GNL Guides: Self-discovery and experimentation

Overview

This section is where you move beyond survival and start learning how to thrive with type 1 diabetes.

Before coming here, it’s essential to have solid foundations in type 1 diabetes management. If you haven’t already, complete the Foundations first. That work is non-negotiable — it’s where safety, competence, and baseline control are locked in.

Once Foundations are in place, you’ve earned the ability to survive safely.

This hub is about what comes next: learning how to thrive.

How to use this section

Thriving with T1D doesn’t come from a single protocol or a fixed endpoint. It emerges from an ongoing loop, with CGM as your teacher and real life as the testing ground:

Experiment → Learn → Adapt → Repeat

There is no single “right” way to live with type 1 diabetes. Some people prioritise steadiness and minimal cognitive load. Others want to explore performance, flexibility, sport, food, or physiology more deeply.

You do not need to do everything here. Most people shouldn’t. Instead, think of this page as a hub you return to as your life, goals, and capacity evolve.

Bookmark it. Come back to it. Use it to choose the next experiment — not to overwhelm yourself.

And if you want guidance as new tools and ideas are added, stay connected via the GNL Weekly Brief.
