CLS Lifestyle Modification & Nutrition Counseling 2 — Questions and Answers
Question 1: A patient with hypertriglyceridemia asks about alcohol consumption. What is the most appropriate recommendation?
- Limit to 1 drink/day for women and 2 drinks/day for men (Correct answer)
- Complete abstinence from alcohol is required
- Red wine is acceptable because it raises HDL
- Alcohol has no meaningful impact on triglyceride levels
Correct answer: Limit to 1 drink/day for women and 2 drinks/day for men
Moderate alcohol limits are advised for hypertriglyceridemia, but severe cases may require complete abstinence as alcohol markedly raises triglycerides.
Question 2: Which cooking oil substitution best supports LDL reduction in a patient following a heart-healthy diet?
- Replacing butter with coconut oil
- Replacing butter with olive oil (Correct answer)
- Replacing olive oil with palm oil
- Replacing canola oil with lard
Correct answer: Replacing butter with olive oil
Replacing saturated fats (butter) with monounsaturated fats (olive oil) reduces LDL-C without adversely affecting HDL-C.
Question 3: A patient on a Mediterranean diet reports eating 5 servings of fruits and vegetables daily. Which additional dietary change would most significantly further reduce cardiovascular risk?
- Increasing red meat to 5 servings per week
- Adding 2 tablespoons of ground flaxseed daily (Correct answer)
- Switching from whole grains to refined grains
- Adding full-fat dairy to each meal
Correct answer: Adding 2 tablespoons of ground flaxseed daily
Ground flaxseed provides alpha-linolenic acid (ALA) and soluble fiber, both of which contribute to LDL reduction and cardiovascular risk improvement.
Question 4: What is the recommended aerobic exercise target per week for cardiovascular risk reduction in most adults according to major guidelines?
- 75 minutes of vigorous-intensity or 150 minutes of moderate-intensity activity (Correct answer)
- 30 minutes of light stretching on most days
- 20 minutes of vigorous activity 2 days per week
- 60 minutes of moderate activity on weekends only
Correct answer: 75 minutes of vigorous-intensity or 150 minutes of moderate-intensity activity
Current guidelines recommend at least 150 minutes/week of moderate-intensity or 75 minutes/week of vigorous-intensity aerobic activity for cardiovascular risk reduction.
Question 5: A 52-year-old patient with metabolic syndrome is counseled on weight loss. Which statement about weight loss and lipids is most accurate?
- A 5-10% weight loss can significantly improve triglycerides and HDL (Correct answer)
- Weight loss has no effect on HDL-C levels
- Only weight loss greater than 20% improves lipid parameters
- Weight loss primarily lowers LDL-C and has minimal effect on triglycerides
Correct answer: A 5-10% weight loss can significantly improve triglycerides and HDL
Even modest weight loss of 5-10% of body weight produces clinically meaningful improvements in triglycerides, HDL-C, and non-HDL-C in patients with metabolic syndrome.
Question 6: Which dietary pattern is most strongly associated with reduced non-HDL cholesterol and cardiovascular events in clinical trials?
- High-protein, low-carbohydrate (Atkins) diet
- Mediterranean diet rich in olive oil, fish, and vegetables (Correct answer)
- Low-fat, high-refined-carbohydrate diet
- Carnivore diet emphasizing animal proteins
Correct answer: Mediterranean diet rich in olive oil, fish, and vegetables
The Mediterranean diet has the strongest evidence base from randomized trials (e.g., PREDIMED) demonstrating reduced cardiovascular events and improved lipid profiles.
Question 7: A patient asks whether eating eggs will worsen their LDL cholesterol. What is the most evidence-based response?
- Eggs dramatically raise LDL in all individuals and should be eliminated
- Dietary cholesterol from eggs has modest LDL effects in most people; saturated fat intake matters more (Correct answer)
- Eggs lower LDL because they contain lecithin
- Up to 10 eggs per day is safe for all patients with dyslipidemia
Correct answer: Dietary cholesterol from eggs has modest LDL effects in most people; saturated fat intake matters more
Most individuals are dietary cholesterol non-hyper-responders; the saturated fat content of the overall diet has a larger impact on LDL-C than egg intake alone.
