Keto Diet Advanced Applications 3 — Questions and Answers
Question 1: How does exogenous ketone supplementation affect endogenous ketone production?
- It increases endogenous production
- It has no effect
- It suppresses endogenous ketone production by providing an external source (Correct answer)
- It permanently raises BHB levels
Correct answer: It suppresses endogenous ketone production by providing an external source
When exogenous ketones are consumed, the body detects elevated BHB and reduces its own production via feedback mechanisms.
Question 2: Which type of dietary fat is most associated with raising LDL cholesterol on a ketogenic diet?
- Monounsaturated fats (olive oil)
- Omega-3 polyunsaturated fats
- Saturated fats (butter, coconut oil) (Correct answer)
- Medium-chain triglycerides (MCT)
Correct answer: Saturated fats (butter, coconut oil)
High intake of saturated fats, common on keto, can raise LDL-C in some individuals, particularly LDL particle count.
Question 3: What is the clinical term for the extreme state of uncontrolled ketone production primarily seen in type 1 diabetics?
- Nutritional ketosis
- Hyperketonemia
- Diabetic ketoacidosis (DKA) (Correct answer)
- Ketoadaptation
Correct answer: Diabetic ketoacidosis (DKA)
DKA involves dangerously high ketones (>10 mmol/L) combined with high blood glucose and low insulin, distinct from dietary ketosis.
Question 4: For individuals with epilepsy on the classic ketogenic diet, what macronutrient ratio is typically prescribed?
- 1:1 fat-to-protein+carb
- 2:1 fat-to-protein+carb
- 4:1 fat-to-protein+carb (Correct answer)
- 3:1 fat-to-protein+carb
Correct answer: 4:1 fat-to-protein+carb
The classic medical ketogenic diet for epilepsy uses a 4:1 ratio (grams fat to grams protein+carbs) to maximize ketone production.
Question 5: What physiological mechanism explains improved mental clarity often reported during ketosis?
- Higher blood glucose to the brain
- BHB crossing the blood-brain barrier and serving as a highly efficient neuronal fuel (Correct answer)
- Reduced sleep requirement
- Increased dopamine synthesis
Correct answer: BHB crossing the blood-brain barrier and serving as a highly efficient neuronal fuel
Beta-hydroxybutyrate crosses the blood-brain barrier and provides neurons with more ATP per unit oxygen than glucose does.
Question 6: Which dietary intervention is most effective at breaking a weight-loss plateau on a well-formulated ketogenic diet?
- Adding more dietary fat
- Implementing intermittent fasting alongside keto (Correct answer)
- Increasing carbohydrate intake to 100g/day
- Eliminating all protein
Correct answer: Implementing intermittent fasting alongside keto
Combining intermittent fasting with keto further lowers insulin, accelerates fat mobilization, and can overcome metabolic adaptation.
Question 7: In the context of keto and cardiovascular health, what is the significance of measuring ApoB rather than total LDL cholesterol?
- ApoB measures only HDL particles
- ApoB counts all atherogenic lipoprotein particles, providing a better cardiovascular risk estimate (Correct answer)
- ApoB measures triglycerides exclusively
- ApoB indicates liver health only
Correct answer: ApoB counts all atherogenic lipoprotein particles, providing a better cardiovascular risk estimate
ApoB reflects the number of atherogenic particles (LDL, VLDL, IDL) and is a stronger predictor of cardiovascular risk than calculated LDL-C.
