I ate a pizza today for lunch (it was only a medium pizza, 132 grams of carbs total).
For reference, I set the “high” number on the Dexcom to 120, just to give a good visual of it.
A good downward slope before I started, an aggressive bolus, and a little extra insulin pop an hour later, and I never got above 114 and didn’t need any sugar correction. (The low looks worse than it actually was. For me, Dex always lingers on the low number much longer than in reality.)
I think it’s just my Italian heritage that lets me eat pizza with no worries…
