The keto diet is a low-carbohydrate, high-fat eating plan designed to shift the body's metabolism from burning carbohydrates to burning fats. By significantly reducing carbohydrate intake and replacing it with fat, the body enters a state called ketosis, where it becomes more efficient at burning fat for energy. Typically, the keto diet consists of foods like meat, fish, eggs, dairy, nuts, seeds, and low-carb vegetables. It limits foods high in carbohydrates, such as bread, pasta, and sugary snacks. Many people follow this diet for weight loss, improved energy levels, and better mental clarity.
