A ketogenic diet, often referred to as keto diet, is a low-carbohydrate, high-fat diet that has been used for various purposes, including weight loss, managing certain medical conditions, and improving overall health and well-being. The primary goal of a ketogenic diet is to shift the body’s metabolism from relying on carbohydrates as its main source of energy to using fats and ketones instead.
The typical macronutrient composition of a ketogenic diet is high in fats, moderate in protein, and very low in carbohydrates. The specific ratios may vary, but a common approach is to consume around 70-75% of calories from fat, 20-25% from protein, and only about 5-10% from carbohydrates. This drastic reduction in carbohydrate intake forces the body to enter a state called ketosis.
In ketosis, the body produces molecules called ketones from fats, which become the primary source of fuel for the body and brain, replacing glucose derived from carbohydrates. By restricting carbohydrate intake, insulin levels are lowered, and the body starts breaking down stored fat into ketones, which can be utilized for energy.
The ketogenic diet involves consuming foods that are naturally high in healthy fats, such as avocados, nuts, seeds, olive oil, coconut oil, and fatty fish. It also includes moderate amounts of protein, which can be obtained from sources like meat, poultry, fish, eggs, and dairy products. Carbohydrate-rich foods, including grains, sugars, starchy vegetables, and most fruits, are significantly limited or avoided altogether.
Benefits attributed to the ketogenic diet include weight loss, improved blood sugar control, increased energy levels, enhanced mental focus, and a potential reduction in inflammation. It has also been used therapeutically to manage conditions like epilepsy, type 2 diabetes, polycystic ovary syndrome (PCOS), and some neurological disorders. However, it’s important to note that the long-term effects and potential risks of the ketogenic diet are still being studied, and it may not be suitable for everyone. Consulting with a healthcare professional or a registered dietitian is advisable before starting any significant dietary changes.
