The Food Relationship Lab For Dietitians
In this episode, we revisit the autonomic nervous system, shifting the focus from the polyvagal theory to the foundational sympathetic and parasympathetic systems. I share my personal realization from neuroscience classes—where polyvagal theory wasn’t even mentioned!—and dive into how our stress response shapes behaviors like stress eating or stress fasting. We explore the fight-or-flight response, its physiological goals (mobilizing energy, shutting down digestion, increasing alertness), and how acute vs. chronic stress impact hunger. I also break down the SAM system and HPA axis, explaining how adrenaline and cortisol influence metabolism, blood pressure, and even memory. Most importantly, I unpack why stress eating actually works to dial down the sympathetic response—and why that doesn’t make you broken or weak. Instead of shame, this understanding gives you insight and a chance to respond with effective tools beyond food. This is part of an online workshop I have been invited to give on March 21st.
