New Financial Year, New You – Five Behaviour Change Principles for Type 1 Diabetes

April marks a fresh start. Not just for budgets and spreadsheets – but for how you look after yourself. Vanessa Haydock, behaviour analyst and T1D coach, explains five principles that make change actually stick.

TLDR

The new financial year is the perfect moment to reset – not with dramatic overhauls, but with small, deliberate nudges. In GNL Podcast Episode 29, Vanessa Haydock laid out five principles for sustainable behaviour change with type 1 diabetes: design your environment, use cues instead of willpower, reduce the threat level, choose accountability that fits you, and build safe community. The good news? Vanessa has streamlined her own admin processes and now has coaching spots available to help you put these principles into action.

April: the other New Year

January gets all the credit for fresh starts, but April is arguably a better one. The days are longer. The clocks have changed. The financial year has just turned over. And if you work in health, education, or public services, April is when new plans, new budgets, and new energy land on your desk.

So why not apply the same logic to how you manage your health?

Not a dramatic overhaul. Not a punishing new regime. Just a small, deliberate shift – the kind that sticks because it is built around how humans actually behave, rather than how we wish they did.

That is exactly what Vanessa Haydock and John Pemberton explored in Episode 29 of the GNL Podcast – and the five principles they discussed are as relevant now as they were when the episode aired.

Remove first, then build

There is an old idea – sometimes called via negativa – that improvement often comes from taking things away rather than adding them. Remove the friction. Eliminate the unnecessary steps. Strip out the noise. What remains is cleaner, lighter, and easier to sustain.

This applies to diabetes management as much as anything else. Instead of adding another app, another tracker, another thing to remember – ask: what can I remove that is making this harder than it needs to be?

Can you simplify your morning routine so the healthy choice is the default?
Can you batch your diabetes admin (sensor changes, prescription orders, clinic prep) into one slot instead of scattering it through the week?
Can you stop doing the thing that generates stress but adds no value?

When you reduce the load, you free up capacity – mental and practical – for the things that actually matter. That is what Vanessa has done with her own business: by streamlining her administration processes, she has freed up time and energy to do more of what she is best at – coaching people through sustainable change.

The five principles

These five principles came from a conversation between John and Vanessa on the GNL Podcast – grounded in applied behaviour analysis, coaching experience, and the reality of living with type 1 diabetes every day.

1. Design beats discipline

Willpower is finite. Type 1 diabetes burns through it faster than most conditions because the cognitive load is relentless – every meal, every correction, every alert. The fix is not “try harder”. It is reducing the number of fresh decisions you need to make each day.

Turn repeated choices into default rules – simple heuristics you already trust
Make goals concrete and realistic: think next-step (30% to 40% time in range) rather than leaps that trigger avoidance
Build the system once, then let it run – rather than relying on motivation every morning

2. Cues beat grit

Humans take the path of least resistance. If the environment does not prompt the behaviour, you are relying on memory under fatigue – which is a practical joke on yourself.

Place the thing you forget next to the thing you always do
Piggyback new behaviours onto existing routines (shower, kettle, brushing teeth)
Make the healthy option visible and the unhelpful option invisible

3. Reduce threat before effort

If the goal feels too big, too shaming, or too emotionally loaded, avoidance behaviours rise. Diabetes is uniquely cruel here – you can do everything right and still get a glucose reading that looks like failure.

Lower the demand level until you can engage without dread – small wins first, then scale
Reframe CGM data from judgement to information: not a moral grade, just feedback
Use learning language: “What happened? What is the likely driver? What is one tweak for next time?”

4. Hawk or Owl, Carrot or Stick

Accountability is not one-size-fits-all. Some people thrive with frequent, direct check-ins. Others do better with spaced reflection and gentle prompts. Same with feedback – some want straight truth, others need encouragement first or they shut down.

Choose the support style that fits you – not the one you think you should need
Make it explicit with your coach, partner, or friend: how often, how direct, and what actually helps?

5. Community support, not shame

Diabetes is isolating, and isolation increases burnout and avoidance. But community can heal or harm depending on whether it is psychologically safe and reality-based.

Small, trusted groups tend to outperform large spaces where nobody has real accountability
Share the difficult days as well as the good ones – it normalises reality and reduces shame
The goal is support and learning, not comparison and perfection

Your five-step exploration

If April is your fresh start, try this framework. Pick one behaviour. Just one. Then walk it through the five steps:

Design: What is one behaviour you want to change? Write it down in one sentence.
Reduce threat: What is the smallest version of that change you could try for seven days without dread?
Cues: What existing routine will you piggyback onto – and what physical cue will you place where you cannot miss it?
Accountability: Do you need a hawk or an owl? Carrot or stick? Be honest about what actually works for you.
Community: Who is one person or small group you can be honest with this week without shame?

That is it. One behaviour, five steps, seven days. See what happens. Then decide whether to keep it, adjust it, or try the next one.
