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.

Welcome to The Glucose Never Lies podcast
In today’s episode, we explore a game-changing approach to glucose control—activity snacking. If you’ve ever struggled with post-meal spikes, found insulin too slow to bring down highs, or wondered how movement could help stabilise your blood glucose, this episode is for you.
I’ll be sharing the latest research on how small, frequent movements can supercharge insulin, improve time in range, and reduce glucose highs without the need for extra insulin corrections. We will discuss practical strategies such as the “3 every 30” method, which involves moving for three minutes every 30 minutes to maintain stable glucose levels. We will also cover the benefits of walking before or after meals to prevent glucose spikes and introduce the “15 by 2” rule, a simple technique to lower high glucose levels faster than waiting for correction doses to take effect.
Stay tuned to the end to hear: 99 Problems, But High Glucose Ain't One
In addition to these strategies, I will break down groundbreaking studies that demonstrate the impact of movement on glucose regulation. Whether you are living with type 1 diabetes, supporting someone who is, or simply looking to optimise your health, this episode is packed with valuable insights that you can put into action immediately.
