The ketogenic diet primarily focuses on eating more foods rich in healthy fats and good protein, while keeping carbohydrate meals to a minimum. The goal is to stimulate energy production from fat rather than carbohydrates through a process called ketosis. Studies have shown that the ketogenic diet has certain health benefits. Among the important nutrients that ketogenic dieters must supplement in their weight loss plan are calcium, magnesium, iron, vitamin D and fiber. But at the same time we also need to pay attention to some serious symptoms and side effects.
