Best Free Diet Plan Generators (2026): Tested + What Reddit Recommends

A diet plan generator is a tool that builds a personalized eating schedule automatically from your stats and goal — instead of you researching macros and writing a meal plan by hand. Eat This Much is the one Reddit mentions most often for hitting exact calorie and macro targets for free. Strongr Fastr and Prospre are close seconds for macro-focused plans. None of them touch your workout — that's the specific gap PonteFuerteAI fills by generating the meal plan and the training plan from the same numbers.

Best Diet Plan Generators Compared

Tool	Free tier	Grocery list	Workout plan
Eat This Much	Full (with ads)	Yes	No
Strongr Fastr	Full	No	No
Prospre	Limited	Yes	No
My Diet Meal Plan	Full	No	No
PonteFuerteAI	Full	No	Full + AI programs

1. Eat This Much — Best Free Generator Overall

Best for: people who want an exact calorie and macro target hit automatically, with a grocery list.

This is the name that comes up most across Reddit threads asking for a free meal plan generator. It builds a full week from your calorie target, dietary style (keto, vegan, etc.), and budget, and swaps out individual meals you don't like.

Main limitation: the free tier includes ads, and it doesn't track workouts or adjust your calories based on training.

2. Strongr Fastr — Best for Macro-Focused Plans

Best for: people who already know their macro targets and want a plan built strictly around them.

Strongr Fastr's generator is fitness- and macro-first rather than recipe-first — you get a daily nutrition layout that hits your numbers with less emphasis on variety or grocery-list automation.

Main limitation: no grocery list, no workout integration.

3. Prospre — Best for Grocery Automation

Best for: people who want the plan and the shopping list generated together.

Prospre generates a custom plan from your macros along with a grocery list and recipes, which makes the ready-to-cook step faster than tools that only output a meal list.

Main limitation: full customization sits behind a paid tier.

4. My Diet Meal Plan — Best No-Frills Free Option

Best for: people who want a straightforward calorie-limited plan with restriction toggles and nothing else to configure.

Main limitation: no grocery list, no macro breakdown by meal, no training integration.

5. PonteFuerteAI — Best for Also Getting a Workout Plan

Best for: people who train and want their meal plan and workout plan generated from the same numbers, not two separate tools.

Every generator above solves food. None of them solve training. PonteFuerteAI generates the meal plan and an AI workout program together, so your calorie target reflects your actual training days instead of a flat number that ignores whether you lifted today. Meals log with a photo instead of a manual search.

Main limitation: it is not a pure recipe-discovery tool — if your only goal is maximum recipe variety with no fitness component, Eat This Much or Prospre cover that better.

What Reddit Actually Recommends

Asked for a genuinely free, no-subscription option, one of the clearest answers on this exact question: "I want to stop having to spend so much time thinking about what I am going to eat. I'm looking for something that is barebones. Calculates caloric intake..." and builds a plan around it without a paywall. (r/EatCheapAndHealthy, "Is there an actual free/non-subscription simple meal planner?", 40+ comments) The most common answer across replies to questions like this is Eat This Much, echoed in its own dedicated praise thread: "It's great for generating meal plans! This one also allows to generate meal plans for free..." (r/1500isplenty, "EatThisMuch meal plan generator is a great tool!", 20+ comments) A thread specifically comparing options for cost got the same recommendation: "A friend recommended the website Eatthismuch.com, after i expressed my desire for automating my meal planning. The site is great, but I'm just not in..." the target audience for every feature it offers. (r/Frugal, "Any free meal plan generator sites/apps?")

A more recent thread frames the same request through an AI lens specifically: "I know it's a lot to ask but since AI is taking such a huge turn for how well it's performing I was wondering if anybody knows of an AI or website..." that can build a full plan automatically rather than a static PDF. (r/gainit, "Any websites or apps that will generate a meal plan for me?", 10+ comments) And in a thread specifically about combining planning with prep, the feature people actually value most isn't the recipes themselves: "Things I LOVE: Generates meals for the week, recipes can be swapped if I don't like them, Generates shopping..." lists automatically so there's no manual list-building step left. (r/MealPrepSunday, "Best app for meal planning/prep?", 130+ comments)

The Gap: None of These Adjust for Training

Every generator here treats your calorie target as a fixed number you set once. In practice, that number should move with how much you're training — a heavy lifting week needs more fuel than a rest week, and a flat plan either underfeeds you on hard days or overfeeds you on easy ones. PonteFuerteAI's target adjusts as you log workouts instead of staying static, which is the specific problem a pure meal-plan generator can't solve on its own.

Frequently Asked Questions

What is the best free diet plan generator?

Eat This Much is the option Reddit recommends most consistently for a genuinely free, no-subscription plan built around your calorie and macro targets, with a grocery list included.

Is there an AI diet plan generator that's actually free?

Yes — Eat This Much, Strongr Fastr, My Diet Meal Plan, and PonteFuerteAI all have functional free tiers that generate a full plan without requiring payment upfront.

Can ChatGPT create a meal plan?

ChatGPT can draft a meal plan, but it doesn't know your exact calorie needs unless you calculate them yourself first, and it can't automatically build a grocery list or adjust the plan as your weight or training changes the way a dedicated generator does.

Does any diet plan generator also create a workout plan?

PonteFuerteAI is the option built specifically for that — it generates an AI workout program alongside the meal plan and adjusts your calorie target based on logged training, which none of the meal-only generators do.
