The ketogenic diet is considered very effective in terms of results but is absolutely not without contraindications.
The ketogenic diet is a diet that significantly reduces carbohydrate intake and increases fat intakebringing the body to a metabolic state called ketosis.
In this state, the body primarily burns fat for energy, producing ketones used as an alternative energy source for the brain and other tissues. This regime limits the5-10% carbohydrate intake of daily calories, with proteins around 15-30% and fats making up the remaining 60-75%.
When you follow this diet, your body adapts to using fat as its main source of energy, producing ketones that replace glucose as fuel for the brain. This transition can cause temporary side effects known as the “keto flu,” such as fatigue, dizziness, nausea, and irritability.
The ketogenic diet is used to lose weight, improve metabolic health and increase energyand can be used as a complementary therapy for conditions such as refractory epilepsy, type 2 diabetes, Alzheimer’s disease and cancer.
The foods of the ketogenic diet
Allowed foods include healthy fats such as avocado, olive oil, nuts and seeds, lean proteins such as meat, fish and eggs, and vegetables low in carbohydrates such as spinach, kale and zucchini.
