Verified step by step guidance

1. Understand the goal of a ketogenic diet, which is to promote ketosis—a metabolic state where the body uses fat as its primary energy source instead of carbohydrates.
2. Recall that macronutrients include carbohydrates, proteins, and fats, each playing different roles in metabolism and energy production.
3. Recognize that in a ketogenic diet, carbohydrate intake is significantly reduced to lower blood glucose and insulin levels, which encourages the body to enter ketosis.
4. Note that dietary fat is not limited; in fact, it is increased to provide the main energy source during ketosis.
5. Protein intake is usually moderate to maintain muscle mass but is not the primary macronutrient restricted to induce ketosis.
