Fasting Without the Stress with Renee Fitton

In today's episode of the Healthy Hustle Podcast, we're joined by Renee Fitton, MS, RD, a longevity dietitian and Director of Education at ProLon®, the company behind the revolutionary fasting-mimicking diet (FMD). With a master's degree in Healthspan and Longevity Nutrition from USC and years of experience working alongside leading longevity researcher Dr. Valter Longo, Renee breaks down everything you think you know about fasting—and introduces an approach designed for real-life sustainability. We explore how FMDs are different from water-only fasting or intermittent fasting, why they work particularly well for women over 40, and what it actually looks like to "fast with food." Whether you're navigating menopause, insulin resistance, fatigue, or just want to support healthy aging, this episode gives you science-backed strategies that are practical, sustainable, and deeply transformative. If you're curious about autophagy, metabolic flexibility, and how to reverse biological age without starving yourself—this one's for you.
