My Tracking Notes: Why a Bad Week at the Office Spiked My Glucose Higher Than a Slice of Birthday Cake

Late one evening in the office parking lot, I sat in my truck and stared at a glucose reading that looked like I’d just polished off a box of glazed donuts. The number was 135. Now, for some people, that’s just a Tuesday, but I hadn’t eaten since breakfast. The only thing I’d consumed was four hours of back-to-back crisis calls with a difficult vendor who was threatening to blow a hole in my Q3 logistics. I felt that familiar hot prickle of heat rising up my neck as I looked at the meter, the same way I feel when a client disputes a perfectly valid invoice. It didn't make sense; my 'inventory' was low, but my 'output' was through the roof.

I’ve been at this for about 18 months now—the tracking, the spreadsheets, the kitchen counter that looks like a health food store exploded on it. When my doctor told me my A1C had hit the prediabetes threshold of 5.7%, I treated it like a failing department in my business. I started measuring everything. I learned that the A1C test reflects your average blood sugar over the last two to three months by looking at your hemoglobin, and I was determined to keep that number far away from the 6.5% line that marks the start of the diabetes category. But that night in the parking lot, I realized I was missing a massive variable in my calculations.

The Birthday Cake Benchmark

Back in early spring, I did what any methodical person with a glucose meter does: I tested the 'cake variable.' It was a family birthday, and my wife had made her famous pound cake. I ate a slice, waited, and checked. I saw a spike, sure, but it was predictable. It went up, my body handled it, and it came back down within two hours. It was a straightforward transaction. I understood the ROI on cake—you pay the sugar tax, and you move on.

But this 'stress spike' I caught last month was a completely different animal. It wasn't just a quick peak; it was a stubborn, high plateau. The sharp, sterile smell of the alcohol prep pad hitting the humid Georgia air as I sat at my desk for a follow-up test an hour later reminded me that something was wrong. My glucose was still hovering in the 130s despite me not having a single carb. It was as if my body was manufacturing its own sugar supply behind my back, ignoring the usual rules of supply and demand.

When the Office Becomes a Sugar Factory

I’m not a doctor, and I have zero medical training, so I did what I always do when my business numbers don't add up: I went down the rabbit hole. I discovered that when we’re under fire, the body releases cortisol. This is the 'fight or flight' hormone, and its entire job is to make sure you have enough energy to either fight a bear or run away from one. It does this through a process called gluconeogenesis—which is just a fancy way of saying your liver starts dumping sugar into your blood to fuel your muscles.

The problem is, when I’m sitting at my desk arguing with a vendor, I’m not running anywhere. I’m just sitting there while my liver floods my system with 'free' glucose that I have no way to burn off. This was the 'aha' moment for me. I’d spent months meticulously reading nutrition labels and testing every dropper and capsule I could find, treating my body like a chemistry set, but I was ignoring the pressure cooker it was sitting in. No amount of cinnamon or chromium can outrun a constant state of high-pressure 'fight or flight.' It’s like trying to fix a leak in the warehouse while the fire department is actively pumping more water into the building.

Auditing My Calendar Against My Meter

After about two weeks of tracking my glucose specifically against my stress levels, the patterns were undeniable. I started cross-referencing my glucose logs with my Google Calendar. My 'calm' weekends, where I was just working in the yard or watching a game, showed beautiful numbers. My fasting glucose would stay right near that normal fasting glucose upper limit of 99 mg/dL. But the minute my inbox filled up on Monday morning, the baseline shifted upward, regardless of what I ate for breakfast.

I remember one specific Tuesday last month. It was a day of 'small fires'—nothing catastrophic, just constant interruptions. I was taking my usual supplements and sticking to my high-fiber snacks, but my numbers stayed 15 to 20 points higher than they were the previous Saturday. I realized that my stress was wrecking my blood sugar more than a slice of cake ever could because the stress was chronic. You only eat cake once in a while, but you live in your job 50 hours a week. I’d written about this kind of frustration before in my notes Beyond the 6.1 Wake-Up Call: My Tracking Notes from a Year of Testing Labels and Droppers, but the stress connection really cemented it for me.

The Cost of Doing Business

In business, you have fixed costs and variable costs. I’ve realized that my diet is a variable cost—I can control it. But my stress has become a fixed cost that I need to aggressively manage if I want to see a real ROI on my health. I’m the guy who brings his own grilled chicken to a neighborhood barbecue now, which is a bit of a running joke with my friends, but it doesn't matter if I bring my own food if I’m still checking my work emails under the table and getting my cortisol up.

I’ve tested a lot of different approaches to keep things stable. I even did a Sugar Defender vs Apple Cider Vinegar: My Experience With Both comparison to see which one helped more with those stubborn post-work spikes. While some things certainly helped dampen the blow, they didn't address the root cause of the liver dumping sugar into my system because I was stressed out. You have to talk to your own doctor about these things, obviously, but for me, the data showed that the mental side of the ledger was just as important as the physical one.

Managing the Internal Overhead

Since that realization mid-November, I’ve changed my routine. I didn't stop the supplements—my kitchen counter still looks like a pharmacy—but I started 'prescribing' myself five minutes of deep breathing before I even touch my glucose meter. I found that if I check my levels while I’m still heated from a phone call, the number is a lie—or rather, it’s a reflection of my mood, not my menu. When I take a few minutes to decompress, the numbers finally start to stabilize.

It’s a lot like managing a small business. You can’t just look at the sales; you have to look at the overhead. Stress is the ultimate overhead. It’s the hidden expense that drains your resources and makes everything else work twice as hard for half the result. I’m still tracking everything in my spreadsheet, much to my wife’s amusement, but I’ve added a new column: 'Stress Level.' It’s the only way to make the rest of the numbers make sense. If you're struggling with numbers that don't match your diet, I'd suggest doing a six-month deep dive into your own tracking to see if your office is doing more damage than your kitchen.
