Quick Answer
AI can generate a full weekly meal plan — grocery list included — in under 15 minutes. Share your calorie target, dietary restrictions, and budget, and tools like ChatGPT, Eat This Much, or PlateJoy will do the rest.
- Best free plan: ChatGPT with macros in the prompt
- Best automated app: Eat This Much (~$59/yr)
- Best for tracking: MyFitnessPal Premium
What You'll Need
- An AI chatbot or meal-planning app
- Your daily calorie target (use a TDEE calculator)
- Macro split (protein/carbs/fat)
- Dietary restrictions (vegan, gluten-free, allergies)
- Weekly grocery budget
Step 1: Calculate Your Calorie Target
Use a free TDEE calculator or ask ChatGPT: "Calculate my TDEE given my age, weight, height, and activity level." Then adjust up or down 300–500 kcal based on goal.
Step 2: Define Dietary Rules
Tell the AI exactly what you eat and don't eat. Example: "I'm pescatarian, lactose intolerant, and hate mushrooms. Budget is $80/week for groceries."
Step 3: Request a Full Week Plan
Prompt: "Create a 7-day meal plan with 3 meals and 1 snack per day, hitting 1800 kcal, 140g protein, 180g carbs, 60g fat. Include grocery list with estimated costs."
Step 4: Review for Variety
Check that the plan has protein variety, 5+ vegetables, and no single food repeated more than 3 times. Ask the AI to swap anything you dislike.
Step 5: Import to a Tracker
Paste meals into MyFitnessPal or Cronometer to verify macros. Small edits often needed — AI estimates are 85–90% accurate.
Step 6: Batch Cook on Sunday
Group recipes with shared ingredients into a 2-hour Sunday prep. Ask the AI for a "batch cooking schedule" using your plan.
Common Mistakes
- Not specifying protein target — meals end up carb-heavy
- Ignoring prep time — a 60-min recipe won't happen on Tuesday
- Forgetting leftovers — plan for 2-serving recipes on busy days
- Skipping grocery list — you'll buy 20% more than needed
