Blood glucose is easy to measure, but not always easy to interpret. This Premium-only episode brings together insights from several previous guests to examine blood glucose responses in more detail.

We discuss the misuse of clinical thresholds, the difference between OGTT results and free-living CGM data, and whether "flatter" glucose curves are actually better in normoglycemic people.

The episode also covers when repeated high glucose excursions may be worth investigating, how sugar intake should be interpreted in context, and why skeletal muscle and exercise play such an important role in glucose regulation.

Overall, the aim is to clarify what glucose responses can tell us, what they cannot tell us, and how to avoid pathologizing normal physiology.

Sigma Nutrition Radio, hosted by nutrition scientist Danny Lennon, moves beyond the noise of diet trends and simplistic advice to explore the complex, fascinating world of human nutrition. This is a space for deep, evidence-based conversations that acknowledge the nuance and often contradictory nature of scientific research. Each episode delves into a specific topic within health, fitness, or dietetics, breaking down the underlying physiology, examining the latest studies, and discussing practical implications with expert guests. The goal isn't to hand out rigid meal plans but to cultivate the critical thinking skills necessary to navigate the ever-changing landscape of nutritional science. You'll hear detailed analyses of how research is conducted, thoughtful debates on contentious issues, and explorations of how evidence translates-or doesn't-into real-world recommendations for different individuals. Tuning into this podcast means committing to a more sophisticated understanding of how food, movement, and metabolism interact, leaving you better equipped to make informed decisions about your own health and skepticism towards the next big headline. Danny’s approach is both rigorous and accessible, making even the most detailed biochemical pathways relevant to everyday life. It’s for anyone who has ever wondered about the real story behind a nutrition claim and values substance over soundbites.
