As the founder of The Better Nutrition Program, Nutrition Course Director at UC Irvine’s Integrative Health Institute, and faculty member at IFNA, Ashley brings a depth of clinical and practical insight that few can match. Her new book, Your Best Shot, tackles one of the most talked-about questions of our time: Is the GLP-1 shot your best shot—or not? But this is far from a book about medications. Instead, Ashley reframes the entire conversation around personalization, body-ecosystem thinking, and the liberating shift from perfectionism to her signature philosophy: better, not perfect. In our conversation, Ashley explains why most people aren’t struggling with a lack of knowledge, but rather an overwhelming flood of it, something she calls “INFObesity.” She discusses the Switch Framework she developed to help individuals identify the key metabolic levers that matter most for them, and she shares compelling patient stories that demonstrate how real transformation happens when we align nutrition and lifestyle choices with our unique biology. What emerges is a far more hopeful, empowering narrative about weight-health, one that acknowledges the complexity of modern life while giving us practical tools to navigate it. If you’ve ever felt frustrated or confused by the conflicting messages around diet, GLP-1 medications, metabolism, or weight-loss strategies, this episode is an essential listen. It offers clarity, compassion, and a science-based path toward truly optimal health. ==== 0:00 Intro 3:39 Misinformation in the world of weight loss 8:28 Calories in vs calories out 12:52 The importance of satiety related hormones 18:10 The experiment of GLP-1 24:49 Ad: Optoceutics 26:37 GLP-1 agonist drugs and the brain 37:16 Ad: Fresh Pressed Olive Oil Club 40:27 GLP-1 and mental health 50:02 Disconnect between food policy and obesity solutions 55:09 Conclusion ==== Ashley Koff, RD is the founder of The Better Nutrition Program (BNP), the Nutrition Course Director for UC Irvine’s Susan Samueli Integrative Health Institute's Integrative and Functional Medicine Fellowship, and a faculty member at the Integrative and Functional Nutrition Academy (IFNA), where she teaches “An Integrative and Functional Nutrition Approach to Obesity and Weight Management.” She is also the author of the upcoming book, Your Best Shot (Harper One, January 6, 2026). A practitioner for over 25 years, Koff is leading a transformative movement in personalized nutrition, turning “better, not perfect” choices into practical, sustainable strategies that deliver real health outcomes.
