In this episode we explore the causes of insulin resistance, and the dietary modifications that may help those with insulin resistance.

We discuss how insulin resistance is a complex metabolic disorder, that goes beyond one single pathway or cause. There is also a discussion on the mechanisms of insulin resistance pathogenesis. Specifically, we talk about the accumulation of ectopic fat. Ectopic fat is the storage of triglycerides in tissues other than fat tissue, such as the liver, skeletal muscle, heart, and pancreas.

There is also an overview of the Twin-Cycle Hypothesis, which was discussed in more detail in a previous episode with Prof. Roy Taylor. In addition, we give special mention to liver fat accumulation and the relationship between insulin resistance and non-alcoholic fatty liver disease (NAFLD).

Then various diet interventions are assessed for their potential usefulness to those with insulin resistnace. This includes different diet types (e.g. whole-food plant-based diet, low-carbohydrate ketogenic diet, etc.), role of macronutrients, pre-loading studies, and the role of meal timing and circadian effects.
