The Glucose Never Lies® Podcast
Host John Pemberton — diabetes educator, researcher, and dad living with type 1 since 2008 — explores how to think clearly about type 1 diabetes in the real world.
Each episode translates current evidence and expert practice into decisions you can use: CGM accuracy and interpretation, getting more from pumps and automated insulin delivery, movement as a glucose tool, nutrition that protects performance and enjoyment, sleep, travel, parties, and sport.
Guests include leading clinicians, researchers, and people with lived experience. Expect respectful challenge, plain language, and practical take-aways.
Note: Educational only. No therapeutic relationship or personal medical advice.
