6.1 this morning. I did a lot of testing yesterday. Basically with a deliberately indulgent lunch including 85% cocoa solids chocolate and a nice lump of cheese plus peanuts on top of cold chicken and a salad (1100 calories and 19g carbs) I experienced a BG rise of almost 3 units. so a bit disappointing. In the morning for breakfast I had a low carb flax/linseed muffin made with egg and an additional egg; 450 calories and 5g carbs. I started off with a BG of 5.3 and 2 hours later it was 6.0. For supper I had salmon and a few prawns with vegetables and a cream sauce (730 calories and 10g carbs) and BG went from 5.3 to 6.3. It seems by BG stabilises at around 5.3 which is basically what I find it to be before meals.
Your blood glucose readings for breakfast and lunch are all great!
You've made some good observations about how your blood glucose levels seem to stabilise.
The rise at lunch may well be to do with too much protein? I recall briefly looking at our post on the what have you eaten thread. If I remember correctly you ate a large amount of protein as well as it being a high calorific lunch.
I think you know - but, I'll mention it any way - over 50% of protein can be converted to blood glucose. So that may have played a significant role in your 3+ mmol / L rise.
Still, you seem to be monitoring well and finding out what works for you - good stuff!
