Your Brain Is Designed to Regain Weight - Here’s How to Outsmart It | Susan Peirce Thompson (Bonus Episode)

What if lasting health has less to do with willpower - and more to do with identity, environment, and the systems we create around ourselves?

In today's episode, I’m joined by Susan Peirce Thompson to discuss her new book, Maintain: The Three Identity Shifts that Turn Temporary Weight Loss into Lasting Freedom, and the deeper realities behind lasting behavior change. Susan shares her personal history with addiction, obesity, and creating Bright Line Eating, while explaining why long-term weight struggles are often rooted more in brain chemistry and hormones than willpower alone.

Together, we explore food addiction, habit formation, emotional coping, the overstimulation of modern life, and the three identity shifts Susan believes are necessary for sustainable freedom. We also discuss the role of ultra-processed foods, leptin resistance, GLP-1 medications, and what it looks like to pursue health from a place of intention rather than obsession.
