Four Day Fast – Day 1

Long-time readers will know that I’ve been paleo for seven years which allowed me to give up insulin. I also dropped a bunch of fat. Things have been sticky for the last few years in that my haemoglobin A1c levels have ranged from 6.4% to 7.6%. Good, but not great. One of the reasons for creating this blog was to help push myself to achieve that golden sub-5.7% HbA1c.

Increasing the frequency and duration of my fasts is one way I’m trying to achieve this goal. Today was day one of my four-day, water and coffee only fast. How did it go?

The Good

Well, I feel good. My energy levels are the same as usual; after work, I went for a six kilometre walk and lifted some heavy things. As of two hours ago, my blood pressure is a excellent 123/77 at 63 beats per minute.

The Bad

The first day of a fast is always the hardest for me. Today was no different. I’m hungry, and the water-only regimen makes it harder than my typical “fat fasts” which consist of double cream in my coffees and the odd tablespoon of coconut oil. There’s nothing to satiate my appetite other than water, which only works for an hour or two.

The Ugly

I woke up this morning with a not great 8.5 mmol/L (153mg/dl). I still think this is a hangover from too much “glass here-glass there” wine drinking, and it will take a while for my body to adapt. What’s worse though is that I checked my blood an hour ago, and it was higher than this morning: 9.0 mmol/L.

What the heck’s going on here you might ask? I’ve eaten nothing all day, so one would think my blood sugar should have come down especially after an hour and a half of exercise. It could be a few things: the caffeine in the coffee, the exercise spiking my glucose again or my lazy pancreas.

I’m not ruling out the caffeine, which is going to be another experiment in July, where I will wean myself off this delicious drug. We’ll see what that does to my blood glucose. Nevertheless, I think this could be due to my pancreas not releasing much if any insulin because I haven’t eaten anything today. I recall reading somewhere that the pancreas, when damaged like mine, is a bit dopey and does not release insulin without food coming into the body. The consensus view is that the liver is releasing glucose into my body to compensate for the lack of food. That’s possible too.

Conclusions

So not the best of starts, but not terrible either. I was hoping for my blood to be a bit lower after my workout. Still, my blood tends to go down quite a bit between 6:00pm and 10:00pm for some reason.

I’m guessing my blood will be significantly lower tomorrow morning if the past is anything to go on. “Day twos” are usually very good energy wise as well. We’ll see.
