My decreasing "Dawn Phenomenon". YAY!

(IDM Educator) #1

This morning’s blood glucose and Ketone readings. Why is this especially significant for me? Because I still have a blood glucose rise due to “Dawn Effect” or Dawn Phenomenon. As the years go by that I am on the ketogenic diet and fasting, my dawn effect gets lower and lower. 90 is excellent and normal for a morning blood glucose reading.

That is something I’ve definitely noticed after several months of intermittent fasting: much lower “Dawn phenomenon” readings. Especially if I fasted all day the day before.

Very awesome. Congrats!!!


Thanks for sharing this. For the past week I have been experimenting with my food. Fasting until lunchtime then breaking with 4 tablespoons of chia in 1 cup of Almond milk. Evening meal 6 ounces of green veggies spinach/broccoli and 4 ounces of fatty meat. For the past 5 days fasting and after eating I have maintained 75, with just one day being 68

Thanks for the link to Dr. Fung’s post @Brenda. It gives me hope. My morning BG readings are still between 120 and 130 and his explanation of the fatty liver issue explains why they don’t go down as fast as I would like them to. I guess I need to keep calm and fast on… :wink:

How high had it been and was the trend slowly down? Did it take many years to even begin to be lower? Also, are you exercising prior to the reading?

I would like to know about other’s success and speed of lowering their dawn phenomenon as well. I seem to keep yo yo-ing with my diet. I have some food addiction issues that I deal with in addition to insulin issues. If I partake of non-keto foods, my dawn phenomenon issues return to what they were (120-130) or worse. I have only been IF for the last 4 months or so and I really only see any change in my morning levels after my few extended fasts. I am currently starting a 3 day fast. My BG this morning was 155. We shall see how things progress.


I’m interested to check if my morning coffee is causing an insulin spike. My question is, I do experience the dawn effect - at 5:45 am I was 95 - if it goes down after coffee is that an insulin response or just a simple lowering of the dawn effect?? Maybe I need to test fasted to see how fast it goes down on its own??
