Consequently, training on an empty stomach contributes not only to the normalization of metabolic processes, but also to weight loss. Although there is an opinion that the timing of cardio or vigorous exercise does not matter. Therefore, the issue needs to be addressed.

The body after waking up

In the morning, after sleep, the body's reserves of glycogen and insulin in the blood are depleted. Why is this information important? Insulin slows down lipolysis, that is, fat breakdown, therefore, a person loses weight more slowly, and cholesterol accumulates in his blood. When glycogen is low, the body has to use its own energy (from fat reserves), which is not prevented by small amounts of insulin. Other processes in the body at this time reflexively slow down out of the principles of self-preservation.

At the same time, in the morning there is a high level of growth hormone, released as a reaction to the lack of food. It is this substance that accelerates fat breakdown. At the same time, insulin and growth hormone are interconnected - they slow down each other’s synthesis. Therefore, the morning hours are the optimal solution for those who want to burn fat reserves and lower cholesterol levels.

Training in the morning on an empty stomach: is it possible?

Early training on an empty stomach involves playing sports before breakfast, when a person runs, lifts dumbbells, etc. The effectiveness of such exercises is based on the expenditure of the body’s own resources to produce energy, in return for carbohydrates not supplied from outside. Exercising in this mode is useful for those who want to lose weight. For those who are focused on gaining weight, exercising on an empty stomach will allow you to slightly break down fat and dry out muscle tissue. The technique allows you to ultimately obtain the required muscle definition by resuming training on a full stomach.

Despite the apparent benefits, there are limitations to fasted training. It is not recommended for diabetics or people with liver problems to get involved in technology as a therapeutic measure. If training is indicated, the sports program is selected individually with the approval of the attending physician. Sports activities on an empty stomach for the listed pathologies are indicated because with an increase in muscle mass and a decrease in the percentage of body fat, the effect of insulin on cells improves, making it easier to control diseases. But in order not to faint from hunger, it is still recommended to eat 2-3 apples and drink a glass of juice 1-1.5 hours before training. But you shouldn’t eat heavily, because when exercising on a full stomach, the body will work at half capacity due to the need to waste a lot of energy not on training, but on the process of digesting food. Besides, it's harmful.

Strength training and its effects

The effect of such exercises in the early morning and on an empty stomach is purely positive, if not aggravated. With the right approach and proper selection of the program, accelerated fat breakdown and a decrease in cholesterol in the blood will occur due to the consumption of one’s own fat tissue, instead of absorbed from the outside. But if abused, the opposite effect will be achieved. Energy will be extracted from muscle tissue, since against the background of exhaustion and lack of fat deposits there is nowhere else to take it from.

When fasting and strength training are combined, somatotropin, the “elixir of youth,” begins to be intensively produced, which helps build muscles, burn fat, and strengthen bones. At the same time, physical endurance increases due to a jump in testosterone levels, which accelerates the functioning of organs and prevents the occurrence of depression, fatigue, and lethargy. Thanks to early training, the efficiency of glycogen storage in muscles increases and endorphin is produced - the hormone of happiness.

Running and walking on an empty stomach

The peculiarity of early cardio without breakfast is the acceleration of metabolism, which continues throughout the next day.

In addition to effectively burning fat when running or walking on an empty stomach, the positive effects are:

• acceleration of endorphin production, which improves mood;
• ensuring quick awakening with the launch of all organs and systems at the same time;
• regulation of appetite throughout the day;
• establishing a circadian regime, thanks to which it becomes possible to quickly adapt and improve physical capabilities;
• acceleration of metabolism.

The effectiveness of a cardio session is judged by the ability to burn fat after training, that is, over the next 3-4 hours. However, it is important to exercise wisely on an empty stomach. It is better to run for no more than half an hour, and during the rest of the day, avoid feeling hungry. The best option alternation of aerobic and anaerobic physical activity is considered.

How to play sports correctly?

Based on the above, there are 2 types of physical activity:

• strength (barbell) - for building muscles;
• cardio (running, race walking) - increases metabolism, endurance and weight loss.

Both options are good, but only if the body has sufficient endurance. Otherwise, it is better to give preference to running or walking in the early hours, which helps release adrenaline into the blood and charge the body with energy for the whole day. But doing exercises based on the use of force is more effective in the afternoon, when fat reserves continue to be burned after running or walking.

It is equally important to choose the right load intensity and session duration. A fasted morning workout should not last more than 45 minutes or less than 30 minutes. The pace should be average. Otherwise, during training, the body will begin to consume carbohydrates rather than fats for energy. This is explained by an imbalance of oxygen coming in with inhalation and carbon dioxide coming out with exhalation. It is considered ideal to run at an average rhythm for at least 45-60 minutes in one cardio session.

To maximize the effectiveness of your early workout, it is important to reduce your carbohydrate intake the night before. This need is due to physiology. So, for the first half hour, the body uses carbohydrate reserves to get a boost of energy, and then begins to consume fat deposits. But you should not completely abandon carbohydrates in the evening. It is better to use them in the form of vegetables with a carbohydrate content of 3-6%. These include cabbage, beets, tomatoes, radishes, cucumbers, greens, pumpkin, carrots, and onions. But it is better to eat fruit in the morning and not more than 250 g per day. If it is absolutely impossible to run on an empty stomach in the morning, experts advise drinking a glass after getting out of bed warm water, after 10 minutes - a mug of warm tea or coffee without sugar.

A competent combination of effort work and running provides the following health benefits:

1. Disappearance of joint problems.
2. Increasing elasticity and improving the condition of blood vessels.
3. Acceleration of metabolic processes, weight stabilization.
4. Enrichment of bone tissue minerals, which is important in the prevention of osteoporosis.
5. Increased cell sensitivity to insulin.
6. Increasing the level of “good” cholesterol with decreasing “bad” cholesterol.

If, at the time of training, you feel intense muscle, joint, headaches, heart pain or compression in the chest, severe shortness of breath, or blurred vision, it is recommended to stop exercising. Dizziness and fainting are considered a dangerous condition. To prevent the disorder, you should run with a heart rate monitor. The device will monitor your pulse and alert you if any irregularities occur.

Is it possible to train on an empty stomach?

There is a theory that if you exercise on an empty stomach, it allows you to burn more fat and lose weight more effectively. Adherents of this theory explain that in the morning, on an empty stomach, the content of glucose and insulin in the blood is lower than after breakfast, and during training this allows you to quickly deplete the reserves of the former, and the low level of insulin does not prevent the effective breakdown of fats.

As a result, the effectiveness of such training on an empty stomach in terms of energy costs is more effective. This is true and numerous studies confirm this. The main question is whether fasting training has a long-term effect and does not cause harm to the body as a whole?

It doesn’t matter how many calories you burned for a specific workout, what is much more important is the overall energy balance, the balance of calories received and burned per day.

The American Journal of CLINICAL NUTRITION published in 2014 (in fact, there are a lot of studies, I just chose the most complete and with free access to the full text) the results of a large randomized study on the effect of breakfast on general metabolic processes in the body.

The total energy consumption of our body consists of three main components:

1. BX;
2. regular thermogenesis (there is also food thermogenesis);
3. energy consumption for physical and intellectual activity.

As a result of this study, the following results were obtained:

• Total energy intake averaged 2730+/-573 kcal/day for the breakfast group versus 2191+/-494 kcal/day for the non-breakfast group.
• At the same time, energy consumption for general metabolic processes was almost the same in both groups: 1453+/-209 compared to 1452+/-179 kcal/day.
• But in the breakfast group, thermogenesis component of energy balance was significantly increased: 1449+/-666 kcal/day in the breakfast group versus 1007+/-370 kcal/day in the non-breakfast group.
• The group taking breakfast also spent slightly more on physical activity than the group abstaining from breakfast: on average 492+/-227 kcal/day versus 311+/-124 kcal/day for the group.

Therefore, we come to the conclusion that: Regular consumption of breakfast leads to a significant increase in total energy expenditure through an increase in energy expenditure for thermogenesis and physical activity. This is explained by the fact that breakfast can influence spontaneous behavior in a structured physical activity. A higher blood sugar level (blood glucose concentration 7.6+/- 1.2 mmol/liter compared to the fasting group 6.5+/-1.0 mmol/liter) signals the body to actively consume energy. It is noted that over time there is no metabolic adaptation to breakfast.

This study clearly shows that there is indeed a correlation between eating breakfast and total daily energy expenditure: the average daily energy expenditure with breakfast is on average 539 kcal/day more than without it.

Regularly eating breakfast significantly increases the body's total energy expenditure over the next 24 hours.

Another study published in the Journal of Strength and Conditioning Research stated that: there were more high levels cortisol, myoglobin, and creatine phosphokinase levels after exercise compared with those who consumed protein or carbohydrate mixtures before exercise.

High blood levels of myoglobin and creatine phosphokinase most often indicate muscle damage. In severe cases, this can lead to a condition known as acute skeletal muscle necrosis, which in turn can lead to acute kidney failure.

Eating some protein and carbohydrates before exercise (such as a carbohydrate-protein shake) can reduce the amount of muscle damage caused by intense exercise.

Again in 2005, The American Journal of CLINICAL NUTRITION published a study on the effects of eating or not eating breakfast on overall energy balance, insulin, and lipid concentrations in healthy women:

• Women who exercised without breakfast showed a deterioration in postprandial (two hours after eating) insulin sensitivity. That is, the area of ​​the insulin response curve to a test meal in women having breakfast before training was significantly lower than in women training on an empty stomach. Cholesterol levels in the fasting group were also significantly increased.

Insulin sensitivity is very important for proper absorption of nutrients, and impaired insulin secretion is a long-term risk factor for a number of serious diseases, such as coronary artery disease, stroke and type 2 diabetes.

conclusions

• Regular exercise on an empty stomach can trigger insulin resistance and, as a result, become a risk for developing certain chronic diseases.
• Exercising on an empty stomach, and especially performing high-intensity workouts with low blood glucose levels, firstly, will not allow you to perform this workout as effectively as possible and, accordingly, such a workout will not be developmental; Moreover, training on an empty stomach can provoke an increase in the number of muscle injuries; secondly, training on an empty stomach can cause a rapid drop in blood glucose levels much lower than usual and provoke a dangerous state of hypoglycemia.
• It is best to take an easily digestible meal (in a minute) or drink a quick protein (preferably hydrolyzed) or carbohydrate shake (30 minutes) before exercising, which will allow you not only to increase the effectiveness of your exercise, but also to maintain your health.

Working out on an empty stomach: what are the benefits?

Many people believe that it is wise to exercise when there is something in the stomach. Allegedly, this is food and will be the very energy that will be wasted during training.

Information on training on an empty stomach

The Hodge Twins, as well as many modern athletes, preach training on an empty stomach. And you know what they say: “Such training is much better.” You are more concentrated and have more energy, your brain is not filled with unnecessary tasks about digesting and assimilating what you ate an hour or two before going to the gym.

But is it possible to exercise on an empty stomach and what benefits do you get from it? Let's figure it out.

Benefits of Fasted Training

Usually train on an empty stomach:

• in the morning on an empty stomach (last meal was last night),
• throughout the day when you use intermittent fasting.

The state of hunger itself means a state of low blood glucose. This best conditions to produce your own growth hormone. Increased production of this hormone increases the rate of fat burning (with a calorie deficit), as well as anabolic processes.

There is a system of intermittent fasting. Her standard protocol is a 16 hour fast, 8 hour eating window. For example, a day could be scheduled like this:

9.00 tea, coffee or plain water

11.00 strength training

15.00 meal (first meal of the day)

19.00 meal (second of the day)

23.00 meal (last of the day and the hunger phase begins until 15.00 the next day)

This scheme is not an axiom, the variability here can be very wide, the main thing is not to change the essence of 16/8 and keep yourself hungry for several hours before and after training.

Visual results intermittent fasting and training

Digestion is a long process (as already mentioned in the article about protein absorption). Digestion of food itself can take up to 6 hours, and leftover food can linger in the intestines for hours. With a high degree of probability, by the time of training (as in the example at 11.00), yesterday’s dinner (23.00) is still digested and supplies the person with nutrients. There will be no weakness or malaise if you skip breakfast.

Another argument in favor of training on an empty stomach is the fact that after eating you feel sleepy. The peculiarity of this phenomenon is that carbohydrates entering our body provoke the production of serotonin, the property of which is relaxation. nervous system. It is easier for a person to fall asleep with a full stomach than with an empty one. That is why training on a full stomach you will "sleep". Not in the literal sense, of course, but the performance and power of the body will be significantly undermined by the processes of digestion and assimilation of the food that is in the stomach, as well as by the action of serotonin.

This effect lasts approximately 1 to 3 hours after eating (it varies for each person). So, 3-4 hours after the last meal, the stomach is practically empty, all the main processes of assimilation are already coming to an end. Blood glucose levels decrease, and these are optimal conditions for the production of anabolic hormones, so it's time to go to training.

Our body is a survival mechanism. You will never “go into catabolism”; if you don’t eat for 4 hours, the body will not start “eating” itself. Get rid of these myths.

Exercising on an empty stomach means promoting fat burning (but only in a calorie deficit). The body will use fat as an energy source, but only when you feel hungry.

If you correctly observe the caloric content of your diet, as well as the ratio of carbohydrates, proteins and fats, then you will not have any problems with training on an empty stomach. Your glycogen stores in the liver and muscles will be completely clogged. And since there are glycogen reserves, there will be no weakness, the workout will go no worse than usual.

Your hands will not shake, you will not feel unwell or faint, because... Liver glycogen will maintain the blood sugar level necessary for your body.

What problems can arise when training on an empty stomach?

Since you have decided to train on an empty stomach, then know that states of weakness and loss of strength can be caused by the following reasons:

The first is that you have problems maintaining blood sugar levels.

This is a malfunction of the body. If, after skipping one meal, your hands begin to shake and you really feel unwell, then you should consult a doctor. However, this problem may be caused by the following.

The second is insufficient consumption of carbohydrates in the diet.

Carbohydrates are the most accessible energy for our body. The problem here may arise because people mistakenly call carbohydrates the culprits of excess weight, cutting down their amount to an impossible extent, thereby reducing the total calorie content. However, caloric intake is the main tool for managing your weight.

By removing carbohydrates from your diet to low amounts, you reduce glycogen levels in your muscles and liver. All that follows from this:

The amount of carbohydrates in your diet should be % of the daily calorie content (read how to distribute calories correctly here). By lowering these numbers below, you deprive yourself not only of energy for training, but also of energy to maintain the normal functioning of all body systems.

By consuming a normal amount of carbohydrates per day, you will supply your glycogen depots with reserves. Muscle glycogen will wait in the wings until your next workout, and liver glycogen will maintain healthy blood sugar levels.

If you follow the norm for carbohydrate consumption, you can even eat the entire daily dose in one sitting - although this volume will take a long time to digest, it will be completely absorbed and stored in glycogen. You will not feel tired or lack of energy; in addition, this will once again prove that the frequency of meals does not matter if the calorie content and the B/F/U ratio are correct.

Third - You are looking for excuses.

“I didn’t eat well, so I didn’t train well.” Nonsense! Here's the scientific basis for you. An experiment on Muslim athletes during the Ramadan fast (http://www.jissn.com/content/10/1/23) showed that the functionality of our body does not change in any way during short-term fasting.

Conclusion and conclusions

You can train on an empty stomach, and this even has its advantages. In addition to the mental and physical state of lightness and vigor, your hormonal system is open to the production and action of anabolic hormones that you release during training.

A man is a hunter by nature - active, lean and agile. By the time of the new mammoth hunt, he is hungry, and this state has always stimulated the body in every sense. Try using a state of hunger before training and write about your feelings in the comments.

Sports on an empty stomach. All the benefits of fasting

We all come to understand that we need to eat less. This long and thorny path is strewn with incomprehensible experiments with vegetarianism, a raw food diet, separate meals and other things. A special practice is fasting. The thing is interesting and useful in every sense, especially in the context of sports.

Which is better?

How do you prefer to train? On an empty stomach or after a solid meal? I personally am only able to move in the early morning, before breakfast. Many people, on the contrary, can function normally only by eating heavily.

The debate about the best way to exercise will probably never go away. Fans of exercise on an empty stomach are squabbling with those who like to snack one more time, and it seems that the truth is still far from true. Today we will try to give a definitive answer to the question of how to exercise most effectively.

It's time to debunk old myths about food and exercise.

It is, of course, difficult to give a definitive answer. Everyone is different, and everyone achieves the best training results in different conditions. Telling a person how he should exercise is kind of like telling him what time of day to work out or what diet to follow. Everything is too individual. But there are a number of myths that people continue to believe.

Contrary to popular belief, research shows that snacking during the day does not speed up metabolic processes, skipping meals will not automatically make you fat, and exercising on an empty stomach will not invalidate your workout results. In reality, periodic meal skipping, also known as intermittent fasting, dieting alternative nutrition or the longevity diet can be incredibly beneficial.

So let's start with the good. For example, from the fact that handsome Hugh Jackman, preparing for his next role as Wolverine, practiced intermittent fasting in order to build up muscle mass. Why did he choose this particular diet? The fact is that it triggers a chain of hormonal changes that are beneficial both for building muscle mass and for burning excess calories.

Exercising on an empty stomach has two significant benefits

1. Increases insulin sensitivity

Let's talk very simply. When we eat, the body produces insulin to help absorb nutrients. The hormone then redirects sugar from the blood to the liver, muscles and subcutaneous fat to be used for energy later. The problem is that the habit of eating too much and too often makes us more resistant to insulin, that is, it reduces sensitivity. In medical practice this is called insulin resistance. Low insulin sensitivity increases the risk of cardiovascular disease and cancer, and also makes it much more difficult to lose weight. In short, it interferes with life with terrible force.

Reducing the frequency of meals is a good way to solve the problem of insulin resistance. The body produces insulin less frequently and, accordingly, becomes more sensitive to it. Blood flow to the muscles improves, it becomes easier for us to lose weight, and the effects of an unhealthy diet are curbed.

2. Action of the hormone somatotropin

Somatotropin is an almost magical elixir of youth that helps the body build muscle tissue, burn fat, strengthen bone tissue, improve physical function and prolong longevity.

Along with regular training and good sleep, easy post is the best way increase the level of somatotropin in the body.

One study found that after 24 hours of fasting, growth hormone levels in men increased by as much as 2,000%, and in women by 1,300%! The effect wears off quickly, so there are good reasons to fast regularly in order to constantly maintain the level of somatotropin, which has such a wonderful effect on our body.

Fasting and sports

When talking about beneficial hormones, we cannot ignore testosterone. It helps increase muscle mass and reduce body fat. In addition, it increases the level of physical strength, energy and libido, helps in the fight against depression and heart problems in both men and women. Fasting itself has no effect on testosterone. But there is an amazing way to force the body to produce more testosterone and growth hormone at the same time, thereby creating ideal conditions for building muscle mass and burning fat: fasting + active sports!

Exercise, especially intense exercise that targets multiple muscle groups (compound exercises like barbell squats), causes large spikes in testosterone. This is why it is useful to combine exercise and fasting. Numerous studies have shown that working out while fasting is a great way to build muscle and improve insulin sensitivity. This approach is effective not only because of hormonal reactions, but also because it helps the body absorb nutrients from food much more actively.

In short, exercise on an empty stomach helps proteins, fats and carbohydrates to be stored as fatty tissue in the smallest quantities. It has been found that people who actively exercise while fasting lose weight at a much greater rate (possibly due to increased levels of oxidative enzymes).

Such training teaches your body to use energy more efficiently and not waste it, and increases the efficiency of glycogen storage in the muscles. Periodic “fast training” further improves the quality of regular ones. Some studies have also shown that "fast training" can significantly improve athletes' endurance, which is measured by the ability to take in and use oxygen during exercise, and is a pretty smart way to measure exercise.

Not everything is rosy, of course.

It would be dishonest to gloss over the fact that not everything is rosy. Some studies have shown that exercising while fasting results in impaired performance. True, they studied mainly such traditional fasts as Ramadan, which does not allow the consumption of liquids (which is not recommended for athletes). Even the fact that most people eat before playing sports already suggests that sports after eating already gives good results. Heck, there are even studies that show that eating before workouts can lead to fewer calories consumed throughout the day. But all this does not in any way cancel the undeniable benefits of periodic training on an empty stomach.

So, if you want to try working out on an empty stomach. ↓

Action plan

We understand perfectly what you are thinking right now. Something like this: “Screw it, I won’t be able to withstand the stress without eating anything!” First, let's have a little more faith in ourselves. You can do much more than you think, you just need to arm yourself with the right attitude. Secondly, we will give some simple tips that will help you master this diet more painlessly:

1. You can drink more than just water. Don't be afraid to break your old habits and get energy from black coffee, tea, caffeine tablets, creatine and other non-caloric substances.
2. Stop fasting whenever you feel like it. Many people prefer to eat immediately after training, after a short fast has already had its effect. It doesn't make much difference if you extend your fast. Even if you exercise in the morning and don't eat until the evening, the wave of hormonal changes will last throughout the day and prevent muscle loss. No matter what you decide, your body will always support you.
3. Eat as much as you want. Notice we didn't say "eat as many calories as you want." After all, it is not at all necessary to eat a lot of food.

And finally

There is a habit - this is probably the most durable human habit. We are all human, we are all human, our habits are us. Fighting the habit of constantly eating something is a noble, but ungrateful thing. This is terribly difficult, especially for those people who have spent N amount of time learning to eat regularly and at the same time. It's true: intermittent fasting takes time to get used to. Our body must get used to the fact that it will not receive food as often as before. This uncomfortable feeling goes away over time, but if you feel that this way of eating is not for you, then there is no need to continue. Just don't be afraid to try.

Exercising on an empty stomach: benefit or harm?

We have already talked about how to properly tune in to a new day in the morning in the article - How to get ready to lose weight in the morning. Well, here we’ll talk about such a thing as organizing training on an empty stomach. To draw the right conclusions, we need to touch upon the processes of the human body that occur from the moment it awakens.

Processes in the human body after waking up.

When we wake up, our glycogen stores are depleted and our blood levels of insulin are low. Let me remind you that insulin affects the catabolic process; the higher the insulin, the more lipolysis, that is, the breakdown of fat, slows down, and we lose weight more slowly.

When glycogen is low, the body uses energy from its own reserves and low insulin does not interfere with this process. But we should not forget that the instinct of self-preservation is not asleep, which means that all processes in the body are slowed down.

On the one hand, the body on an empty stomach is able to burn not the calories eaten for breakfast, but its own fat reserves, but for the purpose of self-preservation this happens very slowly.

Blood sugar is also low, this is confirmed by low performance on an empty stomach, sometimes even dizziness and weakness. But many people do not feel this discomfort and can get by with just a cup of coffee or tea until lunch. More on this later, now back to our processes.

In addition to low insulin and sugar in the morning, we have high levels of growth hormone, what causes this? The fact that after an overnight fast, growth hormone is released as a reaction to hunger. And we know that growth hormone increases the catabolic process (breakdown of fats). The hormone insulin is opposite to growth hormone, that is, the production of one hormone slows down the production of the other.

So, having drawn conclusions, we can say that the morning, when you have not yet eaten, is the optimal time for burning fat reserves.

How to exercise on an empty stomach and not harm the body?

As we already know, there are two main types physical activity strength and cardio.

Strength training is mainly used to build muscle mass, and cardio training is used to improve metabolism, increase endurance and lose weight.

If you exercise on an empty stomach, it is better to choose a cardio load, since it has been proven that this type of exercise promotes the release of adrenaline, which enters the blood during exercise and triggers the breakdown of carbohydrates and fats for use as fuel.

I don’t think that you can exercise with a barbell or dumbbells on an empty stomach, for this you at least need strength and vigor, but running or doing aerobics in the morning is the best thing.

Scientists have proven that it is better to do strength training in the afternoon, since after such stress the muscles continue to burn calories for some time.

Amount of load.

The intensity of the workout is also important. To get maximum results from fasted workout, you need to train at a medium pace, not at a high pace, and for at least 45 minutes.

The higher the intensity of the workout, the more the body will use carbohydrates rather than fats as energy, since the ratio between inhaled oxygen and exhaled carbon dioxide is disrupted. Therefore, the duration of the workout is important, not the high pace.

Whymin, this is the time when the body releases its reserves and does not try to preserve itself. There is no need to overdo it, do not forget that physical activity is a load that primarily falls on the heart muscle and vascular system; there is no need to subject them to terror once again.

The amount of carbohydrates consumed.

There is another important factor that will make your weight loss and training in the morning more effective, this is reducing the consumption of carbohydrates in the evening. Why is it important? When we spend our energy during physical activity, the body takes energy from carbohydrates for the first 30 minutes, and then uses fat reserves. That's how it works human body in order to survive in the extreme situations. But if we prepare our body in the evening and saturate it with a small amount of carbohydrates, then in the morning when training on an empty stomach, we will get the maximum benefit.

For dinner, you can use a group of vegetables that has no more than 3-6% carbohydrates.

This group includes:

Fruits should not be eaten in the evening, as they are high in carbohydrates and are considered an excellent energy resource. Limit fruit intake to 250 g per day and not in the evening.

It is very difficult to train on an empty stomach, since the body has not received its portion of energy in the form of various foods. I felt it myself and found a solution. When I wake up, I drink a glass of water, and 10 minutes later a small cup of hot, weak tea or coffee without sugar. This gives me the energy to dance for 60 minutes.

I hope that my article has convinced you that doing aerobics or any cardio exercise at an average pace and lasting for minutes on an empty stomach, that is, on an empty stomach, will bring you health and benefits. Before exercising on an empty stomach, if you have any diseases, be sure to consult your doctor.

Articles on related topics.

Pre-workout nutrition causes a lot of controversy among doctors and nutritionists. But new research shows that fasted exercise, especially fasted cardio, is much more beneficial than your standard morning workout after breakfast.

Benefits of training on an empty stomach

You can burn more fat

Immediately after waking up, glycogen reserves in the body are running low, there is little insulin in the blood, which affects the catabolic process (the process of breaking down fats). In other words, the higher the insulin level, the slower lipolysis, the breakdown of fat, occurs. This actually slows down the weight loss process. Significantly slows down. This is why many trainers advise their clients to train in the morning, immediately after waking up, before coffee and breakfast.

In the morning, glycogen levels are low, so the body uses energy from its own fat reserves during exercise, rather than from food received, and low insulin does not interfere with this process. However, due to the evolutionary process of self-preservation, lipolysis occurs more slowly in the morning.

In the morning, in addition to low insulin, every person should normally have high levels of growth hormone. Since we don't eat anything at night (on diet!!!), growth hormone is released as a response to hunger. This, in turn, increases the catabolic process. Insulin is the opposite of growth hormone, meaning the production of one hormone slows down the production of the other. Due to this, the benefits of training on an empty stomach in the morning are many times higher than from training on an empty stomach in the evening. This way you burn your fat reserves, and not the energy received during the day from food, so weight loss occurs many times faster (provided during the day).

Exercising on an empty stomach prevents stomach upset

Eating before a workout is a bad idea and will cause stomach upset in most cases. Eating too much or the wrong foods two hours before your activity period can slow down your workout pace. In addition, blood flows to the muscles, and the stomach works more slowly. Because of this, food is not digested, but ferments. At first, this can lead to excessive gas formation and bloating, and over time, to gastritis and a slowdown in metabolism. Never train with a full stomach. If you eat carbohydrates, make sure your workout is scheduled at least 2 hours after eating. If you eat proteins (especially red meat), then train 3 hours after eating.

Exercising on an empty stomach prevents overeating

It is recommended to drink a glass of warm water 15-20 minutes before training (immediately after waking up). After that, you can go to training. It will be easier to do exercises on an empty stomach, and water will kick-start your metabolism.

Bring a banana to the gym if you work out for more than 60 minutes in the morning. This will help satisfy your hunger 20-30 minutes after exercise and prevent you from overeating throughout the day.

How to exercise on an empty stomach for health benefits

You already know that there are two main types of physical activity - cardio and strength.

Strength training is needed to build muscle mass, and cardio is needed to speed up metabolism, increase endurance and burn fat, that is, lose weight.

If you exercise on an empty stomach, experts recommend choosing cardio exercise. Research shows that this type of exercise releases adrenaline into the blood, which triggers the breakdown of carbohydrates and fats for use as energy. In addition, the catabolic process is accelerated in the morning, that is, weight loss will occur faster.

It is not recommended to do strength exercises on an empty stomach, especially with heavy weights (with a barbell or dumbbells). This type of exercise requires strength, not just endurance, as in cardio. And people have little strength in the morning due to overnight fasting.

There is a lot of controversy about working out on an empty stomach. Many claim that they actually help you lose weight more effectively. Others say that without refreshment, productivity will be much lower. Where is the truth? Should you eat before training? Let's try to figure it out.

What happens in the body?

From the moment you wake up in the morning until your first meal, insulin levels in the blood are at their lowest point, and glycogen stores are completely depleted overnight. What does it mean? Low insulin levels ensure more active lipolysis - the breakdown of fat cells, and we lose weight faster. Yes, indeed, numerous studies confirm this fact. But not everything is so rosy: there are some nuances.

Why is training on an empty stomach harmful?

If you regularly exercise on an empty stomach in the morning and ignore the morning meal before that, a constant deficiency of insulin in the blood can even provoke a disruption in its normal and natural production. The result is problems with blood vessels, arterial disease, exacerbation of chronic diseases, stroke, and even the development of diabetes or hypoglycemia.

In addition, a complete refusal of nutrients before training will not give you the dose of energy that is necessary for full performance. You simply don’t have enough strength to do the exercises, your endurance will also be zero, you will feel weak, tired, and apathetic. And if you decide to push yourself and lift a lot of weight, this is fraught with muscle injuries (due to low sugar levels in muscle tissue).

Why is it necessary to have breakfast?

And if you think that working out after breakfast will not give you the desired effect for weight loss, then you are deeply mistaken. Despite the fact that fat reserves will be consumed faster on an empty stomach, this will still not give the desired and immediate result. It's all about not so much the calorie consumption per workout, but the total calorie consumption for the whole day - this is the key to competent and gradual weight loss.

American scientists conducted a study in which one group of people ate breakfast regularly, and the second skipped their morning meal. For the first “experimental” subjects, the total energy consumption per day was approximately 2800 kcal, and for the second, only 2000 kcal. And even when physical activity took place, the first group expended approximately 500 kcal during exercise, while the second only 300 kcal. An impressive difference, isn't it?

Drawing conclusions

Therefore, we can safely draw the conclusion that you need to have breakfast before training. Of course, your weight loss process will not be as fast as during long-term training on an empty stomach. But it will proceed competently, without harm to the body, and you will not provoke various disruptions in the functioning of systems and the development of diseases. In addition, your performance during training will increase significantly, which means that you will work more productively!

Speaking about the ability to perform physical exercises on an empty stomach, one thing can be said. Times change and what once seemed obligatory to us now turns out that this is not so. We used to be taught that we needed to eat six times a day. And consumption. I'm afraid that some of your beliefs will not stand after this article.

Recent research shows that our bodies benefit from intermittent fasting. And exercising while restricting food intake may not be as bad as we think. In fact, working out on an empty stomach helps our muscles, regulates insulin in the body and burns fat.

Is it better to exercise on an empty stomach?

If you want to hear the answer right away, it will be “Yes”

Does this mean all the talk about pre-workout nutrition was in vain? Not really.

Some studies have shown that consuming carbohydrates before exercise allows athletes to exercise longer than when training in a fasted state.

Another study found that men in a fasted state ran significantly shorter distances in 60 minutes. Compared to men who ate pre-workout. This was despite no significant differences in heart rate and perceived exertion.

But while not eating before a sporting event will not help you achieve outstanding results, training on an empty stomach for amateur sports can help in other ways. Especially for those who care more about their waistline than their marathon results.

Another of the many studies conducted on this topic concluded that men aged 18-25 who did fasted cardio exercise while eating a high-fat, high-calorie diet had improved glucose handling and insulin sensitivity compared to those who exercised without refusing food before exercise or those who did not exercise at all.

Of these three groups, only those who did the exercises on an empty stomach did not gain weight.

What happens to our body when training on an empty stomach?

Overall, the science when comparing fasted and non-fasted exercise shows that the results are not very convincing about the benefits of fasted exercise. But despite this, we know that intermittent eating triggers a different mechanism for the production of insulin in the body, as well as tissue growth hormone. It is also known that intermittent fasting can disrupt our traditional understanding of protein digestion.

Insulin

Insulin is a hormone that regulates the use of nutrients by the liver, body muscles and fat cells. Insulin is produced in response to carbohydrates entering the body. Every time you eat a banana, chew a carrot, swallow a sandwich or drink juice, your body produces insulin, which controls the absorption of nutrients.

Insulin thus helps control fat cells and food absorption. And lack of sleep, lack of mobility (or a sedentary lifestyle without physical exercise), overheating the body makes our bodies less sensitive to the effects of insulin. This so-called insulin resistance makes us more prone to diabetes, certain types of cancer and obesity, which is a major health problem in developed countries.

If you decide to exercise when most of the glucose and glycogen from your last meal has been used up, your body is likely to turn its attention to fat cells as an energy source. After fasting, your body becomes most sensitive to the insulin it produces whenever you eat. This sensitivity does magical things - it uses carbohydrates, proteins and fats more efficiently, promoting body muscle growth and fat burning.

One of the explanations why the topic of insulin resistance has become such a hot topic today is the theory of “thrifty” genes. She states that our metabolism speeds up when we consciously vary periods of eating and fasting, vigorous exercise and rest. This is in stark contrast to the lifestyle of the modern average person with his sedentary lifestyle, abundance of food and constant consumption of it. The thrifty gene theory is one explanation for why a 2005 study found that intermittent fasting improved insulin sensitivity and glucose uptake in healthy men.

A growth hormone

In fact, opinions about this hormone are mixed. It is present in the bodies of children and adolescents and is declared as an anti-aging factor for older people. But while its effectiveness against aging has not been confirmed, it directly affects the growth of muscle mass and increased muscle strength. Daily fasting can increase the production of growth hormone in the body by 1.5 times.

A few words about another hormone

Testosterone is one of the hormones that directly affects the increase in muscle mass and burning fat in the body. And it is precisely because of this that the answer to the question of whether it is possible to do strength exercises on an empty stomach can only be in the affirmative. With a short-term refusal of food, the effectiveness of strength exercises increases several times.

Protein

After these facts, you may be thinking, “even if exercising on an empty stomach is beneficial in the short term, does fasting affect protein digestion and muscle mass?” In fact, studies in young, middle-aged, and elderly adults have found that you can take your daily dose of protein at one time without harmful effects. To back this up, it's worth mentioning that there is some evidence that eating once or twice a day is more effective for building lean muscle mass.

In general, if you are not an athlete, then your strategy can be quite simple. If you don't want to eat, then don't eat.

Speaking about training on an empty stomach, we can say the following: skipping one or two meals before training will not harm your body. Intermittent fasting can reverse the effects of a sedentary, high-fat, high-calorie diet and make more efficient use of the food you eat. Working out in the morning on an empty stomach will help you better absorb the foods you eat after your workout.

The question of whether you should practice exercises on an empty stomach to lose body weight is not as clear-cut as it seems. Although it seems that everything is simpler than that: after skipping a meal, the body has nowhere to get energy and it begins to take it by burning fat.

For example, a study at the University of Bath in the UK found that when overweight people briskly walked for 60 minutes on an empty stomach, their bodies switched to increased burning of stored fat (not carbohydrates) compared to the group that ate before. training.

“Overweight people respond differently to fasted exercise—they typically increase their metabolic rate faster than healthy people,” says Darrin S. Willoughby, Ph.D., director of the Exercise and Biochemical Nutrition Laboratory at Baylor University in Texas. .

This is confirmed by the British Journal of Nutrition, reporting findings from a 2013 study. When exercising on an empty stomach, people lost 20% more fat than people who had a small snack before exercise.

Another experiment published in the International Journal of Sports Nutrition and Exercise Metabolism found the same result: Fasted aerobic exercise reduced body fat percentage more than pre-workout meals.

But some scientists do not agree with such conclusions.

Sports nutritionist Kelly Pritchett. “Why is excess fat burned?” - he reasons. "To perform intense physical actions such as long-distance running or weight lifting, your body must burn glycogen, or stored carbohydrates. If it used them, then there must be a power switch.

Presumably due to the excess fat that you have. But there's one catch. Your body is not a fan of exercise, and as you quickly burn fat, your body begins to regulate its metabolism and burn fewer calories. Your body goes into survival mode and uses more nutrients to store energy in the form of fat at your next meal.”

In this case, we can draw the following conclusion. Each theory has its supporters and opponents. But the theory of fasting training has enough followers who show its effectiveness. And if you're concerned about weight loss, the best way to find out if fasted exercise is right for you is to try it yourself and decide if it helps you or not. After all, people are individual and what does not suit one person can perfectly help another.

And if after all of the above, you ask me "is it possible to eat before training", I will answer "Yes." You can, but if you try fasted training, you can find out exactly what is best for you.

Experts and amateurs are always arguing about the effectiveness of sports, its new trends. And about what exercises to choose to burn fat. There is even debate about exactly how to combine diet and exercise to get the best results. Now there's a new dilemma in the sports world: Will exercising on an empty stomach help you lose weight faster?

Bodybuilders are one hundred percent confident in the veracity of this hypothesis. However, some athletes continue to use before exercise. I decided to look into this issue and considered several different opinions.

The theory of exercise on an empty stomach is based on the fact that exercising on an empty stomach helps you burn fat faster. In the morning the level in the body is significantly lower than at any other time of the day. Therefore, it is assumed that the body on an early run will draw energy from fat reserves.

• Fat burns faster. A study in 12 men found that fasted treadmill runners burned up to 20 percent more fat ( 1 ). Interestingly, people who skip breakfast do not tend to overeat during the day. Jogging or exercising will have a beneficial effect on your diet. As a result, you will achieve your ideal figure faster.
• Productivity increase. When carbohydrate levels are low, the results from standard workouts will be more effective. The body reacts more strongly to physical activity and calories burn out more easily.

• Time without food will help you lose weight. Training on an empty stomach is good because during it you will not eat food. And after class, refresh yourself with whatever you want. But there is one limitation: you should eat strictly at certain hours. The human body knows its nutritional schedule. Hormones are more active in burning fat and promoting weight loss during non-eating hours. Exercising before meals can encourage the body to burn even more fat, especially if you exercise in the morning.
• Improving the body's response to insulin. When we eat, the body uses insulin to collect all the nutrients from food. But when we eat too many carbohydrates and sugar, the body becomes less responsive to insulin. Vitamins and microelements are not fully absorbed. Over time, insulin builds up, which can cause a number of chronic diseases such as diabetes. Short fasts awaken insulin sensitivity. The hormone is not produced in excess, and the body remains receptive to it.
• Workout Inspiration. Very often people do not have enough time and energy for regular sports exercises. If you have to go to work early, it's better to get your workout in early and go, rather than wait for the food to settle down to exercise.

Who is not suitable for sports on an empty stomach?

International Journal Research sports nutrition They say that fat is lost better if you eat before training. The result of this experiment does not coincide at all with that described above. ( 2 ) Therefore, this approach to nutrition is not suitable for everyone.

Another problem is that it will be very difficult to perform various exercises on an empty stomach; you simply won’t have enough strength. A light pre-workout snack containing carbohydrates, protein and healthy fats can provide the energy you need.

Replenishing your energy reserves will help you more easily overcome intense exercise, which burns a large number of calories in the shortest possible time.

If you do endurance exercise, are used to running long distances, or have mastered triathlon. Working on an empty stomach at a grueling pace is simply unrealistic. After all, at the passing stage you will need a lot of strength.

And for people with diabetes or low blood sugar, “fasted” sports activities are even contraindicated. Be sure to have a snack before exercise, this will guarantee your safety during training.

conclusions

I wanted to tell you about the existence of the theory of exercising on an empty stomach. But remember that it may not be unconditionally suitable for everyone. Personally, I used to train on an empty stomach and it was always very difficult for me to go to training. Now I still prefer to recharge my energy an hour before training and I don’t regret this approach at all.

In any case, you should remember to drink water before and after training. Energy levels depend on the amount of fluid in the body.

And I advise you to pay special attention to what you eat after. A combination of protein and healthy carbohydrates will help your muscles recover. Eat eggs/meat and vegetables within the first 45 minutes after training and you will feel much better.

Monitor your health and the beauty of your figure. Choose the types of exercises that you enjoy.
