5 ways to control your blood sugar, reverse insulin resistance, and reduce your heart disease risk

Professor Rob Semple explains how insulin resistance — a condition affecting roughly 1 in 4 people — quietly raises the risk of heart disease and cancer, often with no change in blood sugar and no obvious symptoms. The episode covers what insulin does, why its absence was once fatal, how resistance progresses toward type 2 diabetes, and five practical strategies for regaining insulin sensitivity: managing weight (especially visceral fat), using exercise strategically, reducing stress, prioritizing sleep consistency, and recognizing that rapid post-meal blood sugar drops can be an early warning sign. Semple also discusses visible skin signs of high insulin and why generic online symptom lists are often misleading.
