Why You Know What to Do, But Still Don’t Do It

The Dr. Hyman Show

Lasting change begins with a shift in both mindset and behavior. Many people remain stuck in self-defeating patterns because of unconscious narratives, emotional triggers, and a disconnection from their body’s inner wisdom. Change isn’t just about willpower or information—it’s about learning to rewire the brain through small, intentional actions that generate powerful emotional feedback loops. Identity transformation happens not through repetition, but through experiences that create a sense of success. In a world flooded with conflicting advice and manipulative marketing, reclaiming agency requires tuning into your own signals, building self-trust, and recognizing that behavior change is a design challenge—not a character flaw. Empowerment comes from realizing that the ability to change is built into who we are as humans.

In this episode, I speak with Tom Bilyeu, Dr. Rangan Chatterjee, and Dr. BJ Fogg about cracking the nut of behavior change.

Tom Bilyeu is a filmmaker and serial entrepreneur best known as the co-founder of Quest Nutrition, a billion-dollar company built to combat metabolic disease through value-driven innovation. After nearly a decade of chasing financial success and feeling unfulfilled, he realized the importance of loving the struggle itself. This insight led him and his partners to shift focus from profit to purpose. Quest quickly became the second fastest-growing company in North America, according to Inc. Magazine. After achieving significant personal wealth, Tom turned to the other global crisis he saw—disempowering mindsets. To address this, he co-founded Impact Theory, a media studio with his wife, Lisa Bilyeu. Their mission is to scale mindset transformation by producing empowering content that shifts the cultural subconscious. Just as Disney built the most magical place on Earth, the Bilyeus aim to build the most empowering one.

Dr. BJ Fogg is a behavior scientist, author, and founder of the Behavior Design Lab at Stanford University, where he has researched human behavior since 1998. He developed the groundbreaking “Behavior Design” system, which explains how behavior works and how to design it effectively. Over the past decade, his lab has focused on practical applications—from helping people navigate coronavirus-related challenges to training climate change professionals in behavior change strategies.
