Verified step by step guidance

1. Step 1: Understand the concept of a fad diet by focusing on its key characteristics: popularity, short-term nature, promises of quick results, and lack of strong scientific support.
2. Step 2: Compare the given descriptions by identifying which one highlights these characteristics—specifically, a diet that is popular for a short time and promises rapid outcomes without solid scientific backing.
3. Step 3: Recognize that a balanced eating pattern based on national dietary guidelines emphasizes variety, adequacy, and moderation, which contrasts with the nature of fad diets.
4. Step 4: Note that a long-term eating pattern supported by multiple high-quality studies indicates a well-researched and sustainable approach, unlike fad diets.
5. Step 5: Understand that a medically supervised nutrition therapy plan is tailored for specific health conditions and is evidence-based, differing fundamentally from fad diets.
