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

Almost all men and women want to have a beautiful, fit and slim body.Fashion trends dictate their own laws, offering hundreds of ways to lose weight and tone the body.Often these miraculous means and ways to lose extra pounds are a dummy that does 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 from their own experiences.

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

Striving for thinness, we are ready to take the most radical measures, sometimes exhausting our body, leading it to anorexia, which is extremely dangerous for 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 advanced nutritional systems is the ketogenic system, 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 as well as a moderate amount of protein(s).

Brief history

In the early twenties of the 20th century, doctors faced a serious problem - the treatment of epileptic seizures was ineffective.Against the background of their usual lifestyle, patients regularly had attacks.Then nutritionists developed a completely new nutritional system that helps eliminate symptoms by minimizing crises.Over time, it became clear that along with the seizures, the subcutaneous fat also began to melt.

Ten to fifteen years later, anticonvulsant drugs were introduced to help epileptics control their seizures.But cardiologist Robert Atkins from the United States invented a diet for weight loss based on previous developments.True, his version contained carbohydrates and did not compromise on proteins, which prevented the body from remaining in the state of ketosis, on which the entire harmonious system of the modern keto diet is based.

In the late 90s, American director Jim Abrahams decided to share the story of his son's struggle with epilepsy.Due to intolerance to certain drugs, as well as "side effects" from them, the boy could not take the prescribed drugs.The ketogenic diet helped him find a way out, about which Jim made a famous film "Do No Harm" with Meryl Streep in the lead role.Thus, the keto diet went beyond a purely medical phenomenon and became known to the public.

The essence of the keto diet: the state of ketosis

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

Studies have shown that the ketogenic diet suppresses the body's production of the hormone ghrelin.It is he who 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 such a pleasant side effect of ketosis.

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

The process is called metabolic ketosis.It occurs approximately on the seventh day of the diet.Then the body stops the process of processing glucose (glycolysis) using the reserves of muscles, liver and other tissues, and at the same time activates lipolysis - the high-quality breakdown of fats.

The peculiarity of this type of nutrition is that you can lose weight by burning your fat reserves.After all, carbs are not filling.In this case, the protein tissue remains intact.That is, such a diet is very suitable both for losing weight and for those who do sports that require special endurance (heavy weights, marathon, triathlon).

Types of keto diet

The main characteristic of the ketogenic diet is a varied diet, depending on the capabilities of your body.There are three main types of diet.

1. Standard.This is the most accessible type of diet when carbohydrates are gradually reduced to an exceptional minimum.Suitable for anyone involved in sports or fitness.The main principle here will be the so-called abstinence (days when carbohydrate consumption is acceptable).It is highly effective and provides a constant amount of calories.
2. Targeted or targeted.In this type, "loading" days are acceptable, it is acceptable to eat carbohydrate-rich foods.For example, during periods of intense training, for example, to overcome drowsiness or fatigue before a competition.
3. Periodic.This option is considered the most advanced and is not available to everyone.With such a diet, for example, during intense training or exhaustion of the body, you need to independently determine the time to replenish the supply of carbohydrates.This involves returning to ketosis when the balance is restored.

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

Stages of adaptation of the body: pros and cons

Due to differences in genetic makeup, each person has a different journey to ketosis.Some can come in three or four days and leave for a month without problems, while others can not get results even after a week.There is no need to worry and go to extremes, giving up halfway through the process.The main thing is what happens in the body, where to start the keto diet and how to deal with the negatives.

What's Happening in the Body: Key Stages and the Keto Flu

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

First stage: glycogen depletion

The first stage occurs between the sixth and twenty-fourth hours after the beginning of the ketogenic diet.The body is still actively feeding on glucose left over from previous meals.Due to the lack of injected carbohydrates, the insulin level decreases, so there is excessive urination.This is because sodium and water are thrown away as unnecessary ballast.Some experience moderate dehydration with all its "charms" such as dizziness, fatigue and irritability.

Second stage: gluconeogenesis

When carbohydrate stores are depleted, the body enters the second phase of the keto diet, which can last from two to fourteen days.The cycle 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, muscle is the first source of energy.

In the second phase, along with water, the body loses so much sodium that many begin to experience strange flu-like symptoms.You may feel an unreasonable headache, fatigue, and you want to lie down and do nothing.Dizziness, painful joints, nausea and weakness are common.Do not worry, these symptoms have nothing to do with viral diseases or colds.Below are tips on how to ease yourself into the metabolic state of ketosis.

Third stage: personal ketosis

This period can occur from the third to the fourteenth day after 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.

Directions for use and benefits

There are many advantages to using such a power system.Everyone will find their preferences.Medical indications for switching to a keto diet also vary.It is necessary to dwell on these points in more detail.

• The body uses its own subcutaneous fat as a source of energy, and it also accumulates in the internal organs.Therefore, the effect of extremely fast weight loss is observed.
• Depending on the type of low-carb food you eat, your body will naturally lower your blood sugar levels.It is a good prevention and treatment of diabetes.
• 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 recent studies, fatty foods consumed also have a beneficial effect on brain activity.
• The link between excess weight 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 keep you fuller for longer.
• The condition of the skin improves significantly due to a decrease in the level of subcutaneous sebum.It has a beneficial effect in removing acne and pimples.

Much has already been said and written about the benefits of this nutritional system for people suffering from epilepsy.Just note that with minimally used drugs, attacks are easier to control and their number decreases.

Keto diet harm to health: contraindications

You should remember that no matter how good the keto diet may seem, it may not be right for you.You should know that there are a number of contraindications.

• Many people consider the first disadvantage to be the long time it takes to enter ketosis.For some, it can last up to ten days, and for others, the body does not rebuild at all.Then fatigue can begin.
• 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 diseases, this food is strictly contraindicated.

Rules of the keto diet: instructions for entry and exit, side effects

Basic postulates

The diet of this diet, as we have already said, is based on the principle of absorbing as much fat as possible with extreme restriction of carbohydrates.But not everyone can comfortably enter such an unusual regime.Therefore, experts give advice on what to do, where to start and what rules to follow.Let's summarize everything we have 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 can even disrupt metabolism and cause various diseases.
• Choosing vegetables on a keto diet does not mean switching to potatoes and carrots.They should not be allowed under any circumstances.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 ground.
• Eating healthy fats should not be limited to butter and meat.Take advantage of every opportunity, for example, more oily fish, seafood, avocados, olives, etc.
• Fans of the keto diet mostly learn to cook themselves, which is definitely a plus.It will be difficult to go to a cafe or restaurant with regard to your food preferences, because it is not the fact that the menu there will be tailored to you.In addition, you will not be able to predict the quality and composition of some dishes.Such a small thing can "knock" you out of ketosis for a week, and you will have to make an effort again.Cook at home to make sure everything is good.
• Use various vitamin complexes, dietary supplements and fermented foods during the keto diet.This will help your gastrointestinal tract, as well as your whole body, to receive the missing part of substances, macro and microelements, vitamins and other things.
• Water is the basis of life.You need to drink it always, everywhere and a lot, especially on a difficult diet like ketogenic.If it is difficult to learn how to do this, set yourself a "reminder" and drink 100-200 grams every hour.

For some on the keto diet, even the thought of fasting is unacceptable.However, the intermediate system is quite accessible to everyone.This means that if you don't eat anything on the day you choose, you set yourself a corridor from eight to ten when you only drink water.This system will allow to burn fat deposits even better.

Tips before starting a ketogenic diet

Many people are interested in the question of how to enter the mode to become smooth and minimal.First, you need to correctly calculate the optimal amount of calories for the keto diet.This is done based on individual indicators: height, weight, gender, activity, lifestyle.Basically, you will 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 should be 2.7 liters for women and 3.7 for men.
• To replace lost sodium, you should consume about half to one teaspoon of regular table salt per day.
• Do not forget to replenish your magnesium and potassium reserves, otherwise you will not get pleasant results 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, think about your body and soul, then everything will definitely work out.

The right way out

The keto diet is a special nutritional system.Historically, some peoples, for example, the Far North, live in this mode from generation to generation throughout their lives.However, some want to return to their normal lifestyle after drying or simply losing weight, improving their health or achieving other goals.

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

Keto Diet Results: Side Effects and Expert Opinion

Usually those who try the keto diet talk about rapid weight loss and cutting.Their bodies become more toned, unnecessary fat residues under the skin melt without leaving a trace, and the muscles become more prominent and beautiful.The activity of all body systems improves, metabolism normalizes, skin, hair, nails become healthy.

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

Reviews from experts

Nutritionist

"I think that a balanced diet is the most correct. I consider keto nutrition to be extreme, it is suitable only for athletes trying to lose as much fat as possible before competitions, as well as for models before shows. After all, the body experiences stress by completely adapting to a different type of nutrition. However, for some medical reasons, such a diet can be a real salvation of a keto diet for a person. a real specialist".

Fitness trainer

"This type of nutrition is not the most suitable for regular intensive training. The diet is completely unbalanced; the body receives little vitamins, minerals and other "benefits".
