In-Depth Exploration of the Ketogenic Diet

Continuing our series on dietary trends, we turn to the insights of a seasoned doctor and dietitian. Today, we delve into the ketogenic diet*. The essence of this dietary approach lies in minimizing carbohydrate intake, which includes not only pastries, pasta, sugar, and its substitutes but also honey, fruits, root vegetables, cereals, and rice in any form. The diet allows for a carbohydrate quota of only 5%, sourced from berries, greens, and select vegetables. By contrast, the WHO-regulated standard food pyramid emphasizes carbohydrates constituting up to 60% of a balanced diet.

Concerns about health risks associated with excessive protein intake are valid, so where does one derive energy? The answer lies in fats. There is no need to fear them; the cholesterol scare tactics that dominated the 20th century are now viewed in the 21st century as propaganda by interested pharmaceutical companies. It's crucial to note: we are referring to healthy fats rich in polyunsaturated fatty acids, not juicy kebabs, margarine, or trans fats, which are detrimental to health.

The ketogenic diet boasts a robust scientific foundation, showing remarkable results in children and adults with epilepsy, often leading to the disappearance of seizure syndromes upon discontinuation of anticonvulsant medications. It has proven effective for individuals with certain autoimmune conditions, Alzheimer's disease, and even cancer. The crux lies in the fact that tumor cells "feed" on glucose, whereas research indicates that transitioning to a virtually carb-free but high-fat dietary regimen can lead to regression of the tumor process.

Observations of patients adhering to this dietary model have revealed surprising benefits: increased energy levels, enhanced brain activity, and improved mood. The focus is on biochemical processes: the body switches to new energy sources—ketones, formed during fat breakdown.

The initial proponents of the ketogenic diet were biohackers from Silicon Valley, eager to live a long and healthy life. They were soon joined by celebrities, and the obsession with the ketogenic diet quickly spread worldwide. Shedding excess fat while consuming fats—achieving this may simply require dedication.

Only an experienced physician-dietitian should prescribe the ketogenic diet. Not a diet consultant, not an Instagram food blogger, not a nutritionist, or a keto devotee. This dietary system has specific contraindications, such as diabetes, chronic pancreatitis, cholecystitis, familial hyperlipidemia, and more. Moreover, during the initial stages of the diet, when transitioning to alternative energy sources, the so-called "keto flu" is common. At this moment, a guiding doctor is needed to prescribe necessary micronutrients, alleviate ketosis side effects, and help correctly calculate the protein, fat, and carbohydrate norms.

All diets and eating regimes should be coordinated with your physician.
