This comes from a question on another forum where we have one of those exercise fanatics who actually does seem able to control on a high carb diet and masses of exercise (there are a few who are genuine but they are generally outnumbered by those folks for whom carb control is #1 factor)
Now I find that if I wait until my BG has peaked, which is generally about an hour after eating, then go for a walk, everything evens out nicely.
If I walk immediately after the meal I can produce some spectacular drops. Now this can be a good way of burning off excess carbs when I've eaten out but can be less good when done after a minimal-spike meal when it can lead to hypo or near-hypo numbers (I am usually functional down to around 3.5) and can drive the system unstable for a while as the BG jumps up and down between hypo and liver dump and back.
My first thought was that it's a function of the funky GLUT-4 receptors: in the presence of the high postmeal levels of insulin (well as high as I can manage) they stash the glucose faster than it goes into the blood.
My second thought was that maybe the exercise sends the blood into the limbs and muscles and leaves the food in the gut untended and therefore not actually being converted to glucose at the usual rate.
Anyone got any other ideas or research to back them up?
