This week we're throwing it back to the 2025 Thrive360 Health Conference, where Rudy and Shaun presented one of our favourite talks: Know Your Numbers.

In a world filled with endless health tests and conflicting advice, how do you know which numbers really matter? In this live presentation, we explore some of the most important biomarkers and health metrics that can help predict future disease, assess your current health, and guide better lifestyle decisions. From cardiovascular risk and metabolic health to fitness and healthy ageing, we discuss the numbers that deserve your attention.

This episode was recorded live, so if you're able to, we highly recommend watching it on YouTube rather than just listening, as many of the concepts are explained using slides and graphs.

The best time to know your numbers was yesterday. The next best time is today.

In this episode of the InnerSight Podcast, Rudy and Shaun take a balanced, evidence-based look at one of the most talked-about topics in modern health and longevity: peptides.
Some peptides are transforming medicine and changing the way we treat obesity, diabetes, and metabolic disease. Others have generated enormous excitement despite having very limited human data. So how do we separate genuine medical breakthroughs from premature hype?
The discussion begins with the basics—what peptides are, how they work, and why they have become so popular in health, fitness, recovery, and longevity circles. Rudy and Shaun also explore the hidden risks associated with unregulated and black-market peptides, including concerns around quality control, contamination, dosing accuracy, and safety.
The episode then breaks peptides into key categories, including:
Weight loss and metabolic health
Recovery and injury healing
Muscle growth and performance
Energy and mitochondrial function
The hosts discuss the remarkable success of GLP-1 medications, the growing popularity of recovery peptides such as BPC-157 and TB-500, and why enthusiasm for some compounds currently exceeds the available scientific evidence. They also explore emerging peptides and mitochondrial therapies, including MOTS-c, that may become important areas to watch in the coming years.
Throughout the conversation, Rudy and Shaun maintain a neutral perspective: some peptides are supported by strong clinical evidence and are already reshaping healthcare, while many others remain promising but largely unproven. If you're curious about peptides and want to understand the science, the risks, and the opportunities without the marketing spin, this episode is for you.

What does it actually take to fuel hard training without burning out your body for the long run?

In this episode of InnerSight, we sit down with sports dietitian and endurance athlete Helanie van Rooyen to unpack the real science behind performance nutrition — and where so many athletes go wrong.

We explore Relative Energy Deficiency in Sport (RED-S) and why under-fueling is more common (and more dangerous) than most people realise. Helanie breaks down the key nutrients every endurance athlete should be paying attention to — creatine, protein, magnesium, and vitamin D — and explains not just what to take, but why, when, and how to know if you're actually deficient.

Whether you're a competitive athlete, a weekend warrior, or someone trying to build sustainable habits that support both performance and longevity, this conversation will shift the way you think about food as fuel.

In this episode:

What RED-S is and the warning signs you might be missing

How to get your protein right for endurance (it's probably not what you think)

Creatine — is it just for gym bros, or should endurance athletes be using it?

Why magnesium and vitamin D are chronically overlooked in athletes

How to fuel performance without sacrificing your long-term health

Muscle is one of the strongest predictors of how well — and how long — we live. But most people don’t know how to train it properly, especially as they get older.In this episode, we have Hannes Swanepoel as our guest and we take a practical, biokineticist-driven approach to muscle and longevity. We focus on how to assess where you are, what actually needs to improve, and how training should evolve across different ages and abilities.From strength vs function to power, balance, and injury prevention — this is a grounded, real-world guide to building a body that lasts.

In this episode of the InnerSight Podcast, Rudy and Shaun sit down with chiropractor and author Cuan Coetzee to explore the powerful idea that movement is medicine.

Cuan shares the personal and professional journey that led him to write his book Movement Is Medicine, including the experiences in clinical practice that shaped his thinking about pain, posture, mobility, and modern sedentary lifestyles.

From there, the conversation expands into one of InnerSight’s core pillars of longevity: movement. Together, they unpack why how we move may be just as important as how much we move, how poor movement patterns develop over time, and what people can do to restore healthier movement as they age.

The discussion bridges clinical insight with practical advice, touching on topics such as mobility, injury prevention, daily movement habits, and why movement quality is essential for maintaining musculoskeletal health and long-term wellbeing.

If you're interested in living longer, moving better, and understanding your body, this episode offers a thoughtful look at how movement can be one of the most powerful tools for lifelong health.

New year motivation is high—but most health resolutions fail because they’re vague, generic, and disconnected from meaningful data.

In this episode, Rudy and Shaun unpack why goals like “lose weight” or “get fit” rarely work without a clear plan and measurable markers.

They explain why knowing your key health numbers—from metabolic and cardiovascular markers to body composition and fitness metrics—is essential for long-term health and longevity. The conversation shifts health from guesswork to strategy.

The episode also introduces the InnerSight health app, designed to help clients track their data, understand what matters most, and build a personalised roadmap rather than following one-size-fits-all advice.

If you’re starting a new year and want clarity instead of confusion, this episode will help you focus on the numbers that truly move the needle.

In this milestone 30th episode of InnerSight, we welcome dual-qualified physician & functional medicine expert Dr Roos. We explore why healthy bones are much more than structural support — they’re central to mobility, resilience, and longevity. We dig into the science of Osteoporosis: what happens when bone density and architecture deteriorate, how risk increases with age, hormonal changes and lifestyle, and why fractures can dramatically impact quality of life.

But rather than waiting for a fracture to strike, Dr Roos advocates a proactive, “buy-your-future-mobility” approach. Drawing from a functional medicine framework, we discuss how optimized nutrition (calcium, vitamin D, vitamin K, magnesium, protein), inflammation management, gut health, balanced hormones and tailored exercise — especially weight-bearing and resistance training — work together to maintain bone strength over time.

We contrast standard guidelines (focused on bone mineral density, scanning, and pharmacological treatment) with a longevity-oriented mindset: building “functional bone quality,” reducing fracture risk, and supporting whole-body health. With Dr Roos’s dual expertise, we unpack what bone health really means — not just surviving, but thriving into older age.

Tune in to discover concrete strategies for safeguarding your skeletal future and unlocking your maximum potential for lifelong strength.
