Ketodiæten

Ketodiæten, often referred to as the ketogenic diet, is a very low-carbohydrate, high-fat eating plan. The primary goal of this diet is to shift the body's primary energy source from glucose, derived from carbohydrates, to ketones, which are produced from fat. This metabolic state is known as ketosis.

Typically, a ketogenic diet involves consuming a very high percentage of calories from fat, moderate protein, and very few carbohydrates. The exact macronutrient ratios can vary, but a common guideline is around 70-80% fat, 20-25% protein, and 5-10% carbohydrates. This means drastically limiting foods rich in carbohydrates such as grains, sugars, fruits, and starchy vegetables. Instead, the diet emphasizes foods like fatty meats, fish, eggs, healthy oils, nuts, seeds, and low-carbohydrate vegetables.

The body enters ketosis when carbohydrate intake is so low that the liver begins to break down fatty acids into ketone bodies. These ketones can then be used by the brain and other organs for energy. Proponents of the ketogenic diet suggest it can lead to weight loss, improved blood sugar control for individuals with type 2 diabetes, and potential therapeutic benefits for certain neurological conditions. However, it is important to note that the diet can be restrictive and may lead to side effects such as the "keto flu," which includes symptoms like fatigue, headache, and nausea, particularly in the initial stages. Consulting with a healthcare professional before starting the ketogenic diet is generally recommended.
