As a gastroenterologist, I believe that the gut is the gateway to good health. Common gastrointestinal conditions such as gastroesophageal reflux disease (GERD) and non-alcoholic fatty liver disease (NAFLD) may be managed effectively with a low-carbohydrate/high fat (ketogenic) diet. Many patients have positively transformed their health (inside and out!) by living a low-carbohydrate/high fat lifestyle. The Diet Doctor website is an outstanding resource that provides science-based guidance for patients and health care providers.
