The Science of Protein Cycling, Autophagy and Fat Loss with Vanessa Spina
In this episode, Dr. Jockers and Vanessa Spina break down new human research showing why high protein doesn't block autophagy when calories are low. You'll learn how this changes everything we've believed about protein timing, fasting, and cellular repair. The conversation also reveals why prioritizing protein can accelerate fat loss without sacrificing muscle.  You'll hear how protein impacts appetite, hormones, and metabolic flexibility—and why many people overeat simply because they're under-consuming essential amino acids. Vanessa explains the protein leverage effect and how it naturally reduces cravings, stabilizes blood sugar, and makes eating "effortlessly" satisfying. These insights can help you rethink how you build your daily meals.  You'll discover why certain fasting styles can increase visceral fat loss, support hormonal balance, and boost performance. Expect a mix of science, real-world application, and surprising findings you may not have heard before.   In This Episode: 00:00 Introduction and Exciting New Study 00:21 Welcome and Guest Introduction 00:30 Deep Dive into the New Study 01:52 Vanessa Spina's Expertise and Background 05:47 Interview with Vanessa Spina Begins 06:15 Discussion on Protein Absorption Study 14:04 Personal Experiences with Protein and Fasting 16:55 Debunking Protein Myths 18:10 Nutrition Principles and Protein Prioritization 22:23 Ketones, Satiety, and Inflammation 27:07 Balancing Hormones and Stress 31:17 Understanding Autophagy and Protein Intake 32:35 The Importance of Human Trials in Research 35:11 Study on High Protein Fasting Mimicking Diet 38:38 Results and Implications of the Study 42:18 Personal Experiences with Protein-Sparing Modified Fasting 45:32 Practical Tips for Implementing Protein-Sparing Modified Fasting 57:54 Comparing Different Fasting Approaches 01:01:13 Conclusion and Final Thoughts  Hydration is one of the fastest ways to boost your energy, sharpen your focus, curb cravings, and even improve the look and feel of your skin — but water alone isn't enough.
