No, I wouldn't test right after eating. The advice is normally to test at 1hr or 2hrs or you could follow this advice to test and find out when your peak level occurs:
Occasionally I do but it is part of an experiment with a new food and then I test every 15 mins for about 3 hours to profile what it does to me. Different foods have different digestion times and rarely are they in my blood stream straight after eating (haven't tried white bread since diagnoses or fruit juice - maybe that is the next experiment)
I can't see the benefit of testing right after eating as it can lead to a confusing reading, what portion, if any, of the food has started to increase BG levels ?
I agree mo and normally do 1 and 2 hours and occasionally when I can't quite understand link yesterday. 1 hour @ 7.7, did some exercise (30 mins) 4.4 @ 1.5 hours, 7.5 @ 2 hours!!, 4.8 @ 3 (and all I did was sit at the computer typing)
Talk about bouncing up and down
PS often test after exercise if my fingers and hands have gone numb/cold as this is my indicator for low levels
