Type 1 diabetes isn’t static. It’s a moving target.
It’s shaped by ever-changing biology, behaviour, mindset, stress, sleep, hormones and environment.
The idea that one plan works for everyone is a fantasy.
The Glucose Never Lies® exists for one purpose: to give people with type 1 diabetes — and those who support them — a clear, evidence-informed framework for self-discovery, grounded in what actually happens in real life.
Our philosophy;
The Glucose Never Lies
The glucose result is the only unbiased feedback loop in type 1 diabetes. It shows what works and what doesn’t — not what “should” work according to theory, algorithms or opinion.
Your response might sit anywhere on the spectrum of “expected”, and it can shift over time. That’s reality, not failure.
Glucose is information, not judgement.
Self-discovery and experimentation
Learn the ideas, try them safely with your healthcare team, watch the glucose, then adapt. This isn’t a doctrine. It’s a loop:
Experiment → Learn → Adapt → Repeat
There is no single right way to do T1D — only the way that works best for you. For some, that means safety and steadiness. For others, it’s deeper exploration.
Stay curious. Stay open. And keep learning with the GNL Weekly Brief.
Core education for self-discovery
- T1D Foundations (understanding T1D and how to survive)
- Dynamic Glucose Management (how to thrive)
- Mealtime Insulin Guide (dominating high-carb and high-fat meals)
- Exercise Guide (insulin on board is king — and how to stay in target)
Self-discovery key guides
- CGM Guide (how to think about accuracy and choose wisely)
- AID or HCL Guide (why they’re powerful, and their limitations)
- Partying with T1D Guide (how to stay safe and still enjoy life)
- Insulin Resistance with T1D Guide (why fat loss is harder with T1D)
- Children’s T1D Guides (under 5s to school holidays)

Why this platform exists
In 2019 our family received a call that changed everything: my son, Jude, screened positive for type 1 diabetes auto-antibodies. I combined my clinical work, research experience and nearly two decades of life with T1D to build the education resource I wished existed when I was diagnosed at 27.
Two months later, Jude’s confirmatory test was negative — a false positive, which happens around 5% of the time. Relief, yes. But the experience made one thing clear: families and adults with T1D need access to clarity, not noise.
This platform is built for them — and for you.
How the GNL evolved
From 2019–2022 the GNL grew organically: short bursts of research, writing, experimentation and honest conversations with the T1D community. In 2025, the GNL Podcast launched and brought the mission to life — making complex diabetes science accessible, practical and human.
Independence and funding
The Glucose Never Lies Ltd was incorporated in 2025, supported by world-class scientific advisors and a clear governance structure. The goal is simple: keep the information accurate, practical and free from commercial distortion.
The platform is powered mainly by the community — people with type 1 diabetes, parents, partners and supporters. If our work helps you, consider supporting it:

Here’s one example of the philosophy in action — Grace showing how a bit of movement can rapidly bring glucose back into range.
How is the GNL written?
Most sections have two layers. The first is written for people like my wife, Dani: clear, practical “how to” with minimal jargon. The second goes deeper into the physiology, psychology and data for those who want the underlying “why”.
You don’t have to read both. Take what you need, when you need it.
