Hi, I'm Kelly
Meet your Coach - Kelly O'Donnell
I spent years pushing hard — corporate career, high performance, bodybuilding, and raising two girls alone. But after my last competition, my body broke down. I gained weight I couldn’t shift, battled brain fog, gut issues, hormone chaos, and extreme fatigue. Doctors told me I was fine, but I knew I wasn’t.
That rock-bottom moment led me to functional health. I discovered layers of imbalance and dis-ease that were never picked up by conventional medicine — but could be reversed.
I combined this deep healing journey with my background in nutrition and fitness to create a whole-body, root-cause approach. Now I help women overcome the symptoms they’ve been told to live with — and rebuild health from the inside out, physically, emotionally, and mentally.

Success Stories
Duncan MacPherson
"I reached out to Kelly at a point where I was feeling pretty low, both in terms of mindset, health and how I felt in my body. I’d previously been in shape but let things slip, with work taking over and excuses creeping in.
We’ve focused on mindset, gut health, and nutrition and exercise, that fits around my life and I’ve dropped over 10kg.
Kelly’s approach is fun, supportive, and totally non-judgemental. She keeps you accountable but works with your life, not against it. It’s not always easy, but she’s there when you need a boost, and the results speak for themselves.
If you're looking to prioritise your health and get back on track in a way that actually feels good, I can't recommend her enough."
Hannah Graham
"Several weeks into Kelly’s programme and the shift in my health has been incredible. I was struggling with severe digestive issues that were really debilitating, constant discomfort, low energy, and brain fog that made it hard to focus. I felt sluggish, uncomfortable in my clothes, and just not myself.
Since starting, my mood has lifted, my sleep and mental clarity have improved massively, and my stress levels are so much more manageable. And while weight loss wasn’t my main goal, I’ve already lost several pounds.
This has truly been one of the best investments I’ve ever made for my health and wellbeing."
Anne Alexis Ogazi
"I was slow, sluggish and low in energy, that was me for so many years. My digestion and gut health were impacting my daily life and the dreaded 'bloat' was really uncomfortable.
Kelly listened to my needs & tackled these issues head on! Her nutritional knowledge & accessible approach, took the mystery out of how.
Within the first month, my digestion, energy & sleep were massively improved and 6 months later this doable programme fits seamlessly in to my daily routine.
Bonus.....weight loss too, but this feel good living, right now, is priceless! I'm sticking with this.
Thanks Kelly"
