The ketogenic diet is a strict, almost radical form of low carb - it relies on healthy fats, animal and vegetable protein and only a very small proportion of carbohydrates. In order to eat healthier and lose body fat more easily, many people and especially athletes almost completely avoid carbohydrates. The carbohydrate-reduced diet has several advantages - it reduces the feeling of hunger and the need for sleep, helps to relieve the digestive tract and increases performance. The ketogenic diet also has a positive influence on the symptoms of some diseases - including metabolic diseases, autoimmune diseases such as asthma or allergies and cancer. The explanation: Tumor cells need sugar to survive and grow quickly.
A carbohydrate-free diet sends the brain a signal about a supply shortage. At the same time, the metabolism begins with ketosis. It works like this: glucose, which is normally produced from carbohydrates, can be obtained by the brain from body fat instead of sugar. For this purpose, so-called ketogenesis takes place in the liver, whereby the body's own fat is converted into a type of sugar substitute. Only when this has already been used up does the liver resort to dietary fat. The result: The fat deposits begin to melt. The ketogenic diet is suitable for people who want to eat quickly andlose weight sustainablywant – overweight people, athletes, bodybuilders, etc.
The ketogenic diet has long been widely used in Western countries. Here is a short list of interesting books that explain the principles of the keto diet:
- Lyle McDonald – “The Ketogenic Diet”
- Dawn Marie Martenz, Laura Cramp – “The Keto Cookbook”
- Michelle Hogan – “Keto in 28”
In order for the liver to begin using fatty acids into so-called ketones for energy, the following conditions must be observed:
- Increase fat intake. The body will use the fat as fuel.
- Reduce the amount of carbohydrates to 30-100 grams per day. Keep your share to 10 percent of your total daily energy intake.
- Drink plenty of water – 2-4 liters a day.
- The optimal protein intake is 1.5 – 2 g per kg of body weight.
- Eat only 2 to 3 times a day.
- Make sure you get enough physical activity – running, long walks, fitness, etc.
The transition to ketosis only occurs after 7-14 days. Its signs: lack of hunger, smell of acetone through sweat, urine and saliva, dry mouth, frequent urination.
Like any restriction, the ketogenic diet has positive and negative aspects. Let's look at the positives first.
1. Successful weight loss
The keto diet is recognized by most athletes and nutritionists. It helps to quickly get rid of the extra pounds in a very short time. The fat is metabolized in the body and turned into energy. You start burning fat and losing weight. The volume of muscle mass does not change and can even be increased with a good program. The ketogenic diet is also suitable for people who do not do active sports.
2. Permanent feeling of satiety
Since the keto diet is based on high-calorie foods, you will forget about the problem of feeling hungry. Because of the low carbohydrate intake, the insulin level, which is responsible for unwanted hunger attacks, drops. This will help you focus on important topics and not just think about food.
3. Prevention and control of diabetes
The foods allowed on the keto diet help lower blood sugar. A low-carbohydrate diet is particularly recommended for people with insulin resistance.
4. Treatment of epilepsy
This diet is used to treat epilepsy in children. The advantage for epileptics is that the keto diet can reduce the severity of the disease and the frequency of seizures.
5. The keto diet normalizes blood pressure and cholesterol levels
A diet high in carbohydrates and fat leads to a sharp increase in high-density lipoproteins (HDL) and reduces the concentration of low-density lipoproteins (LDL). Adherents of the keto diet note that it leads to normalization of blood pressure. Overweight people have an increased risk of developing high blood pressure. The ketogenic diet not only helps in losing weight but also in preventing high blood pressure problems.
6. Improves brain function
The keto diet increases brain activity. Ketones produced by the liver act as a source of energy and improve concentration and attention.
7. improves the complexion
Your lifestyle has a significant influence on the appearance of your skin. The permanent reduction in carbohydrates and dairy products has a positive effect on the skin and makes it look beautiful and radiant.
Disadvantages of the keto diet
In the phase of adapting to the high-fat diet, the so-called “keto flu” occurs. It may be accompanied by one or more symptoms: nausea, heartburn, swelling, constipation, headache, palpitations, fatigue, cramps. These symptoms appear 4-5 days after starting the diet and are not a cause for concern. To avoid the keto flu, reduce the amount of carbohydrates gradually.

Risks and side effects
Before choosing the keto diet, you should evaluate your body's fitness and health status. Here are some of the main disadvantages that should be noted:
1. Indigestion
Indigestion is one of the most common and unpleasant symptoms associated with the keto diet. Since the body is not yet used to the lack of carbohydrates, it can protest against it. This could lead to symptoms such as constipation, diarrhea, abdominal swelling or heartburn. Kefir, yogurt and leafy vegetables help here.
Strict avoidance of carbohydrates
2. Lack of microelements
To avoid disorders caused by vitamin deficiency, you should take a multivitamin complex. If necessary, also increase carbohydrates.
3. Increased cholesterol levels
The polyunsaturated fats on which the ketogenic diet is based increase cholesterol levels, which are considered a risk factor for cardiovascular disease. Control your health and monitor your cholesterol levels.
Lose weight healthily
Experts recommend…
According to nutrition experts, you should not follow the ketogenic diet for more than two months. Researcher at the University of Sydney, Dr. Alan Barkley, believes the keto diet “may be safe for health in the short and medium term.” Another expert, Dr. Alexei Alexandrovich, believes that this diet poses several health risks, but they can be avoided if you listen to your body. Possible complications of ketosis include ketoacidosis. Symptoms are vomiting, nausea, dehydration, palpitations, shortness of breath, constant thirst. If you experience any of these symptoms, you should definitely see a doctor.
What type of training will effectively help you lose weight?
Due to ketosis and low blood sugar levels, short but high-intensity workouts are best. A good example is Tae-Bo training and Pavel Tsatsouline's strength training exercises. Avoid aerobic endurance exercises as these can lead to hypoglycemia (low blood sugar). If you feel nauseous and dizzy, eat 100 grams of chocolate and stop exercising.
However, the consistent implementation of the ketogenic diet requires strict discipline. For defined muscles without fat deposits you definitely need to do it regularlyto do sports.
