In this episode of Peptides and Longevity, Michael McNeal sits down with Melanie Murphy Richter to break down how the ProLon 5-Day Fasting Mimicking Diet is designed to keep you just below key nutrient-sensing pathways so you can access autophagy, support gut balance, and reduce cravings while still eating real food. Melanie Murphy Richter, MS, RDN, is a registered dietitian nutritionist with a background in healthcare PR and a master’s degree in health span and longevity. She runs a private practice focused on gut-centered care for a wide range of conditions, including autoimmune concerns, anxiety, and depression. She is also the Director of Communications at L-Nutra, a longevity science company behind the ProLon 5-Day Fasting Mimicking Diet. Having studied under Valter Longo and completed numerous ProLon cycles herself, Melanie blends clinical insight with practical experience to help people understand fasting science in a way they can actually follow.
