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

Almost all men and women dream of becoming the owner of a beautiful, fit and slim body.Fashion trends dictate their own laws, offering hundreds of methods for losing weight and drying the body.Often, these miracle drugs and ways to lose extra pounds turn out to be a dummy, unworthy of attention.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 nutrition system

In search of weakness, we are sometimes ready to take the most radical measures, impoverishing our body, leading it to anorexia, which is extremely dangerous to health.Others tire of 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 one, which will be discussed in our article.

The keto diet (also called ketogenic or ketonic) is an extremely low carb diet.At the same time, the diet is dominated by fats, 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 usual lifestyle, attacks regularly occurred in patients.Then nutritionists developed a completely new nutritional system that helped relieve symptoms, minimizing seizures.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.But a cardiologist from the United States, Robert Atkins, invented a diet for weight loss, based on previous developments.True, his version contained carbohydrates and did not compromise on protein, which prevented the body from staying in a state of ketosis, on which the entire harmonious system of the modern keto diet is based.

In the late nineties, the American director Jim Abrahams decided to tell 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 drugs.The ketogenic diet helped him find a way out, for which Jim made a popular film called "Do No Harm" with Meryl Streep in the lead role.Thus the keto diet went beyond a purely medical phenomenon and became public knowledge.

The essence of the keto diet: the state of ketosis

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

Research has 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 nice side effect of ketosis.

When our body stops using carbohydrates as its sole source of energy, it turns to the same fat stores it has been saving for a rainy day.They are processed by the liver, breaking down into glycerol and fatty acids.They then form ketone bodies, which fuel 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 reserves from 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 you can lose weight by burning your fat reserves.After all, there is no carb recharging.In this case, the protein tissue remains intact.That is, such a diet is suitable both for simple weight loss and for those who engage in sports that require special endurance (heavy weights, marathons, triathlons).

These types of diet

The main characteristic feature 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 incredible minimum.It is suitable for anyone involved in sports or fitness.The main principle here will be the rejection of the so-called refeeds (days on which the consumption of carbohydrates 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 foods rich in carbohydrates is acceptable.For example, to eliminate drowsiness or fatigue during periods of intense training, for example, before a competition.
3. Cyclic.This option is considered the most advanced and not available to everyone.With such a diet, you must independently determine when it is time to replenish the supply of carbohydrates, which are needed, for example, during intense training or exhaustion of the body.This means a return to ketosis when balance is restored.

Nutritionists recommend starting with a standard diet, but if you don't feel well, switch to milder regimens.

Stages of body adaptation: pros and cons

Due to differences in genetic makeup, each person has a different journey to ketosis.Some can get it in three or four days and not leave it without a problem for a month, while others can not achieve 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 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 stages and these flus

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

First phase: Glycogen depletion

The first phase occurs between six and twenty-four hours from the start of the ketogenic diet.The body still actively feeds on glucose, which is left in abundance from previous meals.Due to the lack of injected carbohydrates, the level of insulin decreases, therefore 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 phase: gluconeogenesis

When carbohydrate stores are depleted, the body enters a second phase, which can last anywhere from two to ten to fourteen days on a keto diet.A 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 as well as water that many begin to experience strange flu-like symptoms.You may experience an unreasonable headache, fatigue and 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 viral diseases or colds.Below are recommendations on how to more easily put yourself 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 reached no later than the tenth day, but it all depends on lifestyle and genetic characteristics.

Indications for use and benefits

Using such an energy system has a large number of advantages.Everyone will find their own advantages.The medical indications for switching to a keto diet are also different.It is necessary to dwell on these points in more detail.

• The body uses its subcutaneous fat as a source of energy, and also stores it in the internal organs.Therefore, the effect of extremely rapid weight loss is observed.
• Because of the low carbohydrate type of food you consume, the body itself will lower 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 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 function.
• The relationship between excess weight and high blood pressure is undeniable.Therefore, while losing excess fat, you can normalize it at the same time.
• In a state of ketosis, the feeling of hunger is significantly reduced and fatty foods fill you up better, for a longer time.
• The condition of the skin improves significantly due to the decrease in the level of subcutaneous sebum.This has a beneficial effect on the elimination of acne and acne.

Much has already been said and written about the benefits of this nutritional system for people with epilepsy.Let's just emphasize that with minimally used medications, attacks are easier to control and their number is reduced.

Harm of the keto diet for health: contraindications

You have to remember that no matter how good the keto diet looks, it may not be right for you.There are a number of contraindications that you should be aware of.

• Many people consider the first disadvantage to be the long period of entry into ketosis.For some it can take up to ten days, while for others the body does not rebuild at all.Then exhaustion can set in.
• The keto diet does not include grains, breads, fruits, potatoes, or other high-fiber foods.Due to its lack, disturbances may occur in the gastrointestinal tract.For diseases of this type, this diet is strictly contraindicated.
• If you have type 1 diabetes, you cannot eat according to the principles of a ketogenic diet.
• Diseases of the liver, kidneys, cholecystitis will become an obstacle to the use of such a diet.
• For cardiovascular diseases, the keto diet is also not recommended.

In any case, before starting a diet, you should definitely consult your doctor.He will describe 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 postulates

The diet of this diet is based on the principle of absorbing as much fat as possible, with extreme restriction of carbohydrates, as we have already said.However, not everyone can easily enter in such an unusual way.Therefore, experts give advice on what to do, where to start and what rules to follow.Let's recap everything we've learned so far.

• Pay attention to carbohydrates, avoiding them completely if possible.After all, they not only provide an excessive amount of energy that the body is unable to process, but can even disrupt the metabolism and cause various diseases.
• Choosing vegetables on a keto diet does not mean switching to potatoes and carrots.In no case should they be allowed.It is better to forget once and for all all the starchy gifts of gardens and vegetable gardens.Preference should be given to green vegetables that grow above ground.
• Eating healthy fats doesn't have to be limited to butter and meat.Take advantage of every opportunity, for example, by consuming more fatty fish, seafood, avocados, olives, etc.
• Keto dieters mostly learn to cook themselves, which is definitely a plus.Because of your food preferences, 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 you.In addition, you may not be able to guess the quality and composition of some dishes.Such a small thing can "knock" you out of ketosis for a week, so you will have to make an effort again.Cook at home to make sure everything is in order.
• Use various vitamin complexes, dietary supplements and fermented foods during the keto diet.This will help your gastrointestinal tract, as well as the whole body, to receive the missing part of substances, macro- and microelements, vitamins and other things.
• Water is the basis of life.You have to drink it always, everywhere and a lot, especially on a diet as difficult as the ketogenic one.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 idea of fasting is unacceptable.However, the intermittent system is quite accessible to everyone.This means that on the chosen day you assign yourself a corridor from eight to ten o'clock, when you receive no food at all, only water.This system will allow you to burn fat deposits even better.

Tips before starting the ketogenic diet

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

• Start with water.In the beginning you should 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 replenish lost sodium, you should consume about half or a full teaspoon of common salt per day.
• Do not forget to replenish your reserves of magnesium and potassium, otherwise you will not have unpleasant consequences for a long time.
• At first, give up strength training and switch to gymnastics 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, meditate on your body and soul, then everything will definitely work out.

The right way out

The keto diet is a special food system.It so happened historically that some nationalities, for example, those of the Far North, live in this regime all their lives from generation to generation.However, some, after undergoing dehydration or simply losing weight, improving their health or achieving other goals, want to return to their usual lifestyle.

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

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, the remains of unnecessary fat under the skin melt without leaving a trace, making the muscles more prominent and beautiful.The functioning of all body systems improves, metabolism normalizes, skin, hair, nails become healthier.

However, it happens that some side effects appear, such as those described at the beginning of the article.But if the lack of hunger can be considered a plus, then the smell of acetone from the mouth is not difficult.If this happens in the first week or two, there is nothing to worry about.If the process drags on, then it's time to go to the doctor.

Reviews by experts

Nutritionist

"I think that a balanced diet is the most correct. I consider the extreme keto diet 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, fully adapting to a different type of nutrition. However, for some medical reasons, such a diet can be a real salvation for a person.

Fitness trainer

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