Introduction to the Ketogenic Diet
Knowledge check
Q1. What is the primary goal of the ketogenic diet?
- A. To increase carbohydrate intake
- B. To shift the body's primary energy source from carbohydrates to fats ✓
- C. To increase protein intake
- D. To reduce water intake
Why: The ketogenic diet aims to induce a metabolic state called ketosis, where the body uses fat as its primary energy source instead of carbohydrates.
Q2. Which macronutrient is the main source of energy in a ketogenic diet?
- A. Carbohydrates
- B. Fats ✓
- C. Proteins
- D. Alcohol
Why: In a ketogenic diet, fats are the primary source of energy as the body shifts to using fat for fuel when carbohydrate intake is very low.
Q3. What is ketosis?
- A. A state where the body uses carbohydrates as the main energy source
- B. A metabolic state where the body burns fat for fuel ✓
- C. A state of high carbohydrate intake
- D. A state of high protein intake
Why: Ketosis is a metabolic state where the body burns fat for fuel, typically induced by a very low-carbohydrate, high-fat diet like the ketogenic diet.
Q4. What is the typical daily carbohydrate intake on a ketogenic diet?
- A. 100-150 grams
- B. 50-100 grams
- C. 20-50 grams
- D. Less than 20 grams ✓
Why: To achieve and maintain ketosis, most people on a ketogenic diet consume less than 20 grams of carbohydrates per day.
Q5. Which of the following is a common side effect when starting a ketogenic diet?
- A. Increased energy
- B. Weight gain
- C. Keto flu ✓
- D. Increased appetite
Why: The 'keto flu' is a common side effect when starting a ketogenic diet, often due to the body adjusting to a lower carbohydrate intake and increased fat metabolism.

- A. Less than 10% of calories
- B. 10-20% of calories ✓
- C. 20-30% of calories
- D. More than 30% of calories
Why: Protein intake on a ketogenic diet is typically moderate, around 10-20% of total daily calories, to avoid interfering with ketosis.
Q5. Which of the following is a sign that the body is in ketosis?
- A. Increased appetite
- B. Weight gain
- C. Bad breath ✓
- D. Increased energy levels
Why: Ketosis can lead to bad breath due to the presence of ketones in the body, which is a common indicator of the metabolic state.
