This conversation breaks open a big shift happening in health and fitness: moving away from generic programming and into precision health.
Mish sits down with Dr Cam McDonald to unpack why “one-size-fits-all” has always been flawed—and what actually sits underneath individual differences in body composition, behaviour, performance, and health outcomes.
The core idea is simple, but uncomfortable for the industry: people don’t respond the same way because they’re not built the same way. Genetics, early development, environment, and hormonal profiles all shape how someone trains, eats, recovers, and even thinks.
This episode pulls that apart and then connects it to what’s coming next—AI tools that can actually measure and apply those differences in real time.
What You’ll Learn
Why individuality isn’t just a buzzword
Dr Cam explains how differences start at conception and are shaped further in early life. From there, biology influences everything—hormones, behaviour, preferences, and responses to stress, food, and exercise.
The 6 Precision Health Types (and why they matter)
A simplified framework used to group patterns in physiology and behaviour:
Activator – high adrenaline, thrives on intensity, needs frequent fuel Diplomat – calm, structured, avoids stress spikes, prefers steady movement Crusader – goal-driven, endurance-focused, aligns with traditional “healthy” guidelines Guardian – community-focused, stress-responsive weight gain, strong and resilient Connector – thrives on social interaction, physiology improves with connection Sensor – highly sensitive nervous system, needs calm environments and gentle inputsThe point isn’t labels—it’s recognising patterns. Different bodies need different strategies.
Why “the research says…” isn’t enough
Most studies show averages. Individuals within those studies often respond wildly differently.
This is where trainers get stuck:
One client thrives Another plateaus Another regressesSame plan. Different outcomes.
That’s not a compliance issue. It’s a mismatch.
Where the fitness industry is getting it wrong
Programming is still built around:
Generic guidelines Standardised meal plans Uniform training approachesThe problem: those models often favour one physiology (typically Crusader-type profiles), while others are left thinking they’re the issue.
How AI changes the game (if used properly)
This isn’t about ChatGPT writing programs.
It’s about clinical intelligence tools that:
Analyse individual biology Map symptoms and patterns Predict responses to training, food, and stressUsed properly, it doesn’t replace coaches—it makes them more precise.
The Webinar Series (What You’ll Get)
Dr Cam is running a 4-part free series diving deeper into this work:
AI in Health & Fitness
What actually works vs what doesn’t (and why general AI tools fall short) Women’s Health
Moving beyond dismissed symptoms into personalised strategies Chronic Disease & Neurodivergence
Getting to root causes instead of managing symptoms Longevity & Performance
Why biohacking isn’t one-size-fits-allEach session builds on the same idea: better data → better decisions → better outcomes.
