Catching Insulin Resistance Early: Why We Can Do Better in New Zealand

Catching insulin resistance

If you’ve ever been told your blood sugar is “borderline” or had your HbA1c checked, you might think you’re managing your health well. But here’s the truth: insulin resistance often starts years before it shows up in tests like HbA1c, and by the time it’s diagnosed, your body is already under strain.

In New Zealand, the current system focuses on diagnosing prediabetes and diabetes mainly through blood tests like HbA1c or fasting glucose—often after symptoms or complications appear. This means many people miss the window where early intervention could prevent progression altogether.


At MyDispensary, we believe we can do better. We want to help people identify and reverse insulin resistance before it becomes a problem that requires medication. Here’s why.

How Is Insulin Resistance Usually Diagnosed in NZ?

Most New Zealanders find out they have insulin resistance or prediabetes during routine blood work or once symptoms develop. The key tests include:

  • HbA1c: Measures average blood sugar over 3 months
  • Fasting glucose: Measures blood sugar after an overnight fast
  • Oral glucose tolerance test (OGTT): Checks blood sugar response after a sugary drink

Why Waiting for HbA1c Is Waiting Too Long

HbA1c is a lagging indicator—it reflects blood sugar control over the previous 2–3 months. By the time HbA1c crosses the prediabetes threshold:

Insulin resistance has often been developing for years. Symptoms like fatigue, weight gain, and cravings may have worsened

Risk of progression to type 2 diabetes and related complications is high

What the Science Shows: Lifestyle Changes vs Medication

The landmark Diabetes Prevention Program (DPP) studied over 3,000 people with prediabetes and split them into groups:

  1. Lifestyle intervention focusing on healthier diet, weight loss, and exercise
  2. Metformin medication Placebo (no intervention)


After about three years, results showed:

Intervention Risk Reduction of Developing Diabetes
Lifestyle Changes 58% reduction
Metformin Metication Placebo 31% reduction


This means lifestyle changes reduced diabetes risk nearly twice as much as metformin medication.

The Mediterranean Diet: What It Is and Why It Works

One of the key lifestyle changes that showed strong benefits in preventing diabetes is adopting a Mediterranean-style diet. This eating pattern focuses on:

  • Colourful vegetables and fruits
  • Whole grains like oats, quinoa, and brown rice
  • Nuts, seeds, and legumes
  • Healthy fats such as olive oil and avocado
  • Moderate amounts of oily fish and poultry
  • Minimising processed foods, added sugars, and refined carbs
  • This diet reduces inflammation and improves insulin sensitivity,
  • supporting healthy weight management and heart health.

The MyDispensary Approach: Your Purple Prescription

Inspired by this evidence, we developed the Purple Prescription, a personalised, pharmacist-led plan to help reverse insulin resistance naturally and holistically.

Nutrition: Cut Sugar and Refined Carbs

We focus on reducing:

  • Added sugars
  • Refined carbohydrates like white bread, pastries, and sugary drinks
  • Highly processed foods with hidden sugars and additives


Instead, we encourage whole, minimally processed foods aligned with Mediterranean principles, emphasising stable blood sugar and inflammation reduction.

Supplements That Support Your Metabolism

Berberine: A natural compound with evidence showing it helps lower blood sugar and improve insulin sensitivity—acting similarly to metformin but often better tolerated.

Magnesium: Crucial for insulin signalling and commonly deficient in insulin resistance.

Fish Oil (Omega-3): Anti-inflammatory fats that support heart, brain, and metabolic health.

Probiotics: Support gut health, which plays an important role in metabolism and insulin sensitivity.

We select high-quality supplements to personalise your Purple Prescription.

  • Movement: Building Strength and Reducing Stress
  • Weight Training: Builds muscle, a major site of glucose uptake, improving blood sugar control.
  • Yoga and Flexibility Work: Lowers stress hormones and supports hormonal balance.
  • Walking After Meals: Helps reduce blood sugar spikes and supports digestion.
  • Mindfulness and Sleep
  • Chronic stress and poor sleep increase cortisol, which worsens insulin resistance.

Our protocol encourages:

  • Daily meditation or breathing exercises
  • Consistent sleep routines and good sleep hygiene
  • Relaxation techniques to improve sleep quality and balance hormones
