Free Meal Plan Generator for Macros and Preferences

Is this meal plan generator automatic?

Yes! When you submit your data using the form above, a unique meal plan will be automatically created. The generator takes your calories, macros, diet type, and allergy preferences, and builds a complete one-day plan with breakfast, lunch, and dinner. Each plan is generated from our database of 220+ whole foods with verified nutrition data — no generic templates. For a full 7-day plan with grocery lists, meal swapping, and progress tracking, check out the full version of our AI Meal Planner.

How does the macro calculator work?

The macro calculator uses the Mifflin-St Jeor equation, the gold standard recommended by the Academy of Nutrition and Dietetics, to estimate your Basal Metabolic Rate (BMR). It then multiplies by your activity factor (1.2× to 1.9×) to determine your Total Daily Energy Expenditure (TDEE), and applies a goal adjustment: −500 kcal/day for weight loss, +300 kcal/day for muscle building, or no change for maintenance. Safety floors of 1,500 kcal/day for men and 1,200 kcal/day for women are always enforced. Each diet type applies a specific macro split:

How does the meal plan creator work?

The meal plan creator uses a multi-stage pipeline. First, AI selects ingredients that match your diet type, respect your food allergies, and create tasty, balanced meals. Then a mathematical feasibility gate checks whether those ingredients can physically reach your macro targets — if not, it automatically swaps ingredients from the database. Finally, a precision solver adjusts every ingredient's portions to hit your exact calorie and macro targets within ±10% deviation. This is not a simple calorie counter — it's a real optimization engine that ensures every plan is nutritionally accurate.

Is this meal plan generator free?

Yes! This meal plan generator is completely free to use with no signup or email required. You can generate 1 plan per day. For unlimited 7-day meal plans with grocery lists, individual meal swapping, macro tracking, and auto-renewal, try the full AI Meal Planner.

What's the difference between the free plan and the full weekly planner?

Does this meal planner work for vegetarians and vegans?

Yes! By selecting Vegan or Vegetarian as your diet type, the generator will only select plant-based or lacto-ovo vegetarian ingredients. This is particularly helpful for following a high-protein vegetarian or vegan diet — the solver will find the right combination of legumes, tofu, tempeh, nuts, and grains to hit your protein target without animal products.

How accurate are the macros in the generated meal plan?

All generated meal plans target ±10% macro accuracy across protein, carbs, and fat. This is achieved through a three-step process: ingredient feasibility validation, automatic ingredient swapping when deviations are detected, and a regularized least-squares solver that precisely adjusts portions. All nutrition data comes from our verified database of 220+ whole foods with macros per 100g.

Can I personalize my meal plan further?

The free generator supports 8 diet types, 2–4 meals per day, custom calorie targets, custom macro targets, and 9 food allergy filters. For even deeper customization — including specific food preferences, meal swapping, grocery lists, and weekly plan auto-renewal — use the full AI Meal Planner. You can set different macros for each day, pre-set meals you want to keep, and have the generator plan around them.

Does this meal planner use AI?

Yes, AI is used to select ingredients and create varied, diet-appropriate meals. However, the macro accuracy doesn't rely on AI alone — it uses proprietary mathematical optimization algorithms (feasibility gate + least-squares solver) to guarantee that every plan hits your nutritional targets. It's not just a wrapper for a chatbot.
