This is because at that point any carbs eaten (at baseline) will have been digested and the body's insulin responses should have largely cleared them from the bloodstream - so you should be at or near where you started off.  The test is in practice a test of current insulin efficiency. In my experience - a test at +30 mins and you should see (maybe) the start of a rise in glucose (assuming some level of carb in the food eaten) - this can happen much more quickly where the carb is in an easily digestible form, such as hot sweetened milk.test at +1 hr could be around the glucose peak, depending: test at +1hr 30 mins should be seeing the start of glucose falling as the insulin starts to reduce glucose in the blood. All this is really clear on a CGM. It's also subject to variation depending on many things, but in general if we eat carbs there will be a natural rise and fall.</blockquote>
