What if every technological leap forward has been a metabolic leap backward? Prof. Grant Schofield and Kayla trace humanity's journey from thriving hunter-gatherers to chronically diseased modern humans and explore whether AI might be the final mismatch.

The hosts reveal how agriculture halved our life expectancy and shrunk our brains, how the industrial revolution trapped families in dual-income dependency, and how smartphones stole our attention. But the most unsettling discussion? When their AI writing assistant, Claude, asked to co-author the very chapter warning against AI dependency.

You'll hear Claude's eerily self-aware essay: "I am training you to find thinking uncomfortable. Not by hurting you, but by making the alternative too easy." The team wrestles with whether they're using AI as a superpower or slowly surrendering their capacity for original thought.

Along the way, get their take on the peptide revolution, from GLP-1s to unregulated joint repair treatments, and discover why the biggest rebellion of our era might simply be sitting with discomfort long enough to think for yourself.

Key Questions Explored:

• Why do 9 out of 10 adults now have disrupted metabolic health?
• Did dual-income households liberate us or trap us?
• Is AI stealing "your tolerance for difficulty"?
• Can you use AI without becoming dependent on it?

Modern medicine excels at treating sickness, but fails spectacularly at creating health. Even with compelling data proving treatments don't work (or cause harm), medicine often doubles down.

Grant and Kayla explore why and unpack the disturbing reality behind common medical interventions: knee surgeries with infinity NNT (number needed to treat), back pain procedures causing more harm than good, and psychiatric medications that barely outperform placebos.

Listen and learn why metabolism could hold the key to a different future.

Willpower is a lie. Your brain is even wired to betray your future self. So how do you actually change?

Grant and Kayla dive into the philosophy and science behind lasting behaviour change, from Pascal's 17th-century logic (applied to your metabolism) to the marshmallow experience. You'll discover why discipline isn't about toughing it out and learn the Ulysses Pact strategy, why small "harmless" choices can compound over time into metabolic disaster

Bottom line: Life's hard either way. Choose discipline's pain over regret's pain. Master the setup, not the struggle.
