The philosophy behind the ketogenic diet emphasizes a high-fat, low-carbohydrate intake to induce ketosis, a metabolic state where the body burns fat for fuel instead of carbohydrates. This approach aims to utilize fat stores for energy, resulting in weight loss and enhanced mental clarity for some. The diet involves keeping carbohydrate intake significantly below typical levels, forcing the body to adapt to using fats. Proponents believe that this can lead to improved metabolic function and reduced cravings, promoting healthier eating habits.
