Yesterday's Efforts vs. Today's Goals Since I worked hard on eating yesterday, I thought I should work hard on exercising today. I focused on a lower-body routine with squats and Romanian deadlifts. After the workout, I could feel how much my muscles were stimulated—my entire body felt sore, so I treated myself to a session with the massage gun for the first time in a while. Post-Workout Incident As I was taking off my workout clothes, I heard a little "pop!" sound, and something dropped to the floor. Upon closer inspection, I realized it was my continuous glucose monitor (CGM) that had been attached to my left forearm. Yes, it had been dangling since yesterday afternoon, and it finally gave way. Still, it hung on well until the morning of day 15, so I think it did its job. Actually, my interest in tracking blood sugar has decreased, and there were a few inconveniences as well, so I was planning to remove the sensor this afternoon instead of tomorrow when it expires. But maybe it worked out for the better. No Glucose Tracking Today Since the CGM is off, there's no glucose data for today. I had an iced Americano in the morning before working out, and afterward, I had a protein shake. For lunch, I ate bulgogi, had a Zero Coke brownie as a snack, and for dinner, I ate 150g of rice with homemade chashu. By my standards, this isn't a meal that would cause a big blood sugar spike. I usually maintain this kind of diet. Since it feels like a shame to end here, let's review some past data. Glucose Tracking Recap Looking at the average blood sugar over the entire period, my fasting glucose stayed in the 80-90 range, and even after meals, my blood sugar didn't rise significantly, so the average came to 97. I'd say that's a pretty healthy number. Excluding days like yesterday when I had cheat meals, there wasn’t much variation in my blood sugar levels. Nothing particularly interesting to note. Personal Conclusions from This Experiment Here are my personal takeaways: I am sensitive to white rice. I can handle about 3/4 of a bowl per meal. My blood sugar doesn't spike much even when I consume liquid carbs after strength training.

Today, I decided to test all the foods I don’t usually eat but occasionally indulge in, all in one day. I faced an unexpected challenge as soon as I woke up. Normally, my blood sugar stays around 80–100 while I sleep, but for some reason, my sensor started warning that my blood sugar was low. Since my blood sugar couldn’t have dropped that much, please take today’s cheat day and blood sugar log with a grain of salt. I ate a vague portion of rice cakes. Someone ate more of the rice cakes I had saved for today, so I scraped together the leftovers and ended up with a half-hearted portion. Even though the sensor has been tending to report my blood sugar on the low side, it’s good at catching the peaks. I saw my blood sugar hit 200 for the first time—it was quite surprising. Maybe I ate too much? Luckily, I didn’t feel too bad or uncomfortable. My blood sugar was all over the place, rising and dropping like crazy. When I did a finger prick test to check, the discrepancy wasn’t too bad. Especially for high readings, the sensor seemed reliable. For a snack, I wanted to buy a baguette and spread some butter on it, but unfortunately, it wasn’t available yet. So I bought a coffee bun and a cheese bagel instead. Since I don’t react much to flour, my blood sugar didn’t spike much. For lunch, I went out and bought sushi. I ate 12 pieces of sushi, a roll, and some udon, then walked about 1,500 steps back home. On the way back, my blood sugar dipped once but peaked again at just 105—not as big a deal as I thought.
