Which of the following describes a ketogenic diet?

A ketogenic diet is characterized by a high intake of fats, a low intake of carbohydrates, and a moderate intake of protein. This dietary approach aims to shift the body's metabolism away from carbohydrates and towards fat as the primary source of energy through a metabolic state known as ketosis.

In this state, the body converts fats into ketone bodies, which serve as an alternative fuel. The restriction of carbohydrates is essential to initiate and maintain ketosis, which is why the diet is defined by its low carbohydrate content. The emphasis on high fat consumption provides the necessary caloric intake while still allowing adequate protein to maintain muscle mass, thus falling into the 'normal' protein category instead of high protein.

This composition differentiates a ketogenic diet from other diet types, including those that might prioritize protein or have a balanced macronutrient profile.
