Why Most People Are Insulin Resistant (It's Not What You Think) | Dr. Sarah Myhill
Sarah Myhill is a UK clinician known for her work on chronic fatigue syndrome (CFS). In this interview she pushes a 'mitochondria-first' interpretation of insulin resistance: the body becomes insulin resistant because the cellular power plants can't process fuel efficiently, and chronic carbohydrate excess overwhelms an already-fragile system. Her recommended template is paleo-ketogenic, with fasting, magnesium, B-vitamins, and CoQ10 (coenzyme Q10) layered on top. Some of this is mainstream (refined-carb avoidance, fasting, the link between metabolic dysfunction and fatigue). Some is more contested (mitochondria-first ordering, supplement protocols at the doses she recommends, generalizability beyond her CFS patient population). Heavy reliance on clinical experience over evidence from randomized controlled trials (RCTs). Useful for hypothesis-generation, less reliable for prescriptive guidance for the general population.
