Susan Peirce Thompson, Ph.D., went from a drug-addicted teenager to a food-addicted young woman. In a quest to reclaim her life, she got clean, stopped eating sugar and flour, and went from size 16 to size 4. Now, as a Professor of Brain and Cognitive Sciences, President of the Institute for Sustainable Weight Loss, and CEO of Bright Line Eating, she and her team are on a mission to help one million people achieve long-term, sustainable weight loss by 2030. Susan's program utilizes cutting-edge research to explain how the brain blocks weight loss. Every day, she teaches people how to undo that damage so they can lose excess weight and truly find peace with food. She’s the author of multiple New York Times best-selling books, including the landmark Bright Line Eating. Her latest book is On This Bright Day: A Year of Reflections for Lasting Food Freedom.
