Alicia McCarthy a nutritionist, health and wellness coach based in Christchurch, New Zealand, specialising in autoimmune disease, gut health and reducing symptoms of chronic health challenges with a holisitic dietary and lifestyle approach.

Personalised nutrition and wellness coaching to improve gut health, reduce chronic inflammation, and naturally manage autoimmune symptoms.

Gone are the days of accepting life as is.

The Grounded Health mission is simple: to help you feel better in your body every day.

Hey, I’m Alicia - founder of Grounded Health, a qualified nutritionist, and wellness coach. I know what it’s like to struggle with health, because I’ve been through it myself.

I offer online 1:1 nutrition consultations and health and wellness coaching programs, providing holistic, evidence-based support that looks at the bigger picture of everything influencing your wellbeing. Through personalised health coaching, we’ll create strategies to help you improve your health, manage symptoms, and achieve your goals with confidence.

From dealing with autoimmune disease since a young age, I understand the challenges involved in finding answers and the feelings of desperation when things just don’t seem to be working.

I know how hard it can be to change habits and behaviours and understand the mental challenges involved, especially when dealing with chronic illness, gut issues, fatigue, inflammation, and other symptoms, that can make everyday tasks and activities really challenging.

At the heart of my practice is a commitment to providing evidence-based health support that empowers you to make informed choices. You’ll get guidance and accountability to save you time, avoid unnecessary trial and error, and feel supported while building sustainable habits for long-term wellbeing.

I provide ongoing support so you don’t have to go through the process alone - helping you move toward a healthier, more balanced lifestyle at a pace that works for you.

Based in Christchurch, New Zealand, I work with clients online across New Zealand and worldwide.

Areas of expertise

Whether you’re living with a chronic illness, navigating an autoimmune disease, managing gut health issues, or trying to build healthier habits, I provide personalised, evidence-informed nutrition and wellness support.

I specialise in helping women with:

Nutrition for Autoimmune disease – including rheumatoid arthritis, coeliac disease, psoriasis, Hashimoto’s thyroiditis, and inflammatory bowel disease (IBD)
Chronic fatigue and low energy – support for brain fog, poor sleep, and chronic inflammation
Digestive health and gut symptoms – including irritable bowel syndrome (IBS), constipation, diarrhoea, bloating, discomfort after meals, and leaky gut (increased intestinal permeability)
Building sustainable lifestyle habits – creating routines that support long-term wellbeing, resilience, and symptom management

Your symptoms are not random - they’re messages from your body.

Together, we’ll uncover what those signals mean and identify the root causes behind them. My role as a nutritionist and wellness coach is to guide you in reducing discomfort, restoring balance, and improving your quality of life through holistic nutrition and lifestyle strategies.

With the right tools, you’ll feel more connected to your body - and more empowered to support your long-term health and wellbeing.

Testimonials

“I found working with you was delightful, I felt at ease and that you were very knowledgeable about gut health and particularly IBS. You also offered on-going support if needed and had suggestions and recommendations for me for going forward. It changed my life, I felt normal again. definitely recommend.”

My experience of working with Grounded Health, to improve my gut health, has been fantastic.
Before I started working with Grounded Health, I had put up with poor gut health for 2 years. I had thought that because I turned 30, that this was just the way things would be.
It was affecting both my social and work life.
Since working with Grounded Health, things have dramatically improved and I haven't felt this good in years. I really enjoyed working with Alicia, and I found her coaching style was the right fit for me. She has great practical knowledge and a wealth of theoretical knowledge on gut health. I liked the way she would review the data and bring it together in an easy to understand way. I also liked how she would start by focusing on the basics of food nutrition, as my knowledge in nutrition wasn’t as good as I had thought. One thing that surprised me was that many of the foods I thought were very good for gut health actually weren’t as good as I had thought and with a few changes suggested by Alicia, my gut health improved dramatically.
I, like most people I feel, didn’t exactly know how to get my gut health back on track and thanks to Alicia, I feel like myself again.
To anyone who is struggling with gut issues, I would say to get in touch with Grounded Health and start your journey to improving your quality of life!
