You’ve been making better choices. Swapping the sweets. Watching your portions. Walking after dinner. Maybe you’ve even lost a few pounds. And yet—your A1C is still creeping up. Why?

It’s frustrating. It’s discouraging. And it’s downright confusing. And many of the people who seek help for a Type 2 Diabetes diagnosis are doing “everything right,” but their blood sugar still isn’t cooperating. And they’re left wondering what they’re doing wrong… or if their body is simply broken.

But here’s what you need to know: You’re not broken. You’re not failing. You’re just missing a few critical pieces of the puzzle.

What A1C Doesn’t Tell You (But You Deserve to Know)

Your A1C is a snapshot of your average blood sugar over the past 2–3 months. And while that number is useful, it’s also limited.

It doesn’t tell you when your blood sugar is spiking (like after meals or at night). It doesn’t tell you why your cells aren’t responding to insulin the way they should. And it certainly doesn’t tell you whether your current approach is healing the root cause—or just covering up symptoms.

If you’re relying solely on medications or generic diet advice, your A1C may stay stuck—or even climb—because the underlying dysfunction hasn’t been fixed. Let’s take a closer look at why that happens.

5 Reasons Your A1C May Be Rising—And What to Do Instead

1. You’re Cutting Carbs… But Not Balancing Your Meals

Many people slash carbs and expect their blood sugar to magically improve. But without the right balance of protein, fiber, and healthy fats, your meals can still trigger spikes—or leave you crashing a few hours later.

Here’s what to do instead:
Build each meal around a clean protein source (like chicken, eggs, or tofu), fiber-rich vegetables, and a portion of healthy fats (like avocado, nuts, or olive oil). This combination slows digestion, improves insulin sensitivity, and gives you more stable energy throughout the day.

2. You’re Exercising… But Spiking Cortisol

Exercise is one of the best tools for blood sugar control—when done correctly. But if you’re pushing yourself too hard with long cardio sessions, your body may respond by flooding your system with cortisol (the stress hormone), which can actually raise your blood sugar.

Here’s what to do instead:
Swap high-intensity cardio for gentle movement like walking, strength training, or yoga. Even just 10 minutes of walking after meals can help lower blood sugar naturally—without overwhelming your nervous system.

3. You’re Eating “Healthy” Packaged Foods

Granola bars, protein shakes, “low sugar” snacks—many of these are marketed as diabetes-friendly but are loaded with artificial sweeteners, hidden sugars, and inflammatory oils.

Here’s what to do instead:
Stick to whole, unprocessed foods as much as possible. Think: grilled proteins, roasted veggies, whole grains, and healthy fats. If you can’t pronounce an ingredient, your body probably doesn’t know what to do with it either.

4. You’re Not Sleeping Well—And Don’t Realize How Much It’s Impacting You

Sleep is the foundation of blood sugar control. Just one poor night can make your body more insulin resistant the next day—meaning your cells stop responding to insulin properly, even if your diet is on point.

Here’s what to do instead:
Prioritize 7–8 hours of consistent, quality sleep. Turn off screens an hour before bed, keep your bedroom cool and dark, and consider a magnesium supplement if you’re struggling to wind down.

5. You Haven’t Addressed the Root: Cellular Insulin Resistance

This is the one that trips most people up. You can eat better. You can walk daily. You can even take your medication exactly as prescribed. But if your cells aren’t responding to insulin, none of it will stick.

Insulin resistance at the cellular level is what drives Type 2 Diabetes. And unless that improves, your A1C won’t either.

Here’s What to do instead:
Start working with someone who understands how to repair insulin sensitivity from the inside out. This includes balancing stress hormones, improving mitochondrial health, and supporting the body with the right nutrients—not just managing numbers.

You’re Closer Than You Think To Healthy A1C Levels

If your A1C is rising and you’re feeling defeated—don’t give up. This isn’t about willpower. It’s about strategy. And when you have the right one in place, everything starts to change.

You’ll wake up with more energy. You’ll stop relying on willpower alone to make good food choices. And you’ll finally start to see the numbers reflect the effort you’ve been putting in.

It’s not too late. And it doesn’t have to be as complicated as it seems. Start with just one change today—and keep moving forward. Your future self will thank you.
