Today, I'm joined by the insightful Ashley Koff, renowned registered dietitian and fierce advocate for personalized, realistic nutrition that actually works in the real world.

Today, I'm excited to bring back the always thought-provoking Joel Greene, author of "The Immunity Code" and "The Way," for a fresh conversation on why true longevity is about so much more than how much muscle you have or the latest diet trend you're following.

With the intensity of the holiday season winding down, I wanted to take a step back from the usual deep-dives and high-tech hacks to focus on something fundamental—free, practical strategies to help you manage stress.
