The newsletter and blog are where I unpack what I’m reading, noticing and rethinking, from health and human behaviour to prevention, performance and the science that sits underneath it.
Society often promotes body size as the only defining metric of health, but what if I told you it's actually the wrong metric for most of us. The real question: is your body strong enough to carry you into old age with your independence intact?
As New Zealand hunkers down for winter, one supplement may be worth another look, especially for those who spend most days indoors. This is the one supplement I've actually come round to.
The sauna is an ancient ritual that's made a modern comeback with the wellness movement. But unlike some 'health hacks', there is solid science to back sauna up. Let's talk about it.
Nutrition scams are everywhere. This isn't one. But it's no magic wand either. Here's what the evidence actually shows about time-restricted eating, and how shrinking your eating window unlocks natural fat burning.
I've spent most of my career arguing that we mostly don't benefit from supplements. This is the exception. Over 680 clinical trials have looked at creatine in humans, here's what they actually show for muscles, brain, and mental health.
I Walked Away From My Professorship. Here’s Why. A year ago, I was fifteen kilometres into an off-road half marathon in Rotorua when a medical support runner came sprinting up the trail toward me. He looked at me with genuine concern. “Don’t stress, I’m here. Is it a broken ankle?” From the way I was moving, gingerly clambering down a
Choose your hard (Part 3): Staying Human in the Age of AI We are living through a massive, uncontrolled experiment in human biology. We have taken a nervous system evolved for scarcity, movement, and silence, and dropped it into an environment of personalised algorithms which keep us scrolling and stop us thinking. By thinking, I mean being able to reflect
When was the moment you realise AI is better than you at your own job? Maybe you watched AI write a block of code faster than you can think. Maybe you saw a strategy drafted in seconds that would have taken you a week to sweat over. Maybe you saw 6 months of accurate literature reviews, writing and synthesis done
Choose Your Hard (Part 2): The Practical Guide to Getting Shit Done (on the tail of my previous article “Choose Your Hard: A Philosophical Guide to Getting Shit Done”) Being healthy is hard. Being unhealthy is hard. Discipline is hard. Regret is hard. You can pay with discipline now, or you can pay later with regret, chronic disease, and the
Being healthy is hard. Being unhealthy is hard. Discipline is hard. Regret is hard. Most people fail at health changes not because they lack commitment, but because they lean on willpower alone. Biology doesn’t back that approach. Willpower is overrated; it collapses under stress. The real skill is setting up your environment and systems to bypass willpower entirely. That’s the secret sauce
Is Failing to Prescribe Lifestyle Medicine Malpractice? Modern medicine is extraordinary. We can administer all sorts of drugs and procedures. We can reattach a severed finger. We can open up your skull and remove a brain tumor. We can scan and detect complex pathologies deep inside the body. And so much more. Yet every day, we make a quiet ethical
We have entered a new era of obesity medicine. The short-term results of GLP-1 agonists (like Ozempic/Wegovy) are undeniable. But we are ignoring a massive, looming question: What happens when you stop? The data is clear: Without an exit strategy, we are setting patients up for a “rebound” that leaves them metabolically and functionally worse off than when they started.
