Low-FODMAP meal plan: 7 days for a calmer gut

Roughly 1 in 7 adults — about 11% of the global population — lives with irritable bowel syndrome (IBS), and for many of them, food is both the trigger and the treatment. If your stomach feels like a science experiment after every meal, a structured low-FODMAP meal plan can give you back something most diets can't: predictable, peaceful digestion. This guide walks you through what FODMAPs are, exactly what to eat for the next seven days, and how to stop spending Sunday afternoons cross-referencing food lists.

What is a low-FODMAP diet, and how does it work?

A low-FODMAP diet is a short-term, evidence-based eating plan that limits fermentable carbohydrates known to trigger IBS symptoms like bloating, gas, cramping, and altered bowel habits. Developed by researchers at Monash University, it follows three phases — elimination (2–6 weeks), reintroduction (6–8 weeks), and personalization. Studies show up to 75% of people with IBS report meaningful symptom relief on the protocol.

FODMAP stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, And Polyols — short-chain carbohydrates that pull water into the small intestine and ferment quickly in the colon. In sensitive guts, that fermentation produces the gas, bloating, and pain that defines IBS. The fix isn't avoiding carbs forever; it's learning which specific FODMAPs your body reacts to and at what amounts.

Who should try a low-FODMAP meal plan?

The low-FODMAP diet was designed for people with IBS, but research suggests it may also help with:

Functional bloating and chronic gas
Small intestinal bacterial overgrowth (SIBO)
Inflammatory bowel disease (IBD) during flares, under medical supervision
Functional dyspepsia and indigestion

If you don't have a confirmed digestive condition, the diet probably isn't the right tool. It's restrictive by design and not meant to be permanent. Always consult a registered dietitian or gastroenterologist before starting, especially if you have a history of disordered eating.

Low-FODMAP foods to eat (and high-FODMAP foods to avoid)

One of the most-Googled questions on this diet is simply what can I eat? Below is a snapshot of the most common low- and high-FODMAP foods. For exact portion thresholds, the Monash University FODMAP Diet App is the gold standard.

Low-FODMAP foods (your “yes” list)

Proteins: chicken, turkey, beef, pork, eggs, firm tofu, tempeh, salmon, tuna, cod, shrimp
Vegetables: spinach, kale, zucchini, carrots, cucumber, bell peppers, eggplant, potatoes, lettuce, green beans, bok choy, tomatoes
Fruits: strawberries, blueberries, raspberries, oranges, kiwi, grapes, pineapple, unripe banana, cantaloupe (1/2-cup serving)
Grains: white and brown rice, quinoa, oats (1/2 cup), gluten-free bread and pasta, polenta, corn tortillas, sourdough spelt
Dairy: lactose-free milk and yogurt, hard cheeses (cheddar, parmesan, brie, feta), almond milk
Nuts and seeds: walnuts, pecans, peanuts, macadamias, chia seeds, pumpkin seeds, sunflower seeds (in 1-tablespoon portions)
Fats and flavor: olive oil, butter, garlic-infused oil, scallion green tops, fresh herbs

High-FODMAP foods to avoid during elimination

Vegetables: garlic, onion, leeks, asparagus, cauliflower, button mushrooms, artichoke, sugar snap peas
Fruits: apples, pears, watermelon, cherries, mango, peaches, plums, dried fruit
Grains: wheat, rye, and barley in large amounts
Dairy: regular cow's milk, ice cream, soft cheeses (ricotta, cottage cheese), regular yogurt
Legumes: chickpeas, lentils, kidney beans, black beans (canned and rinsed are sometimes tolerated)
Sweeteners: honey, agave, high-fructose corn syrup, sorbitol, mannitol, xylitol

Garlic and onion are the two biggest hidden culprits — they're in nearly every restaurant sauce, marinade, and seasoning blend. Garlic-infused olive oil is your best friend: the FODMAPs in garlic are water-soluble and don't transfer into oil, so you keep the flavor without the trigger.

The three phases of the low-FODMAP diet

Phase 1: Elimination (2–6 weeks)

Strictly remove all high-FODMAP foods. The goal is to give your gut a baseline of relief — most people notice a difference within 1–2 weeks. Don't extend this phase beyond six weeks. Long-term restriction can reduce gut microbiome diversity, which is the opposite of what most IBS sufferers actually need.

Phase 2: Reintroduction (6–8 weeks)

Reintroduce one FODMAP group at a time — for example, lactose, then fructose, then fructans — in small, then larger doses, while tracking symptoms in a journal. This is the most important phase. It tells you exactly which FODMAPs you can tolerate, and at what amounts. Skipping it is the most common reason the diet fails long-term.

Phase 3: Personalization

Build a long-term diet that's as varied as possible, only avoiding the specific FODMAPs and portions that trigger your symptoms. Most people end up eating a much wider range of foods than they expected after this step — including some they'd written off entirely.

7-day low-FODMAP meal plan

This 7-day low-FODMAP meal plan covers the elimination phase. Every meal is built from low-FODMAP ingredients in standard Monash-tested portions, with roughly 1,800–2,200 calories per day. Scale portions up or down based on your needs and goals.

Pro tip: Use garlic-infused olive oil and the green tops of scallions (the green tops are low-FODMAP; the white bulbs are not) to add flavor without triggering symptoms.

Breakfast: Two scrambled eggs with spinach and feta on a slice of sourdough spelt, plus a handful of strawberries.
Lunch: Grilled chicken bowl with quinoa, cucumber, cherry tomatoes, bell pepper, and lemon-olive oil dressing.
Snack: Lactose-free Greek yogurt with 10 blueberries and a drizzle of maple syrup.
Dinner: Pan-seared salmon with roasted potatoes, zucchini, and carrots tossed in garlic-infused oil.

Day 2 — Tuesday

Breakfast: Overnight oats with 1/2 cup rolled oats, lactose-free milk, chia seeds, raspberries, and a spoon of peanut butter.
Lunch: Tuna salad in butter lettuce wraps with cucumber, carrot, and olive-oil mayo; rice crackers on the side.

This single week alone covers more than 30 distinct low-FODMAP ingredients — far more variety than most people manage on their own when they first start the protocol.

Your low-FODMAP grocery list

The second-biggest cause of FODMAP burnout (after restaurant menus) is the grocery store. Here's a one-week shopping list that maps to the meal plan above. Adjust quantities for your household size.

Proteins: 6 chicken breasts, 1 lb beef strips, 2 salmon fillets, 1 cod fillet, 1 lb shrimp, 1 lb ground turkey, 1 small steak, 1 can tuna, 1 dozen eggs, 6 oz turkey deli slices, 4 strips bacon
Dairy: lactose-free milk, lactose-free Greek yogurt, lactose-free cottage cheese, feta, cheddar, parmesan, mozzarella, brie, butter
Produce: spinach, kale, romaine, butter lettuce, arugula, zucchini, carrots, cucumber, bell peppers, cherry tomatoes, bok choy, green beans, scallions (greens only), potatoes, sweet potato, lemons, ginger, fresh basil, oregano, dill
Fruit: strawberries, blueberries, raspberries, grapes, pineapple, kiwis, oranges, unripe bananas
Grains and starches: rolled oats, quinoa, jasmine rice, brown rice, polenta, rice noodles, rice cakes, gluten-free sourdough, gluten-free pizza crust, buckwheat flour, sourdough spelt

How to follow a low-FODMAP meal plan without spending hours planning

The biggest reason people quit the low-FODMAP diet isn't symptoms — it's logistics. Reading every label, checking portion thresholds in the Monash app, and finding three new low-FODMAP recipes every day quickly becomes a part-time job. Most dietitians say the protocol fails or stalls in week two or three, almost always because of decision fatigue rather than digestion.

That's exactly what MealFrame, an AI-powered meal planning and nutrition tracking app, automates. You set low-FODMAP as a dietary preference, plug in any extras (lactose-free, gluten-free, calorie target, allergies, household size), and MealFrame builds a complete week of meals — every recipe FODMAP-safe at standard Monash-tested portions, every grocery list organized by aisle, every macro counted. Found a salmon dish you love? Save it, and MealFrame will rotate it back into future weeks. Heading out and want to swap dinner? One tap regenerates a single meal without breaking the rest of the plan. Scan a packaged food with your camera and MealFrame instantly tells you whether it fits your low-FODMAP plan.

For people with IBS, that automation is the difference between I'll try this for two weeks and actually completing the full elimination, reintroduction, and personalization protocol the way it was designed to be done.

Common mistakes to avoid on a low-FODMAP diet

Skipping the reintroduction phase. This is the most common — and most damaging — mistake. Staying in elimination indefinitely starves the beneficial gut bacteria that thrive on fiber and prebiotics, and it isn't how the diet was designed to work.
Ignoring portion sizes. Many foods (avocado, sweet potato, oats) are low-FODMAP only at specific portions. Eat double, and you've eaten a high-FODMAP meal.
Stacking small “low” servings. Three different low-FODMAP foods in one meal can add up to a high-FODMAP load. Spread your “freebies” across the day.
Hidden garlic and onion. Stocks, broths, prepared sauces, salad dressings, and “natural flavors” frequently contain both. Read every label.
Doing it alone. A registered dietitian who specializes in FODMAPs can shave weeks off the process and prevent unnecessary restriction.

Frequently asked questions

How long should I stay on a low-FODMAP diet?

Stay strictly low-FODMAP for 2–6 weeks during the elimination phase, never longer. Then move into a structured 6–8 week reintroduction phase, testing one FODMAP group at a time. After that, follow a personalized maintenance diet that limits only the specific FODMAPs that trigger your symptoms.

Is a low-FODMAP diet the same as gluten-free?

No. Many low-FODMAP foods are not gluten-free (sourdough spelt is one example), and many gluten-free products contain high-FODMAP ingredients like inulin, honey, or apple juice concentrate. The two diets only overlap in that both limit large amounts of wheat.

Can I drink coffee and alcohol on a low-FODMAP diet?

Black coffee and espresso are low-FODMAP in normal serving sizes. For alcohol, beer, dry red and white wine, gin, vodka, and whiskey are typically tolerated; rum, sweet wines, and most cocktails (especially anything with apple, pear, or agave) are not. Hydrate well — IBS symptoms often worsen with dehydration.

Will I lose weight on a low-FODMAP meal plan?

Weight change isn't the goal. Some people lose a few pounds simply because they're eating fewer processed foods and less bloating volume; others gain because lactose-free dairy and gluten-free baked goods can be calorie-dense. If weight management matters, pair the protocol with calorie tracking — MealFrame's barcode and photo scanner makes it effortless.

What can I eat at restaurants on a low-FODMAP diet?

Look for grilled proteins, plain rice, baked potatoes, and salads with oil and vinegar. Ask for sauces on the side and request no garlic, no onion — most kitchens can accommodate it. Asian, Mexican, and Mediterranean cuisines often have more naturally low-FODMAP options than they get credit for.

The takeaway

A well-built low-FODMAP meal plan can quiet IBS symptoms within two weeks — but only if you actually follow it consistently. Use this 7-day plan as your starting point, work with a registered dietitian for the reintroduction phase, and lean on tools that handle the planning, portioning, and grocery logistics for you.

If you're tired of staring at the Monash app at 9 p.m. trying to figure out what's safe for tomorrow's lunch, MealFrame builds your entire low-FODMAP week in seconds — gut-friendly, nutritionally balanced, and tailored to whatever else you're juggling (calorie targets, gluten-free, dairy-free, family-friendly meals). Your gut shouldn't have to negotiate with your calendar.
