I usually have a 12 hour or so fast since I eat around 5:00 PM and get up around 4:30 AM and eat within an hour or so. As my morning numbers have come down, I have noticed something a little odd with my post breakfast numbers. I usually get a post breakfast drop in BG of 10 or so points. My typical breakfast has 30-40 grams of carbs and my 1 hour test is usually in the 70s to low 80s. At two hours I’m usually back to 80s to low 90s.
What I think is going on is that by pre breakfast numbers show me how well I’m dealing with my liver’s glucose dump and my post breakfast numbers are showing the liver turning off and how well I’m dealing with the carbs in my breakfast.
What I’m curious about is if I’m doing myself any harm by fasting so long since I have higher numbers from the fast than I do from breakfast. Since those numbers are in a good normal range, I’m thinking it should not be an issue, but I don’t want to abuse my pancreas any more than I already have.
