Insulin Resistance: How Poor Diet Fuels Diabetes & Long-Term Health Risks

In this episode of Decoding Health, Dr. Urban breaks down the growing prevalence of insulin resistance and type 2 diabetes, particularly in younger generations questioning standard American dietary habits. He explains how insulin resistance develops over decades, driven by poor diet, lack of exercise, ectopic fat buildup, and excessive seed oil consumption. Dr. Urban discusses how type 2 diabetes results from the body’s inability to properly use insulin, highlighting two scientific perspectives on glucose uptake failures at the cellular level. He emphasizes that lifestyle changes—especially reducing sugar and seed oils, adopting low-carb diets like keto or carnivore, and incorporating resistance training—can significantly reverse or halt progression toward diabetes. Dr. Urban encourages proactive health decisions and dispels the myth that the science on diabetes is fully settled.
