How do you build real longevity without getting trapped in extreme protocols or daily routines that drain you instead of helping you?

In this episode of Habits & Hustle, I sit down with a dietitian with a Master’s in Longevity Nutrition to talk about what actually supports aging well. We look at simple, practical strategies that make your body stronger instead of pushing it into burnout.

We get into why fast-mimicking works so well, how it triggers real cellular repair, and why short, focused cycles beat everyday restriction. We also talk about muscle protection, what women in midlife need to pay attention to, and the metabolic shifts that happen when you stress the body the right way.

Renee Fitton is a longevity dietitian with a Master’s in Longevity Nutrition and VP of Growth at ProLon. She brings a decade of experience in evidence-based nutrition and real-world strategies that help people build a healthier, stronger future. Tune in.
