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

Almost every man and woman dreams of becoming the owner of a beautiful, fit and slim body.Fashion trends dictate their laws and offer hundreds of ways to lose weight and dry the body.These miracle drugs and methods of shedding extra kilos often turn out to be insecure and do not deserve attention.However, there are many effective options, one of which is the keto diet for weight loss, which has been tested by many people based on 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, depleting our bodies, which leads to anorexia, which is extremely dangerous to health.Others exhaust themselves with strength training, but still cannot achieve a toned body.This is because it is better to act comprehensively, combining proper nutrition and moderate physical activity.One of the progressive nutritional systems is ketogenic, which will be discussed in our article.

The keto diet (also called ketogenic or ketone) is an extremely low-carb diet.At the same time, the diet is dominated by fats and a moderate amount of protein(s).

Brief history

At the beginning of the twenties of the 20th century, doctors faced a serious problem - the treatment of epileptic seizures proved to be ineffective.In the background of their usual lifestyle, the patients regularly had seizures.Then nutritionists developed a completely new nutritional system that helped alleviate symptoms and minimize crises.Over time, it became clear that along with the seizures, excess subcutaneous fat began to melt.

Ten to fifteen years later, anticonvulsant drugs were introduced to help epileptics control their seizures.However, an American cardiologist, Robert Atkins, invented a diet for weight loss based on previous developments.True, his version included carbohydrates and didn't compromise on protein, which prevented the body from staying in ketosis, which is what the entire harmonic system of the modern keto diet is based on.

In the late nineties, American director Jim Abrahams decided to share the story of his son's struggle with epilepsy.Due to the intolerance of certain medications and their "side effects", the boy could not take the prescribed medications.The ketogenic diet helped him find a way out, which Jim made a well-known movie 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 is the state of ketosis

Where did the wild popularity of such an energy system come from, and why does it actually work?Our body typically obtains energy "fuel" from carbohydrates, turning them into glucose.It also nourishes the neurons of the brain.However, if there is a lack of this product, 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 the feeling of 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 no longer receives carbohydrates as its only source of energy, it turns to the same fat reserves that it saved for a rainy day.It is processed by the liver and broken down into glycerol and fatty acids.They then form ketone bodies, which fuel the body and brain.

The process is called metabolic ketosis.This occurs around the seventh day of the diet.Then the body stops the process of processing glucose (glycolysis), using the reserves of the muscles, liver and other tissues, while simultaneously activating lipolysis - the high-quality breakdown of fats.

The peculiarity of this type of nutrition is that we can lose weight by burning our own fat reserves.After all, there is no carbohydrate supply.In this case, the protein tissue remains intact.In other words, such a diet is excellent both for simple weight loss and for those who practice sports that require special endurance (heavy weights, marathon, triathlon).

Types of keto diet

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

1. Standard.This is the most accessible diet when carbohydrates are gradually reduced to an extreme minimum.It is suitable for everyone who plays sports or is involved in fitness.The main principle here will be the refusal of the so-called refeeds (acceptable days of carbohydrate consumption).It provides a very efficient and constant amount of calories.
2. Aimed or targeted.For this type, "load" days are acceptable, when it is acceptable to eat foods rich in carbohydrates.For example, to eliminate drowsiness or fatigue during periods of intense training, such as before a competition.
3. Cyclic.This option is considered the most advanced and is not available to everyone.With such a diet, you must independently determine when to replace the carbohydrate reserve, which is needed, for example, during intense training or when the body is exhausted.This means a return to ketosis when balance is restored.

Nutritionists recommend that you start with a regular diet, but if you feel sick, switch to a lighter diet.

Stages of adaptation of the body: advantages and disadvantages

Due to differences in genetic makeup, everyone's path to ketosis is different.There are those who get it in three or four days and don't leave it for a month without problems, while others can't achieve results even after a week.You don't have to worry and overdo it, giving up halfway through the process.The most important thing is to understand what is happening in the body, where to start with the keto diet, and how to deal with negativity.

What happens to the body: main phases and keto flu

To get your body used to ketosis, you have to go through a difficult journey with many changes.

First phase: 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 feeding on glucose, which was abundantly left over from previous meals.Due to the lack of injected carbohydrates, the insulin level decreases, which is why there is excessive urination.This is because sodium and water are discarded as excess ballast.Some people experience mild dehydration with all its "charms" such as dizziness, fatigue and irritability.

Second phase: gluconeogenesis

When carbohydrate reserves are depleted, the body enters a second phase, which lasts two to ten to fourteen days on a 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, the muscle will be the first source of energy.

In the second phase, the body loses so much sodium and water that many people experience strange, flu-like symptoms.You may experience unexplained headaches, fatigue, and want to lie down and do nothing.Dizziness, joint pain, nausea and weakness are common.Don't worry, these symptoms have nothing to do with viral illnesses or colds.Below are recommendations on how to ease into the metabolic state of ketosis.

Phase Three: Ketosis in person

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

Indications for use and benefits

There are many advantages to using such an energy system.Everyone finds their own advantages.The medical indications for switching to a keto diet are also varied.These points need to be addressed in more detail.

• The body uses its own subcutaneous fat as an energy source, as well as deposits on internal organs.Therefore, the effect of extremely rapid weight loss can be observed.
• Due to low-carbohydrate foods, the body itself lowers blood sugar.This means 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 switch to the keto diet to improve their mental abilities, increase concentration and improve mental focus.According to the latest studies, fatty foods consumed also have a beneficial effect on brain function.
• The link between being overweight and high blood pressure is undeniable.Therefore, you can normalize it at the same time as losing excess fat.
• In ketosis, the feeling of hunger decreases significantly, fatty foods fill you up better and for a longer period of time.

Harmful effects of the keto diet: contraindications

Keep in mind that no matter how good the keto diet may seem, it may not be right for you.There are several contraindications to be aware of.

• Many consider the first disadvantage to be the long period of entering ketosis.For some, it can take up to ten days, while for others, the body does not recover at all.Then comes exhaustion.
• The keto diet does not include grains, bread, fruit, potatoes, or other high-fiber foods.Due to its deficiency, disorders may occur in the gastrointestinal tract.In the case of this type of disease, this food is strictly contraindicated.

The rules of the keto diet: tips for getting in and out, side effects

Main postulates

The diet of this diet is based on the principle of absorbing as much fat as possible, with extreme restriction of carbohydrates, as already mentioned.However, not everyone can comfortably enter such an unusual mode.Therefore, experts advise what to do, where to start and what rules to follow.Let's summarize everything we've learned so far.

• Pay attention to carbohydrates, if possible avoid them completely.After all, they not only provide an excessive amount of energy that the body cannot process, but they can also disrupt metabolism and cause various diseases.
• Choosing vegetables on the keto diet does not mean switching to potatoes and carrots.Under no circumstances should they be allowed to.It is better to forget once and for all all the starchy gifts of vegetable gardens and gardens.Preference should be given to green vegetables that grow above the ground.
• Eating healthy fats should not be limited to butter and meat.Take advantage of every opportunity, such as eating more fatty fish, seafood, avocados, olives, etc.
• Keto dieters mostly learn to cook themselves, which is undoubtedly a plus.Due to your food preference, it will be difficult to go to a cafe or restaurant, because it is not a fact that the menu there will be adapted to your needs.In addition, you may not be able to guess the quality and composition of some foods.Such a trifle can "knock" out of ketosis for up to a week, so you have to make efforts again.Cook at home so you can be sure everything is fine.
• During the keto diet, use various vitamin complexes, dietary supplements and fermented foods.This helps the gastrointestinal tract, as well as the whole body, to receive the missing substances, macro- and microelements, vitamins and other things.
• Water is the basis of life.You need to drink always, everywhere and a lot, especially on a diet as difficult as ketogenic.If it's hard to learn how to do this, set yourself a "reminder" and drink 100-200 grams every hour.

For some people on the keto diet, even the thought of fasting is unacceptable.However, the periodic system is available to everyone.This means that on the chosen day, between eight and ten o'clock, you designate a corridor for yourself, when you buy no food at all, only water.This system enables even better burning of fat deposits.

Tips before starting the ketogenic diet

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

• Start with water.First you need to drink at least two liters.Ideally, the amount of water absorbed per day is 2.7 liters for women and 3.7 liters for men.
• To replace lost sodium, consume about half to a teaspoon of regular table salt daily.
• Do not forget to replenish your magnesium and potassium reserves, otherwise there will be no unpleasant consequences for a long time.
• First, give up 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, look at your body and soul, then everything will definitely work out.

The right way out

The keto diet is a special nutritional system.Historically, it has happened that some nationalities, such as those from the Far North, have lived in this system for their entire lives from generation to generation.However, some people want to go back to their normal lifestyle after going through drying or simply losing weight, improving their health or achieving other goals.

It is better to withdraw from ketorion gradually rather than suddenly.The body must be given time to return to carbohydrate consumption and to start the process of glycolysis.Therefore, it is best to introduce carbohydrate-containing foods one after the other without any particular fanaticism.For example, start with a slice of bread, half a grapefruit or an apple a day.This will help you not feel uncomfortable.

Keto Diet Results: Side Effects and Expert Opinion

Usually, those who have tried the keto diet talk about rapid weight loss and cutting.Their bodies become more toned, excess fat residues under the skin melt away without a trace, so the muscles become more prominent and beautiful.The functioning of all body systems improves, the metabolism normalizes, the skin, hair, and nails become healthier.

However, some side effects do occur, such as those described at the beginning of this article.But if the lack of hunger can be considered a plus, then there is hardly any smell of acetone from the mouth.If this happens in the first week or two, there is nothing to worry about.If the process is prolonged, it is time to consult a doctor.

Reviews from experts

Nutritionist

"I think a balanced diet is the best. I consider the keto diet to be extreme, it is only for athletes who want to lose as much fat as possible before competitions and models before shows. After all, the body experiences stress and adapts completely to a different kind of nutrition. However, for certain medical reasons, such a diet can be a real salvation for a person. I think that the keto diet should be kept under the strict supervision of a specialist."

Fitness trainer

"This type of nutrition is not the most suitable for regular intense exercise. It turns out that the diet is completely unbalanced, the body receives few vitamins, minerals and other "beneficial effects". Keto nutrition is only suitable for those who are moderately physically active and prefer calm sports to intense sports."
