About Matt
Dietitian Nutritionist based in Lyon, France, working remotely with clients worldwide.
Most of my clients come to me after years of searching for answers. They understand their conditions, they’ve done the research, and they want a practitioner who will engage with their complexity. This practice exists for them.
Matt Had Two Decades of Chronic Illness
Matt Cress is a Dietitian Nutritionist who spent over two decades living with chronic health conditions before nutrition changed everything. Twenty-five years of severe allergies. Ten years of cystic acne. IBS that went unrecognized for most of his life.
That experience shapes how he works. Matt approaches every client with the full picture in mind, not just the symptom in front of him. His background in chemistry gave him a mechanism-first way of thinking: he wants to understand why something is happening before deciding what to do about it.
Based in Lyon, France, Matt brings both American nutrition training and European food culture into his practice. He goes to the farmers market every week, ferments his own foods, and has been a competitive artistic gymnast for nearly three decades.
How I Work
Physiology First
Every plan starts with your digestive capacity: stomach acid, bile flow, enzyme activity, and motility. The goal is to fix the cause, not only quiet the symptoms.
Whole Food, Whole Person
Real food over supplements wherever possible, traditional food knowledge alongside current research, and your relationship with eating as part of the clinical picture.
Complex Cases Welcome
Many clients arrive after being told their case is too complicated to explain. Complex health conditions are the focus of my practice.
Work with Matt
Private 1-on-1 care starts at $300 (€270).

What makes this practice different
Physiology first
Every protocol starts with understanding your digestive capacity: stomach acid, bile flow, enzyme activity, motility, before adding anything else. Symptoms are signals, not targets.
Whole food, whole person
Real food over supplements wherever possible. Traditional food wisdom alongside modern research. And always, the psychological relationship with eating as part of the clinical picture.
Complexity is welcome
Many clients arrive having been told their case is too complicated or too hard to explain. That’s not a problem here. Complex presentations are where this work begins.
