A ketogenic diet, often referred to as a keto diet, is a low-carbohydrate, high-fat diet that has been shown to offer various health benefits. The primary goal of the diet is to shift the body's metabolism from burning glucose (sugar) to burning ketones and fat. This metabolic state is known as ketosis. The typical macronutrient ratio in a ketogenic diet is approximately 70-75% fat, 20-25% protein, and 5-10% carbohydrates.
