How to Plan Weekly Meals with AI (Step-by-Step)
Let’s walk through how you can go from “What should I eat this week?” to a full 7-day plan in under 15 minutes using AI.
Step 1: Choose Your Tool (We’ll use ChatGPT or Gemini)
Go to ChatGPT or Google Gemini and use a prompt like this:
Prompt:
“Create a healthy 7-day meal plan for a vegetarian family of 4. Each day should include breakfast, lunch, and dinner. Focus on high-protein meals and avoid soy.”
Pro Tip:
Adjust the prompt based on your goals: low-carb, muscle gain, budget meals, gluten-free, etc.
Step 2: Review and Edit Meals
AI will give you a daily breakdown. You can ask it to:
-
Replace ingredients
-
Add portion sizes
-
Show prep time or calories
Example follow-up:
“Replace tofu with chickpeas in all meals.”
“Add calorie counts to each meal.”
Step 3: Generate a Grocery List
Next prompt:
“Create a categorized grocery list for this 7-day meal plan.”
AI will organize the list into produce, pantry, dairy, frozen, etc. You can copy-paste this list into your grocery app (e.g., Instacart, Amazon Fresh).
Step 4: Schedule in Whisk or Mealify
Want automation? Paste the plan into Whisk or Mealify. These apps let you:
-
Save the meal calendar
-
Auto-generate grocery lists
-
Connect to shopping apps
Now you’ve got your meals and shopping list synced — no pen, no planning, no stress.

Or use Eat This Much, which factors in calories, budget, macros, and more.
