The Dr. Gabrielle Lyon Show

Protein has become a numbers game, and the numbers leave out the essential amino acids your muscle, brain and metabolism depend on. Protein is how you get them, and its quality may change how well you age.
In this episode, Dr. Gabrielle Lyon brings together some of her favorite moments with Dr. Don Layman, Dr. Heather Leidy and Dr. Jess Gwin to break down the essential amino acid requirement, cut through the confusion on protein quality (what a protein label leaves out, plant vs. animal sources, branched-chain amino acids, and leucine), and explain what the research says about essential amino acids in brain function, mood, sleep, energy deficit, and anabolic resistance as we age.
If you have ever wondered what your protein label isn't telling you, or why half an ounce of nuts and an ounce of lean beef count as the same serving, this conversation offers a clear, practical look at what the science says.

Eating before bed: harmful or helpful? Dr. Mike Ormsbee breaks down protein before bed, casein vs. whey, fat metabolism, sleep, and resistance training for postmenopausal women.
Late-night eating comes with many rules of thumb, and most people follow them without knowing what the research shows. Dr. Mike Ormsbee, a researcher at Florida State University, has spent years measuring how protein before bed affects metabolic rate, overnight fat burning, sleep, and recovery. If you lift, want to keep muscle as you age, or have been told to stop eating after dinner, his view on casein vs. whey and bedtime snacks may change what you keep in the kitchen.

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.
