[PASTE MEAL PLAN HERE]
Output Rules:
1. Consolidate quantities (e.g., if Day 1 needs 1 onion and Day 3 needs 2 onions, list "3 onions").
2. Organize items by standard grocery store sections (Produce, Proteins, Dairy/Alternatives, Pantry, Frozen).
3. Flag any pantry staples that the client should check for before buying (e.g., Olive Oil, Spices).
The Payoff: Removes the logistical friction for clients, making it significantly more likely they will actually buy the food and stick to the plan.
5. Clinical Concept Simplifier (Analogy Generator)
Task: Explaining complex metabolic processes to clients in non-medical language.
Best for: Claude (Renowned for natural, human-like tone and clear explanations).
Explain the concept of [CONCEPT, e.g., Insulin Resistance/Leaky Gut/Gluconeogenesis] to a client who has no medical background.
Tone: Empathetic, encouraging, and clear.
Requirement: Use a relatable real-world analogy (like a traffic jam, a lock and key, or a garden) to illustrate the mechanism. Avoid heavy jargon.
The Payoff: Improves patient literacy and trust, ensuring they understand the “why” behind their dietary interventions.
6. Drug-Nutrient Interaction Checker
Task: Quickly flagging potential conflicts between a prescribed diet and a client’s medication list.
Best for: DeepSeek or Gemini (High reliability for factual retrieval and safety checks).
Check for potential drug-nutrient interactions between the following medications and foods/supplements.
Medications: [LIST MEDS, e.g., Warfarin, Lisinopril]
Dietary Focus: [LIST DIET, e.g., High Vitamin K intake, Potassium supplements]
Output:
- Identify high-risk interactions.
- Explain the mechanism of interaction.
- Recommend dietary timing adjustments or exclusions if necessary.
*(Note: I will verify all outputs against clinical handbooks; this is for preliminary screening only.)*
The Payoff: Acts as a safety net during the planning phase, ensuring dietary recommendations do not contraindicate medical treatments.
7. The “Leftover Logic” Efficiency Planner
Task: Optimizing food waste and budget by chaining meals together.
Best for: ChatGPT (Good at logical sequencing and creative usage of inputs).
Design a 3-day meal sequence focused on zero food waste and budget efficiency for a family of 4.
Core Ingredient: [INGREDIENT, e.g., Rotisserie Chicken or 5lbs Ground Beef]
Plan:

3. Standard Dosing Protocols used in studies.
4. Any notable side effects or contraindications.
The Payoff: Allows practitioners to rapidly refresh their knowledge base and provide evidence-based answers to client queries.
Pro-Tip: Context Injection
To get the highest quality output from any of these models, use “Context Injection” at the start of your session. Before asking for a meal plan, upload or paste a “Style Guide” block that defines your philosophy.
Example: “I am a Dietitian who believes in intuitive eating, high protein, and minimal processed foods. Never recommend 1200 calorie diets. Always prioritize whole food sources over powders.”
By setting these ground rules once, every subsequent prompt in that chat session will align perfectly with your clinical brand.
Long-term success in AI-assisted nutrition doesn’t come from replacing your expertise, but from automating the administrative and computational heavy lifting so you can focus on the human element of care.
