Why Physiology and Nervous System Overlap Matters

Send us a text

This week on the Less Stressed Life, Eliza Kingsford joins me to talk about how your nervous system drives behavior and why lasting change only happens when your body feels safe.

We dive into the three main nervous system states (safe and connected, activated, and shutdown) and how they show up in your relationship with food, stress, and self-control. Eliza explains why willpower isn’t the problem and how to build capacity with daily “deposits” like rest, nourishment, and connection so your body can finally support change instead of resist it.

I was fired up about this one because it connects everything—physiology, behavior, and peace. You’ll walk away with a clearer understanding of why you feel stuck and how to shift it.

KEY TAKEAWAYS:
• Your nervous system drives every thought, feeling, and action
• Change feels unsafe to the brain—safety cues make new habits possible
• Food behaviors mirror nervous system states (frantic in activation, numbing in shutdown)
• Build capacity by balancing “deposits” like rest, nourishment, and connection with “withdrawals” like stress and overwork
• Flexibility and resilience in your nervous system create real, lasting change
