Keto Diet Assessment and Evaluation 5 — Questions and Answers
Question 1: A keto dieter complains of persistent fatigue at week 6. Which assessment should be prioritized first?
- Electrolyte status (sodium, potassium, magnesium) and total caloric intake (Correct answer)
- Immediate reintroduction of carbohydrates
- Checking for ketone levels only
- Testing for food allergies
Correct answer: Electrolyte status (sodium, potassium, magnesium) and total caloric intake
Persistent fatigue beyond week 4 on keto is most commonly caused by electrolyte deficits or inadequate caloric intake, both of which are easily corrected.
Question 2: How does the ketogenic diet typically affect the Triglyceride-to-HDL ratio, and why is this clinically significant?
- It lowers the ratio, which is associated with reduced insulin resistance and cardiovascular risk (Correct answer)
- It raises the ratio, indicating worsening metabolic health
- It has no effect on this ratio
- It only affects the ratio in people with diabetes
Correct answer: It lowers the ratio, which is associated with reduced insulin resistance and cardiovascular risk
A Trig/HDL ratio below 2.0 is associated with insulin sensitivity and low cardiovascular risk; keto reliably improves this ratio.
Question 3: What is the significance of tracking ketone levels at different times of day rather than just once?
- Ketones fluctuate naturally; multiple readings give a more accurate picture of metabolic state (Correct answer)
- Ketones should be identical regardless of time
- Only morning readings are ever accurate
- Evening readings always overestimate ketosis
Correct answer: Ketones fluctuate naturally; multiple readings give a more accurate picture of metabolic state
Blood ketones vary with meals, exercise, and stress; tracking at multiple consistent time points reduces noise in self-assessment.
Question 4: A client's blood pressure drops from 145/90 to 118/76 after 8 weeks of keto. What is the most important follow-up action?
- Consult their physician to review antihypertensive medications, as dosing may need adjustment (Correct answer)
- Increase sodium intake to raise blood pressure back up
- Discontinue the diet as blood pressure changes are unsafe
- No action needed since lower blood pressure is always better
Correct answer: Consult their physician to review antihypertensive medications, as dosing may need adjustment
Significant blood pressure reductions can make existing antihypertensive medications cause hypotension, requiring medical review of dosages.
Question 5: Which finding on a standard metabolic panel warrants the greatest concern in a long-term keto dieter?
- Persistently elevated creatinine with declining GFR (Correct answer)
- Slightly elevated AST and ALT in the first 4 weeks
- Total protein at the lower end of normal
- Potassium at 4.2 mEq/L
Correct answer: Persistently elevated creatinine with declining GFR
Rising creatinine and declining GFR suggest kidney stress, which requires investigation as high-protein variants of keto can increase renal load.
Question 6: What does a consistently low fasting insulin level (below 5 µIU/mL) confirm about a keto dieter's metabolic progress?
- Excellent insulin sensitivity and effective suppression of insulin-driven fat storage (Correct answer)
- Risk of hypoglycemia
- Insufficient protein intake
- Liver glycogen depletion
Correct answer: Excellent insulin sensitivity and effective suppression of insulin-driven fat storage
Fasting insulin below 5 µIU/mL indicates highly sensitive insulin signaling and minimal basal insulin-driven fat storage.
Question 7: When evaluating progress after 12 weeks on a ketogenic diet, which combination of results most comprehensively confirms success?
- Reduced waist circumference, improved fasting insulin, lower triglycerides, and sustained energy levels (Correct answer)
- Weight loss alone
- High urine ketone readings throughout
- Normal total cholesterol with no other changes
Correct answer: Reduced waist circumference, improved fasting insulin, lower triglycerides, and sustained energy levels
True keto success is multidimensional — body composition, metabolic markers, lipids, and subjective well-being should all improve together.
