Nutrition for
pre-diabetes &
type 2 diabetes
A diabetes diagnosis, or a pre-diabetes result that's caught you off guard, can feel overwhelming. It's also one of the clearest cases where what you eat makes a genuinely measurable difference.
What's possible when nutrition is taken seriously
These aren't cherry-picked outliers. They're what happens when someone with the right diagnosis commits to the process, works with a nutritionist who understands metabolic health, and keeps their GP involved throughout.
HbA1c in two and a half months, from the diabetic range to normal, with GP confirmation of remission.
Blood sugar brought back under control after a pre-diabetes diagnosis. “I feel so much better now.”
the board
Significant improvement in all blood markers. “Finally back to feeling like myself.”
These results involved real commitment from clients working alongside their GP. Individual outcomes vary, and nothing here is a guarantee. The research is clear that diet and lifestyle are among the most powerful tools available for metabolic health.
Wherever you are on the spectrum
Blood sugar issues exist on a continuum, and the earlier you address them the more options you have. I work with people at every point along it.
Proactive
Family history of type 2, or noticing energy crashes and cravings, and wanting to address metabolic health before any diagnosis.
HbA1c 41–49 mmol/mol
The most impactful time to act. Dietary change at this stage can prevent progression entirely.
Type 2 diabetes
Newly diagnosed or managing an existing diagnosis, with nutritional support alongside your GP or endocrinologist.
Working toward it
For some people with type 2, significant dietary change can lead to remission under medical supervision. The evidence for this has got a lot stronger.
Signs that blood sugar needs support
Many people live with blood sugar dysregulation for years before a formal diagnosis. These are the signals worth taking seriously, whether or not you've had a test.
Energy crashes after meals, especially lunch, that leave you foggy or sleepy
Strong sugar or carbohydrate cravings, especially in the afternoon
Irritability, anxiety or shakiness when meals are delayed
Weight gain around the abdomen that doesn't shift despite effort
Waking during the night, often around 2–3am
Elevated HbA1c, fasting glucose or insulin on blood tests
Increased thirst or frequent urination, both classic early warning signs
Brain fog or difficulty concentrating, particularly around meals
If several of these are familiar and you haven't had bloods done recently, that's the first thing to sort. Ask your GP for an HbA1c. Knowing the number changes what we can do with it.
Built around you
There's no single diabetes diet that works for everyone, and anyone telling you there is hasn't read the research carefully. What the evidence does support is a set of principles around food quality, meal composition and lifestyle that consistently improve blood sugar outcomes.
I apply those to your situation, meaning your food preferences, your schedule and what you're already doing well. I work alongside your GP or specialist, not around them.
Food quality and composition
What you eat, in what combination, and in what order all affect your glucose response. We build a practical pattern around the evidence, so lower glycaemic load, higher fibre and adequate protein, without eliminating everything you enjoy.
Meal timing and structure
Meal spacing, the timing of carbohydrates, and even the order you eat foods within a meal all meaningfully affect post-meal glucose. These are small, implementable changes with a measurable payoff.
Movement as medicine
Exercise improves insulin sensitivity more directly than almost any other intervention. Even ten to fifteen minutes of walking after a meal has a measurable effect on blood glucose.
Stress and sleep
Cortisol raises blood glucose directly and poor sleep impairs insulin sensitivity. Where these are significant in your life we address them, because no dietary plan fully compensates for chronic sleep deprivation.
Gut health
The gut microbiome plays a real role in glucose metabolism and insulin sensitivity. For some people, addressing gut health turns out to be a surprisingly effective lever on blood sugar.
Working with your medical team
Diabetes management involves your GP and possibly a specialist. I share notes where useful, help you ask the right questions, and keep the nutritional and medical sides of your care aligned.
The hour is the smallest part
Every consultation includes a full written clinical protocol, and that protocol takes three to four hours to build after you've logged off. The hour is where I gather the case. The work happens after it.
The consultation
Symptoms, health history, medications, bloods, and what you actually eat on a normal Tuesday, not an idealised version of it.
Research and case review
Your case worked through against the current evidence: what's likely driving it, what the research supports for your situation, and any interactions with your medications.
Your diabetes protocol
Diet, lifestyle and supplement recommendations with specific forms, doses and timing, plus the reasoning behind each, so you can question it rather than just follow it.
Yours to keep
A document you own and can come back to in six months, or hand to your GP. Nothing depends on how well you took notes.
Who I work with
This works best for people who are motivated to make genuine dietary and lifestyle changes, and who understand there's no quick fix but there is a real path forward. A good fit if you're:
- Recently diagnosed with type 2 diabetes and wanting evidence-based nutritional support alongside your GP's care
- Managing pre-diabetes and wanting to prevent it progressing, or reverse it
- Living with type 2 and feeling like your current approach isn't giving you the results or the energy you want
- Working toward remission under GP supervision and looking for the nutritional framework to make it possible
- Someone with a strong family history who wants to address metabolic health proactively
- Confused by conflicting diabetes advice and wanting a clear, science-backed approach you can sustain
Type 1 diabetes
This service is for pre-diabetes and type 2 diabetes. Type 1 is a different condition with different management, and it needs a specialist diabetes team and a dietitian working within it.
If you have type 1 and want general nutrition support alongside that team, get in touch and we'll talk about whether it makes sense.

“Luke is a wealth of knowledge if you are looking for nutrition advice. I was diagnosed with Type 2 diabetes, and after a month my doctor was absolutely amazed at my blood test results after following Luke's advice. Update: just wanted to let you know that your support was one of the main factors in sending my diabetes into remission! I went from 59 to 39 HbA1c in 2 and a half months.”Ash — Wellness Plan client
Diabetes nutrition questions
What does remission actually mean?
By international consensus, type 2 diabetes remission means maintaining an HbA1c below 48 mmol/mol (6.5%) for at least three months without glucose-lowering medication.
That's the gold standard goal. Not everyone achieves full remission, and it depends heavily on how long you've had the condition, but almost everyone can achieve better control and fewer complications.
Will you work with my GP or doctor?
Absolutely. I work as part of your team rather than in place of your doctor. As your diet improves your blood sugar will drop, which is good news, but it means your medication needs may change.
I can provide letters or reports to your GP so they can safely adjust or deprescribe as your health improves. Never stop taking medication without your doctor's supervision.
I'm already on insulin or metformin. Can you still help?
Yes, and nutrition matters more when you're on medication, not less. Medication manages the symptom, which is high blood sugar. Nutrition targets the underlying insulin resistance.
Many of my clients reduce their reliance on medication over time under their doctor's guidance as their metabolic health improves.
How long until I see results?
You'll likely notice a difference in energy and clarity within the first seven to ten days. HbA1c reflects roughly a three-month average, so we normally look for significant change on a blood test after about twelve weeks of consistent work.
Individual results vary, and nothing here is a guarantee of outcome.
I've been told not to eat fruit because of the sugar. Is that right?
It's a common myth. There's a large biological difference between refined sugar in a biscuit and the fructose in a whole piece of fruit that arrives packaged with fibre, water and antioxidants.
We focus on whole fruits such as berries and apples, and on how to pair them so they don't spike your blood sugar.
Will I be hungry? Is this a starvation diet?
No. The approach is about nutrient density rather than calorie restriction. When you're eating foods that keep blood sugar stable, cravings for sugar and snacks usually fade.
Most clients report feeling more satisfied after meals, not less, because they're finally being properly nourished.
Do I have to go plant-based?
No. I specialise in plant-based nutrition because the evidence for it in diabetes management is strong, but I'm not dogmatic and most of my clients aren't vegan.
We will focus on substantially increasing whole plant foods, especially vegetables, legumes and fibre, because those are the tools your body needs to restore insulin sensitivity. How far you take that is your call.
Does my health insurance cover this?
Often, yes. Because I'm a Registered Clinical Nutritionist rather than a health coach, many New Zealand insurers provide cover: Southern Cross on some plans, NIB under everyday cover, and UniMed (formerly Accuro) depending on policy.
Check your policy wording for “Registered Nutritionist”. I provide full invoices with my registration number after every session to make claiming straightforward.
