Introduction to the Ketogenic Diet for Beginners

The ketogenic diet, or keto diet, is a general name for low-carbohydrate diets that transform the body into a fat-burning machine. While ketogenic diets offer many benefits in terms of weight loss, health, and performance, they can sometimes have side effects in the initial stages.

Ketogenic diets are similar to other low-carbohydrate diets such as the Atkins diet or LCHF (low-carbohydrate, high-fat) diets, as they all share ketogenic characteristics. The main difference between LCHF (low-fat) diets and ketogenic diets is the restriction of protein intake in ketogenic diets.

Ketogenic diets are designed to put the body into ketosis. Besides health and weight loss, it's possible to achieve the necessary and sufficient ketone levels the body needs to improve physical and mental performance. Whatever your goal, you can find all the details on how to follow a ketogenic diet below.

1. Introduction: What is ketosis?

The "keto" in the ketogenic diet comes from the fact that it stimulates the body to produce small energy molecules called "ketones." Ketones are an alternative energy source used when blood sugar, or glucose, is low.

Ketones are produced in the liver using fat when you consume very few carbohydrates or small amounts of protein. They are then used as an energy source for all organs in the body, including the brain. The brain, being an organ that uses a large amount of energy every day, cannot directly utilize fat. Its energy source can only be glucose or ketones.

When you follow a ketogenic diet, your entire body changes its energy source and begins to function almost exclusively using fat. Insulin levels drop significantly, and fat burning increases dramatically. The body finds it easier to access fat cells for burning. This is an excellent opportunity, especially for weight loss. Ketogenic diets also have less noticeable benefits, such as feeling less hungry or providing the body with a stable energy source.

The state in which the body produces ketones is called ketosis. The fastest way to enter ketosis is... fasting This is called fasting; that is, not eating anything. However, it is not possible to remain hungry forever.

On the other hand, ketogenic diets can be followed indefinitely and put the body into ketosis. So when you follow a ketogenic diet, fastingIt offers all the benefits, including weight loss, and you won't go hungry.

Who should not follow a ketogenic diet?

While ketogenic diets are a safe eating plan for many people, caution may be needed in certain specific situations:

• In diabetic patients who require insulin or medication,
• In people being treated for high blood pressure
• In breastfeeding women.

1. What should you eat while following a ketogenic diet?

The most important condition for reaching ketosis is to stop carbohydrate consumption. Consuming less than 50 grams of net carbohydrates per day is sufficient to enter ketosis, while the ideal amount is 20 grams. The less carbohydrates you consume, the more effective your diet will be.

Do not eat these:

Foods to avoid on a ketogenic diet can be summarized as foods rich in starch and sugar, and starchy foods (such as bread, pasta, rice, or potatoes). This is because these foods are rich in carbohydrates.

What should we drink?

So what should you drink on a ketogenic diet? Water is a great option, as are coffee and tea. Ideally, your drinks should be unsweetened. You can enjoy your tea and coffee with a small amount of milk or cream; and occasionally, a glass of wine.

The fewer carbohydrates you consume while following a ketogenic diet, the more your diet will affect your weight and blood sugar levels. The keto diet is a very strict low-carbohydrate diet and is quite effective.

1. Why the ketogenic diet?

The benefits of a ketogenic diet are similar to those of any low-carbohydrate diet. However, because protein intake is more restricted in ketogenic diets, its effects are greater. Reduced protein intake increases ketone production while decreasing insulin, a hormone that stores fat.

Weight loss effect

Ketogenic diets are highly effective for weight loss because they transform your body into a fat-burning machine. While following a ketogenic diet, insulin levels drop significantly, accelerating fat burning. This creates the ideal conditions for losing weight without feeling hungry.

The results of more than 20 scientific studies show that ketogenic diets are more effective than other diets for weight loss. 

Type 2 diabetes

Since ketogenic diets eliminate the negative effects of high insulin levels, they are also quite effective in combating type 2 diabetes.

Increased ability to focus.

In ketosis, the brain receives a regular flow of ketones, which are energy molecules. Ketogenic diets also eliminate large fluctuations in blood sugar levels. This generally results in improved focus and concentration. This effect of ketosis is the main reason why many people follow a ketogenic diet.

It is commonly believed that carbohydrate consumption is necessary for proper brain function. However, this is only true in a scenario where ketones are absent. Once your body adjusts to the ketogenic diet (you may experience loss of concentration, headaches, and restlessness during the adjustment period), your body and brain can utilize ketones effortlessly. This results in increased energy and concentration.

Improved physical performance

Ketogenic diets It greatly increases your physical endurance because it provides unlimited access to energy produced in your body's fat stores. While the body's carbohydrate reserves in the form of glycogen only last for a few hours during exercise, your fat stores can last for weeks or even months.

When your body is primarily accustomed to burning carbohydrates, your fat stores become less accessible and therefore cannot supply your brain as an energy source. This leads to needing to eat constantly before, during, and after prolonged exercise. Often, you end up eating simply to prevent hunger and generate the energy needed for your daily activities.

In ketogenic diets, this problem disappears. Your body and brain can be nourished 24/7 by your robust fat reserves. Of course, this is provided you consume sufficient salt and fluids and give your body the time it needs to adjust to a ketogenic diet.

Metabolic syndrome

Numerous studies show that low-carbohydrate diets improve indicators of metabolic syndrome. These indicators include blood lipids, insulin levels, HDL, LDL particle size, and fasting glucose. These effects are even more pronounced when you are in ketosis by regularly following a low-carbohydrate, low-protein diet.

Epilepsy

The ketogenic diet is a proven medical therapy for epilepsy that has been used since the 1920s. It is often used for children with epilepsy that cannot be controlled despite other treatments.

Ketogenic diets have recently been tested in adults with epilepsy and positive effects have been observed. Numerous controlled trials have shown how effective ketogenic diets are in reducing epileptic seizures.

In the treatment of epilepsy, the ketogenic diet allows patients to take fewer anti-epileptic drugs while also reducing seizures. In some cases, seizures have completely disappeared without medication using the ketogenic diet. Since all anti-seizure treatments have side effects such as drowsiness, decreased concentration, personality changes, and a drop in IQ, reducing medication use is crucial.

Benefits of ketogenic diets

Ketogenic diets have many benefits in addition to those listed above. For example, did you know that low-carbohydrate diets normalize blood pressure, promote less acne formation, and help control migraines?

Ketogenic diets and low-carbohydrate diets:

• It soothes your stomach,
• It balances blood pressure,
• It reduces acne problems.
• It reduces heartburn.
• It reduces migraine attacks.
• It reduces cravings for sweets.
• It is beneficial for polycystic ovary syndrome.
• It can be used in the treatment of brain cancer.

It is also used in the treatment of common and difficult-to-treat diseases such as Alzheimer's, Parkinson's, and cancer.

1. How do you know if you are in ketosis?

You can determine if you are in ketosis with a urea, blood, or breath test. Some indicators of ketosis that don't require a test include:

• Dry mouth and increased need to drink water: When you don't drink enough water, you don't absorb electrolytes like salt, which are found in water, and therefore you experience dry mouth. Make sure you drink enough water.
• Increased need to use the toilet: Acetoacetate, a type of ketone, increases your need to urinate, allowing ketosis to be tested with urine strips. This increased need to urinate, especially initially, is also one of the main reasons you'll feel more thirsty.
• Keto breath: Keto breath is a condition caused by a type of ketone called acetone, which is exhaled through your mouth, resulting in your breath sometimes smelling sweet.

Here are some other positive indicators that can help you understand if you are in ketosis:

• Reduced feeling of hunger: Many people following a ketogenic diet report a noticeable decrease in appetite and hunger. This is because the body's ability to burn fat stores increases during a ketogenic diet. Many people eat only once or twice a day, essentially achieving a ketogenic diet. intermittent fasting This method saves both time and money, while also accelerating weight loss.
• Energy boost: When you start a ketogenic diet keto flu After overcoming the fatigue that can last for a few days, you'll experience a significant increase in your energy levels. This can also be felt as improved concentration and alertness.

How do you measure ketosis?

There are three different methods for measuring ketosis, that is, the levels of ketones in your body:

1. Urine strips
2. Breath ketone analysis
3. Blood ketone scale

Urine strips The easiest and most affordable way to measure ketosis, especially for beginners. To perform the test, dip the strip in your urine and wait for about 15 seconds. The color change that occurs afterward will indicate the presence of ketones.

Urine test strips are readily available at pharmacies. However, urine test strips can be misleading depending on your fluid intake. These tests don't accurately show ketone levels in your body, and because the body, having become accustomed to ketosis, can reabsorb ketones through your urine, they can also be unreliable. Finally, if you've been in ketosis for a long time, the tests may come back negative.

Breath ketone analysis Another effortless way to measure ketone levels. While more expensive than urine strips, it's cheaper than blood tests in the long run and is reusable. Like urine tests, these tests don't give you a precise ketone level, but they use a color code to help you understand your overall level. However, breath analysis isn't always reliable either.

Blood test It allows you to instantly and numerically measure the ketone levels in your blood. Blood tests, which are the clearest way to measure ketones in your body, are unfortunately quite expensive compared to other options. On the other hand, you need to take a blood sample from your finger to perform the test.

1. How to achieve optimal ketosis?

Being in ketosis isn't as clear-cut as black and white; you're either in ketosis or you're not. You can be at different levels of ketosis depending on your dietary plan.

Based on ketone levels in the blood, we can summarize the state of ketosis as follows:

• Below 5 mmol/L While not considered ketosis, the transition to ketosis is generally considered to have begun around 0,2 seconds. However, at this point, your body is not burning fat at its maximum rate.
• at a level of 0,5-1,5 mmol/L You are in a low state of ketosis. While this is positively affecting your weight, your body hasn't yet begun burning fat at its maximum level.
• Around 1,5-3 mmol/LThis is considered optimal ketosis. At this point, you are at your maximum mental and physical performance. Fat burning reaches its peak, and weight loss accelerates.
• 3 mmol/L and above While not considered essential, its effects can be positive or negative. Sometimes this level may indicate that you are not eating enough. In people with type 1 diabetes, it can be caused by insulin deficiency and may require intervention.
• 8-10 mmol/LThis is often a level you can't reach just by following a ketogenic diet. It could mean something is wrong in your body; it can be caused by insulin deficiency in type 1 diabetes. Nausea, vomiting, and abdominal pain are some of the symptoms you might experience. It can result in a condition called ketoacidosis, which requires intervention. If you experience such a result, it's advisable to see a doctor.

How to enter ketosis?

Here are some ways to increase your ketosis level, ranked from most effective to least effective:

• Restricting carbohydrate intake: A daily intake of 20 grams or less is considered a strict low-carbohydrate diet. You don't need to restrict fiber intake to reach ketosis.
• Reducing protein intake: If possible, adjust your protein intake to 1 gram per kilogram of body weight. Especially if you are overweight, you can aim for 1 gram per kilogram of body weight, which is your target weight. The biggest mistake people make while striving to reach optimal ketosis is often consuming more protein than necessary.
• Consume enough fat to feel full. Fat intake is the biggest difference between ketogenic diets and starvation; fat intake is also necessary to achieve ketosis. Fats are also the key factor that makes ketogenic diets sustainable and distinguishes them from starvation.
• Don't snack when you're not hungry. Unnecessary snacking slows weight loss and reduces ketosis levels.
• If necessary intermittent fasting Practice intermittent fasting. Intermittent fasting is highly effective in increasing ketone levels, accelerating weight loss and improving type 2 diabetes.
• Get some exercise. Engaging in any form of physical activity while following a low-carbohydrate diet also increases ketone levels.

1. With a ketogenic diet related recommendations

There are many ways to make ketogenic diets easy and enjoyable. So how do you prepare your favorite keto breakfasts? How can you consume more fat? And what should you be aware of when eating out?

Breakfast

Breakfast is a perfect meal for a ketogenic diet because almost all of us love eating eggs.

Another option is to have just a cup of coffee for breakfast. Since you'll feel less hungry while following a low-carb, high-fat keto diet, you may not feel the need to eat breakfast most of the time.

Main

So what should you do for lunch and dinner? You can consume it with meat, fish, or chicken, along with a sauce rich in saturated fat and plenty of greens.

Eating out

How can you follow a keto diet at a buffet, a friend's house, or a restaurant? The key is to avoid starchy foods like bread or pasta, while making your plate more filling with natural fats like butter or olive oil.

Bread consumption

If you find it difficult to avoid eating bread, you can try low-carb bread recipes that you can find in various sources.

How do you eat more fat?

Fat is a key factor in making the ketogenic diet filling. You can increase your fat intake by cooking your meals with oil, preparing oily sauces, and adding fatty ingredients like cheese or avocado to your recipes.

Dikkat: One of the most common mistakes when following a ketogenic diet is falling into the trap of commercially available "low-carb" products. Remember, an effective ketogenic diet should be based on real foods.

1. Potential side effects of ketosis

When you suddenly stop consuming sugar or starch, you may experience some side effects until your body adjusts. Side effects of the ketogenic diet are generally mild and last for a few days, and it's possible to reduce them.

To reduce the side effects of ketosis first for Your option might be to gradually reduce your carbohydrate intake day by day. However, often eliminating them all at once is more effective. Cutting out sugar and starch from your diet can make a noticeable difference in your weight, even within a few days. While the initial weight loss is usually due to water retention, it's a good source of motivation to start with.

When you first start a strict ketogenic diet, you may experience the following side effects:

Keto flu

The most common side effect reported so far in people following a ketogenic diet is the initial symptoms, also known as keto flu. The most common keto flu symptoms are:

• Headache
• Fatigue
• Dizziness
• Nausea
• Tension

As your body adjusts to the new diet, the effects of these symptoms will lessen, and they will usually disappear completely within a week. Fat burning will also accelerate during this phase.

Keto fluThe main reason for this is that carbohydrate-rich foods increase fluid retention in the body. When you stop consuming high-carbohydrate foods, you will need to urinate more frequently than usual as a large amount of water and salt is excreted through your kidneys along with the fluid. This is especially noticeable in the first week, and it is the main reason for the things mentioned above.

You can minimize the effects of keto flu by consuming more fluids and salt.

Other problems you may encounter while in ketosis

When you enter ketosis, keto In addition to the flu, you may also encounter the following problems:

• Leg cramps,
• Constipation,
• Bad breath
• Heart palpitations
• Performance degradation

Just as keto fluAs with other problems, you can solve these issues by drinking more water and salt.

Less common side effects

• Expert
• Gallbladder problems
• Temporary hair loss
• High cholesterol
• Decreased alcohol tolerance.
• Itching

Common misconceptions about ketogenic diets

When you first start a ketogenic diet, you may experience the side effects listed above. However, there are also many misconceptions and unfounded fears about ketogenic diets; such as the idea that your brain doesn't function properly without carbohydrates, or that these diets cause kidney or thyroid problems.

Another problem is that ketosis, which occurs when following a ketogenic diet, is confused with ketoacidosis, a dangerous health condition. While these two are very different, ketoacidosis is not a condition that can occur solely from following a ketogenic diet.

1. Frequently asked questions about ketogenic diets

What is the difference between low-carbohydrate diets and ketogenic diets?

Ketogenic diets are very strict low-carbohydrate diets; they require restricting protein intake as well, while primarily forcing your body to use fat stores.

A properly implemented low-carbohydrate diet usually results in ketosis. However, ketogenic diets are more precisely designed programs to ensure positive results. In short, the keto diet can be described as a very strict low-carbohydrate diet.

Why couldn't I enter ketosis?

There are two main reasons why you might not be able to enter ketosis: consuming too many carbohydrates and/or too much protein. It's important to remember that the required amounts of carbohydrates and protein to enter and maintain ketosis vary from person to person.

Are high ketone levels necessary to accelerate weight loss?

Both yes and no. Consuming fewer carbohydrates, consuming less protein, and intermittent fasting Doing this supports weight loss because it lowers insulin levels and increases ketone levels.

However, adding extra fat to your diet to increase ketones won't speed up weight loss. Neither will taking MCT oil supplements or ketone supplements. These methods slow down the weight loss process because they offer your body different energy sources.

At what time of day should ketone levels be measured?

To make an accurate comparison, it's helpful to measure your ketone levels at the same time every day. Measuring in the morning, before eating anything, can be more effective for observing the results.

The numbers you get in the mornings are the lowest of the day; they are higher in the evenings. If higher numbers motivate you, you can also take the measurement in the evening.
