You're looking for the low FODMAP food list - the actual "eat this, not that" version. 

Good instinct. It's one of the most genuinely useful tools in gut health, and it's right below.

But after 15,000+ clients, there's something dietitian Joe Leech tells everyone before he hands it over.

If you've been dealing with bloating, unpredictable bowels, or stomach pain for months - maybe years - the list is going to help. A lot of people feel real relief within the first couple of weeks. 

But if this isn't your first attempt at fixing this, you may have noticed something before: relief that shows up, then plateaus, or quietly creeps back once life gets in the way.

That's not a sign you did the list wrong. It's a sign the list was only ever step one.

What the list actually does well - and where it stops

The low FODMAP list works by removing a specific category of fermentable carbohydrates that trigger symptoms in a lot of people. 

For many, that alone brings real, fast relief - which is exactly why it's worth doing, and why it's below.

Here's what it doesn't do: identify why your gut reacts to those carbohydrates in the first place. 

A follow-up study of patients using the diet found 86% reported meaningful improvement - but only about a third said their symptoms fully resolved; more than half described the result as partial.¹ 

That gap is the room the list can't close on its own, because it manages symptoms without addressing what's actually causing them.

The short version of why

Picture your gut like a garden. 

If weeds are choking out the flowers, you don't grab a bag of fertilizer and throw it over everything - that just feeds the weeds. You clear them first, then replant and feed.
For a lot of people with stubborn symptoms, the underlying issue works the same way: it's not a shortage of "good" gut bacteria, it's an overgrowth of bacteria or other microorganisms that shouldn't be there in that quantity. 

The FODMAP list works partly by starving that overgrowth of some of its favorite fuel - which is exactly why it helps. But it doesn't identify what's actually overgrown, and it doesn't clear it.

That's the piece almost nobody explains: managing symptoms and clearing the root cause are two different jobs. The list was only ever built to do the first one.

Who's behind this

Joe Leech (MSc) has practiced as a dietitian since 2011, specializing in gut health. He started writing about digestive health in 2014, and his work eventually reached close to a million readers a month. 

Since then, he has been featured in TV and documentary series, and his team of specialist gastrointestinal dietitians has worked directly with more than 15,000 clients - earning a 4.8-out-of-5 rating on Trustpilot.²
One longtime client wrote that she's now able to go on 20-mile bike rides - something she says she wouldn't have dreamed of doing during the sixteen years her gut issues went unaddressed. As with any health outcome, individual results vary.
Summary: FODMAPs exist mainly in dairy, legumes, and many fruits and vegetables. While gluten is not technically a FODMAP, gluten-free products are typically lower in FODMAPs anyway.

Step one is below. Here's what steps two through four look like

The list you're about to get is step one: manage symptoms, starting today. 

Steps two through four - identifying what's actually overgrown, clearing it, and rebuilding so food stops feeling like a risk - are what Joe's short training walks through, in three parts, over your inbox this week.
