What is VO2 Max & Could It Be The Most Important Health Metric?
Episode 33
Sunday, August 23, 2026 • Duration 23:12
How do you improve VO2 max? In this episode, you'll find out why this single fitness number has become one of the most powerful predictors of how long and how healthily you'll live — with research suggesting low VO2 max carries greater health risks than smoking, diabetes, or even heart disease. You'll learn what a good VO2 max looks like for your age, how to measure it through a lab test, the Cooper test, or your fitness watch, and how to improve it through zone 2 training and high-intensity interval training. I've put together free VO2 max training programmes to get you started — grab them using the link in the show notes.

Could aging truly be optional? Dr. Hany Demian brings a fresh perspective on the future of healthcare through the lens of longevity medicine, regenerative medicine, biological age, and preventative health. Rather than focusing only on treating disease after it appears, he shares how root-cause medicine, cellular health, and better daily habits may help us slow down the aging process and improve long-term health and wellbeing.
We unpack how biological age differs from chronological age, why sleep, nutrition, exercise, and stress management are such powerful drivers of health, and how small lifestyle changes can make a big difference over time. Dr. Demian also explains the role of emerging approaches like peptides, exosomes, stem cells, hormone optimization, and other regenerative therapies in supporting healing and recovery.
If you're interested in healthy aging, reverse aging, functional medicine, health optimization, and the science behind living longer and better, this episode is for you. You'll hear practical insights you can apply now, alongside a bigger vision for what the future of medicine could look like when healthcare becomes more proactive, personalized, and focused on prevention.
Guest credentials:
Dr. Hany Demian is a longevity and regenerative medicine specialist with clinical experience across Canada, Egypt, and the US. His work focuses on helping patients understand their biology, improve health outcomes, and take a more proactive approach to aging well.

Is Your Coffee Toxic? - The Truth About Mycotoxins & Coffee

Is Your Coffee Making You Sick? - The Truth About Mycotoxins in Coffee
You've probably seen the hype — "mouldy coffee," "toxic beans," "your morning cup is slowly poisoning you." But is there any truth to it, or is it just clever marketing designed to sell you expensive "clean" coffee?
In this episode, we cut through the noise and take an evidence-based look at mycotoxins in coffee. We cover what mycotoxins actually are, why ochratoxin A (OTA) and aflatoxins keep coming up, and what independent studies really show about contamination levels in green, roasted, and instant coffee.
We also look at what happens during roasting and brewing — and why the mould found on raw coffee beans tells a very different story to what ends up in your cup. Plus, how EU food safety regulations and maximum limits for ochratoxin A apply to the coffee you buy every day, and whether low-mycotoxin or mould-free coffee is worth the premium.
If you're a health-conscious coffee drinker wondering whether to switch brands, ditch instant, or invest in specialty coffee, this episode gives you the practical, no-hype breakdown you need.
You'll learn the following about mycotoxins and coffee
What mycotoxins are and how they form on coffee beans
Whether roasting destroys mycotoxins
How your total dietary mycotoxin load matters more than coffee alone
