| this thread is already raising some interesting points.
i agree that the more carbs introduced into the body will produce a raised blood glucose level. this we know. as an insulin user who doesnt produce any insulin myself, if i were to eat a slice of death by chocolate cake and spread that over several hours, all that would happen is a continuosly raised blood glucose level that would be difficult to manage with an injection (10 grams here 1 unit, another 10 grams there, another 1 unit). as a pre-diabetic i would suggest that you may be just stressing an already tired organ by sustaining long inducement of carbs to the body.
my own notes show that if i eat 100g+ carbs in one sitting i will more than likely have to correct for a higher reading at 3 hours after taking a shot to cover it. however if i only eat say 50g (or less) carbs i will see a much steadier post prandial figure. |
