I have a question about "fat spikes". I've heard from so people that if you eat a fatty meal like pizza, that the spike happens a few hours later, so if you bolus up front with fast insulin (Humalog, Apidra) that BG will drop before the carbs kick in. My daughter doesn't eat regular pizza due to celiac, and generally doesn't eat fatty meals either (burgers, fries), but of course some meals are fatty and others are not, and we have never in 2 years observed this so-called "fat spike". No matter what she eats, the food always raises her BG faster than insulin, even faster than Aprida which we have been using since July. We've never seen any situation, including a desert of ice cream, or a gluten free pizza which still has lots of cheese, where a up-front bolus results in a drop before the rise. We've tried extended boluses just to experiment, and they always make matters worse - any kind of extended bolus results in a higher rise and longer recovery time, no matter what kind of food. Now, I am wondering if for some reason my daughter is simply not succeptible to this, or if the "fat spike" only happens with hugely fatty meals such as a eating an entire pizza or a 2-pound burger with fries? I am curious if anyone who uses a CGM has plots to show what a fat spike looks like for something like pizza, or showing how BG looks when eating pizza then using an extended bolus.
