The Glucose Never Lies® Podcast

The GNL Podcast is structured around three core themes, designed to bring clarity, curiosity, and conversations that actually matter in Type 1 diabetes.

Theme 1: Lifestyle and Type 1 diabetes
Understanding why the glucose system behaves in unpredictable and sometimes frustrating ways — and how to work with it, not against it. This includes applying evidence-based nutrition, physical activity, and exercise strategies, alongside the less discussed but equally real factors such as alcohol management, pregnancy, and mental cycles.

• Episode 7 — Fundamentals of The GNL
• Episode 8 — Activity Snacking for TIR
• Episode 14 — Insulin Resistance & T1D
• Episode 15 — C-Peptide & T1D
• Episode 16 — Driving: 5-to-Drive
• Episode 18 — Exercise without fear
• Episode 25 — Partying with T1D

Theme 2: Technology and drugs in Type 1 diabetes
Clear, grounded discussion of the tools that actually move the needle: CGM, automated insulin delivery, GLP-1 and other glucose-lowering agents, and emerging therapies that are shaping real-world Type 1 care right now.

• Episodes 1 – 6 — AID Systems Guide
• Episodes 10 – 12 — CGM Series
• Episode 17 — GLP-1 in Type 1 Diabetes
• Episode 24 — T1D Skincare & Control-IQ

Theme 3: Beyond the numbers
Because data, technology, and education only take you so far. This is about the human layer: community, emotional support, identity, and building a life that isn’t permanently glucose-centred — but still works with diabetes rather than pretending it isn’t there.

• Episode 21 — SPARK: Five-to-Drive-Change
• Episode 22 — CGM Access Blueprint
• Episode 23 — Brunches to Bali
• Episode 26 —Community & Vulnerability
• Episode 27 — T1D Looping Blind

Here is the deeper dive.

I’m John Pemberton — diabetes educator, researcher, and dad — living with type 1 since 2008.

I started The Glucose Never Lies® when my son tested positive for T1D antibodies. I wanted the resource I wish I’d had on day one: clear, practical, evidence-led guidance.

On the podcast, I sit down with world-class clinicians, researchers, and people with lived experience to translate the latest science into useful action. We go deep on tech, physiology, and day-to-day decisions: how to use CGM and AID well, balance nutrition, exercise and sleep, and still live a full, fun life — parties, sport, adventures and all.

Why a podcast? Long-form conversation captures the nuance that written guides can miss. I’ve learned that from shows like Peter Attia’s The Drive. This is that same spirit, focused on type 1 diabetes — bringing together lived experience, professional practice, and cutting-edge research you can actually use.

What you’ll hear

• The latest evidence made actionable
• Honest conversations on getting more from CGM, pumps, and AID
• Practical ways to balance food, movement, sleep, and real life
• Lived experience — sport, parties, travel, and everything in between

“Thank you so much for your podcasts on the various pumps. This has helped us find the right one for my son and, more importantly, gave us the knowledge we needed to have an informed conversation with our amazing care team and explain the features that were right for us.” Karine, mum of a wonderful son who lives with T1D.
