Message: <blockquote data-quote="DiabeticGeek" data-source="post: 15095" data-attributes="member: 7961"><p>It is not a question of getting a single "true" reading.  BG is constantly changing over time, and the important thing is the patterns of that change.  After a meal, BG will rise rapidly and then fall back to where you started.  To some extent it matters how far it rises, but it is much more important how quickly it drops back.  Typically, 1 hour after a meal the BG will be close to its peak and 2 hours after a meal it will be back somewhere close to where it started.  However, the types of food, combinations of food and other factors such as exercise and medication can make a big difference.  With some meals it can be back down in barely over an hour, others can take four or five hours.  If you really want to see what is going on, then you need to take a series of measurements and plot the changes on a graph (the area underneath the curve on the graph is the best measure of the impact that a meal has had).  However,  you get through a lot of strips like that, and although that sort of experiment might be useful for fine tuning a diet, it isn't something that you should be doing right now.  If you are doing a single measurement after a meal then 2 hours is probably the best time to do it - that will typically give you a rough idea of how large a glucose hit you have taken from the meal.</p></blockquote><p></p>
