    Hi folks,
    I’ve read that the post prandial test should be done 2 hours after your first bite of food…I’m a bit confused as to how accurate a reading one can get because, for me, I can finish eating a meal an hour+ after I start it, and will normally end with some fruit. How can I make sure I’m getting an accurate reading that properly reflects my levels?

    The answer is you don't.
    The 2 hour rule comes from the75g OGTT which is pure glucose consumed in seconds with no fat/protein content.

    Real world eating is nothing like that, a social occasion could mean grazing over 3 courses across the course of an evening washed down with various drinks. 2 Hour after your first bite could be 1 hour after the Tiramisu.

    So keep the 2 hour adage to small meals with a defined amount of carbs.

    Agree that meals often last longer than two hours...we often have meals that start about 7pm and finish around midnight. I got through this problem in the early days by testing before eating as usual, and then testing at 30 mins, one hour, two hours etc, during the meal to get a clearer picture of what was going on with various foods as well as immediately afterwards. It does use the strips up, but I only did it a few times to establish the pattern. For me, adding alcohol means that all readings are lowered anyway and I can finish one of these extended meals with a lower BG than I had when starting. I do see a slightly elevated level for much longer (6-8 hours), but no spikes. You need to find out what your own pattern is.
