Low FODMAP Meal Plan: 7 Days, Fully Costed and Macro-Tracked
This plan covers the elimination phase of the low FODMAP diet — the 2–6 week diagnostic window where you remove high-FODMAP foods to see whether they drive your symptoms. It is not a long-term diet, and it is not a weight-loss diet.
⚠️ Medical disclaimer: Exclude coeliac disease before removing wheat. Work with a dietitian where possible; reintroduction quality determines whether this exercise is worth doing.
Key takeaways
Each day lands around 1,900–2,100 kcal with 100–130 g protein — adjust portions to your own targets.
Garlic-infused oil and the green tops of spring onions replace the two hardest ingredients to give up.
Batch-cook on day 1 and day 4; the plan reuses components deliberately.
Keep servings within Monash-tested limits — many foods are low FODMAP only up to a specific portion size.
Sunday: cook 600 g rice, roast 1 kg potatoes, make garlic-infused oil stock base for the soup.
Wednesday: cook quinoa, prep salad vegetables, portion snacks into containers.
Batching is not optional for adherence — the most common failure point in elimination diets is a hungry weekday evening with nothing prepared.
6. Safe swaps and flavour rules
Instead of
Use
Garlic
Garlic-infused oil
Onion
Green tops of spring onion, chives, asafoetida (tiny pinch)
Wheat pasta
Rice, corn or quinoa pasta
Milk
Lactose-free milk, almond milk (250 ml max)
Honey
Maple syrup
Stock cubes
Low-FODMAP stock or homemade with carrot, celery leaf, herbs
Apple/pear
Orange, kiwifruit, firm banana, berries
Fructans and GOS are water-soluble, not oil-soluble — this is exactly why infused oils work and why draining and rinsing canned lentils reduces (but does not eliminate) their GOS load.
Follow this plan inside Nutrtion.io — photograph each meal and it auto-tracks macros while flagging any ingredient that would break the elimination phase, so week 6 gives you a clean answer.
FAQ
How long should I stay on the elimination phase?
Two to six weeks. If you have no improvement by six weeks, FODMAPs are not your trigger.
Will I lose weight on this plan?
It is designed to be weight-neutral around 2,000 kcal. Unintentional weight loss on low FODMAP usually signals under-eating from restricted choices.
Can I drink coffee?
Black coffee and espresso are low FODMAP. Caffeine itself may still trigger urgency in IBS-D.
Is this plan vegetarian-friendly?
It can be, but legumes are the main plant protein and are GOS-rich. Use firm tofu, tempeh, eggs, canned lentils (rinsed, 1/4 cup) and quinoa.
What about alcohol?
Beer, wine and spirits are low FODMAP in standard serves, but alcohol independently irritates the gut. Minimise during elimination.
