What is the keto diet: benefits and harms for those who like to eat fat

Almost all men and women dream of being the owner of a beautiful, fit, slim body.Fashion trends dictate their laws, offering hundreds of methods to lose weight and dry the body.Often, these miracle drugs and ways to lose extra weight turn out to be fake, not worth paying attention to.However, there are many effective options, one of which is the keto diet for weight loss, tested by many from their own experience.

What is the keto diet: the history and essence of the low-carb nutritional system

In pursuit of slimness, we are sometimes ready to take the most radical measures, reducing our body, leading to anorexia, which is very dangerous to health.Others exhaust themselves with strength training, but still can't achieve a toned body.This is because it is better to act comprehensively, combining proper nutrition and moderate physical activity.One of the progressive nutrition systems is the ketogenic system, which will be discussed in our article.

The keto diet (also called ketogenic or ketone) is a low-carb diet.At the same time, the diet is dominated by fat, as well as a moderate amount of protein.

Brief history

In the early twenties of the 20th century, doctors faced a serious problem - the treatment of epileptic seizures turned out to be ineffective.Against the background of their normal lifestyle, attacks occur regularly in patients.Then nutritionists develop a completely new nutritional system that helps relieve symptoms, minimize crises.Over time, it becomes clear that along with seizures, excess subcutaneous fat begins to melt.

Ten to fifteen years later, anticonvulsant drugs were introduced to help epileptics control their seizures.But a cardiologist from the United States, Robert Atkins, created a diet to lose weight, based on previous developments.True, the version contains carbohydrates and does not compromise on protein, which prevents the body from remaining in a state of ketosis, on which the entire harmonious system of the modern keto diet is based.

In the late nineties, American director Jim Abrahams decided to share the story of his son's struggle with epilepsy.Due to intolerance to certain medications, as well as "side effects" from them, the boy could not take the prescribed medication.The ketogenic diet helped him find a way out, for which Jim made a famous film called "Do No Harm" with Meryl Streep in the title role.This is how the keto diet went beyond a purely medical phenomenon and became common knowledge.

The essence of the keto diet: the state of ketosis

Where does the wild popularity of such a power system come from, and why does it really work?Normally, our body gets energy "fuel" from carbohydrates, converting them to glucose.It also nourishes brain neurons.However, when this product is lacking, the body begins to look for alternative nutrition methods using fat cells.

Research has shown that the ketogenic diet suppresses the body's production of the hormone ghrelin.He is responsible for hunger.With the right diet of this type of nutrition, you will stop suffering from the constant desire to eat something.This is a pleasant side effect of ketosis.

When our body stops accepting carbohydrates as its only source of energy, it turns to the same fat reserves that have been stored for a rainy day.They are processed by the liver, broken down into glycerol and fatty acids.They then form ketone bodies, which nourish the body and brain.

This process is called metabolic ketosis.It happens about the seventh day of the diet.Then the body stops the process of processing glucose (glycolysis), using reserves from the muscles, liver and other tissues, while at the same time activating lipolysis - the breakdown of high-quality fat.

The peculiarity of this type of diet is that you can lose weight by burning your own fat reserves.After all, there are no added carbs.In this case, the protein tissue remains intact.That is, such a diet is very suitable for losing weight and for those who are involved in sports that require special endurance (heavyweight, marathon, triathlon).

Type of keto diet

The key feature of the ketogenic diet is that it is a varied diet, depending on your body's capabilities.There are three main types of diets.

1. Standard.This is the most accessible type of diet, when carbohydrates are gradually reduced to an incredible minimum.It's perfect for anyone involved in sports or fitness.The main principle here is the rejection of the so-called refeed (days in which carbohydrate consumption is acceptable).It is very effective and provides a constant amount of calories.
2. Targeted or targeted.In this type, "loading" days are acceptable, when eating carbohydrate-rich foods is acceptable.For example, to get rid of drowsiness or fatigue during periods of intense training, for example, before a competition.
3. Cycle.This option is considered the most advanced, and is not available to everyone.With such a diet, you need to independently determine when it is time to replenish the supply of carbohydrates, which are needed, for example, during intense training or body fatigue.This implies a return to ketosis when balance is restored.

Nutritionists recommend starting with a standard diet, but if you feel unwell, switch to a gentler regimen.

Stages of body adaptation: pros and cons

Due to differences in genetic makeup, everyone has a different journey to ketosis.Some can do it in three or four days and not leave it for a month without any problems, while others can't achieve results even after a week.No need to worry and go to extremes, giving up in the middle of the process.The main thing is to understand what is happening in the body, where to start the keto diet and how to deal with negativity.

What happens to the body: the main phase and the keto flu

To get your body used to ketosis, it has to go through a difficult path with many changes.

Phase One: Glycogen Depletion

The first stage occurs between the sixth and twenty-fourth hour from the start of the ketogenic diet.The body is still actively consuming glucose, which was left in abundance from the previous meal.Due to the lack of injected carbohydrates, insulin levels decrease, which is why there is excessive urination.This is because sodium and water are thrown away as unnecessary weights.Some suffer from moderate dehydration, with all its "charms", such as dizziness, fatigue and irritability.

Second phase: gluconeogenesis

When carbohydrate reserves are depleted, the body enters the second phase, which can last anywhere from two to ten to fourteen days on the keto diet.The period of gluconeogenesis begins, when the liver, and sometimes the kidneys, begin to use non-saccharide compounds (amino acids, glycerol, lactate) as fuel.When glycogen is low, muscles become the primary source of energy.

During the second phase, the body loses so much sodium and water that many begin to experience strange flu-like symptoms.You may have an unreasonable headache, fatigue, and you just want to lie down and do nothing.Dizziness, joint pain, nausea, and weakness often occur.Don't worry, these symptoms have nothing to do with a viral illness or a cold.Below are suggestions on how to more easily put yourself into the metabolic state of ketosis.

Phase Three: Ketosis in person

This period may occur on the third to fourteenth day from the beginning of the ketogenic system.In most cases, it is achieved no later than the tenth day, but it all depends on lifestyle and genetic characteristics.

Indications for use and benefits

There are a large number of advantages from using such a power system.Everyone will find their own strengths.Medical indications for switching to a keto diet also vary.It is necessary to think about these things in more detail.

• The body uses its own subcutaneous fat as a source of energy, as well as deposits on internal organs.Therefore, a very fast weight loss effect is observed.
• Due to the type of low-carb foods you eat, the body itself will lower your blood sugar levels.This represents a good prevention of diabetes and is also used in its treatment.
• Ketones produced by the liver become good food for the brain.Some people turn to the keto diet to improve their mental abilities, improve concentration, and improve mental focus.According to recent studies, fatty foods taken also have a good effect on brain function.
• The link between being overweight and high blood pressure is undeniable.Therefore, by losing excess fat, you can normalize it at the same time.
• In a state of ketosis, hunger is significantly reduced, and fatty foods fill you up better, for longer.
• The condition of the skin improves significantly due to a decrease in the level of subcutaneous sebum.This has a good effect on getting rid of pimples and acne.

Much has been said and written about the benefits of this nutritional system for people with epilepsy.Let's note that with the minimal use of drugs, attacks are easier to control, and their number decreases.

Keto diet harm to health: contraindications

You have to remember that no matter how good the keto diet is, it might not be right for you.There are some contraindications that you should be aware of.

• Many people consider the first disadvantage to be the long period of entering ketosis.For some it can last up to ten days, while for others the body does not rebuild at all.Then fatigue may occur.
• The keto diet does not include grains, bread, fruit, potatoes, or other fiber-rich foods.Due to its deficiency, disorders in the gastrointestinal tract may occur.For this type of disease, this food is strictly prohibited.
• If you have type 1 diabetes, you cannot eat according to the principles of the ketogenic diet.
• Diseases of the liver, kidneys, cholecystitis will be an obstacle to the use of such a diet.
• For cardiovascular disease, the keto diet is also not recommended.

In any case, before starting a diet, you should definitely consult your doctor.He will prescribe tests, tests, and studies that will show exactly whether you can use a low-carb diet or whether it is better to abandon this idea immediately.

Keto diet rules: tips for getting in and out, side effects

The main postulate

This diet is based on the principle of absorbing as much fat as possible, with an extreme limitation of carbohydrates, as we have said.However, not everyone can enter extraordinary mode comfortably.Therefore, experts give advice on what to do, where to start and the rules to follow.Let's summarize everything we've learned so far.

• Pay attention to carbohydrates, avoid them completely if possible.After all, they not only provide an excessive amount of energy that the body cannot process, but can also disrupt metabolism and cause various diseases.
• Choosing vegetables on a keto diet doesn't mean switching to potatoes and carrots.In any case, they are not allowed.It is better to forget about all the starchy gifts of vegetable gardens and gardens once and for all.Priority should be given to green vegetables that grow on the ground.
• Eating healthy fats should not be limited to butter and meat.Take advantage of every opportunity, for example, by consuming more fatty fish, seafood, avocados, olives, etc.
• Fans of the keto diet mostly learn to cook on their own, which is undoubtedly an advantage.Due to your choice of food, going to a cafe or restaurant will be difficult, because it is not a fact that the menu there will be adapted to your liking.In addition, you may not be able to guess the quality and composition of some dishes.Little things like that can "knock you out" of ketosis for a week, which is why you need to try again.Cook at home so you can be sure that everything is fine.
• Use a variety of vitamin complexes, supplements, and fermented foods during the keto diet.This will help your gastrointestinal tract, as well as the rest of the body, to receive part of the missing substances, macro and micro elements, vitamins and others.
• Water is the basis of life.You need to drink it always, everywhere and a lot, especially on a difficult diet like the ketogenic diet.If it is difficult to learn how to do this, set yourself a "reminder" and drink 100-200 grams every hour.

For some people on the keto diet, the idea of fasting is unacceptable.However, intermittent systems are quite accessible to everyone.This means that on the chosen day you give yourself a corridor at eight to ten, when you do not take any food at all, but only water.This system will allow you to burn fat deposits better.

Tips before starting a ketogenic diet

Many people are interested in the question of how to enter the mode so that they are smooth and minimal.First, you should correctly calculate the optimal calorie content for the keto diet.This is done based on individual indicators: height, weight, gender, activity, lifestyle.Mainly, you need to maintain the right balance of dietary fats: 70% high quality fat, 20% protein, only 10% carbohydrates.

• Start with water.You should drink at least two liters in the beginning.Ideally, the amount of water absorbed per day should be 2.7 liters for women, and 3.7 for men.
• To replenish the lost sodium, you need to consume about half or a teaspoon of regular table salt every day.
• Do not forget to replenish your magnesium and potassium reserves, otherwise you will not get unpleasant consequences for a long time.
• At first, stop strength training and switch to aerobics or yoga.

With the help of meditation, you can significantly reduce stress, which will help you quickly adapt to the new menu.Look inside yourself, set realistic goals, reflect on your body and spirit, then everything will surely work out.

The right way out

Ketone diet is a special nutritional system.It happened historically that some citizens, for example, the Far North, lived in this regime all their lives from generation to generation.However, some people, having experienced drying or simply losing weight, improving their health or achieving other goals, want to return to their normal lifestyle.

It is better to come off ketoracion gradually than suddenly.The body needs to be given time to switch back to eating carbohydrates and start the glycolysis process.Therefore, it is best to introduce carbohydrate foods one by one without being too fanatical.For example, start with a slice of bread a day, half a grapefruit, or an apple.This will help you not feel any discomfort.

Reviews from experts

Nutritionist

"I think a balanced diet is the most correct. I consider the keto diet extreme, suitable only for athletes trying to lose as much fat as possible before the competition, and also for models before the show. After all, the body is under stress, fully adapting to a different type of nutrition. However, for some reasons, such a diet can be a real savior for a person."

Fitness trainer

"This type of diet is not the most suitable for regular exercise. The diet turns out to be completely unbalanced; the body receives little vitamins, minerals and other "benefits". The keto diet is only suitable for those who have moderate physical activity, and prefer quiet sports to vigorous sports."
