Prevention is Cure

Prof. Grant Schofield explains ketosis from first principles: what it is, why it matters, and how it differs from simply "eating low carb." We talk about insulin resistance and metabolic syndrome, which affect a significant share of adults today, the surprising wartime origins of chemotherapy.
Prevention is Cure is sponsored by Prekure - a New Zealand education organisation with a bold vision: to redefine the future of medicine. Prekure's CEO, Louise Schofield, saw that people weren't getting the support they deserved, and decided to do something about it. Her answer? Train masterful health coaches who can empower people with the knowledge and tools to prevent illness - not just treat it.

In this episode, Grant Schofield sits down with ocean swimmer and activist Jono Ridler, fresh off an extraordinary feat: swimming just shy of 1,400km from North Cape to Wellington in just 90 days.
Jono shares what drove him to take on the swim, the physical and mental toll of months in open water, and the deeper mission behind it: raising awareness of what's happening beneath the surface of our oceans, including the impact of bottom trawling on fragile deep sea ecosystems. He talks candidly about training while working full time and raising a young daughter, navigating shark encounters, adapting to dropping water temperatures, and the injuries and setbacks along the way.

A Herald story revealed New Zealand households spend $20 million a year on energy drinks, and some people are drinking two litres a day just to get through a shift. In this episode Prof. Grant Schofield and guest co-host, Sam Schofield unpack the predatory marketing with energy drinks aimed squarely at young boys, why a single 500ml can hides 13 teaspoons of sugar and 160mg of caffeine, and the B6 toxicity risk almost nobody talks about, with recorded cases here in NZ and Australia.
From there:
- Are "sugar-free" lollies just a clever scam? Should governments regulate the food environment the way they regulate everything else?
- A surprising new zinc trial where people lost nearly 3× more weight on the same calories.
- The real story on seed oils and your cell membranes, which is more nuanced than the internet tells you.
- And why the coming robot age might make some of us healthier, not sicker.
This is general discussion, not medical advice. Talk to your own clinician before changing anything.

In this episode of Prevention Is Cure, Prof Grant Schofield and Sam Schofield dive deep into the most explosive topic in metabolic health right now - have we actually cracked weight loss and aging? From the latest GLP-1 triple agonists showing 30% body weight loss, to gene therapies that can reverse the age of individual cells, the science is moving faster than most people realise.But here's the uncomfortable truth: 9 out of 10 people regain the weight when they stop. The "Ozempic personality" is real. And the first human trial of Yamanaka factor therapy just began.
We cover:
→ The 4 weight loss options (and which actually works long-term)
→ The newest GLP-1 drugs you've never heard of — and can't pronounce
→ What "food noise" is and why killing it might cost you more than hunger
→ Longevity escape velocity — the first person to live to 1,000 may already be born
→ Yamanaka factors and the science of reversing cellular age
→ Why Grant believes prescribing these drugs without behaviour change is unethical
