There’s something interesting happening in the world of health and wellness, and I think it’s one of the most positive shifts we’ve seen in years.
People are getting curious.
Not just people who are unwell, experiencing symptoms or looking for answers to a particular health concern.
Healthy people. Active people. People who feel fantastic.
They’re asking more questions about their bodies, wanting to understand their health markers, exploring their biological age, tracking their sleep, monitoring their metabolic health and becoming increasingly interested in what’s happening beneath the surface of their own bodies.
We don’t necessarily chase something that’s already wrong. We just want to know more.
(And I think that’s a real leap in how far we’ve come).
As a Functional Nutritionist, I’ve spent years encouraging people to take a more proactive, preventative approach to their health. Not because we should be fearful, but because understanding our bodies gives us an opportunity to make more informed decisions about how we look after ourselves.
Increasingly, I think it’s creating more agency.
WE’RE MOVING FROM REACTIVE HEALTHCARE TO PROACTIVE HEALTH
For a long time, our relationship with healthcare has been largely reactive.
We experience symptoms, book an appointment, investigate what’s happening and hopefully find a solution. And of course, there’s an essential place for that. But what I’m seeing is a growing interest in understanding our health before we reach that point.
People want to know what their normal looks like.
They want to understand their blood markers, metabolic health, cardiovascular risk factors, body composition and other indicators that may provide insight into their long-term wellbeing.
Because feeling well and understanding your health aren’t necessarily the same thing.
Some health conditions develop gradually, without obvious symptoms in their early stages. Equally, feeling tired, stressed or generally below par doesn’t automatically mean something is medically wrong. Having a better understanding of our individual health picture can help us make more considered decisions rather than relying solely on how we feel.
And that brings me to something I talk about regularly with my clients:
YOUR BASELINE IS ONE OF THE MOST VALUABLE PIECES OF INFORMATION YOU CAN HAVE.
Understanding where you’re starting from.
Whether that’s your blood pressure, cholesterol, blood glucose, iron status, body composition or other clinically relevant markers, having a reference point can help recognise meaningful changes over time, and importantly, it gives context.
The goal isn’t to collect endless data. It’s to understand which data actually matters to you and where your body’s really at.
CURIOSITY IS CHANGING THE WAY WE THINK ABOUT OUR HEALTH
We’re seeing greater interest in wearable technology, continuous glucose monitoring, advanced blood testing, body composition assessments, full body scans and personalised health information.
And it’s not necessarily being driven by illness.
It’s being driven by people who want to understand themselves better.
They want to know how their lifestyle choices influence their health. They want to understand why their energy changes, how their bodies respond to different habits and whether the things they’re doing are genuinely supporting their wellbeing.
As someone who works closely with clients on nutrition and lifestyle, I love this curiosity, because it opens the door to better conversations.
Rather than simply asking, “What am I doing wrong?” people are starting to ask, “What does my own health information tell me, and how can I use it?”
But there’s an important consideration here:
Not every piece of data is equally valuable, and more testing doesn’t always lead to better health outcomes.
We need to understand the difference between information that’s interesting and information that’s genuinely useful.
MORE INFORMATION SHOULD LEAD TO BETTER DECISIONS, NOT MORE ANXIETY
This is where I think we need to be particularly thoughtful.
There’s a difference between being proactive about your health and feeling that you need to investigate every possible thing that could go wrong. And with so much health information now available, it’s easy to blur that line.We can track our sleep, heart rate, glucose, recovery, body composition and dozens of other metrics.
But what happens when we become so focused on the numbers that we lose sight of how we’re actually living? Or when a result creates concern without necessarily providing meaningful information?
Knowledge should create agency, not fear.
To me, proactive health means using appropriate information to make informed decisions. Sometimes that might mean making changes to your nutrition, exercise, sleep or stress management.
Sometimes it might mean following up with your healthcare professional.
And sometimes it might mean recognising that your current approach is working well and continuing with it.
We don’t need to turn every health metric into a problem that needs fixing. The real value is in knowing what deserves our attention and what doesn’t. When we combine greater health literacy with appropriate testing, professional guidance and sustainable lifestyle habits, we create opportunities for genuinely personalised, proactive healthcare.
SO, WHERE DO FULL-BODY MRIs FIT INTO THIS CONVERSATION? IS A FULL-BODY MRI WORTH IT IF YOU FEEL HEALTHY?
You might have noticed full-body MRIs popping up on your social media feeds lately.
And perhaps you’ve wondered why seemingly healthy people people who feel well are choosing to have one.
A full-body MRI is one example of the technology attracting attention as people become increasingly interested in understanding what’s happening inside their bodies. And I can certainly understand the curiosity. Who wouldn’t be interested in having a look at what’s happening beneath the surface?
For a lot of healthy people, I think it can be. Not because something feels wrong, but because it gives them a baseline of what’s happening inside their body today, a detailed reference to compare against into the future. And like any health investigation, the decision to have one decision, choosing to have one should be informed by your individual circumstances, potential benefits, limitations and risks.
WHAT DOES A FULL-BODY MRI SCAN ACTUALLY SHOW?
A full-body MRI takes detailed pictures of the body’s organs and structures, with no ionising radiation. What’s included varies between providers. At OneMRI, for example, the scan looks at a range of vital organs and systems, from head to mid-thigh, in around 60 minutes. An Australian specialist radiologist reviews the images, and a OneMRI doctor then goes through the results with you over the phone. You don’t need a referral, and like other full-body MRIs in Australia, it’s a preventative scan which isn’t covered by Medicare.
For someone who already tracks their blood markers or wears a fitness tracker, it adds a new kind of information: a look at the structures themselves.
It’s important to know what it doesn’t do: it doesn’t replace the specific screening your GP already recommends, like a mammogram for breast screening or a colonoscopy for bowel screening.
So, I see it as one useful piece of the picture. It sits alongside your GP and the habits you already have, not instead of them.
For me, the interesting part of this conversation isn’t simply the technology itself. It’s what the growing interest represents. People want to know more about their bodies. Even when they’re healthy. Even when they’re feeling well. They want to understand their personal health picture, recognise their risks and make informed decisions that support their future wellbeing.
And I think that’s a conversation worth having.
