Hi,
Two points if I may:
1. Don't feel bad about the 4.7 to 8.2 change from a 4.0 to 7.3 ! Your pre Breakfast was up by 0.7 , which is actually good, since 4.0 may suggest you may be close to Hypo overnight, so having your post-breakfast go up by 0.9 means it is only up by 0.2 from where you would expect it to be. And it is still below 8.5.
However like bulbbiker said,if you want your post-breakfast reading to be lower, then I suggest you just stick to proteins and fats for breakfast - so meat or fish (fatty is better), eggs ( the best balance food you can find), cheese, yoghurt, cream , leafy green veg. For example Spinach Omlette, Cheese Omlette, Bacon and Eggs, Boiled Eggs, a few strawberries or raspberries with double cream (if the meter says they are OK).
I don't mind having same breakfast every day (unless I am doing an Intermittent Fast - in which case no breakfast). So my breakfast is 2 hard boiled eggs with a cup of green tea (no sugar or milk). I find that doesn't raise my Blood Glucose at all at the 2hr mark.
2. How are your lunchtime and dinner time readings? I would be concerned about any readings over 8.5 at the 2hrs post-prandial measurement ( you first reported you were well over that after dinner). If so check again at the 3hr mark and also look carefully for hidden carbs in that meal.
Feel good about yourself - you can and you will control this thing now you have some basic knowledge. You now know more about it than the average Healthcare Professional!
