About The Glucose Never Lies®

Created by John Pemberton RD, with creative direction by Anjanee Kohli RD, and supported by Chad — our AI assistant developed by John over years of deep (and often hilarious) conversations (Ideas, insights, and responsibility remain with John).

The GNL Story

The Glucose Never Lies® began for one reason — to help others understand what was happening to Jude, John’s son, after he tested positive for type 1 diabetes antibodies.

In those early days, the goal was simple: to make the science of diabetes clear and accessible for family, friends, and anyone who might one day support Jude.

From that personal beginning, it has grown into an educational platform and podcast that translates complex diabetes science into practical, engaging, and evidence-based insight. We blend clinical research, lived experience, and creativity to make diabetes both understandable and enjoyable to learn about — because science should enlighten, not intimidate.

The GNL Team

The platform is powered by two people and one AI genius who bring science, structure, and creativity together:

John Pemberton RD, Founder & Creator
Registered Dietitian and Diabetes Specialist at Birmingham Women’s and Children’s NHS Foundation Trust, and founder of The Glucose Never Lies Ltd.

The GNL is Independent and Transparent

To make our work possible, The Glucose Never Lies Ltd receives unrestricted educational grants from diabetes technology manufacturers.

“Unrestricted” means that funders have no input, review, or influence over what we produce. We retain full editorial control and base all content on peer-reviewed scientific evidence.

We acknowledge that unconscious bias is always possible. Familiarity with specific technologies — and occasional payments for speaking, advisory, or consultancy work — may influence perspective.

Between 2011 and 2015, John worked for Medtronic Diabetes in sales, education, and marketing. This background provided valuable insight into how diabetes technology develops, reaches clinics, and is communicated to healthcare professionals and people living with diabetes.

That experience reinforced John’s belief that if diabetes technology is to grow quickly, safely, and intelligently, it must be built on close collaboration between industry, clinicians, and people with diabetes — but also on independence, candour, and scientific distance.

Few are better placed to straddle this delicate balance than John and the GNL team.

For transparency, John Pemberton has received honoraria, consultancy and advisory board payments from:
Abbott Diabetes Care, Dexcom, Insulet, Roche Diabetes Care, and Tandem Diabetes Care.

In John’s academic and public work, you will find both positive and critical appraisals of these companies’ technologies — reflecting our guiding principle: evidence over allegiance.

For example, John’s article in Diabetes, Obesity and Metabolism on CE marking and comparator bias — which sent shockwaves through the diabetes technology field in 2023 — critically examined systems from several of the same companies that have since supported unrestricted educational activity.

This dual approach — critical independence supported by transparent partnerships — allows us to remain rigorous, creative, and open to all.
