This is something that troubled me for a while.
I am not diagnosed with anything but I am in many of the risk categories and I developed new symptoms indicative of type 2 so this was a big motivation to follow the BSD as opposed to other diets. I bought a blood testing kit as DrMM suggests and gave it a go.
My first fasting reading was 5.6. On the American scale that would just put me into the pre-diabetic category. I took this as a sign I was hearing what my body was trying to tell me. I tested by blood before breakfast as part of my weekly weigh-in regime but just got frustrated and a little worried. The numbers were the same or even higher each week! One particularly stressful weigh-in morning I had a brainwave. I was getting myself wound up, pushing up my adrenaline and hence my blood sugars. I wasn’t testing myself until everyone was safely off to school or work. By that time I had worried about a dozen things, argued with the kids or maybe sat in a traffic jam or negotiated icy roads. Then I would worry about getting the test right as I struggled for a long time to get a big enough bead of blood to test. I would even wake earlier on weigh-in day and my first thought would be the blood test.
The solution for me was not to plan the test. Now I just grab the test kit from the side of my bed, every 5 days or so, when I first wake up. And of course I’ve had plenty of practice with the kit now so the process doesn’t bother me. I had my lowest ever reading this morning at 4.9.
I may not be right to interpret this the way I have – I have no expertise – but I think I’m on the right track now. I hope that helps you if you want to try again and understand your blood sugars.
