You've tried everything. A balanced diet for chronic fatigue management. Supplements. Maybe even worked with other practitioners who ran expensive tests and gave you protocols that didn't help.
Here's what they missed.
Your body is desperately trying to keep you alive. When it encounters things it can't process (the undesirable effects of MRI contrast like gadolinium retention, environmental toxins, even compounds from foods, like oxalates), it goes into emergency mode.
Think of it like this: your house is flooding, so you start shoving towels under the door. It stops the immediate crisis, but now you're out of towels and the water is still rising. Your body does the same thing. It creates emergency responses that save you in the short term but cost you dearly later.
Meanwhile, your mitochondria (the power plants in every cell) start failing. Your metabolism gets scrambled. Your immune system goes haywire. Understanding how to support mitochondrial health becomes critical, but most practitioners don't know where to look.
Modern medicine sees your symptoms and tries to suppress them. Antidepressants for the anxiety. NSAIDs for the pain. PPIs for the digestion. Each one interfering with your body's desperate attempts to fix the actual problem.
The opportunities to address what's really wrong get missed. Damage accumulates. Your body spreads the strain across more and more systems until you're stretched thinner than Oliver Twist's watery gruel.
They're emergency rescue operations—your body fighting to keep you alive using whatever molecules it can recruit. The problem? Your doctors are reading the rescue as the crime.
This 6.5-minute video explains the ATTRACT framework: the biological cascade that conventional medicine systematically misses.
No wellness fluff. No pseudoscience. Just the mechanism.

That's the cascade. Contamination → Salvation → Communication → Damnation. Now let's find yours.
Now you understand the mechanism.
Ready to identify what's driving YOUR specific cascade?
Every person's toxic burden, metabolic breaking points, and rescue operations are different. The video shows you the framework. A comprehensive health assessment shows you your map.
In 90 minutes, we'll review:
Your complete health history
Pattern analysis using the ATTRACT framework
Preliminary identification of your cascade triggers

I'm a Cambridge-trained physician who spent years as a consultant paediatrician. I thought I understood health.
Then I got poisoned by gadolinium during a routine medical scan. I experienced firsthand the long-term effects of MRI contrast and the risks of MRI contrast dye injection that the medical establishment insists don't exist.
I also have Ehlers-Danlos Syndrome with hypermobility. I've lived through years of symptoms that doctors dismissed or couldn't explain. Understanding EDS hypermobility and exploring Ehlers-Danlos treatment options became a matter of survival.
I had to figure out what was actually happening at the cellular level because my career and my survival depended on it.
That journey led me to develop new frameworks for understanding how bodies break down under toxic burden and metabolic strain. I wrote the book on the risks of MRI contrast dye and the negative impact of MRI contrasting agents (literally: Contrasts: More than meets the MRI). I co-authored the largest patient-led research study on gadolinium toxicity symptoms treatment. I work with leading researchers and patient advocacy groups.
I've been on Sky News, in the Daily Mail, on BBC Radio Ulster. I've appeared on podcasts explaining what the medical system refuses to acknowledge.
But more importantly, I've helped countless people recover when everyone else had given up on them.
I see patterns other practitioners miss because I'm looking at the actual physics and chemistry of what's gone wrong, not just symptoms on a checklist.
“For anyone affected by gadolinium… she is able to offer far more holistic and effective changes to aid your recovery than any traditional western doctor will.”
Mike O'Connor
“I would highly recommend Catriona’s service… She explains the science behind all your nutrition needs which can be overwhelming but gives you full faith in the fact that she knows what she is talking about.”
Kerry Muldowney
“I can really say my life is worth living again now, after suffering for three years… I didn’t really believe in such positive changes anymore.”
Maria Gröbl
“Even as a nurse, I hadn’t appreciated the extent food can heal… Within 6 weeks, I couldn’t believe the recovery. It was nothing short of miraculous.”
Claire McGuigan
“Catriona also helped me believe in my gut instincts when I felt a food was upsetting me… Catriona gave me the confidence to do this.”
Caoimhe Porter
“I now feel my future health can be determined by my own eating habits…a great relief having never been able to get any long term solutions despite numerous doctors investigations.”
Stephen Heaney
Let me address something that trips up a lot of people.
Many people turn to "healthy" plant-based diets. Green smoothies packed with spinach and kale. Almond butter. Sweet potatoes. All the superfoods Instagram told you would heal you.
You got worse. Maybe you're now handling oxalate dumping reactions, dealing with oxalate detox symptoms you didn't even know were possible.
Here's why. When your body is already overwhelmed, high-oxalate plants add to your burden. Finding help for oxalate dumping symptoms is difficult because most practitioners don't understand the connection. When your mitochondria aren't working properly, you can't process certain plant compounds. When your gut is compromised, those "anti-inflammatory" foods trigger more inflammation.
The problem isn't that plants are all evil. The problem is that one-size-fits-all dietary advice ignores what's actually happening in your specific body right now.
And let's be honest about something else. Modern dietary guidelines are a recent experiment with disastrous results. Before the early twentieth century, nobody ate what we now consider normal. We've been told that fat, cholesterol, and salt are trying to kill us, based on poor-quality observational studies that are often contradicted by other studies.
Meanwhile, the ultra-processed food industry created chemical aberrations masquerading as food. They spent billions figuring out how to replicate the taste, smell, and mouthfeel of actual nutrition while delivering none of it. And they succeeded in creating food substitutes that are hyperpalatable and addictive.
That's the real fad diet. What I teach through ancestral diet benefits and holistic living lifestyle tips is what human bodies actually evolved to eat.
No, you can't have your cake and eat it too. But after a couple of weeks off the hyper-palatable junk, something interesting happens. Your taste buds wake up. You realize they'd been buried under layers of sugar and additives. Real food starts tasting like something again.
I'm not here to hand you a protocol. I'm here to figure out what's actually wrong with you specifically.
We do a deep investigation into your health history, your symptoms, your diet, your exposures. If you have functional test results (like organic acids tests), I can help you interpret them through frameworks most practitioners don't understand.
We figure out:
What toxic burdens you're carrying
Why your mitochondria are struggling and which foods to support mitochondria
Which foods are helping versus hurting (including natural remedies for mitochondrial issues)
What your body actually needs to recover, often through an optimal animal-based diet for wellness that provides nutrient-rich support
Which foods are helping versus hurting (including natural remedies for mitochondrial issues)
Why your mitochondria are struggling and which foods to support mitochondria
I use professional nutrition analysis software (Nutritics, not consumer apps) to show you exactly where your nutritional gaps are. Yes, it often reveals why you should eat liver. I encourage animal-based nutrition and wellness principles, and I eat this way myself. If you absolutely can't, we'll find alternatives. No diet police will be sent out to check up on you. But it's worth trying some delicious lamb's liver before you decide, even if you have to hide it.
This is collaborative. You know your body better than anyone. I know the biochemistry and the patterns. Together we figure it out.
A deep, personalised dive into your unique health story. While functional tests aren’t required, I can help you decipher any results you already have (like urine OATs) through the lens of my ATTRACT Theory to create a bespoke plan to get your life back.

Practical techniques for when everything feels overwhelming.
The deep dive into gadolinium toxicity from someone who lived it and researched it. While I've learned even more since writing it (oxalates weren't on my radar yet), it's still the starting point.
The largest patient-led study. Real data, real stories, real support. Written by patients.
What we eat now is the experiment. Before the early twentieth century, humans ate actual food. What I teach through the lens of an ancestral diet isn't restriction, it's a return to what bodies need.
And no, you can't keep eating processed garbage and expect to feel better. But your taste buds will recover faster than you think.
I don't. I've tried. Checked what the experts said, attempted workarounds. For the complex cases I see, it doesn't work. People who thrive long-term without animal products usually started out healthy. You're not there yet. And oxalates don't like you. Plant proteins are full of them. Trust me on this.
I don’t arrange testing myself, but if you have results from tests like urinary organic acids (OATs), I’m more than happy to run through them with you and explain what they mean through the lens of my clinical experience. Most practitioners miss what the tests are actually showing.
Many people feel improvements within days or weeks—those are the lucky ducks. They still work hard to make their own luck, but they may have won the detox genetics lottery. For more complex clients, it can sometimes take six months to really see the dial start to move. I also see a pattern of greater struggles in those taking psychotropic medications, which can be remarkably toxic to your metabolism. Coming off them is a monumental challenge, and you have my deepest sympathies if you’re stuck in that damned-if-you-do, damned-if-you-don’t situation.
A collection of thoughts, investigations, and inconvenient truths. Consider this your field guide to a broken system.
I left conventional medicine because I couldn't keep participating in a system that ignores what's actually making people sick. That decision cost me. But authenticity was the only option. The support I received when I was at my worst was everything. Now I want to offer that to you. If you're lost, unheard, or betrayed by the system that was supposed to help you, let's talk.
