Eating out while following a low FODMAP diet can feel like a daunting task. The low FODMAP diet is designed to minimize the intake of certain carbohydrates that can trigger digestive symptoms like gas, bloating, and abdominal pain. However, with careful planning, smart choices, and a little preparation, you can successfully integrate fast food and restaurant dining into your low FODMAP lifestyle. The goal isn't to achieve perfect adherence to any eating plan. Instead, it's about building the knowledge and confidence to make the best possible choices within whatever circumstances you're facing. Remember: Progress over perfection.
Understanding the Low FODMAP Diet
FODMAP stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols. These are short-chain carbohydrates that can be poorly absorbed in the small intestine, leading to fermentation by gut bacteria and subsequent digestive distress in sensitive individuals. The low FODMAP approach, developed by researchers at Monash University in Australia, involves temporarily limiting these carbohydrates to alleviate symptoms and identify individual triggers. This isn't about restriction-it's about abundance. Instead of focusing on what you can't eat, we celebrate the incredible variety of flavors and ingredients that support comfortable digestion.
The low FODMAP diet is a 3-stage elimination diet. The diet has three phases: an elimination phase, a reintroduction phase and a maintenance phase that’s customized to you. Take the data you gathered in the reintroduction phase and use it to develop a long-term eating plan. This plan will include the FODMAP foods that you tolerate and avoid the ones that cause symptoms.
Pre-Planning is Key
The most successful low FODMAP fast food experiences begin before you leave home. Smart preparation makes all the difference between a stressful fast food experience and a confident one. The goal isn't to carry a full pantry with you, but to have a few key items that can enhance safe choices and provide backup options when restaurant selections prove limited. Navigating fast food menus with digestive sensitivities doesn't have to feel like detective work. We've found that Gourmend customers who spend just 5-10 minutes researching before heading out report significantly more confidence and satisfaction with their fast food experiences.
- Check the Menu Online: Luckily, it’s now easier than ever to check out a restaurant’s menu online before you go. Take a look at the menu and make a note of any options that look like they’ll work for you. Once you arrive at the restaurant, you can confirm with the serving staff that the meal doesn’t include any high FODMAP ingredients.
- Call Ahead: If you cannot find menu information online, try calling the restaurant beforehand to see whether they can accommodate low FODMAP options. Restaurants appreciate being told in advance that they may need to make substitutions to suit your dietary needs, and this can provide peace of mind that you’ll be able to eat at the restaurant.
- Consider Gluten-Free Options: While gluten isn’t technically the problem on a low FODMAP diet, gluten-free options are also wheat-free. Since wheat is a significant source of FODMAPs, choosing gluten-free options can be an easy switch to ensure your meal is low FODMAP. Try choosing restaurants that offer a good range of gluten-free options.
- Dine During Off-Peak Hours: If possible, try to dine during times when the restaurant is not as busy. This will make it easier to chat with the server about your dietary needs and will ensure the kitchen has enough time to prepare your food.
- Bring a List of Foods to Avoid: Communication is key, and having a list of foods you need to avoid can be extremely helpful for the restaurant staff. Try to bring a printed list of the foods you need to avoid so that your server can provide it to the chef and ensure that no high FODMAP ingredients are added to your meal. Taking a written list of what you can’t have with you to restaurants takes the pressure off of you to remember everything, plus servers can share the list with the chef to verify ingredients in a dish.
- Keep the Rest of Your Meals Low FODMAP: FODMAPs tend to have a “bucket” effect. Everyone has a different-sized “bucket,” and it’s only once your FODMAP intake passes a certain threshold that symptoms appear. By keeping the rest of your day low FODMAP, you’ll ensure that your FODMAP “bucket” is almost empty when you go out to eat. That way, even if you eat some FODMAPs with your restaurant meal, they will be less likely to cause symptoms.
- Utilize Technology: Technology can be your greatest ally in navigating fast food with confidence. The Monash University FODMAP app remains the gold standard for ingredient checking and portion guidance. Many major chains now offer their own apps with detailed nutritional and ingredient information.
Ordering Strategies at Restaurants
The key to successful ordering lies in asking specific, actionable questions rather than expecting staff to understand complex dietary requirements.

Ask Specific Questions: In addition to the items you can’t have, give your server an idea of the foods you can have. List proteins, vegetables, fruits, grains, nuts and seasonings that are low FODMAP.
Be Aware of Hidden FODMAPs: Probably the most common FODMAPs on restaurant menus are garlic and onions. Make sure your server understands that this includes white, yellow and red onions, shallots, garlic salt and garlic and onion powder. Some meals might look suitable at first glance but are loaded with hidden FODMAPs. Sauces & Dressings: These often contain onion, garlic, honey, or high-FODMAP thickeners.
Choose Simple Dishes: At the restaurant, try to choose meals that can be easily adapted to be low FODMAP. The best low FODMAP choices at restaurants are dishes with straightforward ingredients-think grilled proteins, steamed vegetables, and plain starches like rice or potatoes.
Consider these options:
- Grilled or roasted chicken, beef, pork, or fish with low FODMAP veggies (eg green beans, zucchini) and rice or quinoa. Grilled proteins are often safe options for low FODMAP eating out. Be sure to ask whether the meat has been marinated or seasoned with high FODMAP ingredients like onion and garlic. If it has, ask if they can prepare the protein without these ingredients. Pair with a side of steamed vegetables and a carbohydrate like rice, quinoa, or potatoes for a complete meal.
- Salads are typically easy to tailor to your dietary requirements. Many dressings contain garlic, so ask if they can dress the salad with lemon juice or vinegar and olive oil instead (or bring your own dressing to use!). When ordering a salad, look out for high FODMAP ingredients like croutons and dried fruit. Custom Salads: Ask for a base of leafy greens with low FODMAP veggies like cucumber, tomato (small servings), carrot, and olives. Bring your own dressing, or ask for olive oil and lemon juice.
- Choose a gluten-free pizza base with plain tomato paste. Top the pizza with low FODMAP ingredients and request that they do not add any high FODMAP ingredients like onion or garlic to the toppings or sauce.
- Sushi/sashimi with fish or seafood and white or brown rice with soy sauce. Sushi Rolls: Choose rolls with simple fillings like cucumber, tuna, or egg. Many types of sushi are naturally low FODMAP. If you order rolls with avocado, limit your serving size, as avocado is high FODMAP in serving sizes of ¼ avocado or higher. You may also want to limit any rolls that contain tempura, as tempura is made with wheat flour, which is high FODMAP. The small amount of wheat found in soy sauce usually isn’t a problem for someone following the low FODMAP diet.
- Many restaurants will offer a gluten-free option for their pasta dishes. Be sure to check whether the seasonings and sauce have high FODMAP ingredients like onion, garlic, and cream, and ask if these ingredients can be omitted. Gluten-Free Pasta: Check that it’s made from a rice and maize or quinoa blend. Then request olive oil or a tomato-based sauce without garlic or onion.
- Omelettes: Great for brunch!
- Fries or Wedges: Ask how they’re seasoned (opt for no seasoning if it contains onion or garlic).
Don't Be Afraid to Customize: Don’t be afraid to order off the menu. Registered dietitian, Hannah Hunter, suggests chatting to wait staff and ordering a special meal if needed. Restaurants can usually accommodate simple requests like plain chicken breast or a piece of fish with potatoes and low FODMAP veggies like carrots or green beans.

Specific Restaurant Recommendations
Each major fast food chain has its own personality when it comes to low FODMAP friendliness. Some excel at simple, customizable options, while others require more creative navigation.
- Chipotle: Chipotle's assembly-line approach makes it the gold standard for low FODMAP fast food. Build your perfect bowl: Start with white rice (their safest base), add plain grilled chicken or steak, load up on lettuce and tomatoes, and add a moderate amount of cheese if you tolerate dairy.
- Five Guys: Verdict: Chipotle and Five Guys offer the most low FODMAP-friendly experiences due to their customization options and plain protein availability.
- McDonald's: McDonald's earns high marks for low FODMAP dining because of their willingness to customize orders and their straightforward ingredient lists. Your best bets: Order a Quarter Pounder with just the beef patty, lettuce, and tomato. Skip the bun or ask for it on the side. Their scrambled eggs are typically prepared plain, making them perfect for breakfast. McDonald's Pro Tip: Their beef patties are seasoned only with salt and pepper, making them one of the safest protein options in fast food.
- Chick-fil-A: While Chick-fil-A's grilled chicken breast is naturally low FODMAP, many of their other offerings require careful consideration. Safe approach: Order the grilled chicken breast plain, pair it with a fruit cup or side salad, and bring your own seasonings.
- Subway: Subway offers customizable sandwiches, which is a plus for managing IBS, but many breads, sauces, and toppings contain high FODMAP ingredients like onion and garlic. Choosing a gluten-free bread option and loading up on low FODMAP veggies like lettuce, cucumber, and tomatoes can work.
- Taco Bell: Taco Bell’s menu often features high FODMAP ingredients like onions, garlic, and beans in large portions, making it challenging. Some items can be adjusted by requesting no onions, no sauces, and choosing hard-shell tacos with plain protein and lettuce. Portion control is important, especially with ingredients like beans, which are only low FODMAP in very small amounts.
- Starbucks: Starbucks offers a few low FODMAP options if you choose carefully. Plain brewed coffee or espresso with lactose-free or plant-based milk like almond milk can work. For food, items like plain bagels without onion or garlic, or a simple fruit cup, are safer choices.
Navigating Beverages and Snacks
Beverages and snacks at fast food restaurants can be surprisingly tricky territory for low FODMAP dining.
- Beverages: The safest beverage approach at fast food restaurants is to stick with the basics. Reach for black coffee or espresso on a low FODMAP diet. Sweetener Sensitivity: While artificial sweeteners in diet sodas are technically low FODMAP, some people with IBS find that large quantities of certain sugar alcohols can trigger symptoms. Many fast food locations now offer flavored waters and enhanced beverages.
- Snacks: Fast food snacks require the same careful attention as main dishes. Reliably safe options include plain rice cakes (if available), basic potato chips without seasoning, and simple fruit cups containing safe fruits like grapes or oranges. Avoid flavored chips, seasoned nuts, and most packaged snacks available at fast food locations. Emergency Snack Strategy: Keep a small container of Gourmend seasoning and some plain crackers in your bag.
Managing Accidental FODMAP Consumption
The most important skill in low FODMAP fast food navigation isn't perfect ingredient knowledge-it's developing a healthy relationship with uncertainty and occasional mistakes. What matters is building confidence in your ability to make good choices most of the time, and knowing how to recover gracefully when things don't go as planned. Remember that the low FODMAP approach is about finding your personal threshold, not eliminating every possible trigger forever. Some people can handle small amounts of garlic powder in seasoning blends, while others need to be more careful.
Even with the best preparation and intentions, accidental FODMAP consumption happens to everyone following this dietary approach. When you accidentally consume high FODMAP ingredients, your body's response is typically temporary and manageable. These symptoms usually peak within a few hours of consumption and resolve within 24-48 hours for most people. Important Reminder: Accidental FODMAP consumption doesn't cause lasting damage to your digestive system.
When you realize you've consumed high FODMAP ingredients, gentle supportive measures can help minimize discomfort and speed recovery. Avoid the temptation to drastically restrict your eating or try unproven "detox" approaches. Learning Opportunity: Each accidental exposure provides valuable information about your personal tolerances and triggers.

Low FODMAP Staple Foods
No matter which phase of the low FODMAP diet you’re in, it’s a good idea to have some staple foods that you know you can have.
- ✅ Low FODMAP dairy products including, sour cream, cream, brie, feta, and hard cheeses like cheddar, swiss, and parmesan. Some dairy is high in lactose, but there are exceptions.
- ✅ Certain fruits like strawberries, pineapple, oranges, papaya, blueberries, and kiwi. Be careful with fruit though. Because fructose (fruit sugar) is a FODMAP, there are many fruits you’ll want to avoid. You don’t have to give up all FODMAP-containing foods even during the elimination phase of the low FODMAP diet.
- ❌ Legumes and pulses. Beans, beans make good soup… Beans are infamous for their gas-producing quality. So they’re a no-go on the low FODMAP diet.
- ❌ Certain vegetables like onions, garlic, asparagus, mushrooms, red peppers, beets, Brussels sprouts, butternut squash, cauliflower, leeks, and scallions. Vegetables vary widely when it comes to FODMAPs.
Low FODMAP Cuisine Specific Tips
- Italian Restaurants:
- Gluten free pizza bases and pasta: Many Italian restaurants now offer gluten free products. There is no wheat in gluten free products, making them a good choice on a low FODMAP diet. Please note though, those with coeliac disease should always double check there is no gluten contamination from ovens and benches.
- Tomato passata: Check with wait staff if the tomato passata used on pizza bases and in tomato based pasta sauces is free from garlic and onion. Many traditional restaurants will just make the sauce using tomatoes and salt.
- Choose hard cheeses if you are sensitive to lactose: the harder the cheese, the lower the lactose e.g. cheddar and parmesan. Some soft cheeses like haloumi and ricotta have a low FODMAP serve size, so check the app for quantities.
- Create your own: If you can choose your topping, choose low FODMAP foods e.g.
- Be aware of risottos: these can be a good low FODMAP option as they are made from rice, not wheat, but it is important to check whether the stock used contains onion and/or garlic.
- Chinese Restaurants: Many different sauces are used in Chinese cooking. Ask the wait staff if any of these contain, onion, garlic or artificial sweeteners (polyols). If they do, ask for your meals to be made with only low FODMAP sauces, like soy or oyster. Spring onion is often used as a garnish, so ask for green parts only or just leave it off all together.
- French Restaurants:
- A classic French dish of Steak Frites is steak served with chips, salad and often a sauce or mustard. Check if any of the sauces are onion or garlic free and if not, opt for a mustard and ask for the salad to be dressed with oil and vinegar.
- Salade Lyonnaise: This is a traditional French salad that contains lettuce, bacon, herbs, poached eggs and a mustard/vinegar dressing. Check with the waiters if it contains croutons and/or shallots (onions) and if these can be omitted.
- Nicoise salad: Similar to the Lyonnaise salad, this salad is made with tuna, olives, eggs, potato or rice and can be a good option. Just check for garlic and onion, croutons and also artichokes.
- Indian Restaurants: Many Indian dishes contain curry paste bases, often made with shallots and other onion varieties. Call the restaurant ahead and see if they can prepare something especially for you or give you a few options to choose from.
- Thai Restaurants: Many dishes can be made without onion or garlic.
- Japanese Restaurants: Sushi is a solid choice.
Remember Your Other IBS Triggers
While it’s possible to choose low FODMAP options when dining out, it’s important to remember that FODMAPs are not the only cause of symptoms for people with IBS. Some of the other triggers for IBS symptoms include:
- High-fat meals
- Spicy food
- Alcohol
- Caffeine
Try to be mindful of these other IBS triggers to ensure you’re not inadvertently eating non-FODMAP foods that could cause symptoms.
