Physiotherapist Michael Tetley studied natural postures during sleep and noticed that these nomadic tribes rarely suffer from problems with the musculoskeletal system. But all the people are different - that one will benefit, another can harm. Primitive people also slept on Earth, but even they put a bunch of branches and leaves under themselves. Therefore, sleep on the floor is now and hundreds of thousands of years ago - not the same thing.

How to prepare a sleeping place? Should I sleep on the floor or better to put something?

Choose a convenient location - near the balcony and windows the bed is better not to post - it will be cold and noisy. Nearby should not be heating devices, furniture and other unnecessary parts.

Wash the floor - the place for sleep must be comfortable, clean and dry - in addition to the dust accumulated during the day, microorganisms may appear in a wet environment (especially on the wooden floor).

Prepare a sleeping place - the first time to sleep on the floor is optional, and it is unlikely that it will immediately work out. Tatami is suitable, futon, yoga mat, sleeping bag, a wicker mat, like the Japanese - the main thing, check the sheet (it will be pure and not so tough). You can start with a thin mattress, because if you sleep in a literal sense on the floor, the entire load will get to the muscles-stabilizers - the body will be constantly in voltage.

Change the pillow - the neck and the spine must be on the same line, so the bulk pillow will not fit. Exactly to keep the ""head-neck-spine"" position will help a flat pillow or a small roller. If you sleep on your stomach, you can put a flat pillow-roller cushion or a blanket, and if on the side - then between the knees - the load on the knee joint will be less.

Pros, minuses and contraindications to sleep on hard surfaces

To sleep on the floor is useful (if there are no contraindications) - and that's why:

The posture is corrected - on the solid surface, the spinal line is maintained smooth - it occurs under the weight of its own body;

Improved sleep quality - an inappropriate mattress and an uncomfortable pillow - frequent causes of bad sleep. Of course, the rigid surface does not guarantee that insomnia will pass, but it is worth trying. In a cool place, sleep is much better - the cold air ""walks"" by the floor, and warm turns out to the top. Especially it will be comfortable for those who sweats at night - the mattress absorbs part of the heat, heats up and often ""wakes up"" in the middle of the night;

A sleeping place remains clean - many microbes live in the mattress, and dust and dirt and dirt accumulate. With a rug or tatami such problems will not be - at least they are easier to clean than a bed;

Muscles are being worked out - on a too solid surface, the muscles serve - rolled out of one sleep posture to another can be compared with self-massage technique using a special roller;

The blood circulation is improved - orthopedic mattresses with the effect of memory limit the movements and ""lock"" the body in one position overnight - from here and stiffness in muscles, pain and clips. On the semi-alone body weight is distributed evenly - the blood is circulated fully.

The rejection of the habitual bed in favor of a hard surface is not suitable for everyone - there are its cons:

The first time will be uncomfortable - with inappropriate it is unlikely to get to sleep quickly, especially if you sleep on the side;

There is no guarantee that the posture will straighten - the spinal column has bends, it is not perfectly even, but an overly hard mattress, as is too soft, does not support its natural position. At night, it is important to rest - long physical overvoltage can lead to muscle weakness (condition when the muscles stop working);

Back pain in the back can intensify - orthopedic mattresses are well adjusted for bends of the body, and there is no solid floor - space remains between the surface and the body. Without a bed with zonal support (spring block), the entire load goes on the hips, anchor, hands, blades and pelvic bones;

Pressure on joints and soft tissues can hit those who have diseases of the musculoskeletal system (arthritis, arthrosis, osteoporosis). And the dust on the floor can provoke a reaction in allerges;

There is a risk of catching - to transfer it to people with anemia, diabetes and with weakened immunity - the cold floor (if it is without a heating function) can further weaken the immune system, and then the infections will easier to pe*****te the body;

In these cases, it is impossible to sleep on the floor

Pregnancy - the load on the spine during this period and so large, and even more voltage can lead to displacement of intervertebral discs. Sleeping in this position will be uncomfortable, and get up and go to bed.

Obesity is the more weight, the greater the load on the spine, muscles, joints and soft fabrics. You can sleep with an extra weight to sleep on hard with the permission of the doctor, but still not on the naked floor.

Older people - with the age of joints are easier to be injured, the bones break, and the skin becomes thinner - bruises and breakdowns can appear from a long-term contact with a solid surface.

Health problems - osteochondrosis, scoliosis, radiculitis, intervertebral hernia, arthritis, diabetes, anemia, obesity, postoperative period - all this is also a reason to postpone experiments with sleep on a solid surface (or consult with a doctor).

In general, sleep on the floor is a personal choice of each. Sleep quality depends not only from a convenient mattress or its absence, but also from the type of physique, age, health and image in life as a whole. Whether it will benefit or vice versa, it is impossible to hurt, it is impossible to predict - the best way to make sure about it - check.

The more we sleep, the less likely to get sports injury. We understand research

"A normal healthy sleep in a volume of at least 7 hours per day has a positive effect on the longevity and health of the cardiovascular system. And also - reduces traumatic athletes.

The study published in 2014 in the journal of Pediatric Orthopedics was devoted to the relationship between the duration of sleep and the trauma of young athletes. The work tracked the frequency of injuries among 112 students engaged in different sports, taking into account the following data: the duration of sleep, sports time, the volume of force training. As a result, a direct dependence was identified that with a decrease in sleep clock sharply increased the likelihood of injury:

In the journal of sports medicine, a review was published on a wider range of probable causes and consequences. A research team from Tawon University proved that sleep reduction inhibits testosterone production and growth hormone and increases the level of cortisol. It can weaken the muscles and make an athlete more susceptible to injury. Sleepiness can also slow down the reaction and lead to loss of attention, which, in turn, can increase the risk of injury in contact or sports, requiring special attention and coordination (acrobatics, jumping from springboard, gymnastics, freestyle skiing and snowboarding).

In 2017, the Scandinavian magazine of Medicine and Science in Sport published a great research on the issues of sports injuries. Scientists viewed a wider range of risk factors: self-esteem, stress, nutrition and sleep.

The study took part 340 athletes from different sports: mild athletics, sports orientation, handball and ski species (ski racing, high-speed descent, freestyle). As a result, it turned out that during the year 19% of respondents did not follow the recommendations, and 20, 39 and 43%, respectively, were observed.

Two main outputs were made. First, athletes who slept at least eight hours a day, 61% were rapidly injured. Secondly, compliance with the established nutritional regime (including sufficient consumption of fruits, vegetables and fish) also reduced trauma by 64%.

The 2019 study has confirmed the previously voiced concerns: young athletes who have spawned less than 8 hours a day, received injuries 58% more often.

As we can see, sleep for an athlete is the basis for restoring and maintaining performance in the training process. The neglect of sleep leads to a deterioration of the hormonal background and sharply increases the likelihood of injury.

It is impossible to prevent all week, and then sleep over the weekend. Our body does not like to be borrowed, so you take a dream for at least 8 hours a day to stay healthy and concentrated in training and competitions.

Do you need creatine for training? How to take it right? We understand the properties of the additive

"He really gives the effect that promises. Science has proven.

Food additives tightly entered the diet of athletes as a professional level and amateur. One of these additives, creatine, promises us an invisible increase in strength, muscle mass and endurance in training. Let's figure it out if it is, and that science speaks about properties, benefits and harm from its use.

What is creatine

Creatine is an organic compound (nitrogen-containing carboxylic acid), which is found in the vertebral body. It participates in the energy metabolism of cells, primarily in the muscles and brain tissues. Also, some studies have shown that this substance can supply the brain of energy, showing a neuroprotective (protective) effect against encephalopathy (dystrophic change in brain tissues, followed by a violation of its operation).

In natural products, creatine is contained in fish and red meat. In addition, it is produced in the form of food additives. It is mainly used by athletes in order to improve performance in strength training, due to which the muscle mass increases. Also designed to help elderly people in the fight against muscle exhaustion.

This nutritional supplement is not doping and permitted by the International Olympic Committee and the World Anti-Doping Agency.

What gives creatine athletes

The human body actually produces its own creatine (the kidney and the liver are responsible for it) after eating meat. The muscles convert creatin into creatine phosphate (high-energy compound), which during the reaction is converted to adenosine trifosphate (ATP, actually energy) and is used by the body for explosive exercises (for example, sprint acceleration or rods).

Important moment: the body can accumulate creatine, which is why the corresponding diet (red meat and fish) or the addition of additives allow you to perform more power exercises and progress in classes.

Most of the creatine in the human body is in skeletal muscles (95%), the remaining 5% are distributed in the blood, brain and other tissues. The average amount of creatine stored in the body is approximately 120 mmol / kg of dry muscle mass. However, by receiving additives, this value can be increased to 160, that is, by a third.

The benefits of raising the level of creatine:

an increase in the number of repetitions in power exercises;

an increase in the number of sprint accelerations in athletics (important indicator in the training of runners for short distances);

improving athletic indicators (energy level rises, productivity increases, improve adaptation to training loads);

reduction of losses of muscle mass after operations;

Improving the function of the heart when performing exercises in people with coronary heart disease;

Reducing the risk of heart disease by reducing cholesterol levels.

The fact that creatine is synthesized in our body does not mean that it can be uncontrolled in the form of additives - observe the dosage. It is also necessary to take into account that there is a large number of producers of the BAA in the modern market, so before buying and starting reception, you will definitely consult with a specialist or an experienced trainer.

Possible side effects of creatine include:

increase weight;

alarm;

labored breathing;

fatigue;

heat;

headache;

kidney problems;

nausea, vomiting;

rash;

stomach upset.

How to take creatine

For a set of muscle mass

Back in 1985, an article on the assessment of different dosages was published in the journal of applied physiology when taking creatine. As a result of the analysis of the results obtained, the following food additive use was proposed for a set of muscle mass (this technique is still used):

The loading phase: 4 times a day of 5 grams for 6 days. Allows you to increase creatine stocks in the body by 20%.

Supporting phase: In the future, it is enough to take 2-3 grams per day to maintain the reached level of stocks. Later releasesPassed that this dosage can be increased to 3-5 grams.

Alternatively, a dosage calculation formula was proposed based on the athlet weight:

0.3 grams of creatine per 1 kg body weight per day, divided into 4 equal portions

The study showed that the reception of a lower dose (3 grams per day) for 28 days increased the overall stock of creatine in muscles on the same 20% as if quickly downloaded for 6 days. However, the 28-day phase does not allow to implement ergogenic (increasing performance) the advantages of creatine as long as the muscle tissue is completely saturated. That is, you can fully train on the selected program only when the necessary level of stocks will be reached at the end of the month.

Another study showed that additional consumption of carbohydrates or carbohydrates and proteins together with creatine helped longer maintain reserves in tissues.

After stopping the intake of creatine, its reserves in the muscles are returned to the initial level after 4-6 weeks. The achieved power and volumetric indicators (except for excess water in the tissues) are saved.

For dryshka

Due to the fact that the intake of creatine leads to the accumulation of excess water in the muscles and an increase in body weight, it is impractical in the phase of drying. Also during this period it is worth limiting the reception of rapid carbohydrates for the same reason.

With exercises on the development of endurance

In sports for the endurance of creatine, there will be no advantage, moreover, the increase in body weight will negatively affect the economy of the athlete. The only type of cyclic disciplines (running, cycling, swimming), for which the intake of creatine will be appropriate, is a sprint, since there are short load intervals with high intensity.

How to take creatine with other additives

With caffeine

Despite the fact that excessive coffee consumption (2-3 cups per day) and caffene-containing drinks (250-300 mg of caffeine) leads to polyuria (increased urine formation and the corresponding water loss by the body), the results published in 2017 in the force studies journal and a set of form, did not show the reduction of power indicators in different groups of tests tested creatine. Based on this, the reception of caffeine (in the form of coffee or food additives) should not affect the effect of intake creatine, both in the process and after the loading phase is completed.

With carbohydrates and heiners

Studies show that the reception of carbohydrates together with creatine during the loading phase can improve the absorption of the food additive with muscles. However, this requires a significant amount of carbohydrates - approximately 100 grams per serving of creatine. Accordingly, you can use both clean carbohydrates and heiners. Be sure to consider increasing calorics with such a combination of components.

With protein

In a study published in 2000 in the journal of applied physiology, it was proved that the joint taking of protein (50 grams) and a little less carbohydrates (47 grams) also improved the absorption of creatine in the load phase. But, as in the case of pure carbohydrates, do not forget to calculate the general calorie content of the diet.

With BCAA complexes

Various studies have shown that the mixing of the Amino acids of BCAA and Creatine does not adversely affect the body. Almost all preparation additives combine these two components (amino acid and carboxylic acid).

However, many professional athletes and personal coaches recommend independently controlling the ratio of additives instead of using ready-made complexes in which carbohydrates and caffeine are contained.

How to choose creatine

There are many forms of sports nutrition in which it is easy to get confused. Experts and consultants Men's Health pay attention to the following key points:

Always buy Creatine Monohydrate. ""Most studies show that the monohydrate is the most secure and effective form of additive,"" says Andrew Jagim, director of research in sports medicine in Mayo Clinic Health System. Other forms (ethyl ether, hydrochloride, magnesium chelate) are more expensive and do not have the same evidence base.

Prefer the powders instead of tablets. ""Creatine is unstable in a liquid solution,"" explains Dr. Jagim. ""Therefore, you need to mix the mixture well and quickly use.""

Look at the sale micronized version (small crystal powder). No matter how much you have changed the mixture, creatine is so easily dissolved in the shaker. Mike Russa, Men's Health Power Advisor, notes: ""This is the same additive, but split into small particles. Such powder is better dissolved in water. ""

Do not overpay for trace elements. In some embodiments, food additives may be contained sodium, magnesium and other electrolytes. According to Dr. Roll, they do not strengthen the effect of creatine: ""If you need electrolytes to maintain performance during training, simply mix the monohydrate powder with isotonic.""

Top Creatine Manufacturers

The market has a large selection of manufacturers of additives, so before buying consult with a specialist or personal trainer. According to the ranking of the site Bodybuilding.com (according to customer estimates), the top list looks like this:

RSP Nutrition - Creatine Monohydrate. The product from RSP is made of micronized monohydrate; It is optimized for better assimilation by the body, compared with competitors accumulates less water in the muscles. One of the best creatins for consumption before and after training.

Evlution Nutrition - Creatine 5000. According to the manufacturer's application supports the growth of muscle mass, improves performance, improves the power indicators, supports the production of adenosine trifhosphate (ATP).

Muscletech - Platinum Creatine. Pure monohydrate in micronized form. Presented in the dosage of 5 grams, which, with a constant reception, the muscles will saturate during the month and will contribute to an increase in force, productivity and muscle volume. Muscletech is a popular brand that has trusted by many professional athletes.

Kaged Muscle - C-HCl Creatine. The company has developed and patented its own form of creatine hydrochloride with better solubility in water.

Bodybuilding.com Signature - Signature Creatine Monohydrate. Sports product of own production. Dosages of 5 grams of a pure monohydrate shredded to micronized powder for maximum absorption and maintenance of muscle strength and performance during training.

The use of creatine according to research does not carry dangerous side effects. Also, the additive is not doping and is not prohibited by world and national authorities. The recipe and the order of admission are studied by decades, so when dosage, you will get a useful effect. Nevertheless, we recommend in advance to consult with a specialist to avoid individual intolerance to components and overdose.

Calculator Calorie: Why is it needed and how to use it? How to calculate your calorie rate to lose weight or gain weight?

"Calorie calculator determines how many calories per day need to consume a person taking into account its metabolic level. Not all such calculators are equally good. Their accuracy depends on which formula is based on. Now there is the right one, and we tell me how to use it to lose weight or vice versa - gain weight.



How to use the calculator data

So, you received a number - a calorie rate that should consume during the day. The question remains: what to do with it?

With this data, you can solve two pressing problems: lose weight or gain weight. Important: All further advice apply only to people without health pathologies and without obesity - in these cases, any diet should be agreed with the doctor.

If your goal is to lose weight

You can lose weight by increasing the physical activity and creating a calorie deficit: it means there is less than you need per day, but to move more. Then the body begins to spend energy reserves from fat. The calorie deficit method underlies the universal Slimming System of the National Health Service of Great Britain.

The main rule of weight loss with the help of a calorie deficit - the daily rate of energy should not be lower than your level of basal metabolism. In general, it is relatively safe to adhere to a deficit of 10-20%. It is recommended to start with 10% and further gradually increase the deficit if necessary.

For example, a woman is 27 years old with an increase in 165 cm and weighing 55 kg, which 3-5 times a week goes to training and in general leads an active life, you need 1984 kokalorius per day. If she wants to lose weight, to begin with, it can be reduced by the rate of consumption up to 1785 kcal - it is minus a tablespoon of mayonnaise or a piece of bread per day, or half of the burger or donut without filling. At the same time, in the desire to lose weight, it is impossible to drop below 1280 calories (1984 kcal divided into the medium activity coefficient of 1.55) and it is desirable to adhere to the principles of healthy nutrition, for example, to eat at least five portions of vegetables or fruits per day - about 80 grams each.

Purpose - gain weight

If you need to gain weight, for example, in bodybuilding, it is necessary to create a calorie surplus - add them to the daily diet. The novice bodybuilders are recommended a supernergetic diet + 10 + 15% by daily diet. This allows you to score up to 2% of the current body weight per month.

For example, a man of 26 years with a weight of 70 kg and an increase in 176 cm with an average level of activity requires 2696 kokalorius per day. If adding 15%, there will be 3100 kcal. That is, approximately 400 grams of chicken breast or one burger can be added to the daily menu. The second option will also help to gain weight, but when regular use can adversely affect health. By the way, professional bodybuilders are not recommended to rely only on the calorie surplus. It is important to strictly take into account the ratio of proteins, fats and carbohydrates.

If you do not need to lose weight, nor gain weight, then stick the calorie norms you need and try not to forget about the basic healthy nutrition rules: for example, it is recommended to receive no more than 30% of the total calorie rate per day, including no more than 1 % Calories from the clubs, from free sugars you should also receive no more than 10% of energy.

An example of a daytime diet in dishes and kilocalories

Calculator data should be rechecked and recalculated

Calculator data are not constant: if you started moving more, play sports and regularly train, then the body will need more energy and more calories. And if, for example, they left the office to ""remotely"" - the level of physical activity will decrease.

In general, most people tend to overestimate him. But because of this, the calorie rate will also get overestimated - as the calculator will assume that you spend a lot of energy. It is not suitable primarily for those who want to lose weight, but even if you want to gain a lot, it is better to have a closer value to the truth. Save the calculator to bookmarks and return to it to recalculate your performance. If you have a sitting job, and you are only occasionally doing some exercises, then this is the first level of load - minimal. In this case, the activity coefficient is 1.2.

If the work is still sitting, but you walk quite a lot, actively walk with the dog several times a day, ride a bike / skiing or trained at home 1-3 times a week, then your coefficient is 1.375.

In the case of medium activity, the coefficient is 1.55. Regular training is 3-5 times a week - not 15 minutes, but full-fledged, on the hour. In addition, you are still cooking and retaining at home, go a lot on foot or walk and play with your child.

If you train 6-7 times a week or your work is associated with physical labor - the coefficient of 1,725.

As examples of maximum load - severe physical work or training 7-10 times per week (coefficient of 1.9).

How does the calorie calculator work

The calculation is based on the concept of basal metabolism (BMR) - this is the amount of calories (energy), which the body spends in a state of rest to maintain the functioning of the body: respiration, operation of the gastrointestinal tract, blood circulation, thermoregulation, nervous system operation. This value depends on age, gender, growth and weight - these indicators usually need to be administered when using calorie calculator.

There are 4 of the most common formulas for calculating the base metabolism: these are Harris-Benedict, Miffline-San Säora, Owen and WHO / FAO / UNU (World Health / Food and Agriculture Organization of the United Nations / University of UN). The most reliable today is the formula of Miffline-San Säore:

BMR for men = (10 × weight in kilograms) + (6.25 × growth in centimeters) - (5 × age in years) + 5

BMR for women = (10 × weight in kilograms) + (6.25 × growth in centimeters) - (5 × age in years) - 161

Mark Miffline and Satiko San Säor did not themselves developed the formula. In 1990, a group of scientists under their leadership enhanced the initial formula of Francis Benedict and James Harris, which they were created back in 1919.

Basal metabolism does not even take into account the minimum level of physical activity like a sedentary work at a computer. That is why in the calculator, the base metabolism indicator is multiplied by the physical activity coefficient - to adjust the result under your lifestyle.
