Behind My Blood Sugar Log

About

I'm 51, small business owner in suburban Atlanta. My doctor flagged an A1C of 6.3 at a routine physical and told me to watch my sugar. I drove home, spent the next several hours reading everything I could find, and by end of that week I had a Contour Next One glucometer, three supplement bottles on the kitchen counter, and a dramatically different Google history. That was eighteen months ago.

I run a business that requires isolating variables — you change one thing, you track the outcome, you don't read causality from noise. Same framework here. Fasting glucose every morning at 6:47 AM before coffee — I take it before anything, because that's when you see the number without meal interference. I learned about the dawn phenomenon in month two when my readings were consistently higher than I expected until I figured out my liver was doing something unhelpful at 5 AM. Post-meal readings two hours after dinner. One supplement at a time, thirty days minimum, at the full label dose. Everything logged: date, time, reading, which supplement, day of cycle. The spreadsheet is something my accountant would recognize. My wife calls it "the obsession that got organized."

What I don't cover: meal plans, low-glycemic diets, carb counting, or cooking. My lane is the supplement side — what the glucometer showed during a 30-day run, recorded consistently. Three of those runs showed nothing moved. Those reviews are on the site too, because if I only published the wins, this would be a catalog, not a log.

Not a doctor, not a nutritionist. Talk to yours before any changes to how you're managing blood sugar — this is personal tracking data, not medical guidance.
