You probably think you don’t eat too much sugar, and insulin resistance is something that happens to other people. You may be right, but before you skip ahead, let’s look at what the numbers actually tell us.
The Hidden Reality of Sugar Consumption
According to the Green Pool report, the average Australian consumes nearly 42 kilograms of sugar per year. That’s not just the obvious culprits like sweets and soft drinks. It’s hiding in bread, pasta, sauces, yogurts, and countless “healthy” processed foods lining supermarket shelves. Even those of us who think we’re eating well may be consuming far more than we realise.
Here’s the thing: this isn’t about judgment or shame. Our relationship with sugar is complex, woven through our earliest memories and deepest cultural practices.
How Insulin Actually Works: The Dance Analogy
Think of insulin as a compassionate escort service for your body. When you eat carbohydrates that break down into glucose (blood sugar), insulin acts as the chauffeur, safely transporting that sugar from your bloodstream into your cells, where it can be used for energy or stored for later.
Imagine it like a dance: the more glucose “dancers” flooding your bloodstream, the more insulin “partners” your pancreas needs to produce to escort them all safely off the dance floor. In a healthy system, this dance is balanced and elegant.
The Cultural Weight We Carry
Our Nana showed love with homemade biscuits. Our parents rewarded good behaviour with lollies. Sugar fills every Christmas stocking and Easter basket. It’s at every celebration, every comfort moment, every “you deserve a treat” occasion.
When something is this deeply embedded in how we express love, celebration, and comfort, of course, we tell ourselves: It can’t really be that bad, can it?
But here’s what we now understand: if there was a single substance proven to contribute to addiction, obesity, mood disorders, acne, cardiovascular disease, dementia, and numerous other severe conditions, would you knowingly choose it? When in your rational, clear-minded self, probably not.
Yet sugar’s grip is anything but rational. It’s emotional, neurological, and deeply habitual.
When the System Breaks Down: Understanding Insulin Resistance
Over time, with chronic exposure to high sugar and refined carbohydrates, your body’s beautiful glucose-insulin system becomes exhausted. Imagine being at a ball that never ends—eventually, even the most dedicated dancers grow tired.
This is insulin resistance: your cells stop responding effectively to insulin’s knock at the door. They’ve heard it too many times and seen too many glucose deliveries, so they start ignoring the signal. Your pancreas responds by producing even more insulin, desperately trying to get the message through.
The Blood Sugar Rollercoaster: What Changes When You’re Insulin Resistant
Once you’re insulin-resistant, your response to food—especially carbohydrates—fundamentally changes. Here’s what’s happening inside your body:
When you eat something sweet or starchy, your blood glucose spikes. Your pancreas floods your system with insulin, working heroically to restore balance. But because your cells are resistant, it takes far more insulin than it should.
This excess insulin eventually succeeds—sometimes too well. Your blood sugar can plummet below the healthy range, triggering a cascade of uncomfortable symptoms and intense cravings. You’re on a blood sugar rollercoaster, and your body is screaming for you to get off.
Why This Matters More Than You Think
Insulin resistance isn’t just about numbers on a test. It’s about how you feel every single day. It affects your energy, mood, ability to think clearly, weight, skin, fertility, and long-term health trajectory.
Left unchecked, insulin resistance is the pathway to type 2 diabetes, but it also contributes to:
- Heart disease and stroke
- Fatty liver disease
- Polycystic Ovary Syndrome (PCOS)
- Alzheimer’s disease (sometimes dubbed “type 3 diabetes”)
- Certain cancers
- Chronic inflammation throughout the body
Do These Symptoms Sound Familiar?
You might be insulin-resistant if you experience:
The Energy Crisis: Those dreaded 3-4 pm energy crashes where you’d do anything for a nap or a sugar hit. You wake up tired even after a whole night’s sleep. You need caffeine to function.
The Hunger That Won’t Quit: Intense, irresistible cravings and hunger pangs that would see you gnaw through anyone standing between you and your fridge. You’re never quite satisfied after meals. You think about food constantly.
The Mood Swings: You get shaky, irritable, or downright furious when you’re hungry (hello, “hangry”). Your mood lifts immediately after eating, but crashes again hours later. Brain fog makes it hard to concentrate.
Physical Signs: Stubborn weight around your middle that won’t budge despite your best efforts. Darkened skin patches (acanthosis nigricans) around your neck, armpits, or groin. Skin tags. Persistent acne.
Who’s Most at Risk?
You’re very likely insulin-resistant if you have:
- Type 2 diabetes or prediabetes
- Polycystic Ovary Syndrome (PCOS)
- Metabolic syndrome
- A family history of these conditions
- Excess weight, particularly around your abdomen
- A sedentary lifestyle
- A history of gestational diabetes
But here’s what many don’t realise: you can be insulin-resistant while appearing perfectly healthy. You can have a “normal” weight and still have this condition. It’s not always visible from the outside.
The Testing Problem: Why Standard Tests Miss the Mark
This is crucial: most standard glucose testing completely misses insulin resistance in its early and middle stages.
Your doctor likely orders a fasting glucose test or perhaps a glucose tolerance test. These might come back “normal,” and you’re told everything is fine. But here’s the problem: by the time your glucose levels are elevated, you’ve already been insulin-resistant for years, possibly decades.
What’s actually happening: Your glucose looks normal because your pancreas is producing massive amounts of insulin to keep it that way. It’s like judging whether a juggler is struggling by only watching the balls in the air—everything looks fine until the moment they all come crashing down.
What You Actually Need to Test
To accurately assess insulin resistance, you need tests that look at insulin levels, not just glucose:
- Fasting insulin test: Measures your insulin levels after an overnight fast
- HOMA-IR score: Calculated from your fasting glucose and fasting insulin
- Glucose-insulin tolerance test: Measures both glucose AND insulin at multiple time points
- HbA1c: Shows your average blood sugar over the past 2-3 months

Moving Forward with Self-Compassion
If you recognise yourself in these descriptions, please know this: insulin resistance is not a character flaw or personal failing. It’s a physiological adaptation to an environment our bodies weren’t designed for—one filled with processed foods, chronic stress, inadequate sleep, and constant demands on our time and energy.
The good news? Insulin resistance is often reversible, especially when caught early. Through strategic changes in nutrition, movement, sleep, stress management, and sometimes medication, you can restore your body’s sensitivity to insulin and reclaim your vitality.
This is about understanding your body with curiosity and kindness, not punishment. You deserve to feel energised, clear-headed, and comfortable in your body. And that starts with accurate information and appropriate testing.
