Keto Diet Fundamentals and Core Concepts 2

Question 1

What is the primary fuel source the brain uses during nutritional ketosis?

Accepted Answer

Ketone bodies

Answer

During ketosis, the liver converts fatty acids into ketone bodies (acetoacetate, beta-hydroxybutyrate, acetone), which the brain uses as its primary fuel.

Question 2

Which of the following correctly describes the standard macronutrient ratio for a classic ketogenic diet?

Accepted Answer

70-75% fat, 20-25% protein, 5% carbs

Answer

A classic ketogenic diet is typically composed of approximately 70-75% calories from fat, 20-25% from protein, and only about 5% from carbohydrates.

Question 3

What metabolic state must the body enter for ketone production to significantly increase?

Accepted Answer

Ketosis

Answer

Ketosis is the metabolic state in which the liver produces ketone bodies at elevated levels due to low carbohydrate availability and increased fat oxidation.

Question 4

Approximately how many grams of net carbs per day does most keto guidance recommend staying under?

Accepted Answer

20-30g

Answer

Most ketogenic diet guidelines recommend limiting net carbohydrates to 20-30 grams per day to reliably induce and maintain ketosis.

Question 5

Which organ is primarily responsible for producing ketone bodies?

Accepted Answer

Liver

Answer

The liver is the primary site of ketogenesis, converting fatty acids into acetoacetate, beta-hydroxybutyrate, and acetone during periods of low carbohydrate intake.
