Have you been told to try a low FODMAP diet and then left to work out what that means at six on a Tuesday evening? It is one of the few eating patterns that is genuinely complicated, because the list is long, the amounts matter, and the whole thing is supposed to change over time rather than stay fixed.
Short answer: AI Low-FODMAP Meal Planner builds meal plans for whichever phase you are in, whether that is strict elimination, structured reintroduction, or the personalised long term diet you end up with afterwards.
What is AI Low-FODMAP Meal Planner?
AI Low-FODMAP Meal Planner is a free planning tool for people following a low FODMAP diet, usually under the guidance of a dietitian or doctor for symptoms of irritable bowel syndrome. You say which phase you are in and what you can currently tolerate, and it builds meals to match.
The reason it needs its own tool is that low FODMAP is not a single diet. It is a three stage process, and the food changes at every stage. A plan built for week one of elimination is wrong for someone testing fructans in week nine, and both are wrong for someone eighteen months in with a personal list of what they tolerate.
Who Should Use It?
People working through the protocol, and the people cooking for them.
- Anyone starting elimination, where onion and garlic disappearing from cooking is the first shock.
- People in the reintroduction phase, who need an otherwise stable diet while one group is tested.
- Anyone in the personalisation phase with their own list of tolerances to plan around.
- Household cooks feeding one person on the diet and others who are not.
- People eating out or travelling who need a plan that survives a week away.
Key Features
Phase aware
Tell it whether you are eliminating, reintroducing or personalising and the plan changes accordingly.
Portion sensitive
Many foods are fine in small amounts and not in large ones, so quantities are stated rather than implied.
Flavour without the triggers
Garlic infused oil, spring onion tops, chives and herbs replace what elimination takes away.
Reintroduction friendly
Keeps the background diet stable so a single test food is the only thing changing.
Your own tolerance list
In the long term phase, the plan works from what you personally tolerate rather than a generic list.
Why Use AI Low-FODMAP Meal Planner?
Because this is the hardest of the common eating patterns to improvise. Onion and garlic are in almost every stock, sauce and ready meal, wheat is in most bread and pasta, and several ordinary fruits are off the list at ordinary portions. Cooking without any of them takes a repertoire most people simply do not have on day one.
The second reason is that reintroduction only works if everything else stays still. If the background diet drifts while you are testing lactose, the result is meaningless. A written plan holds the baseline steady, which is exactly what the protocol requires.
Where it is strong
- Understands that the diet has phases and plans for the one you are in
- States portion sizes, which is where most low FODMAP mistakes happen
- Replaces onion and garlic flavour rather than leaving food bland
- Keeps the baseline stable during a reintroduction test
- Works from your personal tolerance list in the long term
Where it falls short
- FODMAP content data is updated regularly and a generated plan may lag it
- Thresholds are personal, so a portion that suits one person may not suit you
- It cannot diagnose anything, and this diet needs a diagnosis behind it
- It is not a replacement for a dietitian, who the protocol assumes you have
Best Use Cases
The protocol runs in a specific order, and the plan should match wherever you are in it.
- Elimination. Two to six weeks, high FODMAP foods removed, aiming to see whether symptoms settle at all. Ask for a strict plan with named portions.
- Reintroduction. One FODMAP group tested at a time over several days, with everything else held constant. Ask for a stable background week plus a slot for the test food.
- Personalisation. Your own list of tolerated foods and amounts, kept as wide as symptoms allow. Give the tool your list and ask it to plan from that.
| Commonly removed | Usually tolerated instead | Watch out for |
|---|---|---|
| Onion and garlic | Garlic infused oil, chives, green tops of spring onions | Stock cubes and ready made sauces almost always contain both |
| Wheat bread and pasta | Sourdough spelt, oats, rice, quinoa | Portion size still matters with wheat, it is not always all or nothing |
| Apples, pears, mango | Oranges, grapes, strawberries, firm bananas | Ripeness changes the FODMAP content of bananas |
| Milk and soft cheese | Lactose free milk, hard cheeses | Lactose free is not the same as dairy free, which confuses many labels |
Advanced Options Guide
Ten controls sit in the Advanced Options accordion. On this tool the phase and your tolerance list, both typed into Custom Instructions, matter more than any dropdown.
| Option | What it controls | When to change it | Suggested starting point |
|---|---|---|---|
| Servings | Portions per meal | Raise it so leftovers cover a safe lunch the next day | 4 |
| Difficulty | Technique the recipes assume | Easy, because this diet is already demanding enough | Easy |
| Prep Time | Time band per meal | Standard, since almost everything is cooked from scratch | Standard (15-30m) |
| Cuisine | The culinary direction | Avoid cuisines built on onion and garlic bases during elimination | General |
| Include Nutrition Info | Estimated calories and macros | On if fibre intake is a concern, which it often is here | On |
| Include Substitutions | Swap suggestions per ingredient | Keep on, and check each swap against a current FODMAP source | On |
| Include Time Estimates | Prep and cook times | On for weekday planning | On |
| Include Storage Tips | Fridge life and freezing | Important, since safe leftovers are worth more on this diet | On |
| Ingredient Complexity | How unusual ingredients may be | Lower it, since substitutions are already doing a lot of work | Around 30 |
| Custom Instructions | Free text for phase and tolerances | Name your phase and list what you already know you tolerate | State your phase here |
How Does AI Low-FODMAP Meal Planner Work?
It runs on a single page. You describe your week in the prompt box at the top, then pick an engine from the model selector, which offers MSB AI by default plus Anthropic Claude AI, OpenAI ChatGPT, Google Gemini, DeepSeek, Qwen, xAI Grok AI, Meta AI, NVIDIA AI, OpenRouter AI and MiniMax. The Advanced Options accordion sits between the selector and Generate.
Results appear in an output card with a live word count in the footer. Copy, Listen, Reuse and Download sit with each result, and the export row writes DOC, TXT or HTML. On this tool the export is worth using properly, because many people bring their plan to a dietitian appointment, and a DOC file is easier to annotate than a screenshot. Reuse is the control that fits the protocol best: during reintroduction you want the same background week regenerated with one food changed, and Reuse puts the previous description straight back in the prompt so nothing else drifts. The activity history panel keeps every version from your session, which effectively gives you a record of what you tested and when.
Example Inputs
The phase is the first thing to say. Here is an input that lets AI Low-FODMAP Meal Planner plan for a real situation rather than a generic one.
I am in week three of strict elimination, working with a dietitian. Seven dinners and five portable lunches for one person, cooked in a household where two others eat normally. No onion, no garlic, no wheat bread or pasta. I tolerate lactose free dairy and hard cheese. I have garlic infused oil. Weeknights under thirty minutes. Please give portion sizes in grams for anything where the amount affects whether it is low FODMAP, and suggest meals where the others can add onion to their own portions at the end.
Ask for the amounts This diet turns on portion size more than on any list. A meal can be fine at eighty grams of a food and not at a hundred and fifty. Asking for gram quantities on the borderline ingredients is the most useful instruction you can give.
Example Outputs
A good elimination plan reads like ordinary cooking with the aromatics swapped. Instead of a soffritto of onion and garlic, dishes start with garlic infused oil, the green parts of spring onions, carrot, celery and herbs. Nothing tastes stripped down, which is the main thing that makes elimination survivable for six weeks.
You should see quantities attached to the borderline items and nothing at all attached to the safe ones. If the plan says two hundred grams of sweet potato in one place and simply says spinach in another, that is correct rather than inconsistent, because only one of those has a threshold worth watching.
A reintroduction plan looks different again. The week itself should be dull and repetitive on purpose, with one clearly marked test food appearing on specific days in increasing amounts. If the output starts varying the background meals during a test, ask it to hold them constant. Stability is the whole point of that phase.
Tips & Common Mistakes
- ✅ Your phase is stated explicitly in the prompt
- ✅ Portion sizes are given for anything with a threshold
- ✅ Stock, sauces and ready made items are named rather than assumed safe
- ✅ During reintroduction, the background week is held constant
- ✅ Fibre sources are present, since elimination often reduces them
- ✅ You have checked anything uncertain against a current FODMAP reference
The mistakes that matter most: staying in elimination indefinitely, which is not what the protocol is for and narrows the diet unnecessarily; assuming a food is either allowed or banned when the real answer is a quantity; and forgetting that stock cubes, gravy and most jarred sauces contain onion and garlic even when the label mentions neither by name.
This diet is meant to be supervised The low FODMAP protocol is designed to be followed with a dietitian, after a proper diagnosis, and it is not intended to be permanent. Persistent digestive symptoms need investigating by a doctor first, because several conditions share them. AI Low-FODMAP Meal Planner offers general information only. It cannot see you, cannot diagnose anything, and its food classifications may lag current research. Check anything important with your dietitian or doctor and with an up to date FODMAP reference.
Comparison Table
| Approach | Good for | Where it falls down |
|---|---|---|
| A printed list of safe foods | Quick reference in a shop | Tells you nothing about how to make a meal |
| FODMAP app with food lookups | Checking a specific ingredient and portion | Still leaves you to plan the week |
| Dietitian appointments | The authoritative guidance, and the phase timing | Limited time, so meal ideas are usually brief |
| AI Low-FODMAP Meal Planner | Turning your phase and tolerances into a week of food | Not a diagnostic or clinical source, so verify the classifications |
Get garlic infused oil early It is the single item that makes elimination feel like cooking rather than like deprivation. The flavour compounds dissolve in oil and the problematic fructans do not, so infused oil is usually fine when garlic itself is not.

Frequently Asked Questions
Is the planner free?
Yes, with no account and no payment. You can generate a plan for each phase and keep regenerating as your tolerances change.
Should I start this diet on my own?
It is not recommended. The protocol assumes a diagnosis and dietitian support, partly because ongoing digestive symptoms can have several causes that need ruling out first, and partly because elimination narrows the diet in ways that need managing. See a doctor before starting.
How long does elimination last?
Usually between two and six weeks. It is deliberately temporary. Staying on it long term is one of the most common mistakes and it is not what the protocol intends.
Can it plan a reintroduction challenge?
It can build the stable background week and place a marked test food on specific days. The design of the challenge itself, including which group to test and in what amounts, should come from your dietitian.
Are the food classifications reliable?
Treat them as a helpful starting point rather than an authority. FODMAP data is updated as research continues, and portion thresholds are revised. Check anything you are unsure of against a current reference.
Can it cope with other restrictions at the same time?
Yes, though it narrows things considerably. Vegetarian low FODMAP is workable but takes care, because many legumes are high FODMAP. State everything in Custom Instructions and expect a shorter list of meals.
Low FODMAP is a process rather than a diet, and processes need structure more than they need willpower. Getting the current phase written down as actual meals, with the amounts named, removes most of the daily difficulty and leaves you free to concentrate on what the phase is meant to teach you.
