Feel Like Yourself Again.
Understand your body. Rebuild your health. Create more freedom.
If you're tired of feeling tired, foggy, stressed or simply not quite like yourself,
let's stop guessing what your body needs — and start understanding it.

You’re doing a lot of the right things.
You eat pretty well. You exercise. You care about your health.
And yet...
Your energy isn't what it used to be.
Your sleep could be better. Your digestion has become unpredictable. Your brain feels foggy. Your hormones or stress levels seem to affect you more than they should.
Maybe your blood tests are even “normal”.
But you know you don't feel your best.
The question is: why?
Your Symptoms Aren’t Random.
Your body is a system.
Your energy, digestion, hormones, metabolism, nutrient status, sleep and nervous system constantly influence each other.
So rather than looking at each symptom in isolation, I help you connect the dots.
We look at your health history, symptoms, lifestyle and existing results and use blood testing or functional lab testing where appropriate.
Not to collect more data.
To understand what your body is trying to tell us.
This Isn’t Conventional Health Coaching.
I'm not here to give you another generic meal plan, recommend a cupboard full of supplements or make you dependent on seeing a practitioner forever.
We build systems.
Understand what's happening.
Identify what matters most.
Create the right conditions.
Observe how your body responds.
Adjust.
Learn.
The goal isn't for me to become the expert on your body.
It's for you to become one.
Hi, I’m Larissa.
I'm an Integrative Health Practitioner & Student Nutritional Therapist with a background in epigenetics, holistic counselling, meditation and nervous system work.
But more than anything, I'm fascinated by one question:
Why does the body respond the way it does?
Because once we understand that, health becomes much less about following rules — and much more about understanding ourselves.
My role isn't to tell you how to live.
It's to help you connect the dots, understand your physiology and build the foundations that allow your body to function better.
Until eventually, you need me less.
Back to You
Your health. Back in your hands.
A personalised 12-week health program designed to help you understand why you don't feel like yourself — and what to do about it.
Together, we:
Understand → Investigate → Rebuild → Learn → Become independent
Using nutrition, lifestyle, nervous system support, targeted supplementation and testing where appropriate, we create a strategy around your body and your life.
So you don't just feel better.
You understand how to stay better.

"Larissa has a warm, open presence and is highly knowledgeable across many aspects of health and wellbeing. She came well-prepared, making the most of our session by providing a thorough, science-backed plan. She addressed my concerns from all angles - emotions, environment, diet, and practical steps for healing. The approach was comprehensive yet manageable, with clear strategies to move forward. If you're ready to improve your health, I highly recommend her."

„ I’ve always been my own doctor — trusting my body, walking the holistic path, and rarely seeking outside advice. But speaking with Larissa was a breath of fresh air. She met me exactly where I was and matched the high standard I hold. The health plan she created felt completely tailored — and I’m still working with it months later. Larissa knows the body deeply. She works with it, not against it. If you’re serious about your health, talk to Larissa. She gets it."

„I highly recommend Larissa Behrend-Sims!! I saw her today and her knowledge and care was so refreshing and she has been so helpful even after the appointment with links, PDFs and care plans to work towards. There’s been no forceful intentions on buying things personally from her or anyone she could “endorse”, it’s all just recommendations and at your own pace to buy them from reputable sites (which all have high reviews) or trying simple things we may already have at home. I was skeptical about trying yet ANOTHER new specialist but I’m feeling really optimistic after leaving this session with her. So yeah, highly reccomend if you’re umming and ahhhing to just make the appointment!!"

As Seen on TEDx
Our health is shaped by a complex interaction between genetics, environment, lifestyle and experience.
My work in epigenetics was also the subject of my TEDx talk, exploring how the lives we live can influence our biology.
Health Isn’t The Final Destination.
We spend a lot of time talking about health as if being healthy is the ultimate goal.
But is it?
Because the real value of having energy isn't simply having more energy.
It's what you can do with it.
When you sleep well, think clearly and feel resilient, you have more capacity.
For your relationships.
Your work.
Your family.
Your ideas.
And for changing the parts of your life that no longer feel right.
Health gives you freedom.
Freedom to participate.
Freedom to choose.
Freedom to create a life rather than simply having enough energy to get through it.
Health isn't the destination. It's the foundation for everything that comes next.
You Don’t Need Another Health Hack.
You need to understand your body.
What supports it.
What drains it.
What it's responding to.
And what helps it come back into balance.
Because your body has been giving you information all along.
Maybe it's time to learn how to read it.
