I was hoping someone would have an actual graph showing a ramp. If it occurs in different people at any time between 3am and actually getting out of bed, possibly later, then the long standing threads comparing fbg might actually be comparing different timings of dawn phenomena.
I agree that if you are metabolically healthy, then it doesn't matter when you test, in fact if you know you are metabolically healthy then why bother testing. However, as this is a diabetes forum. most people will have some metabolic impairment. It is not a question of knowing when to test for the best result, but when to test to give a good representation of whether the impairment is getting better or worse.I think many of us miss the salient point of dawn phenomenon discussion as it pertains to dysglycemia. In metabolically healthy individuals, DP should hardly be measurable as elevated glucose at all, since the regulatory and counter-regulatory hormones will maintain homeostasis within a very narrow corridor either side of baseline.
Talk of dawn phenomenon and fasting glucose shouldn’t be viewed as a competition between individuals finding the best time of day to get the result they want. It should be viewed by individuals as a marker of their own metabolic derangement (or lack of). In other words, if you are metabolically healthy, it won’t really matter what time you test (to a degree). If it does, then you are not metabolically healthy. This is the whole point of fasting glucose being a good marker of metabolic health.
In my opinion.

What time do you get up and what time do you have breakfast?Although not a massive rise here is a screen dump from one of my Libre reports. It has settled more since low carbing. What I did find also was when I had to spend 10 days working in the USA it 'broke' a cycle of heavy dawn responses (time difference) So there is a way to mess with your body clock ;-)View attachment 35575
Thanks for that. I looks to me that you are getting a rise starting from the alarm clock ringing, so no pre-emptive rise while you are still asleep. As I can't do a finger prick test before I wake up, "feet on the floor" looks like the best bet for fbg. Later would show how well, or not, I cope with dawn phenomena.My alarm clock normally drags me out of slumber around 06:30hrs and I have a couple of cups of tea about half an hour later, but no breakfast.
