Restaurant Tips for Choosing the Low FODMAP Diet:
Sticking to a low FODMAP diet can be life-changing for those managing symptoms of Irritable Bowel Syndrome (IBS), bloating, gas, and digestive discomfort. However, eating out while on this diet can seem overwhelming at first. Restaurant menus contain hidden ingredients such as garlic, onion, lactose, and high fructose foods that can trigger symptoms. The good news is that eating out can still be enjoyable and symptom-free with some preparation, clear communication, and innovative food choices. This guide provides practical advice on how to eat on a low FODMAP diet, including what to order, what to avoid, and where to go when you are on the go.
Why eating out can be Tricky on the Low FODMAP Diet
 The low FODMAP diet restricts certain types of carbohydrates that are poorly absorbed in the gut. These include fermentable oligosaccharides, disaccharides, and polyols, hence the acronym FODMAP. Common high-FODMAP ingredients like garlic, onion, wheat, milk and some fruits can show up in unsuspecting dishes, especially in restaurants where the exact ingredients and preparation methods are not always disclosed.
Step 1: Plan Before You Diet Out
One of the most effective tips for eating on a low-FODMAP diet is to do some research beforehand. Most restaurants now offer online menus, and some even provide allergen information.
What to Look for:
- Dishes with simple ingredients: grilled meats, steamed vegetables, plain rice or potatoes.
- Customizable meals like bowls, salads, or stir-fries.
- Look for options that are marked gluten-free (although gluten-free doesn’t always mean FODMAP-friendly, it often eliminates wheat-based triggers).
Pro Tip:
Call ahead and ask the restaurant if they can accommodate your dietary needs. Many places are willing to prepare meals without garlic, onion, or dairy when given notice.
Step 2: Communicate Clearly with Your Server
Once you are at the restaurant, don’t be shy about asking questions. Your goal is to avoid surprises that could trigger symptoms later.
Sample Questions:
- Is this dish made with garlic or onion?
- Can I have this grilled plain with no seasoning or sauce?
- Are there any dairy products or sweeteners in this dressing?
When you’re polite and respectful, most servers and chefs will do their best to help. Clear communication is key when figuring out how to eat low FODMAP at a restaurant.
Step 3: Stick to the Basics
To minimise risk, choose foods with minimal preparation and fewer ingredients. These are more likely to be safe and easier to modify.
Safe Low-FODMAP Restaurant Foods Include:
- Grilled chicken, beef, or fish without marinades
- Baked potatoes or plain white/brown rice
- Steamed vegetables like carrots, green beans, zucchini, or spinach
- Egg (boiled, scrambled, or poached; avoid omelettes with milk or fillings)
- Mixed greens or basic side salads with lemon juice or olive oil
Skip anything sautéed, creamy, or labelled spicy, as these often contain garlic, onion, or high-FODMAP spices.
Step 4: Know Which Restaurants Are FODMAP-Friendly
While almost any restaurant can work with the right communication, some places naturally offer more suitable choices for FODMAP eaters. Below are some low-FODMAP-friendly restaurants and menu suggestions:
Good Restaurants for the Low FODMAP Diet:
- Chipotle: Create a custom bowl with white rice, carnitas (the only low-FODMAP meat), lettuce, and a small portion of cheese.
- Panera Bread: Build-your-own salads with grilled chicken, no croutons, no onion, and olive oil for dressing.
- Chick-fil-A: Grilled nuggets with waffle fries and a side salad (without dressing).
- P.F. Chang’s: Choose from their gluten-free menu and request no garlic/onion in stir-fries or rice bowls.
- Five Guys: Bunless burger wrapped in lettuce with plain toppings like tomato or mustard.
These restaurants are not certified FODMAP safe, but offer options that can be customised to your needs.
Step 5: Navigating Fast Food on a Low FODMAP Diet
Sometimes, fast food is the only option, especially when travelling. While fast food isn’t ideal, certain chains can work in a pinch if you know what to ask for.
Best Low FODMAP Fast Food Restaurants & Orders:
- McDonald’s: Grilled chicken sandwich (no bun, no sauce), side salad with lemon wedges or plain oil.
- Subway: Salad with grilled chicken, lettuce, spinach, cucumber, tomato, onion, sauces, and croutons.
- Taco Bell: Power Bowl with rice, grilled chicken, lettuce, no beans, cheese, or sour cream.
- Starbucks: Egg bites (some flavours are low FODMAP), plain oatmeal with a banana.
When eating low-FODMAP fast food, always skip the sauces, dressings, and processed sides, which often contain garlic, onion powder, or lactose.

Step 6: Be Careful with Sauces, Marinades, and Spices
Sauces are a common hiding place for high-FODMAP ingredients. Garlic and onion are used in nearly every sauce, broth, marinade, and spice blend.
Tips to Stay Safe:
- Always ask for sauces on the side or remove them entirely.
- Bring your low-FODMAP sauce (like a small container of tamari or lemon vinaigrette).
- Stick with fresh herbs, lemon juice, or olive oil to flavour your food.
Step 7: Explore Asian and Mediterranean Options
Asian and Mediterranean cuisines often provide simpler, grilled meals with rice or vegetables. This makes them some of the best restaurants for the low FODMAP diet, as long as you watch for hidden ingredients.
What to Order:
- Sushi rolls with cucumber, egg, and fish (no imitation crab or avocado)
- Pho with plain rice noodles and broth (confirm it’s garlic/onion-free)
- Greek grilled meats like chicken souvlaki with rice and salad ( no pita or tzatziki unless confirmed safe)
Avoid soy sauce (opt for gluten-free tamari), garlic chilli pasta, or hummus unless it’s homemade and verified low FODMAP.
Step 8: Keep Emergency Snacks on Hand
Even with the best intentions, mistakes happen. Keep low-FODMAP snacks in your bag in case you find yourself somewhere without safe options.
Handy Snacks Ideas:
- Plain rice cakes
- Lactose-free cheese
- Small banana or unripe kiwi
- Almonds (limit to 10)
- Low-FODMAP protein bars
Conclusion
Eating a low-FODMAP diet doesn’t have to be a source of stress or frustration. With thoughtful preparation, a few meals to choose from, and clear communication with restaurant staff, you can still enjoy social outings, travel, and simple meals without compromising your digestive health.
The key to success is learning how to eat out on a FODMAP diet in a way that works for your body and lifestyle. Whether you’re stopping at a low-FODMAP fast food restaurant, planning a night out at one of your favourite low-FODMAP-friendly restaurants, or just trying to grab a quick bite, remember: it’s all about making informed choices. Stick to whole foods, skip the sauces, and don’t be afraid to ask for what you need. Over time, you’ll build the confidence to navigate any menu with ease.
