After I came across Chris Kresser's article (here), I bought a glucometer and strips and checked out my BG according to his protocol. The first two days, everything was gravy. Fasting BG is around 79, and the highest I saw it hit was 116 1 hr after a meal of braised lamb and leftover rice with a snack of watermelon. Pulled pork with sweet potatoes and...ahem...a couple of craft beers? Same deal. Then it was back to baseline within the proper window.
I have been playing around with it for awhile, and then today ended up eating a hideous, regretful Waffle House (oh God, I know) meal - "syrup" (because it's HFCS...not maple), waffle, chocolate chips, hash browns, bacon, raisin bread...I don't know why I bothered to order unsweetened iced tea. Yea, and so I prostrate myself on the altar of good health, may I be forgiven!
I thought - well, since I haven't done Chris' third day test, might as well check it after this disaster. 1 hr postprand? In the 170s. Two hours later, and I'm still at 166. I have checked it several different times to see if I was making an error somehow.
I thought, well, this happens to people who eat low-carb diets, right? Physiological insulin resistance? But I don't know that I'm a low-carber. We eat white rice, sweet potatoes, white potatoes, root veg, etc. with pretty much every dinner. I am a fruit-devouring monster, so a day with a handful of berries, cherries, a plum, and a bowl of melon isn't uncommon when it's in-season. We make homemade mead and hard cider, and occasionally crack a gluten-free beer, so there's that, too.
I am just trying to figure out why my blood glucose was so high. Is this low enough carb intake to produce physiological insulin resistance? Was it because it was a meal that was just insanely carby-sugary-unnatural?
Here is what I think my carb intake would be like on my highest days (such as the days I mentioned above where BG was normal), excluding incidental carbs such as those from green veg:
1 c. white rice - 45 g
1 plum - 8 g
1 c. melon - 16 g
8 cherries - 8 g
1/4 c. blackberries - ~4 g
The sweetest homebrewed hard cider we've made (estimated) - 20 g
=101 g...my intake is probably around 1800-2100 kcals/day, so that's 19-22% of total energy. Fat probably rolls in close to 60%, which leaves 20% for protein.
What say you? Was it because I probably nommed the same amount of carbs in one sitting as I usually eat during the entire day? Should I be worried? Suggested further n=1 experiments (no more junk food; I felt like a beached whale after that meal!)?
