Intermittent fasting: scheme 16/8, 20/4, 14 and 18 hours, pros and cons, rules for women and men, diet results

Intermittent fasting, cyclical, periodic - these are all names of a nutritional scheme in which periods of complete refusal of food and its intake are clearly separated. There are several schemes: 16/8 - the most common, 14/10, 20/4 (the most difficult for beginners).

You can fast for 36 hours straight or follow the principle of 5 days eating and 2 days fasting. The results will not only be weight loss, but also an improvement in overall health: this strengthens the immune system, slows down the aging process, and improves performance.

The most popular 16/8 intermittent fasting scheme is recommended for 1 week, 1-2 times a month. Even after 7 days of the diet, you can see a weight loss of 2-5 kg.

What is intermittent fasting

Intermittent fasting
The essence of the intermittent fasting process is to replace a 16-hour period of controlled fasting with an 8-hour period of eating. Foods rich in protein, fiber and vitamins are allowed for consumption. The task is not difficult, since the fasting period includes 9 hours of sleep, so already 7 hours after waking up there will be an interval when it is allowed to eat food.

Periods:

Hunger strike - 16 hours - consumption of solid foods is prohibited, you can drink filtered clean water or drinks without calories: decoctions, green tea, coffee without additives. At this time, metabolism starts, fats are quickly broken down, and toxins are eliminated.
The eating window is 8 hours – the time for consuming the entire daily calorie intake with food in the conditions of fractional meals. During this period, the body receives the required minimum of nutrients.

It is recommended to adhere to this type of diet for no more than 10-14 days, otherwise the body may turn on the reverse function and minimize the consumption of adipose tissue. And every calorie acquired will be immediately stored in fat depots.

What is short-term fasting?

Intermittent fasting is an eating regimen in which periods of eating alternate with periods of fasting.

The most popular is the 16/8 scheme, which suggests that you need to fast for 16 hours every day, and use an 8-hour interval to eat.

Intermittent eating has proven benefits for the body. It allows you to prolong life by reducing the incidence of malignant neoplasms, diseases of the cardiovascular, digestive, endocrine and central nervous systems.

However, the most popular use of intermittent fasting is for weight loss.

Intermittent fasting is alternating periods of fasting and eating. The technique has many benefits for human health.

Benefits or harms of weight loss techniques

Intermittent fasting 16/8 for women, reviews of which are mostly positive, has advantages and disadvantages in use, proven by clinical studies at the Japanese Institute of Dietetics.

Benefits of fasting:

Acceleration of hormone production due to activation of intercellular processes. The body stops eating for a while, because of this, insulin in the blood drops, fat “burns” and growth hormones are produced, which stimulate muscle building and cellular regeneration.
Fat burning occurs due to the body’s consumption of previously stored fats when the diet is reduced. Weight loss occurs due to a calorie deficit, and a person uses up lipid reserves to function.
Acceleration of metabolism by 4-14%. The most noticeable process of weight loss is observed in the waist and abdomen, as the most common fat depots in women.
Muscle mass is maintained as growth hormone is produced. This fact determines the popularity of the method among athletes.
Stress resistance to external factors increases. Ease of movement, sound sleep and good health.
Intermittent fasting (IF) reduces the risk of type 2 diabetes by reducing blood insulin levels.
Activation of thinking processes, increased performance and energy boost.
Normalization of blood pressure, digestion processes and fat breakdown.
Strengthening nails and hair, rejuvenating the skin, treating acne and cleansing organic systems.
No financial costs and stable results from the principles of “hungry” nutrition.

Answers to frequently asked questions

This section discusses the most controversial situations and questions regarding the 16/8 regime:

Is the 16/8 protocol suitable for women? As already mentioned, the female body is more sensitive to limited nutrient intake. It is recommended to change the standard pattern (for example, fast for 12-14 instead of 16 hours). You should also adhere to the method not on an ongoing basis, but periodically: several times a week (for example, Monday, Wednesday, Friday) or every other day.
How long can you eat according to this system and how often? If the diet is well tolerated by the body, there are no restrictions regarding the duration of fasting. If adverse reactions develop, you should seek the support of a doctor.
Is it possible to follow the regime during pregnancy? Such fasting negatively affects the state of a woman’s reproductive system, which can lead to an unfavorable pregnancy outcome. In addition, the health of the fetus is negatively affected by the unsystematic intake of nutrients into the mother’s body that are essential for adequate growth and development. Conclusion: the technique is prohibited during pregnancy.

Possible harm

Intermittent fasting can cause side effects that cannot be ignored, as they can cause serious complications for the body.

For example:

Constipation or any other digestive disorder can be relieved by taking laxatives.
Dizziness and headaches occur due to stress in the diet. After 2 weeks the syndrome disappears.
Stomach discomfort, heartburn, belching. Relieved by mineral water.
Spasms in muscle tissue are relieved by increasing protein intake.
Shift or disruption of the menstrual cycle.

In order for fasting to be therapeutic and not harmful, it is necessary to consult a physician, closely monitor your health and correctly enter and exit fasting.

Important Tips

Below are a number of tips that will help maximize the positive effects of fasting - losing more extra pounds:

Defining personal goals. In most cases, a person who switches to such fasting has a specific goal - reducing body weight in an aesthetic sense or improving health, etc. The final goal must be present, since it is this that will allow you to bring what you started to the last stage. The absence of psychological attitudes is the key to failure in the diet. There are no results without true faith in them.
Determination of energy needs. The intermittent fasting technique does not prohibit the amount of food consumed during periods of non-hunger. This means that body weight can begin to gain if the calorie content of food consumed significantly exceeds the physiological norm. It is recommended to ration food consumption and maintain caloric intake.
Drawing up an individual nutrition plan. If you are interested in losing weight, it is recommended that you plan what you will eat in the next few days. This will make it possible to more accurately keep track of the calorie content of the daily diet, as well as its qualitative composition, which will prevent the development of a deficiency of vitamins, macro- and microelements.
Health monitoring. Regardless of the intermediate results of fasting, you should be attentive to your health and promptly register any deviations. Changes in the emotional background, blood pressure, interruptions in the heart or palpitations in the chest, constipation, abdominal pain and any other pathological manifestations uncharacteristic for humans are a reason to abandon the technique and seek help from specialists.

Following short-term fasting techniques is a complex process that requires extensive preparation and careful monitoring.

Types of Intermittent Fasting

Intermittent fasting 16/8 for women (reviews demonstrate the experience and results of the procedure) comes in several types.

Types of therapeutic fasting:

Classic. The time to refuse food is 16 hours, and the remaining 8 hours are the food window, which lasts from 13.00 to 20.00 without a standard breakfast. This type is difficult to comply with; it is better to move the window frames and customize the menu to suit you.
Moderate. 14 hours “hungry” and 10 hours for food. The scheme is considered the most gentle, suitable for beginners. It is important not to violate the menu and avoid breakdowns.
Daily regime. 24 hours of fasting between meals. The system is complex due to the long period of fasting.

It is better to start with a gentle regimen, gradually moving to more complex regimens if the body is accustomed to the previous regimen.

Alternative Interval Diet

The 16/8 scheme is not the only one; there are also alternative options for intermittent dieting, which makes it possible to individually select a nutrition/fasting schedule. For example, the frequency of 12/12 is considered quite popular. The period of hunger strike also includes the usual night sleep, due to which the body easily tolerates temporary deprivation.

Don't eat 14 hours a day

Not eating 14 hours a day means that the “eating window” is 10 hours, and this is convenient for beginners and men who are engaged in physical labor or regularly carry out strenuous training. This option suits absolutely everyone, meal schedule:

breakfast – 8 am;
second breakfast – 11 am;
lunch – 14-00;
afternoon tea – 16-00;
dinner – 18-00.

Intermittent fasting 20/4: scheme

The 20/4 intermittent fasting scheme is called the “warrior diet” and is suitable only for those who have been practicing the technique for a long time and whose body calmly reacts to the complete exclusion of food. It is understood that the “eating window” is open only 4 hours a day, and during this period it is recommended to have 2 full meals - for example, at 8-00 and 12-00 or 14-00 and 18-00.

This diet plan can be used no more than 2 times a week.

“Eat/don’t eat”, or daily fasting

Everything is simple here: the period of complete refusal of food is 24 hours - after breakfast at 8-00, the next meal can only be taken the next day at the same time. Such unloading for the body can be done 1-2 times a week.

Post 36

A 36-hour fast is considered the most effective method for losing weight, but it is difficult to maintain. You can follow two options for the scheme:

breakfast at 8-00, then fast until dinner the next day at 20-00;
dinner at 19-00 and fasting until the second day (breakfast at 7-00).

You can follow this scheme no more than once a week.

5:2

The author and developer of the fasting scheme, Dr. Michael Mosley, suggests eating properly and nutritiously 5 days a week, and completely fasting for 2 days. But he allows concessions during periods of fasting: you can eat 500 calories worth of “light” foods per day, dividing them into several meals or eating them at once.

This scheme was used for a long time on an experimental group of human volunteers at the University of Florida. 24 people participated in the study. After just 70 days, there was steady weight loss, strengthening of the immune system, slowing down aging, accelerating regenerative processes and reducing cholesterol and blood sugar levels.

Contraindications

Not everyone can use the method of intermittent fasting for the purpose of healing and losing weight due to the existence of a number of medical contraindications.

You cannot follow an interval diet if you have the following health problems:

open and closed tuberculosis;
diabetes mellitus type 1 and 2;
oncology in any degree;
chronic diseases of the cardiovascular system;
hypotension and hypertension;
body mass index less than 15;
kidney dysfunction;
pregnancy in any trimester;
breast-feeding;
unstable central nervous system;
peptic ulcer;
age up to 18 years.

All of these contraindications are permanent, and the recommendations cannot be ignored, since a sudden change in diet has a negative impact on the biological rhythms of the body.

Indications and contraindications

The scientific and medical literature contains hundreds of examples of the healing power of fasting. It often turns out to be a very effective remedy in the event of acute diseases. Loss of appetite in this state is the body’s main signal that it should not be distracted by digestion, because. he wants to direct all his strength to fight the sudden illness. It would be wise to skip 1-2, or even several meals.

In case of chronic diseases, fasting can also be useful, because... it helps the body mount a sudden, dramatic response to a chronic condition, which can turn the tide of the disease. In any disease state, fasting helps cleanse the body of toxins, dead cells, and promotes tissue regeneration.

Nutritionists consider the following to be the main medical indications for fasting:

cardiovascular diseases (atherosclerosis, stage I-II hypertension, coronary disease, arrhythmia)
Gastrointestinal diseases (dysbacteriosis, chronic gastritis, cholecystitis and chronic pancreatitis, heartburn, flatulence, liver and pancreas diseases)
allergic diseases (urticaria, food and drug allergies)
skin diseases (herpes, neurodermatitis, psoriasis, seborrhea, scabies, dandruff)
problems with the musculoskeletal system (arthritis, arthrosis, rheumatism)
diseases of the genitourinary system (cystitis, adenoma, prostatitis, inflammation of the uterus)
respiratory diseases (tonsillitis, laryngitis, pharyngitis, bronchial asthma)
CNS disorders (neuroses, depression, continuous flaccid schizophrenia, sleep disorders)
obesity and other weight problems
resistance to certain types of drugs

However, there are people for whom intermittent fasting is not safe, and for some it is generally contraindicated. Absolute contraindications include:

reduced body weight (over 15% of normal)
oncological diseases, especially with immobilization of the patient
acute appendicitis
active tuberculosis of the lungs and other organs
systemic diseases of the blood and veins (thrombophlebitis, phlebopathy, etc.)
second half of pregnancy and breastfeeding
type 1 diabetes mellitus
cardiac arrhythmias
chronic hepatitis and cirrhosis of the liver
chronic renal failure
postoperative conditions

In addition, there are relative contraindications. If you have these diseases, the risk of complications or exacerbation of existing ailments is too great compared to the possible positive effect of fasting:

ischemia
low blood pressure
inflammatory diseases of the kidneys and urinary tract
stomach and duodenal ulcer
anorexia nervosa
diabetes mellitus type II
childhood or old age
taking certain medications

The list of restrictions can be expanded depending on the type of diet, its duration, health status and individual living conditions (for example, climate). Sometimes diseases from one group move to another - from relative to absolute, and vice versa. It happens that a contraindication may even become a reason for fasting treatment. In any case, you need to approach the issue of fasting wisely, carefully, gradually, and in difficult cases you cannot do without consulting a specialist.

List of possible side effects of fasting

constipation This is normal - the less that goes in, the less that comes out. It is necessary to increase the consumption of fruits and vegetables. You should resort to medical remedies only in case of obvious discomfort. Regular laxatives will do.
headache. They often occur in the initial stages of fasting and gradually disappear on their own. It is believed that their cause is a decrease in salt entering the body, so it is possible to additionally take it in broths or mineral water for some time.
rumbling in the stomach. The problem is solved by drinking mineral water.
heartburn. We must try not to transmit it during the eating window. Maintain an upright position longer after eating. At night, you can raise the head of the bed slightly.
dizziness. Usually caused by dehydration. It is necessary to increase the amount of fluid consumed. The cause may also be lack of salt and low blood pressure.
muscle cramps. It is necessary to take magnesium supplements or magnesium baths.
refeeding syndrome. It occurs extremely rarely, usually after a long (1-2 months) fasting. The reason, as a rule, is an incorrect (too abrupt) exit from the diet. A sudden influx of carbohydrates and fluid can cause potassium, magnesium and phosphorus to move inside cells. This leads to disturbances in the functioning of the heart, respiratory system, electrolyte imbalance, and sometimes even death.

You can rely on the presented plan:

8.00 – glass of clean water, 1 tsp. simple amino acids for athletes;
9.00 – a glass of black or brewed green tea;
11.00 – tea or coffee;

You can change the intervals, adjust them to suit yourself, observing the time frame and principles of the hunger strike.

Sports while fasting

For athletes, training should be scheduled 2 hours before the start of the eating window and exercise should be performed on an empty stomach. During active exercise, 1 tbsp is allowed. l. BCAA amino acids for active muscle building. It is important that the building will not happen every minute, since the process of building muscles is a long process.

For women involved in dancing or yoga, amino acids are replaced with protein shakes, which are drunk after classes as part of the nutritional period. The workout combines cardio and strength exercises so that the muscle fibers do not break down.

It is better to include the following exercises:

Running on rough terrain or on a track – 15 min.
Exercise bike or riding in nature – 20 min.

How to get out of fasting?

16/8 intermittent fasting for women and men requires the right outlet. Reviews from those losing weight indicate the inadmissibility of ignoring the correct way out of their hunger strike, since overeating during this period can threaten poisoning and indigestion.

Universal recommendations:

Reduced food portions. Divide the normal amount of food into 3 parts, and then in half. For convenience, use a small serving saucer and a teaspoon. It is better to follow generally accepted nutritional standards: ½ plate - vegetables, ¼ - protein, ¼ - complex carbohydrates in the form of cereals.
Inadmissibility of overeating due to overload in the gastrointestinal tract and the threat of indigestion. You should completely refuse food in the evening, only allow vegetables or kefir.
Delaying the introduction of previously unacceptable products. Fast food, carbonated sweet drinks and baked goods should be completely abandoned, exporting the habit from fasting to healthy habits forever.
A gradual increase in daily caloric intake to the normal amount of 3000 kcal. It is better to make a menu from healthier products.
The food in the dishes should be subjected to maximum thermal and mechanical processing, so that it is easier to absorb and digest for a sleeping stomach.
Continuation of physical activity as prevention and improvement of the body.

Following simple and clear recommendations will help prevent discomfort in the stomach and side effects during the transition to a normal diet.

Side effects

Diet may cause side effects. A weight loss program like this can be a real challenge. Therefore, the production of the hormone cortisol is activated.

List of side effects:

Disturbance of the gastrointestinal tract, manifested in the form of constipation. Due to the decrease in the volume of food eaten, the number of bowel movements decreases. If there is no discomfort, there is no need to worry. If discomfort occurs, you can use mild laxatives.
In the first stages, headaches occur. You can get rid of them by adding a little salt to your food.
Stomach problems can be solved with still mineral water.
Muscle spasms.
Refeeding syndrome.

The role of nutrition that a person receives during the “food window” is very important. The diet should be balanced. Due to an unbalanced diet, weight may decrease slowly or the above side effects may begin to develop. Intestinal motility is impaired, and constipation develops due to lack of fiber. With a small amount of protein, muscular dystrophy and slow metabolism develop. Loss of muscle mass can be reversed through exercise.

Results and effectiveness of the weight loss technique

The effect of intermittent fasting is sustainable and 100%. The amount of fat lost directly depends on compliance with the rules of weight loss and the personal characteristics of the body.

After how many hours of fasting does the weight loss process begin?

The process of losing weight starts after boosting your metabolism. When eating food, insulin, which is produced by the pancreas, increases in the blood, and metabolism slows down. During fasting, processes are aimed at regenerating and restoring the health of the body.

A calorie deficit significantly reduces sugar and insulin levels, and the concentration of growth hormones increases. There is a feeling of hunger.

At this time, catecholamines are sent to fat cells and starts the process of melting the subcutaneous lipid layer in problem areas. The process will start after 1-2 days of fasting and will amount to up to 2 kg per day, but you cannot count on rapid weight loss, since the rate of weight loss will soon decrease.

What results can be achieved in 1-2 weeks?

The greatest effect from a hunger strike can be achieved after a week of abstinence, which is best done monthly for preventive purposes. When you reach the desired weight, fasting days are practiced once a week, since even one-time fasting cleanses the intestines, helps control appetite and has a positive effect on well-being.

Over a period of 2 weeks, according to reviews of those losing weight, you can lose from 2 to 5 kg.

How to maintain your weight loss results?

The results of intermittent fasting when done correctly are sustainable.

Compliance with the following rules allows you to help consolidate the effect:

Including large volumes of clean or melted drinking water in the menu. Hydration promotes a feeling of fullness and appetite control.
Sleep at least 8 hours a day, since during the rest period the body rests, the muscles relax, and the metabolism remains running.
A positive attitude towards both fasting and food in general. This promotes a lack of stress and a good mood.
A busy life distracts you from thoughts about food. An active lifestyle also contributes to weight loss due to physical activity.
Particular assistance is provided by anti-cellulite or therapeutic massages, which activate blood flow and stimulate metabolic processes.
Active cardio training and strength exercises in combination with a properly balanced diet allow you to achieve maximum results and maintain your weight loss results. For prevention, 2-3 workouts per week and daily exercise are enough.

Interval fasting 16/8 for women will lead to effective reduction of fat layers in problem areas.

The effect is facilitated not only by the acceleration of metabolic processes, a decrease in insulin levels and an increase in the amount of growth hormones. Physiological changes are aimed at facilitating the fat burning process. Numerous positive reviews and benefits of intermittent fasting indicate improved digestion, faster metabolism and healthier body.

How it helps you lose weight - 5 facts

Intermittent fasting is effective for weight loss through several mechanisms. For example, according to foreign experts, the technique allows you to lose from 3 to 8% of weight even in a short period of time (from 3 weeks). The main mechanisms of influence on the metabolism of adipose tissue are discussed below.

Acceleration of metabolism

Scientists from the UK found that during fasting, metabolism accelerates by about 3.6%.

As a result, there is a faster breakdown of lipids in fat depots (mainly abdominal fat) in order to obtain energy to meet the body's needs.

Increased breakdown of fat cells also compensates for the loss of body temperature observed during prolonged fasting.

During fasting, general metabolism accelerates, “forcing” fat cells to be destroyed in order to obtain energy.

Decreased insulin production

Insulin is a hormone that promotes the absorption of glucose by all cells of the human body.

When the intake of food into the body stops, there is less glucose in the blood, therefore, according to foreign experts, insulin ceases to be produced. In response to this, all cells of the body secrete glucose back into the blood to correct energy starvation.

If such “glucose journeys” are repeated systematically, then body weight begins to decrease. The effect is also due to the loss of important properties of insulin, which cannot be realized due to its low content in the blood plasma:

ensuring the synthesis of fatty acids in the liver;
blocking the breakdown of adipose tissue.

A decrease in food intake into the body leads to suppression of the secretion of insulin, the main “fat-accumulating” hormonal substance.

Changes in hormonal levels

A sharp change in eating behavior affects the state of the whole organism, in particular, the level of release of a large number of hormones changes.

Australian experiments demonstrate that during fasting there is an increase in norepinephrine production by 2-10 times.

Such changes lead to a sharp decrease in blood glucose levels and the beginning of changes in metabolic activity. The path of “receiving energy” switches to adipose tissue, which begins to be intensively destroyed.

The release of somatotropic hormone (GH) also increases (at least 5 times). It promotes additional preservation of muscle mass and activation of adipocyte destruction.

During fasting, the human body undergoes significant hormonal changes. Changes in the secretion of biologically active substances enhance the fat-burning effect.

Suppression of hunger

When the intake of food into the body is limited, a strong feeling of hunger develops, which tends exclusively to increase. As a result, you want to eat more and more food. This desire is the leading reason why people refuse intermittent fasting.

Fortunately, already after 2-3 days the feeling of hunger begins to dull. This is due to the systematic migration of glucose into the cell and back, as well as improved trophism and microcirculation at the level of the brain.

On days 7-10, a person begins to endure periods of hunger with virtually no discomfort.

The feeling of hunger, which develops immediately after refusing to eat, begins to gradually dull from 2-3 days and practically disappears after a week and a half.

Preservation of muscle tissue

One of the most unpleasant side effects of many modern diets is that weight loss occurs not only due to fat deposits, but also muscle tissue.

American scientists claim that intermittent fasting has many advantages compared to diets. With it, the least loss of muscle mass is observed. Positive properties are observed only with a short period of fasting (up to 24 hours).

Of particular note is a study conducted in 2007. Eliminating just 1 meal a day (using a large lunch as an example) allows you to lose overall body weight, while even slightly increasing muscle mass.

Intermittent fasting burns fat but preserves muscle mass, which is extremely important for those involved in sports activities.

Other useful properties

Intermittent fasting has many other benefits for the human body:

Reducing cancer incidence.
Correction of dyslipidemia. As a result, the development of atherosclerosis is prevented (by reducing total cholesterol, TAG, LDL and VLDL) and abnormalities associated with this condition (coronary heart disease, myocardial infarction, CCI, stroke, etc.).
Prevention of type II diabetes mellitus and other carbohydrate metabolism disorders.
Reduced blood pressure.
Prevention of degenerative diseases of the brain (Pick's disease, Alzheimer's disease, Parkinson's disease).
General increase in life expectancy.

Fasting and training

Combining several diets with a system of intermittent fasting is common among athletes and those who want to lose weight quickly, that is, among people who want to get tangible results in the shortest possible time and are trying to combine several effective methods into one, the most effective one.

Bodybuilders, CrossFitters and other athletes have to balance intermittent fasting with their training schedule.

There are strict recommendations for them:

It is better to train at the end of the fasting phase;
exercising on an empty stomach (only if your health allows) will promote active fat burning;
If you need a boost, drink a pre-workout shake or eat something, but the portion should not be more than 25% of the daily value.

Intermittent fasting: contraindications

As with any food system, there are pros and cons. When you should not adhere to this nutritional method:

if you have any immune diseases
if the liver and kidneys are impaired, it is not recommended to follow the principles of IG
Complaints of stomach pain during fasting are very often observed, which is associated precisely with the presence of diseases that are incompatible with this food system. It must be remembered that the presence of various diseases of the gastrointestinal tract is a powerful argument not to adhere to such a plan. This is especially true for diseases such as gastritis.
while leading a very active lifestyle.
under severe stress, as well as if you have neurosis or insomnia.
You should also not start intermittent fasting if you are sick or simply not feeling well. You can practice this technique only if you are healthy and do not complain about your health.
Separately, pregnant and lactating women should be noted; this nutritional system is not suitable for them.

In any case, before making such an important decision, you should definitely consult your doctor to eliminate any possible risks.

Question answer:

Which is better - intermittent fasting or intuitive eating ? Comparing these two methods will not be entirely correct, because the IG has clear rules that must be followed, while the individual entrepreneur leaves the right of choice to the person.
Fractional meals or intermittent fasting Here everything is very individual, but it should be said right away that IG is not suitable for people who need to eat frequently and in small portions. Typically, fractional nutrition is practiced in the presence of various gastrointestinal diseases.
Is it possible to drink coffee during intermittent fasting Yes, on this nutrition system it is not only possible, but also necessary to drink coffee to suppress the feeling of hunger. The only point is that it must be an unsweetened drink.
How much weight can you lose with intermittent fasting ? As a rule, with large volumes, weight comes off faster, and very often overweight people lose up to 7-10 kg in the first month of such a system. At the same time, everything here is individual.
Intermittent fasting and training You can train during IF, the main thing is to properly balance your diet on these days. Be sure to have protein and slow carbohydrates on such days. It is also very important to choose the right time for classes. Here you focus on your feelings and well-being.
Intermittent fasting in bodybuilding This method is actually practiced in bodybuilding, especially during the cutting period. On such days, it is best to train on an empty stomach to burn the maximum number of calories. In addition, it is better to consume the maximum amount of calories after training.
Intermittent fasting while gaining weight Surprisingly, this method is also practiced when gaining weight - alternating high-calorie days and low-calorie days. This method is much more convenient than counting calories.
Constipation during intermittent fasting This phenomenon can indeed occur, but not only during IF. This is usually a consequence of low fiber intake. You should definitely include fresh vegetables and fruits in your diet to avoid such problems.

As you can see, IG is an excellent technique that really works! You will not only be able to lose weight, but also improve your well-being and get rid of bad habits. The main thing in this matter is the right approach and compliance with all the rules. And, of course, do not forget to consult your doctor!

Advantages and disadvantages of the method

Experts and bodybuilders have created several dozen intermittent fasting schemes. Some of them have undergone scientific tests in which people of different weights took part. During the research, it was confirmed that this type of hunger strike has a number of advantages, but disadvantages of the scheme were also discovered. The benefits of intermittent fasting are expressed in the following positive processes in the body:

blood pressure is normalized;
blood sugar and cholesterol levels decrease;
the risk of developing malignant tumors is reduced;
the body is cleansed of harmful substances and parasites;
metabolism accelerates;
weight loss;
inflammation decreases;
the functions of the gastrointestinal tract are restored;
phagocytes (cells of the immune system) are activated;
the ability to control appetite is developed;
immunity is strengthened;
the achieved result is more lasting than with other weight loss systems.

The advantage is that there is no need to limit yourself in food.
With PG, you don’t have to change your eating preferences. The main thing is that the portions do not exceed the volume of a couple of fists, and the number of calories corresponds to the daily norm. Among the disadvantages of this system are:

the presence of a long list of contraindications;
difficulty gaining muscle mass;
increased risk of stone formation in the bladder and gallbladder;
the existence of the possibility of influencing the psychological state;
the presence of side effects such as dizziness, irritability, clouding of consciousness, difficulty concentrating, nausea, headache, general weakness.

Before you decide to lose weight and dry your body, you should study the scheme in detail, paying attention to the possibility of causing more harm to the body than excess weight does. This applies to people with chronic diseases of the cardiovascular system and kidneys.

Indicative menu and products for intermittent fasting

This scheme is not a diet, and the daily menu can be familiar. You can eat all the foods that were included in your diet before fasting. It is worth paying attention to nutrition on training days. With increased load, it is necessary to replenish the body with carbohydrates and fats to a greater extent than with proteins. On rest days, you need to eat more protein-rich foods.

On training days, your diet should include:

Fats:

sour cream, cottage cheese, kefir, cream;
butter;
cheeses;
halva;
chicken;
goose, duck;
pork;
chocolate;
fatty fish (herring, sturgeon, salmon, saury);
mutton.

Carbohydrates:

confectionery products (sweets, cookies, marmalade, baked goods);
honey;
dates, figs, bananas, apricots, pears, strawberries, apples, gooseberries;
pasta;
cereals;
potato;
legumes;
beet.

On rest days, you should give preference to foods containing proteins:

cheese, low-fat cottage cheese, milk, sour cream;
poultry meat;
fish;
buckwheat, semolina, oatmeal, millet, rice, pearl barley;
bread;
peas, beans, soybeans;
pasta;
cauliflower, spinach;
nuts;
potato;
fruits, berries;
mushrooms.

Nobel Prize and fasting

Most people already know the fact that quite recently in 2016, Japanese scientist Yoshinori Ohsumi discovered the phenomenon of autophagy in yeast (scientists have known about the phenomenon since the 60s). His discovery has a rather indirect connection with the now popular fasting, including intermittent fasting. But among scientists there is an opinion that autophagy can have a positive effect on the human body. For example, it is believed that autophagy may be targeted to reduce the occurrence of cancer cells, so it can be assumed that this process may be effective in the fight against cancer cells.

Can we cure cancer? Perhaps Parkinson's disease too, because, as it turns out, autophagy can rid the body of mitochondria that cause this disease. Many scientists are now studying autophagy as an ability to prevent aging and the possibility of producing drugs that stimulate autophagy. Tests have not yet been conducted in the laboratory on humans, and there is a need to collect the necessary amount of data and statistics to officially declare the benefits of autophagy for the human body. This will require a huge amount of research. At the moment, scientists are just beginning to study how autophagy works in the cells of the human body.

The benefits and harms of diet

The system of intermittent fasting has many undeniable advantages. Some of them are even confirmed by scientific research.

However, you should only practice intermittent fasting, especially if you have health problems, after consulting with your doctor. Otherwise, there is a risk of developing problems with the gastrointestinal tract and other organs.

Positive sides

Intermittent fasting teaches self-control. Over time, a person learns to distinguish true hunger from the psychological need to chew something.
The slow rate of fat burning is compensated by a guarantee of lasting results.
The benefit of periodic fasting is that recovery processes are activated. The body replaces damaged cells with new, healthy ones, removes old ones or uses them to release energy.
Scientists from Southern California published an article in 2014 claiming that cells in the defense system regenerate better during periods of fasting. The body tries to save energy and recycles damaged immune system cells. During fasting, the number of old white blood cells decreases, but after eating food, new ones are produced and the number returns to normal.
