To be honest, it doesn't mean very much. You need to be organised.
Test immediately before you eat
Test again 2 hours after first bite
Look at the rise from before to after and keep this below 2mmol/l (preferably under 1.5 or less)
If the rise is too much, there were too many carbs in that meal.
If you also keep a food diary including portion sizes and write your levels down alongside, this will help enormously. You can see exactly what you ate and decide if there was anything there that your body reacted to, and then be able to change things, either by eliminating something or cutting the portion size.. It takes a while sometimes for patterns to emerge.
If you have enough test strips you can also test immediately you get up in the morning. This is your fasting blood glucose. It is often useful to also test before you go to bed.
Keeping records is a good plan.
