The LynchPin Podcast with Nora
Health transformations often begin with a wake-up call — and for Peter Megdal, that call came from his own heart. After receiving a diagnosis that forced him to confront the state of his health, Peter began questioning everything he thought he knew about food, science, and wellness. What started as a personal effort to heal his heart evolved into a deeper mission to help others make informed, sustainable choices for lifelong vitality.
In this episode of The Lynchpin Podcast, Nora sits down with Peter Megdal, PhD, a nutrition researcher, educator, and world-record-holding cyclist whose work bridges scientific rigor and personal experience. After years in the pharmaceutical and biotech sectors, Peter faced a heart disease diagnosis that pushed him to question the very systems he once trusted. Through extensive research and experimentation, he discovered how nutrition, medicine, and lifestyle choices can work together to restore long-term heart health.
Peter shares what his research taught him about how food impacts inflammation and energy, why scientific studies often present conflicting results, and how funding sources can influence what we believe about health. He also opens up about the mindset shift that helped him move from fear to empowerment, transforming his diagnosis into a blueprint for balance, curiosity, and purpose.
If you’ve been feeling the pull to take charge of your health, reexamine what you’re putting into your body, or simply understand how science meets real life, this conversation will inspire you to take small, informed steps toward a stronger, more intentional you.
