Today’s episode of The Drive is a rebroadcast of the conversation with Sarah Hallberg (released on May 17th, 2021). It's with great sadness that we report that Sarah recently lost her battle with lung cancer, and as such we've decided to republish her episode to honor her amazing work in challenging the status quo in the treatment of metabolic disease.
Sarah Hallberg was the Medical Director at Virta Health and a physician who spent nearly two decades treating patients with obesity and type 2 diabetes. In the first half of this episode, Sarah discusses how she became a huge believer in the efficacy of carbohydrate restriction for the treatment of type 2 diabetes through her research and clinical experience. Sarah challenges the common beliefs about the role of dietary fat and carbohydrate on the plasma makeup of fatty acids and triglycerides. She also expresses the importance of understanding early predictors of metabolic illness—highlighting one particular fatty acid as the most important early predictor—before finishing with a discussion about how doctors might be able to personalize patients’ metabolic management in the future. In the second half of this episode, Sarah tells the personal story of her own lung cancer diagnosis. She talks about dealing with her grief, deciding to continue her work while prioritizing her family, and how she devised a plan to extend her survival as long as possible.
