I use a pump and a CGM, which equips me pretty well for troubleshooting my basal rates, but now I’m wondering if I’ve been addressing the problems in a way that makes them worse.
My old plan of attack was: I would notice, over the course of a week or two, that my blood sugar was rising out of range during a certain time of day; 6am-11am, for instance. So, I would fast during that part of the day for a week while I made small adjustments to my pump’s basal rate settings. Lately, this hasn’t been working quite as well for me.
Now, I wonder if the fasting itself was causing my blood sugar to rise, compounding the dawn phenomenon.
There’s a lot of semi-scientific stuff on the internet that talks about what your body does when you skip breakfast. The gist of it seems to be that your metabolism goes into a kind of famine mode; triggers the release of certain hormones (cortisol, and insulin if you’ve got it), and prepares you to store fat.
My theory is that skipping breakfast also causes your body to start dumping glucose into your system.
So far, my experience has sort of borne out the above hypothesis. I don’t even have to consume carbs at breakfast - a simple meal of scrambled egg whites with salt and pepper (and nothing else) eaten within 20 minutes of waking seems to keep the dawn phenomenon at bay.
Of course, I’m only experimenting on myself, which doesn’t exactly hit the standards of scientific rigor. I’d really like to know if others have had similar experiences.
