And the spike is sooner than 2 hours... I thought the point of 2 hour post meal readings was to see how quickly your insulin brings it back down. Hence the oral glucose tolerance test with 75g of glucose and nothing to slow absorption
Fat can have a significant impact on the spike - how high it will go and how long it will last, so a very fatty meal might only bring a rise of X, but that rise could last much longer than "usual", thereby the net period of raised blood glucose is greater.
The OGTT is a blunt instrument in terms of performance, and quite unpleasant to undergo. I passed my home OGTT a few years ago, testing every 15 minutes for the duration of the test. Interesting, but not something I'm in a massive hurry to repeat.
