Continuous Blood Glucose Monitoring - On-bike nutrition and its impact on blood sugar

So yesterday I had lunch at a normal time, a protein shake around 4, and dinner at 5:55 pm. For dinner I had approx 1 cup white rice with beef and an onion gravy. My blood sugar peaked about 30 mins post meal at 37 mg/dl higher than when I ate.

I did the exact same today but had dinner at 5:30. I ate the exact same meal but substituted brown rice for white rice. 30 minutes post meal my blood sugar had risen 10 mg/dl, it did peak about 10 minutes later, but still only 15 mg/dl higher than my dinner blood sugar.

As was mentioned elsewhere in the thread, fats and proteins seem to blunt the effects of carbs in general. I would bet it’d be a bit more pronounced if having those carbs alone. I was fasted from carbs for 4-5 hrs before each of those meals.

Although the white rice was higher, only rising 35 (100>135) is totally reasonable. In the past I’ve had simple carbs (white breads/instant oats) that have skyrocketed me from like 100>185+. To me, that’d be a concern over a long period if someone was eating like that over every meal.

There’s other factors mentioned in this thread that aren’t really measurable, like other factors that may have contributed to my body releasing insulin to counteract on a certain pulsating type of cycle that could have impacted this comparison as well.

Either way, I feel pretty good about any meal that doesn’t spike my blood sugar past 140/150. I eat “pretty healthy” but still have white bread and ice cream occasionally. Being mindful of how much they spike my blood sugar at least keeps me in check. Leaving next week for a 2 week Colorado trip and you can bet I’ll be eating the sh** out of like a half dozen s’mores on multiple nights.. hopefully the Dexcom has expired by then :sweat_smile:
