Q: Analyze the strengths and weaknesses of the traditional Vietnamese diet from a nutritional science perspective. How have Vietnamese dietary trends over the past decade impacted health?

Two-dimensional analysis: traditional vs. modern, positive vs. negative. Connect to Vietnamese epidemiological disease data.

Q: Compare the roles of a clinical nutritionist and a community nutritionist. Which role do you feel more suited for and why?

Present a comparison of the two roles, then self-assess your strengths and reasons for your direction. Candidates should present: (1) Clinical nutritionist: hospital environment, working with individual patients, therapeutic nutrition intervention, multidisciplinary consultation, enteral/parenteral nutrition, (2) Community nutritionist: working with population groups, nutrition education programs, disease prevention, public policy, nutritional epidemiology research, (3) In Vietnam: Community nutrition network through commune health stations, National Institute of Nutrition; upper-level hospitals need both functions, (4) Self-assessment: candidates should state their specific skills and how they match their chosen role - should not answer 'both are fine' without reasoning, (5) Trend: today's nutrition specialists need competency in both fields.

Q: How do you counsel dietary change for a patient with low motivation to change? Describe the techniques you use when a patient consistently fails to follow the agreed nutrition plan.

Apply Motivational Interviewing (MI) and Prochaska & DiClemente's Transtheoretical Model (Stages of Change). Combine with STAR. Candidates should present: (1) Assessing current stage of change (Pre-contemplation, Contemplation, Preparation, Action, Maintenance) and adjusting strategy accordingly, (2) MI core: OARS (Open questions, Affirmation, Reflective listening, Summary), avoid confrontation, develop 'change talk', (3) Exploring real barriers: finances, family culture, cooking habits, lack of knowledge, conflicting beliefs, (4) Setting SMART and realistic goals, gradual small steps (behavioral shaping), (5) Personalizing plan to Vietnamese lifestyle reality: family meals, morning street food, weddings/funerals, (6) Using food diary for self-monitoring, (7) Not blaming the patient - dietary behavior change is a long process. Bonus if they mention the Health Belief Model.

Q: A young track and field athlete (19 years old, male, training twice daily, 6 days a week) comes to you with the goal of building muscle and maintaining endurance. How do you develop a sports nutrition plan?

Apply Periodization Nutrition - adjusting nutrition according to training cycle (pre, during, post-workout) and training phase (base, build, peak, recovery).

Question 8

A patient asks you about the keto diet and intermittent fasting they saw on social media. They want to apply them for rapid weight loss. How do you respond from an evidence-based science perspective?

Accepted Answer

Use Shared Decision Making combined with evidence analysis: present scientific evidence, assess individual suitability, provide professional recommendation. Candidates should present: (1) Keto diet - evidence: effective short-term weight loss, improves triglycerides and blood glucose; limitations: difficult long-term adherence, micronutrient deficiencies (vitamin C, fiber), unclear long-term kidney function impact, unsuitable for kidney disease, pancreatitis; long-term evidence is limited, (2) Intermittent fasting (16:8, 5:2) - evidence: weight loss equivalent to continuous calorie restriction, improves insulin sensitivity; limitations: unsuitable for insulin-dependent diabetes, pregnancy, eating disorders, (3) Comparison with more sustainable weight loss diets: Mediterranean diet has more evidence for long-term health outcomes, (4) Do not completely dismiss - listen to why the patient chose it, discuss actual goals, (5) Warn about misinformation on social media and unqualified nutrition advice. Bonus if they know the evidence hierarchy (meta-analysis > RCT > observational).
