The LECTIN-FREE MENTORING Program
Next Start: September 2026
Your journey to more well-being begins with the right guidance
Have you already tried numerous diets, but your symptoms persist? Are you struggling with digestive problems, chronic inflammation, autoimmune diseases, or intolerances and looking for a sustainable approach instead of the next short-term diet?
The LECTIN-FREE Mentoring will intensively accompany you for three months on your journey to more health, energy, and quality of life. Together with Tobias and Karin, you will receive sound knowledge, personal support, and a clear roadmap for implementation in everyday life.
For people who want to achieve real change
Our mentoring is based on the principles of a lectin-free diet, targeted support for gut health, and sustainable lifestyle optimization. The focus is not on perfection, but on a long-term implementable change.
Do you know that?
You receive a diagnosis – and suddenly these limitations are there:
The medications.
Renunciation.
The fear.
You identify with your diagnosis and say "I have migraines" or "I have rheumatism" and go from doctor to doctor.
You'll put up with it for a while.
And then at some point this one question arises:
"Is that it?"
What awaits you in the LEKTINFREI Mentoring

Scientifically Sound & Practical

Karin & Tobias
Tobias is "the knowledge" and knows about autoimmune diseases not only from books, but also from personal experience. He himself went through an intense health crisis – and from this experience developed an approach that combines science, everyday life, and enjoyment.
Karin is "happiness" and She was Tobias's most important support during his illness. Through her intensive work with mindset, affirmation, and spirituality, she kept Tobias grounded before he got too lost in the science.

"Tobias and Karin possess incredible knowledge in this field."
I switched to a lectin-free diet in September 2025 – and all I can say is: I'm thrilled!
Before that, fatigue and iron deficiency heavily burdened me, and regular iron infusions were part of my daily life. By switching to a lectin-free diet, I can now live completely without infusions and finally feel energetic and stable again.
Tobias and Karin possess incredible knowledge in this field and support me in every way – empathetically, competently, and always honestly. You immediately notice how much the well-being of people means to them.
Thank you both so much for sharing your knowledge with such dedication and offering a real alternative to so many people. You are great!

"From the very beginning, I felt extremely well supported."
Due to my chronic illness, I became aware of the lectin-free diet and Tobio's mentoring program. From the very beginning, I felt extremely well supported. Tobias is simply an expert in this field and combines enormous expertise with great empathy. My diet was individually tailored to me and my condition, and the practical tips for everyday life have noticeably helped me. I am very grateful for this support and can wholeheartedly recommend the consultation.

"And what can I say, that was my absolute game changer."
Hello, today I want to say thank you to Karin and Tobias 🙏🏻 When I was at the worst of my digestive problems, I had a wonderful Zoom call with them! And Tobias explained in detail how I should do things to feel better again!!! And what can I say, it was an absolute game changer for me. After just three weeks of following their tips, I was already feeling significantly better, and all without medication or supplements!!! Simply with their fantastic way of eating—specifically, the lectin-free diet!!! The flour mixes and the book "Soul Hunger" make it very easy to change your diet. I wholeheartedly recommend everyone try it!!!! My sincere thanks to Karin and Tobias; I'm so glad you're there 🙏🏻❤️

"I am very grateful for this support and the new insights."
I had a consultation with Tobias and Karin Stumpfl about a lectin-free diet – and I can honestly say: this encounter was life-changing for me. It was particularly valuable to truly understand the connections between my diet, my body, and my inflammation levels. I realized that for decades I had been eating precisely those foods that were anything but beneficial for my health – without even being aware of it. The consultation was not only informative but also very empathetic and personalized. You feel seen, taken seriously, and expertly guided. Of course, I took the accompanying cookbook with me – and what can I say? To my great delight, I discovered that the very foods that now taste better to me are also significantly better for my body. A real eye-opener! I am very grateful for this support and the new insights. I wholeheartedly recommend that everyone explore nutrition and its effects on their own body – and trust in people who provide guidance with as much knowledge, heart, and dedication as Tobias and Karin.
