Gut Health That Goes Beyond Food

Personal nutrition and somatic therapy for women with chronic digestive symptoms.

To help you make sense of your diet, digestion and gut imbalances, this work draws on 10 years in gut health and nutritional therapy.

Through a personalised exploration of your health, it goes well beyond a typical nutrition consultation.

And there's a reason for that.

ANOTHER PERSPECTIVE

We've been looking at gut health through one lens.

Your digestion doesn’t only respond to what’s on your plate. It responds to what your body is holding and the state of your nervous system.

Years of stress, pushing through, and ignoring your own needs or putting everyone else first all show up in how your gut behaves.

Diet, digestion, your microbiome, nutrient levels and metabolic health all play a role.

But nutritional support alone isn't enough.

So let's change the conversation.

A Familiar Place

Does This Sound Like You?

  • Your symptoms feel unpredictable. A meal that’s fine one day leaves you bloated, cramping or running to the toilet the next.
  • You’ve tried the usual routes. Low FODMAP, cutting gluten, probiotics, more fibre, less fibre. Some may have helped for a while. Others made little difference.
  • Your safe food list keeps getting shorter. Less to eat, more to worry about, and still looking for the next thing to cut out.
  • Your tests say “normal”.  But there's been little exploration of your stress, sleep, hormones or what the last few years have really been like.
  • Your gut often flares when life gets stressful.  Before a big meeting, after a difficult conversation, or during periods when everyone seems to need something from you.
  • You plan your life around your gut.  Where the toilets are, what's on the menu, whether to say yes at all.

Somewhere along the way, it became harder to trust your body.

Meet Amanda

"I help your body feel safe enough to heal, then we give it the nourishment it needs"

Amanda Callenberg holding a mug in a calm, light kitchen

Hi, I’m Amanda. I'm an Australian, London-based nutritional therapist and somatic counsellor.

My journey into nutrition came after many years of struggling with my own digestive issues and emotional overwhelm. I wanted to understand what was happening in my body.

This led me to study Nutritional Therapy at the renowned College of Naturopathic Medicine (CNM), followed later by further training in somatic counselling and the mind-body connection.

What I’ve learned is that gut symptoms often build up over years through nutrient depletion, gut imbalances, dysregulation and disconnection from self.

Mind. Body. Biome. brings together personalised nutrition, functional testing and Dr Gabor Maté’s Compassionate Inquiry approach to explore both what’s happening in your gut and the deeper patterns behind your symptoms.

Dr Gabor Maté’s work gave me a language for something I’d been seeing in practice for years. 

Women living in bodies that had become reactive and overwhelmed after a lifetime of pushing through and overriding their own signals.

I've since completed more than 400 hours of training in his Compassionate Inquiry approach, which explores how our experiences shape the way our nervous system responds today, and how this can affect digestion, hormones and immunity.

Nutrition is still important. Testing has its place. Protocols can be incredibly useful. But most important is addressing what’s keeping your body reactive, and recognising the experiences that shaped those responses in the first place.

The Process

The Deeper Work

"A body that doesn't feel safe cannot heal."

Understanding your symptoms is one thing. Understanding why your body has developed these patterns, and what it needs to change them, is where the deeper work begins.

By looking beyond your symptoms and helping your entire body feel more settled, we create the right conditions for targeted nutrition protocols to have a real, lasting impact. Regular calls and ongoing support mean we can move at the pace your body needs.

  1. Safety

    We start with your story: what's happening in your life now, what was happening before symptoms began, your health history and how your symptoms behave. We focus on calming your nervous system while establishing the foundations: blood sugar balance, sleep, hydration, regular bowels and proper nourishment.

  2. Explore

    Then we investigate what's driving your symptoms, through testing where useful, exploring digestion, your microbiome and nutrient status. Alongside this, through gentle psychotherapeutic conversation, we look at the experiences and patterns that may have shaped how your nervous system responds today.

  3. Rebuild

    We use targeted, personalised nutrition protocols alongside somatic work to change the patterns keeping your body reactive. As you begin to connect the dots and understand yourself more deeply, we gradually reintroduce foods and experiences you've been avoiding, rebuilding confidence and trust in your body.

Throughout: Weekly 1:1 sessions to begin with, then fortnightly, with support in between.

Google review from Ruth describing improvements in IBS symptoms through personalised nutrition and somatic work with Amanda Callenberg.

I saw a complete reduction of my IBS symptoms and went from feeling confused by my body to having so much clarity and peace. Doing somatic experiencing alongside the nutritional work was invaluable. I felt held, seen and known by Amanda at every stage of the journey.

Review from Abi N, part 1, about working with Amanda Callenberg.

I was telling my partner recently how grateful I was for the work I'd done with Amanda. He said, "I think working with Amanda has changed your life." I agreed, explaining how much less I worry about my gut and how I no longer panic about going out to eat. But he said, "No, no, it's more than that. You now see joy in life. You're joyful, you look forward to things, and it's changed our relationship."

Review from Abi N, part 2, about feeling safe and supported with Amanda Callenberg.

Amanda has made me feel so safe. She never judges me, even when I feel like I'm coming with a new problem every time. She always listens and helps me explore what I'm feeling, what might be happening in my body and what I need to feel safe. Over time, she's helped me understand that it's all connected, and that we're okay. I can't express the enormity of the difference this has made to how I feel in myself and to my life.

Review from Jayne M about functional testing and an evidence-based approach with Amanda Callenberg.

I very much enjoyed working with Amanda. The most revealing thing was the functional testing, which showed I had four types of streptococcus in my large intestine. After that, we were able to take a more targeted approach without using antibiotics. For anyone who likes an evidence-based approach, like myself, this is essential and allows you to really measure progress. Thank you Amanda.

Review from Amy T about digestion, emotional patterns and working with Amanda Callenberg.

I came for help with my digestion and ended up learning quite a lot about myself. Particularly how much I tend to put other people's needs before mine. I hadn't really considered that the way I deal with things emotionally were relevant to my health. It's been eye-opening. Amanda has a way of asking questions that stay with you long after the session.

Review from Louise M about her experience of IBS support with Amanda Callenberg.

I'd been dealing with IBS for probably 12 years and thought I'd just have to live with it. I tried Low FODMAP, probiotics, and supplements and a dietitian, Amanda was the first person who looked at everything else going on in my life, which at the time was quite a lot! Fast forward six months and finally going away with friends and not constantly worrying. I even had a curry last weekend. Never thought I'd be saying that.

Review from Jessica W about understanding her body and health anxiety with Amanda Callenberg.

For me the biggest change hasn't actually been the symptoms themselves, although they are definitely better. Amanda helped me slow that whole process down and understand what was happening in my body. I won't pretend I never get anxious about my health anymore because I do. But it doesn't consume me in the same way and I feel like I have a much better understanding of myself now and I didn’t expect that from seeing a nutritionist.

Review from Tessa S about wellbeing and recognising personal patterns with Amanda Callenberg.

I've spent so long feeling tired, uncomfortable and just generally not myself that I hadn't noticed how much had changed. Now I'm sleeping properly, eating normally again and actually looking forward to making plans. But I think the biggest thing is that I've stopped pushing myself quite so hard. Amanda helped me see things I hadn't even realised I was doing. I'm so grateful.

An Honest Invitation

Is This the Right Fit?

This isn't a programme you follow. It's a process we work through together. What we do evolves as we learn more about you and how your body responds.

This is for you if

  • You've tried many of the conventional approaches, but your body still doesn't feel at ease.
  • You want nutrition support and testing, but recognise that food alone isn't the whole answer.
  • You're open to exploring how your experiences, emotions and nervous system influence your symptoms.
  • You're ready to invest time and energy in a personalised, collaborative process.

This isn't for you if

  • You prefer experimenting independently, rather than working closely with a practitioner.
  • You're primarily looking for a test, supplement recommendation or one-off consultation.
  • You'd prefer a ready-made plan with minimal ongoing involvement or occasional check-ins.
  • You need something low-cost and lower-touch or you're not in a position to make this a priority right now.

COMMON QUESTIONS

Frequently Asked Questions

I've tried everything before, how is this different?

Most people come to me after trying restrictive diets, supplements or generic approaches.

These can be helpful in providing relief for a period, but they rarely address the whole picture or the underlying drivers of ongoing gut issues.

Rather than giving you another protocol to follow, this work explores what's beneath your symptoms to understand how your nervous system and the patterns you've developed over time are keeping your gut in a cycle of reactivity and dysfunction. As our understanding of the gut–brain connection grows, it becomes increasingly difficult to justify treating nutritional and physiological support as separate from deeper emotional and psychological work.

This is really common. Standard tests are important for ruling out significant conditions. However, they don't typically assess microbiome diversity, how well you're digesting and absorbing your food, markers of inflammation, or the wider functioning of your digestive system.

Advanced functional tests, such as GI360, offer a different perspective on how your digestive system is working, so any support we use, including a protocol, can be more targeted.

No. Those things can be useful, and tools for moment-to-moment regulation are helpful, but they're only a small part of the picture.

Simply trying to calm your body down is a way of managing stress. My work is about understanding the patterns that shape how your nervous system responds, including what's happening in your life now and what may have been established much earlier.

We work with these patterns, alongside your gut health and nutrition, to create longer-term shifts in how your body feels and functions.

No. Although Compassionate Inquiry is a psychotherapeutic approach, it simply shapes how I listen and the questions I ask. This isn't about digging into your past.

My training as a trauma-informed somatic counsellor means I'm better able to support what comes up as we work together, both psychologically and through what you experience in the body.

Some of these words may sound intimidating, but the work itself is about understanding what's present for you now, how you relate to it and how that may connect to earlier experiences.

Tests and supplements are additional costs. Testing is recommended when it helps us better understand your symptoms and guide our next steps. Supplements can be useful, but they're not the starting point.

The foundation of your programme is depth, structure and support: understanding your symptoms and their contributing factors, developing a personalised plan that evolves with you, and regular, in-depth 1:1 sessions.

The goal is clarity and calm: a better understanding of your body and confidence in the process.
