@Janet3 Welcome to the forum and congrats on heading off in this healthier direction for yourself.
I’m not seeing a glaring disconnect between 130 and 131… the accuracy of the typical glucose meter is fairly wide. And averages of any sort can hide information as much as reveal it.
Keep taking good care of yourself as you now are and the serum glucose (and, more importantly, your underlying insulin cycles) will serve you very well in the long run.
Daily data gathering is important for some (it was a big attraction for me, I admit!), but eventually your body responds to good health and eating habits - and the data will confess. Keep up the great start
