The host
John is a diabetes educator, researcher, and dad — living with type 1 since 2008. He started The Glucose Never Lies when his son Jude tested positive for type 1 diabetes antibodies, wanting to create the resource he wished he had had on day one: clear, practical, evidence-led guidance.
On the podcast, John sits down with world-class clinicians, researchers, and people with lived experience to translate the latest science into useful understanding — topics ranging from CGM and AID to nutrition, exercise, sleep, and still living a full and fun life.
Long-form conversation captures nuance that written guides can miss. The GNL Podcast brings together lived experience, professional practice, and cutting-edge research — focused entirely on type 1 diabetes.
“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.”
— Karine, mum of a wonderful son who lives with T1DExplore the platform
