Insulin Resistance: What it is and Why It Matters
Feb 23, 2026
If you’ve been hearing the term insulin resistance tossed around but still feel fuzzy on what it actually means—pull up a chair. This first part of our series is all about breaking it down in plain English so you know exactly what’s going on in your body and why it matters for your health.
So, what is insulin?
Insulin is a hormone made by your pancreas. Its main job is to act like a key that unlocks your cells so glucose (a.k.a. sugar from the food you eat) can get inside and be used as energy.
When everything is working the way it should, insulin keeps your blood sugar stable and your energy steady.
What happens with insulin resistance?
When your body becomes resistant to insulin, that key doesn’t work as well anymore. It’s like trying to unlock your front door with a bent key—you jiggle, you push, you get frustrated. Eventually, your body has to make more and more insulin just to get glucose inside the cells.
The result? Glucose starts hanging out in your bloodstream instead of fueling your body, and high insulin levels cause a whole domino effect of problems.
Why it matters
Insulin resistance isn’t just a blood sugar issue—it impacts your whole body. Over time it can lead to:
-
Prediabetes and type 2 diabetes
-
Hormonal shifts (especially in women—think PCOS, irregular cycles, fertility struggles)
-
Weight gain, especially around the belly
-
Energy crashes and brain fog
-
Inflammation and higher risk for heart disease
And here’s the wild part: you can be dealing with insulin resistance for years before a lab ever shows it.
Red flags to watch for
These are some of the sneaky signs your body might be waving at you:
-
Afternoon carb or sugar cravings
-
Feeling “hangry” if you go too long without eating
-
Extreme fatigue after meals
-
Struggling to lose weight, even with healthy habits
-
Waistline creeping up, even if the scale doesn’t budge
The good news
Insulin resistance doesn’t mean you’re doomed. With the right tools—like balancing protein with carbs, moving your body, getting better sleep, and managing stress—you can help your body become more sensitive to insulin again.
That’s exactly what we’re covering in this podcast series: real talk about what insulin resistance is, how it shows up, and what you can actually do about it.
