You’ve been told it’s “just IBS” and given a printout.
You’ve had the tests. The bloodwork. Maybe a colonoscopy. The results came back “normal.” And yet every meal still ends in bloating, cramps, urgency or exhaustion.
You shouldn’t have to plan your day around a toilet, or eat 10 foods on rotation just to feel okay.
- ×Bloating that gets worse through the day, no matter what you eat.
- ×Constipation, diarrhoea, or both - sometimes in the same week.
- ×Reflux, wind, abdominal pain that flares without warning.
- ×Trying yet another elimination diet found on Instagram and feeling worse.
- ×Low energy, brain fog, and mood dips you can’t quite explain.
- ×Avoiding social meals because you don’t trust your body.
The same step-by-step protocol used in Gillian’s clinic · now self-paced.
Twelve clinically-structured modules. A guided elimination and reintroduction phase. Recipes, shopping lists, and the FODMAP framework Gillian trained in at Guy’s & St Thomas’. No guesswork, no Instagram trends, just the protocol that has resolved gut symptoms for over 1,000 clients.
How your gut actually works and why “normal” tests can still mean something is wrong.
Identify exactly what your symptoms are telling you, so you stop guessing the cause.
A 6-week low-FODMAP elimination phase - with most people feeling better within the first 10 days.
A library of dietitian-built recipes, plus printable supermarket-aisle shopping lists.
Learn how to safely test trigger foods without losing the progress you’ve made.
Build your personalised long-term food list based on what actually works for your body.
Why food alone isn’t always the answer, and what to do about it.
The exact approach for restaurants, weddings, holidays and everyday social eating.
Step out of restriction and into a sustainable, varied, gut-friendly way of eating.
What you’ll feel, usually within 10 days.
Most clients see meaningful symptom reduction inside two weeks. Here’s what they tell us has changed by the end of the course.
A flatter, calmer stomach
Most bloating, wind and visible distension settles within the first 10 days as the elimination phase removes your specific triggers.
Predictable bowel movements
No more sprinting for the loo. Regularity returns once the irritation does, and you’ll understand why it was happening.
Energy, mood, mental clarity
The gut-brain axis is real. Fix the gut and most clients report sharper focus, better sleep and a lift in mood within weeks.
A list of foods you can trust
By the end, you’ll know exactly which foods are your triggers and which you’ve been needlessly avoiding for years.

People who’d tried everything · and finally found relief.
I have been working with Gillian for some months now and have found her knowledge and expertise invaluable in helping me address my health and weight issues. She has provided me with all the information, plan and recipes to move forward in making the changes I need to improve my wellbeing. Any questions I had along the way Gillian always gave a prompt response. I would highly recommend working with Gillian to anyone who is trying to navigate a path to overcoming any health related problems.
A very valuable experience which I would highly recommend — transformative outcome that far exceeds any consultations I've had to date with doctors. Gillian is a true professional and should be people's first port of call prior to going down the traditional medical route. My consultation with Gillian has been an education and has shown me that I have the ability and power to determine my own health through following her recommended course of action.
Brilliant service offered by Gillian. Gillian is positive, empathetic and understanding. The programme was comprehensive and I felt supported throughout as the changes can be overwhelming. The results have been great and I have taken away Gillian's knowledge which I can continue to apply to manage my symptoms. Highly recommend!

Honest answers, before you buy.
The full course is 3 months end-to-end, including the elimination phase, reintroduction, and building your long-term plan. Most people experience meaningful symptom relief within the first 10 days, and the rest of the time is staying symptom free and then identifying your specific triggers and building a sustainable forever plan.
Yes, and that’s the most common scenario we see. Most people who try low-FODMAP from a leaflet or a Google search get the elimination phase wrong, skip the reintroduction phase entirely, or end up over-restricted. Gillian’s protocol is the full clinical version, with the reintroduction phase that 90% of self-directed attempts miss.
None. You need internet access for the videos and a kitchen. Supermarket ingredients only. No bizarre powders, no expensive supplements. Everything is tested in normal UK and Irish supermarkets.
The course is designed primarily for IBS, functional gut symptoms, bloating, reflux and SIBO. If you have a new diagnosis of a condition like Crohn’s, ulcerative colitis or coeliac disease, we recommend the 1-1 programme with Gillian instead. Book a consultation through the portal and we’ll guide you to the right option.
The protocol is structured but not rigid. The course teaches you the principles so you can apply them around real life - restaurants, weddings, busy weeks. Module 8 is dedicated to exactly this. Lifetime access means you can revisit any module whenever you need a refresher.
The course is designed primarily for UK and Irish supermarkets, but the protocol works anywhere. Recipes are easily adaptable and most ingredients are common globally. We have students in Australia, Canada and the US.
