Fix gut issues & increase energy levels without long term restrictive diets

If you’ve been doing all the things and you’re still stuck, you’re not failing.

You’re probably working on the wrong layer.

The pattern I see most often in clinic looks the same. Someone arrives having tried three probiotics, two elimination diets, a stool test, and a shelf of supplements.

They’re tired, they’re frustrated, and the food list keeps shrinking. The bloating hasn’t shifted.

When we sit down and walk through it, the issue is almost never that they haven’t tried hard enough. It’s that the protocol they were following was working downstream the whole time. Microbiome, food cuts, supplements. None of which were ever going to land while the stages above were stuck.

How you eat. Stomach acid. Motility. Bile. The nervous system underneath all of it.

You don’t need more discipline. You need a better order.

If you want to talk it through, the discovery call link is in my bio.

Most gut protocols start at the wrong end.

A probiotic. A food cut. Six months on low FODMAP. And somehow you’re still bloated, still uncomfortable, still adding things to the “I can’t eat that” list. The reason it isn’t working is rarely effort. It’s order.

Digestion is a sequence. Five stages, each one depending on the one before it. Your mouth and brain. Your stomach. Your small intestine. Your large intestine. And the nervous system running underneath all of it.

Most plans work on stage four. The microbiome. Probiotics, prebiotics, fermented foods. None of which land properly if the three stages above them are stuck.
In clinic, this is the bit I see people skip. They jump straight to the microbiome and wonder why they’re still bloated a year later.

The cheapest, most impactful work is almost always at the top of the cascade. How you’re eating. Your stomach acid. Your motility. None of which require a supplement.

Save this for later. Part 1 of a 5-part series on gut health. Part 2 next week takes us into the top of the tract in detail.

Most gut health plans start at the wrong end.

A probiotic. A food cut. A six-month low FODMAP stint. And somehow you’re still bloated, still uncomfortable, still anxious about every meal.

The reason isn’t that you’ve failed. It’s that digestion is a sequence. Mouth, stomach, small intestine, large intestine, nervous system underneath all of it. Each stage depends on the last one working.

You can’t out-probiotic a sluggish motility system. You can’t out-restrict a stomach that isn’t producing enough acid. You can’t fix the microbiome by ignoring the four stages above it.

This is part one of a five-part series. Over the next five weeks I’m walking through the whole tract, top to bottom, so you can actually see where things go wrong and what to do about it.

Save this. Follow for part two next week.

Most people think SIBO means diarrhoea.

There’s a version that does the opposite. It’s called IMO.

The organisms involved produce methane. Methane slows gut motility.

The pattern in clinic: chronic constipation, bloating that builds through the day, fibre making things worse, laxatives losing their effect.

Most gut damage doesn’t come from a single food. It comes from the slow stack of factors above.

Save this for yourself and send it to the friend who’s cut out half their diet and still feels bloated.

Most people who come to me have already cut out gluten, dairy, sometimes both. they’ve tried low fodmap. they’re on their third probiotic. And they’re still bloated.

Here’s what’s often missing from the conversation:

Digestion starts in the mouth. when you eat fast, food arrives in your stomach in large pieces, your digestive system can’t keep up, and the bacteria further down get a feast they shouldn’t get.

Before you cut another food, try this. pick one meal a day. put your fork down between bites. fifteen to twenty minutes minimum. give it a week.

It’s the simplest thing i ask clients to do, and it’s often the most surprising.

Comment SLOW and I’ll send you a list of my favourite digestion tips.

Understanding leaky gut is one thing. Knowing what to actually do about it is another.

Here’s the framework I use with clients.

First - identify the drivers. Dysbiosis, SIBO, chronic stress, alcohol, regular NSAID use. You can’t support a permeable gut lining without understanding what’s making it permeable.

Second - reduce the active disruptors. This might involve working with your GP, dietary changes, or treating the stress response as a physiological input rather than just a lifestyle factor.

Third - rebuild the conditions for gut lining integrity. Fibre diversity for butyrate production, addressing microbial imbalances, supporting the mucus layer.

Fourth - test where appropriate. A comprehensive stool test gives you a real map of what’s happening. Guessing is slower and more expensive in the long run.
Fifth - allow time. The gut lining renews relatively quickly, but the underlying drivers don’t shift overnight.

This is the kind of structured approach I take in practice. If you’re not sure where to start with your own symptoms, a discovery call is a good first step.

Intestinal permeability doesn’t happen randomly.

There are well-researched factors that affect how well your gut lining does its job - and some of them are probably more familiar than you’d expect.

Chronic stress affects the proteins that hold your gut lining together. The gut-brain axis has real, measurable effects on barrier function.

Regular NSAID use - ibuprofen, naproxen, aspirin - is one of the most documented disruptors of gut barrier integrity, particularly in the small intestine.

Alcohol affects gut permeability even at moderate regular levels. This is some of the most established research in this area.

Low fibre intake reduces production of butyrate - the short-chain fatty acid that fuels the cells lining your colon. Less fibre, less butyrate, less structural support for the gut lining.

These aren’t obscure or rare exposures. They’re part of everyday life for a lot of people.

Which is why addressing gut permeability is rarely about one supplement. It’s about identifying what’s driving it in your case.

“Leaky gut” is one of the most searched - and most misunderstood - terms in gut health.

Here’s what the science actually says, without the hype.

Save this for the next time someone asks you whether it’s real.

Leaky gut gets talked about like it’s either the answer to everything or complete nonsense.

Neither is quite right.

Intestinal permeability - the clinical term - is well-documented science. Your gut lining is one cell thick, held together by proteins called tight junctions.

When those tight junctions stop working properly, permeability increases. Bacterial fragments and food proteins can cross into areas they shouldn’t, and your immune system responds.

That process is real.

What’s overclaimed is the idea that it explains all chronic illness, or that a single supplement fixes it.

The research links increased permeability to conditions like IBS, coeliac disease and Crohn’s - but we’re still working out what drives what.

If you’ve been confused about leaky gut, you’re not wrong to be. The way it gets presented online is genuinely misleading.

More on what actually affects your gut lining this week.
