About Mark Carlson

“Food has nothing to do with it.”

Those were the words my gastroenterologist used after I described my latest dietary experiment with real optimism. She said it kindly, almost as if reciting a line she had delivered many times.

“Food has nothing to do with it. You have Crohn’s disease.”

The arc

How I got here

By then I had spent years rotating through medications and watching my world shrink around bathroom access and flare forecasts. Surgery was part of the script. So was increased cancer risk. I was still in my thirties, being told that the best realistic outcome was “management.”

That night, standing in my kitchen, I opened the refrigerator. The door was packed with boxes of preloaded syringes: another “promising” drug that looked eerily like the three regimens before it. For a moment, I could see the rest of my life as a series of trials.

It was not a dramatic moment. It was a quiet calculation.

If I stayed on the same track, I knew roughly where I would end up. They had already told me. If I stepped off it and treated my body as the primary source of evidence, at least I would be accountable to reality instead of a protocol.

Then there was the other path.

I went all in on understanding what could actually change the conditions surrounding my disease. I learned how immune activity, gut-barrier function, food response, and the conditions in which I ate and lived could interact. For the first time, the pieces began to form a coherent picture.

Some foods aggravated the system; others gave it room to heal. The conditions of eating mattered too. So did stress, sleep, pace, and the state my body was in when food arrived.

I experimented carefully, tracked what changed, and stopped accepting explanations that could not account for what I was actually observing.

Within months, surgery was off the schedule. Two years later, I was no longer taking GI medication.

I am now in my fifties, still in clinical remission.

Still driven to understand the mind, body, and gut as one connected system.

This history is not a promise that your case will match mine. It is the reason this practice exists. I learned the hard way that neither conventional medicine nor alternative hype had a monopoly on truth.

What I needed was a way that respected my physiology, helped me investigate the underlying drivers, and put me back in charge of my decisions. What I found was a way to think about health from the ground up.

I did not get well by finding the perfect protocol. I got well by learning how to read the system.

The work is to connect what happened, what you feel, what the labs show, and what changes when the right question is tested. The understanding stays with you.

The work in practice

There are the lab results, what the gut is being asked to handle, and what’s not being said.

The practice

What I do now

I am a Functional Diagnostic Nutrition Practitioner and a Board Certified Natural Wellness Practitioner. But the expert this work is built to produce is you. Health already has plenty of experts telling people what to do from the outside; what changed my case was becoming fluent in my own. So the reasoning here stays visible: you know what we are investigating, why a test belongs, and what the result changes.

Digestive Recovery, the practice’s one program, is that method applied to chronic and complicated gut symptoms over three to four months.

The win condition is strange for a business, but it is the one I care about: you stop needing me, and you know why each thing worked.

Where the thinking lives

The framework behind this practice is worked out in public, in writing, at Health Under Control. If you are the kind of person who wants to audit the reasoning before trusting the practitioner, that is exactly what it is for.

Read it skeptically.

I was skeptical. I had already done a lot of work. But I have to say that if I eat crappy food now, it’s a choice vs feeling a pull to use food as a device. And if my paperwork starts piling up, I just do it without much negative thought!”
