Keto Diet Safety and Compliance 2 — Questions and Answers
Question 1: Which population should NEVER start a ketogenic diet without close medical supervision due to a life-threatening metabolic risk?
- Individuals with type 1 diabetes (Correct answer)
- Recreational athletes
- Healthy adults over 50
- Vegetarians
Correct answer: Individuals with type 1 diabetes
People with type 1 diabetes risk diabetic ketoacidosis (DKA) on keto and require strict medical oversight.
Question 2: A patient on lithium therapy asks about starting keto. The primary safety concern is that ketosis may:
- Increase lithium excretion and lower blood levels
- Increase lithium absorption to toxic levels (Correct answer)
- Have no interaction with lithium
- Reduce the need for lithium
Correct answer: Increase lithium absorption to toxic levels
Ketogenic diets can reduce kidney clearance of lithium, raising serum lithium to potentially toxic levels.
Question 3: Which lab marker should be monitored specifically to detect early kidney stress during long-term ketogenic dieting?
- Serum creatinine and eGFR (Correct answer)
- Fasting insulin only
- Total cholesterol
- TSH (thyroid-stimulating hormone)
Correct answer: Serum creatinine and eGFR
Creatinine and eGFR directly reflect kidney filtration function, which can be stressed by high protein intake on keto.
Question 4: How should someone with a history of kidney stones approach a ketogenic diet?
- Consult a nephrologist and increase fluid intake (Correct answer)
- Avoid the diet entirely under all circumstances
- Double calcium supplement intake
- Begin immediately but avoid all fats
Correct answer: Consult a nephrologist and increase fluid intake
Keto can raise uric acid and calcium oxalate levels, so nephrology guidance and hydration are critical for stone-prone individuals.
Question 5: Pregnant women are generally advised to avoid strict ketogenic diets because ketones:
- Cross the placenta and may impair fetal brain development (Correct answer)
- Cause excessive weight gain in the fetus
- Are filtered out by the placenta completely
- Increase folic acid absorption
Correct answer: Cross the placenta and may impair fetal brain development
Elevated ketones can cross the placental barrier and potentially disrupt fetal neurological development.
Question 6: A person taking SGLT2 inhibitors (e.g., empagliflozin) starts keto. The dangerous risk unique to this drug-diet combination is:
- Euglycemic diabetic ketoacidosis (Correct answer)
- Severe hyperglycemia
- Acute liver failure
- Hyponatremia
Correct answer: Euglycemic diabetic ketoacidosis
SGLT2 inhibitors combined with keto can trigger euglycemic DKA — dangerously high ketones with near-normal blood sugar.
Question 7: Which symptom during the first week of keto most commonly signals dangerous dehydration rather than normal 'keto flu'?
- Heart palpitations with dizziness upon standing (Correct answer)
- Mild fatigue and brain fog
- Temporary cravings for carbohydrates
- Slight headache in the morning
Correct answer: Heart palpitations with dizziness upon standing
Orthostatic palpitations and dizziness indicate significant fluid and electrolyte loss requiring prompt attention.
