Kathryn Hansen is a recovery expert and author who provides educational resources for individuals struggling with bulimia and binge eating. Having published her foundational book Brain over Binge in 2011, she produces the Brain over Binge Podcast to teach brain-based recovery techniques that prioritize neuroplasticity over long-term psychotherapy. Hansen utilizes her platform to challenge traditional disease models of eating disorders, instead framing recovery as a mechanical process of deprogramming primitive brain responses. She frequently collaborates with health professionals in specialized editions like the Food Noise series and the Coaching Notes segments to offer technical yet accessible advice. Her recent work includes the listener companion Podcast Guide, which helps users navigate over 200 episodes of structured recovery content. Industry professionals recognize her for adapting the Rational Recovery model into a nutritional context, creating a standard framework used by outpatient programs to address the biological habits behind out-of-control eating through self-empowerment and higher cognitive functions.
