#209 - What is insulin resistance and why does it matter? | Dr. Rob Lustig & Dr. Dominic D’Agostino

Insulin resistance is when cells stop responding to insulin’s signal to uptake glucose. It’s a hallmark of prediabetes, Type 2 diabetes, and other forms of metabolic dysfunction, and it manifests as several chronic disease, ranging from Alzheimer’s to polycystic ovarian syndrome. Dr. Rob Lustig and Dr. Dominic D’Agostino discuss the importance of monitoring insulin levels, why a high or increasing insulin level is a problem, and how insulin resistance hinders weight management.
