In December of 2018 Dr. Hallberg delivered this talk at a CrossFit Health event at CrossFit Headquarters.

Hallberg spoke about the unscientific and harmful practices that motivated her to change her career path, practices specifically pertaining to the management of obesity and Type 2 diabetes (T2D). She also outlined the physiological problems inherent in treating T2D with insulin, the benefits of treating the disease with a carb-restrictive diet, and the data from a Virta Health study that demonstrates the positive metabolic effects of carb restriction.
