Please note this episode of Type 1 on 1 contains honest discussion of severe depression at around 1'08", including suicidal thoughts. 

No matter how long you’ve been living with or close to type 1 diabetes, it remains an incredibly complex condition to understand. And while there’s a wealth of information out there to dig into, knowing what to pay attention to can be just as daunting. 

John Pemberton is a diabetes technology consultant, children’s dietician, researcher and has been living with type 1 diabetes himself for around 20 years. 

So if you’re looking for research-backed information about the right insulin pump, want to know why 20 minutes of walking is the magic key to a stubborn high glucose reading, or you just need to start with the basics without getting overwhelmed, his diabetes education platform The Glucose Never Lies could be the answer. 

It was created after his young son Jude tested positive for diabetes antibodies, and when it comes to distilling complicated diabetes information and making it make sense, John is a master of the craft.

In this episode we cover an incredible amount - from the professional, including his work with newly diagnosed families, the latest in diabetes research and his love of continuous glucose monitoring, to the deeply personal, including how years of undiagnosed ADHD led to severe depression and suicidal thoughts. After getting the right treatment in July 2025, John has found renewed purpose in taking The Glucose Never Lies to the next level.
