The ketogenic diet (keto diet, low-carbohydrate high-fat (LCHF), ketogenic diet) is a low-carbohydrate diet with a moderate protein and high fat content.Classically used for epilepsy in children, dietary interpretations are recommended to combat many other diseases.But mostly nowadays it is used as a diet for weight loss.
The diet was developed in the 1920s and was successfully used to treat epilepsy, but with the popularization of anticonvulsants, the diet's relevance declined.A renewed interest in dieting dates back to the 1990s.Thanks to Hollywood producer Jim Abrahams, whose son successfully treated epilepsy with the help of the keto diet.
We present to you a complete guide to the keto diet, a list of allowed and prohibited foods and a menu for 7 days.
The essence of the ketogenic diet

The suggested diet forces the body to use fat as its main source of energy.As a rule, this function is performed by carbohydrates supplied by food: they are processed into glucose, which is "fuel" for the body, in the process of glycolysis.Fats, on the other hand, are stored in reserve.
If the diet is low in carbohydrates, the liver converts fat (from body stores or food) into fatty acids and ketone bodies: the latter enter the brain and are used as an alternative source of energy, replacing glucose.A condition in which the level of ketone bodies in the blood increases is called ketosis.
The human body adapts to the diet: during carbohydrate deficiency, it begins to use ketones instead of glucose, the optimal level of which has a number of positive effects on health, physical and mental characteristics, and also leads to a reduction in epileptic seizures.
The use of a diet for children with epilepsy involves the intake of proteins necessary for the growth and regeneration of the body and a sufficient number of calories, which is required to maintain a normal weight, taking into account the age of the particular child.
What diseases is the ketogenic diet used for?
Epilepsy
The effectiveness of the ketogenic diet in children is proven in more than half of the cases.In 2008, a randomized clinical trial confirmed the positive effect of the ketogenic diet in severe forms of epilepsy: dynamics were noted in more than 90% of cases within 6-24 months.Adherence to the diet reduces the drug load on the body, which is extremely important for such children.
A milder version of the modified Atkins diet is used for epilepsy in adult patients.
Oncological diseases
Some types of cancer cells cannot use ketones efficiently.Along with low blood sugar and growth factors, the ketogenic diet can be used for adjunctive metabolic therapy.The most promising treatment for glioblastoma.
Metabolic diseases
The diet improves insulin sensitivity (by 75% according to some data), lowers blood glucose, and normalizes the lipid profile in metabolic syndrome and type 2 diabetes.The diet naturally lowers blood sugar, so it is recommended for both type 2 diabetes patients and people with prediabetes.
Obesity
This refers to metabolic disorders, but we will write about it separately.Using fat as an energy source leads to weight loss.The ketogenic diet is effective for weight loss and helps not only to lose weight, but also to maintain the result.Some sources report a loss of 2.5-3 kg per week.
The neuroprotective effect of the diet is considered for the treatment of serious neurological diseases: Alzheimer's disease, autism, multiple sclerosis, amyotrophic lateral sclerosis, Parkinson's disease and others.Research in this field continues.
Positive effects of the keto diet
Improved cognitive function
Ketones are an excellent source of fuel for the brain.By reducing carbohydrates in the diet, the significant increase in blood sugar that occurs after a meal is eliminated.Together, this improves focus and concentration.
Increased energy and physical strength
People following a ketogenic diet have more energy throughout the day.A feeling of fullness is created for a long time after eating.The diet is used by athletes who engage in cycle sports (triathlon, cycling).Burning fat as an energy source helps preserve glycogen stores during high-intensity exercise.
- Decreased blood pressure.Losing weight leads to normal blood pressure.
- Slowing down of vascular aging.An increase in the level of beta-hydroxybutyric acid in the blood slows down the aging process of blood vessels.
- Improvement of skin condition.A low carb diet helps to get rid of acne.
The ketogenic diet also has its downsides
- Hypovitaminosis, imbalance of electrolytes and minerals.The ketogenic diet is not balanced in terms of vitamins and minerals.It may be necessary to take additional vitamin and mineral complexes.
- Increased cholesterol levels.Polyunsaturated fats raise cholesterol levels.This indicator, as well as the ratio of LDL and HDL, should be monitored.
- Decreased blood acidity.This is the result of an increase in the number of ketone bodies.For people with diabetes, this condition is fraught with intoxication of the body, diabetic coma and even death.
- Acceleration of bowel emptying time.This is a common side effect that gradually disappears: the body adapts to the new diet.
- "keto flu".A syndrome that develops in the first days of the diet and is manifested by hunger, weakness, lack of consciousness, sleep disorders, headaches and decreased physical and mental performance.These days it is recommended to drink more water and eat healthy fats.
- bad smellA side effect that can be treated with regular chewing gum or breath fresheners.You should also increase the amount of water in your diet.
- Ketoacidosis.A terrible complication of the diet, in which there is vomiting and nausea, rapid heartbeat, shortness of breath and constant thirst.If any symptoms develop, you should immediately consult a doctor.
Basic rules of the ketogenic diet
Consider the ketogenic diet in its classical sense.Currently, there are many types and variations of the keto diet (targeted, cyclical, targeted, high protein), but it is the standard diet that is the most studied and predictable.
Food is a physiological necessity of the body, a building material and a source of energy.The creators of the diet focus on this: the diet does not require a sharp restriction of food intake, a strict calorie count, and you do not need to starve.But there are also mandatory rules that cannot be deviated from.
Eat only when you are hungry, but without overeating
It is recommended to eat slowly and in a quiet environment.One portion is about 180 g.Eating is prohibited.
Ratio B:F:U – 20:65-75:10-5 (%)
This is the standard ketogenic diet (SKD).The basis of the diet is food rich in animal fats.You should think about your diet according to the presented proportions.
- Carbohydrates: 0.3 g.1 kg of weight.
- Proteins: 1.5-2 g.1 kg of weight.
- Fats - 1.8 g.1 kg of weight.
Start without preparation
The diet can be started any day and does not require a gradual reduction of carbohydrates in the diet.
Increased drinking regime
Drinking pure water is more than the physiological norm to prevent dehydration (2-3 l).
physical activity
Sports, light running, walking are needed.
The state of ketosis develops 7-14 days after the start of the diet and is manifested by a lack of hunger, the smell of acetone in sweat and urine, a specific smell from the mouth and mucous membranes, frequent urination.
