Claude for Nutritionists: Build a 90-Day Client Meal Plan
💡 How to use this prompt
- Start with output item 6 (the weekly check-in question set) before you finalize the meal plan itself. The questions reveal which early dropout signals your current onboarding misses — if you design the 4-week meal plan first and then build the check-in around it, you are measuring plan adherence rather than the behavioral patterns that predict whether a client will still be following the plan in week 6.
- The most common mistake is setting the calorie target in the situation field without specifying cooking skill level and weeknight time constraints alongside it. A 1,600 kcal plan built around 45-minute weeknight recipes will be abandoned by week 2 by a client with 25 minutes and basic skills — the plan fails before the nutrition has a chance to work. Fill in both fields with real specifics before running the prompt.
- Claude outperforms ChatGPT on this task because it maintains nutritional consistency across all 4 weeks of the meal plan — macro ratios, calorie targets, and swap compatibility — without drifting in the later weeks. ChatGPT tends to produce week 1 and 2 correctly then introduces inconsistent calorie counts and incompatible swaps in weeks 3 and 4. Use Claude for the full 90-day plan and ChatGPT only for quick single-meal variations.
