Living With Intention and Building Plant-Based Muscle After 50 with Dr. Rich Rosenfeld

What if your best body, clearest mind, and strongest sense of purpose were still ahead of you?

That’s the question I explore in this episode with Richard Rosenfeld, MD, MPH, MBA. He’s a board-certified ENT, Director of Guidelines and Quality at the American College of Lifestyle Medicine, and one of the most published ENT researchers in the world—with nearly 400 peer-reviewed articles to his name.

But what really sets Rich apart is his personal story.

In his mid-50s, he hit a turning point—and decided to change course. He adopted a whole food, plant-based lifestyle. Picked up strength training again after decades off. Started running. Now, in his 60s, he’s finished 10 marathons, lifts consistently, and says he feels sharper and more alive than ever.

In This Episode, We Dive Into:

• What sparked Rich’s midlife transformation

• How he fuels, trains, and recovers today

• Strength training after 50 and the role of protein and creatine

• His honest take on GLP-1 meds (like Wegovy and Zepbound) for weight loss

• And how mindset, curiosity, and purpose fuel long-term change

We also talk about the culture of medicine—and what it’ll take to build a system that actually supports health, not just disease management.

This conversation is full of science-backed insight and lived experience. And it’s a story that reminds you what’s possible—no matter your starting point.
