Mr. John Pemberton
Birmingham Women's and Children's Foundation Trust, Birmingham
John Pemberton, BSc (Hons), PgDip, RD is a UK-based diabetes dietitian, technologist, and person living with type 1 diabetes, working at the interface of physiology, technology, and real life. He is Lead Paediatric Diabetes Dietitian at Birmingham Women’s and Children’s NHS Foundation Trust and an international contributor to CGM and automated insulin delivery (AID) standards through IFCC, ISPAD, EASD, and EXTOD.
John specialises in translating complex diabetes technology—CGM, hybrid closed loop, and exercise physiology—into practical, testable frameworks that people can actually live with. He is co-author of the ISPAD 2022 and EASD 2024 Exercise Guidelines and a leading voice on CGM performance, safety, and regulation in Europe.
He founded The Glucose Never Lies®, an independent education platform focused on dynamic glucose management, structured self-experimentation, and evidence-based challenge to consensus when it drifts from lived reality. His work blends modern algorithms with old truths: regular meals, daily movement, post-meal activity, and humility in the face of biology.
At heart, John builds systems that reduce cognitive load, restore agency, and make diabetes management clearer, safer, and more human.
