The ketogenic diet (or keto diet for short) is a low-carb, high-fat diet that brings many benefits to the body.
In fact, many studies show that this type of diet can help you lose weight and improve your health.
The ketogenic diet may even be beneficial in the treatment of diabetes, cancer, epilepsy, and Alzheimer's disease.
Below is a detailed guide to the keto diet for beginners.
What is the ketogenic diet?
The ketogenic diet is a very low-carb, high-fat diet that has many similarities to the Atkins diet and low-carb diets.
It involves drastically reducing carbohydrate intake and replacing them with fats. This reduction in carbohydrate intake puts your body into a metabolic state called ketosis.
When this happens, your body becomes extremely efficient at burning fat for energy. It also converts fat into ketones in the liver, which can provide energy to the brain.
The ketogenic diet can significantly reduce blood sugar and insulin levels. This, along with increased ketone content, provides several health benefits.
Conclusion:
The keto diet is a low-carb, high-fat diet. It reduces blood sugar and insulin levels and shifts the body's metabolism from carbohydrates to fats and ketones.
Different types of ketogenic diets
There are several variations of the ketogenic diet, including:
- Standard keto diet. This is a very low carbohydrate, moderate protein, high fat diet. It typically contains 70% fat, 20% protein and only 10% carbohydrates.
- Cyclical ketogenic diet. This diet includes high-carbohydrate refeeding periods, such as 5 ketogenic days followed by 2 high-carb days.
- The ketogenic diet is targeted. This diet allows you to replenish carbohydrates during training.
- High-protein ketogenic diet. It is similar to the standard ketogenic diet but contains more protein. The ratio is usually 60% fat, 35% protein and 5% carbohydrates.
However, only the standard ketogenic diet and the high-protein ketogenic diet have been thoroughly researched. The ketogenic diet or targeted cycling are more advanced methods, mainly used by bodybuilders or athletes.
The information in this article mainly applies to the standard ketogenic diet, although many of the same principles apply to other versions as well.
Conclusion:
There are several variations of the keto diet. The standard version is the most researched and most recommended.
What is ketosis?
Ketosis is a metabolic state in which your body uses fat as an energy source instead of carbohydrates.
This happens when you significantly reduce your carbohydrate intake by limiting your body's supply of glucose (sugar), which is the main source of energy for cells.
Following a ketogenic diet is the most effective way to enter a state of ketosis. In general, to achieve ketosis, you need to limit your carbohydrate intake to about 20-50 grams per day and include fatty foods such as meat, fish, eggs, nuts and healthy oils in your diet. your drink.
It's also important to reduce your protein intake. This is because protein can be converted to glucose when consumed in large amounts, which can slow your transition to ketosis.
Practicing intermittent fasting can also help you reach ketosis faster. There are many different forms of intermittent fasting, but the most common method is to limit food intake to about eight hours a day and fast for the remaining 16 hours.
To determine whether you have entered a state of ketosis, you can use special blood, urine, and breath tests to measure the amount of ketones your body produces.
Some symptoms that may also indicate you have entered a state of ketosis include increased thirst, dry mouth, frequent urination, and decreased hunger or appetite.
Conclusion:
Ketosis is a metabolic state in which your body uses fat as an energy source instead of carbohydrates. Changing your diet and intermittent fasting can help you get into ketosis faster. Certain tests and symptoms can also help determine whether you have entered a state of ketosis.
The ketogenic diet can help you lose weight
The ketogenic diet is an effective way to lose weight and reduce disease risk factors.
In fact, research shows that a ketogenic diet may be as effective for weight loss as a low-fat diet.
Furthermore, this diet makes it possible to lose weight without counting calories or tracking your food intake.
A review of 13 studies found that very low-carb ketogenic diets were slightly more effective for long-term weight loss than low-fat diets. People following the keto diet lost an average of 0. 9 kg more than the low-fat group.
Furthermore, it also leads to a decrease in diastolic blood pressure and triglyceride levels.
Another study of 34 older adults found that those who followed a ketogenic diet for eight weeks lost nearly five times as much total fat as those who followed a low-fat diet.
Increased ketone levels, decreased blood sugar levels, and increased insulin sensitivity may also play an important role.
Conclusion:
A ketogenic diet may help you lose a little more weight than a low-fat diet. This will make you feel fuller throughout the day.
Ketogenic diet for diabetes and prediabetes
Diabetes mellitus is characterized by metabolic changes, high blood sugar levels, and impaired insulin function.
The ketogenic diet can help you lose excess fat, which is closely linked to type 2 diabetes, prediabetes and metabolic syndrome.
An earlier study found that the ketogenic diet improved insulin sensitivity by 75%.
A small study of women with type 2 diabetes also found that following a ketogenic diet for 90 days significantly reduced hemoglobin A1C levels, which is a measure of long-term blood sugar control.
Another study of 349 people with type 2 diabetes found that those following a ketogenic diet lost an average of 11. 9 kg over a 2-year period. This is an important advantage when considering the relationship between body weight and type 2 diabetes.
Furthermore, they also found that blood sugar control improved and the use of certain blood sugar-lowering medications decreased in participants throughout the study.
Conclusion:
The ketogenic diet may improve insulin sensitivity and fat loss, providing significant health benefits for people with type 2 diabetes or prediabetes.
Other benefits of the ketogenic diet
The ketogenic diet actually originated as a tool to treat neurological diseases such as epilepsy.
Studies have shown that the diet is beneficial for many diseases:
- Heart disease. The ketogenic diet may help improve risk factors such as body fat, HDL (good) cholesterol, blood pressure and blood sugar.
- Cancer. The diet is now being considered as a complementary treatment for cancer because it may help slow tumor growth.
- Alzheimer. The keto diet may help reduce symptoms of Alzheimer's disease and slow the progression of the disease.
- epilepsy. Research has shown that the ketogenic diet can significantly reduce seizures in children with epilepsy.
- Parkinson disease. Although more research is needed, one study found that the diet helps reduce symptoms of Parkinson's disease.
- Polycystic ovary syndrome. The ketogenic diet can help reduce insulin levels, which may play a key role in PCOS.
- Brain damaged. Some studies show that diet can improve outcomes in traumatic brain injury.
However, keep in mind that research in many of these areas is far from conclusive.
Conclusion:
The ketogenic diet may provide many health benefits, especially for metabolic, neurological, or insulin-related diseases.

Side effects and how to minimize them
Although the ketogenic diet is generally safe for most healthy people, there may be some initial side effects while your body adjusts.
There is some anecdotal evidence of these effects, commonly known as the keto flu.
Based on some people's reports on the meal plan, it usually ends within a few days.
The most common symptoms of keto flu are diarrhea, constipation, and vomiting.
Other less common symptoms include:
- low energy levels and poor mental function
- headache
- increased hunger
- sleep problems
- nausea
- discomfort from the digestive tract
- reduced performance
To minimize this, you can try a regular low-carb diet for the first few weeks. This can teach your body to burn more fat before you completely cut out carbs.
The ketogenic diet can also change the water and mineral balance in your body, so adding salt to your food or taking a mineral supplement may be helpful. Talk to your doctor about your nutritional needs.
When starting the keto diet, it's important to eat until you're full and not restrict your calorie intake too much. Typically, the ketogenic diet helps with weight loss without intentionally restricting calories.
Conclusion:
Many side effects when starting a ketogenic diet can be limited. Before starting the keto diet, try following a regular low-carb diet and mineral supplements for the first few weeks.
Risks of the keto diet
Long-term adherence to the ketogenic diet may have a number of negative effects, including the following risks:
- low blood protein levels
- excess fat in the liver
- kidney stones
- lack of micronutrients
A type of medicine called sodium-glucose cotransporter 2 (SGLT2) inhibitor for type 2 diabetes may increase your risk of diabetic ketoacidosis, a dangerous condition that increases blood acidity. Anyone taking this medication should avoid the keto diet.
Many studies are currently being conducted to determine the long-term safety of the keto diet. Tell your doctor about your diet plan so he or she can make informed choices.
Conclusion:
The keto diet has some side effects that you should talk to your doctor about if you plan to stay on this diet for a long time.
Dietary supplements for the ketogenic diet
Although supplements are not needed, some may be helpful.
- MCT oil. MCT oil added to drinks or yogurt provides energy and helps increase ketone levels.
- Mineral. Absorption of salt and other minerals may be important from the start due to changes in water and mineral balance.
- Caffeine. Caffeine is beneficial for increasing energy levels, productivity, and fat loss.
- Exogenous ketones. This supplement can help increase ketone levels in the body.
- Creatine. Creatine offers many health and performance-enhancing benefits. It may help if you combine a ketogenic diet with exercise.
- Whey Protein. Add half a scoop of whey protein to smoothies or yogurt to increase your daily protein intake.
Conclusion:
Some supplements may be helpful on a ketogenic diet. These include exogenous ketones, MCT oils, and minerals.
Frequently asked questions
Here are answers to some of the most common questions about the ketogenic diet.
- Can I eat carbs anymore?
Correct. However, initially it is important to significantly reduce your carbohydrate intake. After the first 2-3 months, you can eat carbohydrates on special occasions - just return to the diet immediately.
- Will I lose muscle?
With any diet there is a risk of losing muscle mass. However, high protein and ketone intake can help minimize muscle loss, especially if you lift weights.
- Can I build muscle on a ketogenic diet?
Yes, but it may not be as effective as a moderate carb diet.
- How much protein can I eat?
Protein intake should be moderate, as very high intakes can cause insulin levels to spike and ketone levels to drop. The upper limit is probably about 35% of total calories consumed.
- What should I do if I constantly feel tired, weak or tired?
You may not be in full ketosis or using fats and ketones effectively. To combat this, reduce your carbohydrate intake and go back to the points above. Supplements such as MCT oil or ketones may also be helpful.
- My urine smells fruity. What is this connected to?
Don't panic. This is simply due to the release of byproducts created during ketosis.
- My breath smells strange. What can I do?
This is a common side effect. Try drinking naturally flavored water or chewing sugar-free gum.
- I heard ketosis is extremely dangerous. Is this right?
People often confuse ketosis with ketoacidosis. Ketoacidosis is dangerous, but ketoacidosis on a ketogenic diet is usually suitable for healthy people. Talk to your doctor before starting a new diet.
- I have digestive problems and diarrhea. What can I do?
This common side effect usually goes away within 3 to 4 weeks. If the problem persists, try eating more vegetables that are high in fiber.
Summary
The ketogenic diet is good for people who:
- overweight
- diabetes
- want to improve their metabolic health
It may be less suitable for professional athletes or those looking to increase muscle mass or gain weight.
It may also not suit some people's lifestyles and preferences. Talk to your doctor about your eating plan and goals to decide if a ketogenic diet plan is right for you.
