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.
