Keto Diet Professional Practice 3 — Questions and Answers
Question 1: A client's LDL cholesterol rises significantly after 3 months on a ketogenic diet. What is the most professionally responsible course of action?
- Tell the client LDL doesn't matter on keto
- Recommend discontinuing all fats
- Review the quality of fats consumed and refer to the client's physician for further evaluation (Correct answer)
- Increase carbohydrate intake to 100g/day immediately
Correct answer: Review the quality of fats consumed and refer to the client's physician for further evaluation
Elevated LDL warrants investigating fat quality (saturated vs. unsaturated) and involving the client's physician to assess cardiovascular risk.
Question 2: When setting macronutrient targets for a keto client, which fat-to-protein ratio best maintains nutritional ketosis for most adults?
- 1:1 fat to protein by grams
- 4:1 fat to protein by weight (classic therapeutic ratio) (Correct answer)
- Equal calories from fat, protein, and carbohydrates
- 2:1 carbohydrate to fat by grams
Correct answer: 4:1 fat to protein by weight (classic therapeutic ratio)
The classic therapeutic ketogenic ratio is 4:1 (fat to combined protein and carbohydrate by weight), used especially in clinical epilepsy management.
Question 3: A keto professional is working with a pregnant client who insists on staying in ketosis. What is the best professional stance?
- Support strict ketosis throughout pregnancy without concern
- Strongly advise against strict ketogenic dieting during pregnancy and refer to an OB-GYN and perinatal dietitian (Correct answer)
- Recommend a 2:1 therapeutic ratio for the duration of pregnancy
- Advise the client to track ketones daily and adjust based on readings
Correct answer: Strongly advise against strict ketogenic dieting during pregnancy and refer to an OB-GYN and perinatal dietitian
Strict ketogenic diets are generally contraindicated during pregnancy due to risks of nutrient deficiencies and fetal development concerns.
Question 4: Which of the following best describes 'dietary ketosis' vs. 'diabetic ketoacidosis' (DKA) in professional communication with clients?
- They are the same condition with different names
- Dietary ketosis has mildly elevated ketones with normal blood glucose and pH; DKA involves dangerously high ketones, high glucose, and acidic blood pH (Correct answer)
- DKA is safe for non-diabetics on keto diets
- Dietary ketosis always leads to DKA if sustained long-term
Correct answer: Dietary ketosis has mildly elevated ketones with normal blood glucose and pH; DKA involves dangerously high ketones, high glucose, and acidic blood pH
Nutritional ketosis involves ketone levels of 0.5–3 mmol/L with normal glucose, while DKA involves ketones above 10 mmol/L with hyperglycemia and metabolic acidosis.
Question 5: A nutrition professional notices a client's food diary shows very low fiber intake on a keto diet. Which professional recommendation is most appropriate?
- Advise the client to quit the keto diet due to fiber concerns
- Encourage low-carb, high-fiber vegetables such as leafy greens, broccoli, and avocado to improve gut health (Correct answer)
- Suggest a high-dose fiber supplement without reviewing diet quality
- Tell the client fiber is unnecessary on a keto diet
Correct answer: Encourage low-carb, high-fiber vegetables such as leafy greens, broccoli, and avocado to improve gut health
Low-carb vegetables like leafy greens, broccoli, and avocado provide fiber within keto macros and support gut microbiome health.
Question 6: In professional keto counseling, what does the term 'net carbs' mean and why does it matter?
- Total carbohydrates minus fat grams
- Total carbohydrates minus fiber and sugar alcohols, representing carbs that impact blood glucose (Correct answer)
- Carbohydrates consumed only from whole grains
- Carbohydrates eaten after 6 PM
Correct answer: Total carbohydrates minus fiber and sugar alcohols, representing carbs that impact blood glucose
Net carbs are calculated by subtracting fiber and sugar alcohols from total carbs, as these minimally affect blood sugar and insulin response.
Question 7: A keto client asks about using MCT oil to enhance ketone production. Which professional response is most accurate?
- MCT oil has no effect on ketone levels
- MCT oil is rapidly converted to ketones in the liver and can enhance ketosis, but should be introduced gradually to avoid GI distress (Correct answer)
- MCT oil should only be used by athletes
- MCT oil raises blood ketones to DKA levels in healthy individuals
Correct answer: MCT oil is rapidly converted to ketones in the liver and can enhance ketosis, but should be introduced gradually to avoid GI distress
MCT oil is efficiently metabolized into ketones and can support ketosis, but starting with small doses (1 tsp) prevents common side effects like nausea and diarrhea.
