I am not a doctor, dietitian, or registered nutritionist. I want to be upfront about that from the first paragraph, because what I write is grounded in something different: years of personal experience, careful self-education, and a deep frustration with how overwhelming the world of gut health advice has become.
"I spent the better part of three years reading, testing, and quietly observing — trying to understand why simple meals left me feeling so uncomfortable. What I found was that the most useful changes weren't complicated. They were about paying attention."
How this guide came to exist
Like a lot of people in their 30s and 40s, I started noticing changes in how I felt after eating. Nothing dramatic — just a persistent heaviness, an unpredictability that hadn't been there before. I went looking for answers and found an overwhelming amount of conflicting information: elimination diets, probiotic protocols, gut microbiome deep-dives, expensive supplement stacks.
Most of it was either too clinical for everyday life or too vague to be useful. I couldn't find a simple, realistic starting point that didn't either make medical promises it couldn't keep or require a complete overhaul of how I ate.
So I built my own. Over 18 months, I tested a food-first approach — keeping a diary, tracking patterns, simplifying my meals, and gradually reintroducing foods to see what my body responded to. I interviewed practitioners, read peer-reviewed research, and spoke to friends who were navigating similar experiences.
The 21-Day Gut Reset is the structured version of that process. It is not a miracle. It is a starting point — practical, realistic, and honest about what it can and cannot do.
My approach to writing about gut health
Digestive health is a YMYL topic — it matters to people's lives, and writing about it irresponsibly can cause real harm. I hold myself to a clear set of principles:
- 🔍 I cite primary sources where possible and link to them in my articles. I don't make claims I can't support.
- 🚫 I don't use words like "cure", "treat", "heal", or "reverse" in connection with any digestive condition. These are medical claims, and I am not in a position to make them.
- 👩⚕️ I always include guidance to seek professional help when appropriate — especially for persistent, worsening, or complex symptoms.
- 🤝 I write from lived experience and documented research. I don't simulate expertise I don't have.
- ✏️ I update my content when new evidence emerges or guidance changes.
A note on credentials
Wellness writing is an unregulated space, and I think readers deserve transparency. I hold no clinical qualifications. My authority on this topic comes from four years of careful personal research, extensive reading of peer-reviewed literature, conversations with practitioners, and documented personal experience.
If you have a diagnosed digestive condition — IBS, Crohn's, coeliac disease, or anything else managed by a specialist — please treat this guide as supplementary reading, not a substitute for professional care. Chapter 10 of the guide includes specific guidance on when to seek help.
Where to find me
I publish articles on digestive wellness, food-first approaches, and practical nutrition habits on the Gut Reset 21 blog. If you have questions about the guide or want to get in touch, the best way is via the Contact page.
