In this episode, Sarah Court and Laurel Beversdorf begin a two-part investigation into Louisa Nicola and the rapidly growing industry built around Alzheimer's prevention, brain optimization, and women's brain health. They examine how legitimate scientific concerns about dementia become transformed into highly marketable narratives, and explain the difference between what current evidence supports and what many online health personalities confidently claim.

Sarah and Laurel break down the strongest evidence on dementia prevention, including findings from the 2024 Lancet Commission, and discuss what is known about exercise, vascular health, hearing, vision, education, social connection, and other modifiable risk factors. They also introduce concepts they call mechanism theater, evidence cosplay, and the fear-to-action marketing pipeline, showing how preliminary research is often stretched into certainty to sell protocols, supplements, and personal brands. Along the way, they critically examine several of Nicola's most common claims—including that Alzheimer's starts in your 30s, that women face six times the risk, and that heavy resistance training is uniquely protective—and compare those claims with the available evidence.

Part 2 of this series will continue the investigation into Louisa Nicola's recommendations, products, and marketing strategies.

In this episode, Sarah Court and Laurel Beversdorf continue their conversation with Dr. Stu Phillips, one of the world's leading protein researchers. They dig into the latest ACSM Position Stand on Resistance Training, unpacking what it actually says about strength, hypertrophy, power, progressive overload, and why many of the debates happening online are driven more by certainty than by evidence.

They also explore why protein has "jumped the shark," how marketing has outpaced the science, whether menopausal women really need dramatically more protein, and why consistency—not optimization—is still the most powerful exercise strategy. Throughout the conversation, Stu explains why scientific nuance often gets lost on social media and why changing your mind when new evidence emerges is a strength, not a weakness.

In this episode, Sarah and Laurel sit down with Dr. Stu Phillips, one of the world's most influential researchers in muscle physiology, protein metabolism, and resistance training. Together they discuss why Stu publicly challenged the idea that heavy lifting is required for bone density, what the evidence actually says about load and osteogenesis, and how newer research has changed the conversation around both muscle growth and bone health.

Stu explains why many long-held training beliefs—including the need for heavy weights for hypertrophy—have not held up under scrutiny, why good scientists must be willing to change their minds, and how concepts like effort and "progressive stimulus" may matter more than specific loading prescriptions.

The conversation also explores what researchers know (and still don't know) about bone adaptation, site-specific bone responses, impact training, mechanical loading, and the challenges of translating animal research into human recommendations. Finally, Stu shares his thoughts on protein obsession, exercise guidelines, weight loss stigma, and the importance of following the evidence wherever it leads.
