Dr. Tommy Wood: Can Cognitive Decline Be Reversed?

Childhood and adolescence provide a one-time biological opportunity: our kids' bodies are primed to grow, build tissue, and develop cognitive capacity. But to do that, they need the right raw materials. In this video, we break down why restricting nutrient-dense foods in growing children puts their development at risk. We explore the critical role of highly bioavailable nutrients like heme iron and vitamin B12, how nutrient status directly impacts academic performance and attention, and why building muscle and metabolic reserve early protects your health decades later. Don't wait until your children are 40 and struggling with their health to teach them what strong looks like.

What you choose to eat is the single most important decision you make every day—impacting your metabolic health, your family, the economy, and the future of our food supply. In this episode, world-renowned cardiologist and nutrition expert Dr. Dariush Mozaffarian breaks down the "Food is Medicine" movement, cuts through dietary confusion (fats vs. carbs, food label marketing, and ultra-processed ingredients), and reveals how public demand, science, and policy can repair a broken food system. If you have ever felt overwhelmed in the grocery aisle or wondered how to separate real nutrition science from industry marketing, this conversation provides a clear, practical roadmap.

Protein is in everything right now: coffee, chips, cookies, bars. But despite the massive marketing hype, the world’s leading scientists are still debating fundamental questions about how much protein we actually need and how the body uses it. Fresh off the Protein Summit 3.0 at Texas A&M, Dr. Gabrielle Lyon breaks down what top researchers agreed on, why treating protein as a single number is a major mistake, and how to stop falling for "high-protein" health halos in the grocery store.

In this episode, board-certified anesthesiologist, researcher, and former Real Housewives of Dallas star Dr. Tiffany Moon pulls back the curtain on modern medicine, surgical pain management, and the reality of navigating elite academia. From addressing widespread public fears around clinical fentanyl use to detailing why she was branded an "embarrassment" by academic peers for appearing on reality television, Dr. Moon speaks candidly about breaking stereotypes, the gender pay gap in healthcare, and using a massive public platform to advocate for science and mentorship.

Can you tell someone's testosterone or estrogen levels just by looking at their face? Is "jawmaxxing" actually backed by science? In this video, we dive deep into the real science of hormones, physical attraction, and evolutionary biology. We debunk popular myths around high testosterone, facial masculinity, and ovulation preferences, revealing what the research actually shows about human mate selection. Discover why facial structure isn't a hormone panel, how estrogen impacts skin and collagen as women age, and why physical strength accounts for 70% of perceived bodily attractiveness. If you want to understand how hormones shape our development—and why muscle is the single most modifiable signal of health and longevity—this episode is for you.
