Dr. Susan Peirce Thompson: The Surprising Psychology of Keeping Weight Off Forever

What if the real challenge isn’t losing weight… but keeping it off?

In this powerful interview, Susan Peirce Thompson, PhD—adjunct associate professor of brain and cognitive sciences, bestselling author, and founder of Bright Line Eating—breaks down the surprising psychology of weight loss maintenance and why so many people regain weight even after making progress.

Most programs focus on short-term weight loss. But lasting success comes from learning how to maintain your results without living in constant food obsession, diet mentality, or the exhausting cycle of starting over.

In this episode, we explore the three deep identity shifts that make long-term weight maintenance possible. We also discuss the psychology behind food addiction, why ultra-processed foods hijack the brain, and what it takes to build a sustainable eating plan in today’s modern food environment.

If you’ve ever felt stuck in the dieting merry-go-round, struggled with food noise, or wondered why weight loss doesn’t last—this conversation will change how you see the journey.

In this episode, you’ll learn:
• Why weight loss maintenance is the missing piece of the conversation
• The psychology of keeping weight off long-term
• How to stop the constant mental battle with food
• Why willpower isn’t reliable (and what works instead)
• The identity framework behind lasting transformation
• How to move from dieting → to a sustainable lifestyle
• Practical strategies to maintain weight without obsession

Whether you're still trying to lose weight or you’ve already lost weight and want to keep it off, this episode is about creating a life where you feel free, peaceful, and stable—not constantly gaining and losing.
