Readers will know that I went on a four-day, water/black coffee only, fast last week. My blood glucose levels came way down. On the morning of Day 4, my blood glucose was 4.1 mmol/L.
I’ve done similar fasts in the past, but I could not maintain ideal blood control due to bad habits: mainly red wine, too much protein, too much dark chocolate and too many nuts.
So where am I today one week later? Blood glucose is far better than in the past. My numbers, up until yesterday morning, were between 5.7 and 7.6. Unfortunately, after too many nuts and meat protein on Thursday night, I woke up with a reading of 8.6 mmol/L. Now historically, this is not that bad a reading for me. However, there is no way I’ll reach my 5.7 HbA1c this autumn if I tell myself “It’s not so bad, you’re sugar will go down during the day.” It will go down, but not enough.
So what to do?
Simple. I had a small breakfast on Friday and then went on a 24 hour fast. Result. I woke up this morning with a 6.2 mmol/L. This is my way forward I think. If my morning reading is above 7.6 then I have to go on at least a one-day fast to get close to optimal blood glucose.
We’ll see how this goes. It’s essentially intermittent fasting, but dictated by my blood-glucose readings.
