The Mind Body Biome™ Method
My signature gut health programme: a trauma-informed, science-backed approach for people who’ve “tried everything” and still don’t feel better.
Healing Your Gut Begins With Understanding Your Body - and Your Story
Does This Sound Familiar?
Your symptoms shift with stress - and no amount of food rules or supplements creates lasting change.
You feel stuck in a cycle of tension, overwhelm, or burnout that your gut seems to react to.
You’ve tried focusing on diet alone, but deep down you sense there’s more going on beneath the surface.
If so, you’re not alone - and you’re not doing anything wrong.
I’ve supported hundreds of people who felt confused, dismissed, or stuck in a cycle that felt impossible to break. Your body isn’t failing you - it’s responding to stress, history, and patterns you’ve carried for a long time, in ways that make sense once we look at the full picture.
My Mind Body Biome™ approach combines gut support, mind–body work, and functional understanding to help you uncover what’s really driving your symptoms. Together, we create change that feels supportive, safe, and sustainable - not overwhelming or restrictive.
Imagine If…
You woke up feeling grounded and at ease in your body - not anticipating discomfort, tension, or bloating.
You knew exactly what nourishes your gut, without second-guessing or restricting yourself.
You could enjoy food and social occasions with ease, moving through your day with more energy and emotional stability - instead of your gut dictating everything.
You had a more regulated nervous system - more ease, more softness, more space to breathe.
All of this becomes possible when we work with your mind, your body, and your microbiome together.
Through the Mind Body Biome™ approach, we uncover what’s really driving your symptoms and create a personalised, compassionate plan that supports you on every level.
Why The Mind Body Biome™ Method Works When Other Approaches Don’t
Chronic gut symptoms rarely heal through restrictive diets, random supplements, or medication alone. They’re shaped by your biology, your stress patterns, your microbiome, and the experiences your body has held over time.
Your gut doesn’t heal in isolation - it is connected to every other system, especially the nervous, immune and hormonal systems.
Because the gut and brain communicate constantly, unresolved stress patterns and emotional tension can act as hidden drivers of chronic digestive symptoms.
My Mind Body Biome™ approach, shaped by almost a decade of experience, reflects the most effective way I’ve found to support people with long-standing gut issues. I look at the whole picture - nutrition, physiology, nervous system, emotional landscape, early patterns, and your lived experiences.
Addressing the mind, body, and biome together is where sustainable transformation happens.
“Health begins in the gut - but healing begins in the nervous system.”
Who This Approach Is For
The Mind, Body, Biome Method is the ideal gut health programme for you if:
You’ve lived with chronic bloating, discomfort or unpredictable digestion
Your symptoms worsen with stress, overwhelm or burnout
You’ve tried diets and supplements without lasting change
Your gut feels reactive, sensitive, or “stuck”
You sense there’s more beneath your symptoms — and want a whole-body approach
You want a personalised plan and deeper understanding of your body
How It Looks In Practice
Inside the Mind Body Biome™ Method, we work across four interconnected layers of healing.
To guide you through this process, you’ll be supported by someone who works at the intersection of the gut, the nervous system, and lived experience.
Meet Your Gut Health Expert
Amanda Callenberg
I’m Amanda - a nutritional therapist and somatic practitioner in training, with a deep belief that healing the gut requires understanding the whole person, not just their symptoms.
My work combines digestive health expertise with trauma-informed emotional support, helping you make sense of the patterns your body has been carrying - and why your symptoms have persisted despite doing “all the right things.”
What matters most to me is that you feel seen, supported, and understood. I meet you exactly where you are, and together we move at a pace that feels safe for your body and your nervous system.
This isn’t about quick fixes. It’s about building a relationship with your gut, gently unwinding long-held patterns, and creating change that can finally last.

How It Works
Here’s what the journey looks like:
Step 1: Your Free Introductory Call
A 15-minute chat to understand your symptoms, your goals, and whether the Mind Body Biome™ Method is the right fit for you.
You’ll get clarity on your next steps - no pressure, just support.
Step 2: Your Initial Consultation (60 minutes)
We dive into your full health story: digestion, stress patterns, life history, emotions, habits, and physiology.
You’ll leave this session with a clear understanding of what may be driving your symptoms - and practical steps you can begin right away.
Step 3: Your Personalised Plan (Weeks 1–8 / Weeks 1–12)
You’ll receive a tailored plan integrating nutrition, lifestyle adjustments, supplement guidance (if needed), somatic tools, and nervous-system support.
This plan evolves with you - gently, safely, and at a pace your body can hold.
Step 4: Regular Support & Review Sessions
Depending on your package (12 or 16 weeks), we meet weekly or biweekly to:
review what’s shifting
adjust your plan
explore emotional or nervous-system patterns
support resilience and clarity
This ongoing support ensures you feel grounded and guided throughout the process.
Step 5: Integration & Long-Term Strategy
In the final session, we consolidate your progress, map out your long-term plan, and ensure you feel confident continuing independently.
You’ll understand your body’s signals, know what supports your gut, and feel more regulated, stable, and connected to yourself.
