Your friend seeks professional advice on a weight-loss program. Which professional would be the BEST source of nutrition guidance?

• A. Personal trainer
• B. Registered dietitian (RD)
• C. General practitioner
• D. Waiter

Answer: (B)

When you want nutrition guidance for weight loss, you need someone with formal training in food and nutrition who can tailor plans to your health needs. A registered dietitian has completed extensive education in nutrition, supervised practice, passed a national exam, and stays current with ongoing education. This background allows them to assess your medical history and medications, determine safe calorie goals, design a balanced, individualized meal plan, and adjust it as you progress. They’re equipped to ensure nutrient adequacy while reducing calories and to coordinate with other health professionals if needed.

A personal trainer focuses on exercise and may offer general diet tips, but they don’t have the specialized nutrition credentials. A general practitioner provides medical supervision and basic nutrition advice but usually refers to a dietitian for detailed meal planning. A waiter has no relevant professional nutrition credentials. For precise, personalized nutrition guidance in a weight-loss program, the best choice is the registered dietitian.
