Ketogenic diet: menu, allowed and forbidden foods

Ketogenic diet (keto diet, Low Carb High Fat (LCHF), Ketogenic diet) is a low-carbohydrate diet with moderate protein and high fat content.Classically used for epilepsy in children, the diet is recommended to fight many other diseases.But mostly nowadays it is used as a diet for weight loss.

The diet was developed in the 1920s and was used successfully to treat epilepsy, but with the spread of anticonvulsants, the importance of the diet declined.Renewed interest in the diet dates back to the 1990s thanks to Hollywood producer Jim Abrahams, whose son was successfully treated for epilepsy with the help of the keto diet.

We present a complete guide to the keto diet, a list of allowed and forbidden foods and a menu for 7 days.

The essence of the ketogenic diet

The essence of the ketogenic diet for weight loss

A planned diet forces the body to use fat as its primary source of energy.Normally, this action is carried out by the carbohydrates that come with food: they are processed into glucose during glycolysis, which is "fuel" for the body.Fat, on the other hand, is stored in reserves.

If there is little carbohydrate in the diet, the liver converts fat (from body stores or from food) into fatty acids and ketone bodies: the latter enter the brain and are used as another source of energy, instead of glucose.A condition in which the level of ketones in the blood increases is called ketosis.

The human body adapts to the diet: when there is a lack of carbohydrates, it begins to use ketones instead of glucose, the optimal amount of which has many 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 includes the intake of the amount of protein necessary for the growth and regeneration of the body and the sufficient amount of calories needed to maintain a normal weight, taking into account the age of the particular child.

For which diseases is the ketogenic diet used?

Epilepsy

In children, the effectiveness of the ketogenic diet is confirmed in more than half of the cases.In 2008, a randomized clinical trial confirmed the positive effects of the ketogenic diet in severe forms of epilepsy: dynamics were observed in more than 90% of cases within 6-24 months.Following the diet reduces the body's drug load, which is extremely important for such children.

For epilepsy in adult patients, a lighter version is used - a modified Atkins diet.

Cancerous diseases

Some types of cancer cells cannot use ketones effectively.In combination with hypoglycemia and growth factors, a ketogenic diet can be used for adjunctive metabolic therapy.Most promising for the treatment of glioblastoma.

Metabolic diseases

The diet leads to an improvement in insulin sensitivity (according to some data, about 75%), a decrease in blood sugar and a normal lipid profile in metabolic syndrome and type 2 diabetes. The diet naturally lowers blood sugar and is therefore recommended for both patients with type 2 diabetes and people with prediabetes.

Obesity

It refers to a metabolic disease, but we will write about it separately.Using fat as an energy source leads to weight loss.Ketogenic diet is effective for weight loss and helps not only to lose weight, but also to maintain the result.Some sources say to lose about 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 area is ongoing.

The 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, there is a significant increase in blood sugar that occurs after eating out.Together, this improves focus and concentration.

Increased energy and physical strength

People following a ketogenic diet have more energy throughout the day.After eating, a feeling of fullness develops for a long time.The diet is used by athletes who do cycling sports (triathlon, cycling).Burning fat as an energy source helps preserve glycogen stores during high intensity exercise.

  • Lowered blood pressure.Weight loss leads to normal blood pressure.
  • Slowing down the aging of blood vessels.Increased levels of beta-hydroxybutyric acid in the blood slow down the aging of blood vessels.
  • Improved skin condition.A low carb diet helps get rid of acne.

The ketogenic diet also has disadvantages

  • Hypovitaminosis, electrolyte and mineral imbalance.A ketogenic diet is not balanced in vitamins and minerals.Supplemental intake of vitamin and mineral complexes may be necessary.
  • Elevated cholesterol levels.Polyunsaturated fats increase cholesterol levels.This measure should be monitored, as should the ratio of LDL to HDL.
  • Decreased blood acidity.This is a result of an increase in the number of ketone bodies.For people suffering from diabetes, the condition is full of intoxication of the body, diabetic coma and even death.
  • Speeds up bowel emptying time.This is a common side effect that disappears gradually: the body adapts to the new diet.
  • "Keto Flu".A syndrome that develops in the first days of the diet and is manifested by an increased feeling of hunger, weakness, absence, sleep disturbances, headaches and reduced physical and mental performance.It is recommended to drink more water and eat healthy fats these days.
  • Bad breath.A side effect that can be treated with regular chewing gum or inhalation.You should also increase the amount of water in your diet.
  • Ketoacidosis.A terrible complication of diet, in which vomiting and nausea, rapid heartbeat, shortness of breath and constant thirst occur.If any of the symptoms occur, you should immediately contact a doctor.

Basic principles of the ketogenic diet

Let's consider the ketogenic diet in the classical sense.Currently, there are many varieties and variations of the keto diet (targeted, cyclical, targeted, high protein) but it is the standard diet that is the most researched and predictable.

Food is the body's physiological necessity, building material and source of energy.Diet developers focus on this: the diet does not require extreme restriction of food intake, strict calorie counting, and you do not have to starve.But there are also mandatory rules that cannot be deviated from.

Eat only when you feel hungry, but without overeating

It is recommended to eat slowly and in a quiet environment.One serving is approximately 180 g.Snacks are not allowed.

Ratio B:F:U – 20:65-75:10-5 (%)

This is the standard ketogenic diet (SKD).The basis of the diet is foods rich in animal fat.You should think through your diet according to the proportions provided.

  • Carbohydrates: 0.3 g.per 1 kg of weight.
  • Protein: 1.5-2 g.per 1 kg of weight.
  • Fat - 1.8 g.per 1 kg of weight.

Start without preparation

The diet starts any day and does not require a gradual reduction of carbohydrates in the diet.

Increased drinking rule

Drinking clean water is more than the physiological norm to prevent dehydration (2-3 l).

Physical activity

Sports, light jogging, walking are essential.

A state of ketosis develops 7-14 days after starting the diet and is manifested by a lack of hunger, an acetone odor from sweat and urine, a specific odor from the mouth and dry mucous membranes, and frequent urination.
