Dr. Sarah Hallberg wanted to make a positive, lasting difference in her patients' lives. But when she collided with the chronically frustrating aspects of the American healthcare system - entrenched thinking, overreliance on meds, contentment to manage long-term conditions rather than seek root causes - she pursued a new way, and found it. At the weight loss clinic she led in Lafayette, Indiana, she discovered that the standard approach - a low-fat diet = weight loss and good health - had zero scientific support. Dr. Hallberg's clinic adopted a model of a low-carbohdrate, high-fat diet. Her patients lost weight. Those who also suffered from diabetes saw their condition improve or "go away." Over the next several years, Dr. Hallberg and her team embarked on a journey to study the health effects of the low-carb diet; their pioneering research led to their most crucial finding: Diabetes need not simply be managed but can be reversed by diet. While battling terminal cancer, Dr. Hallberg wrote this crucial, inspiring account of how we can all eat better to live better and longer. As important, this book - her first and last - is a searing indictment of what happens when we leave status quo thinking unchallenged, and how it impacts quality of life for us and those we love.
