I'm about to do carb counting and i have had a dietition told me that fiber don't do anything to influance the glucose cost so by having 10 carbs and take away 5 fiber don't just give you 5 carbs. Lately i have lernt that the white bread is loaded with carbs so the cheese and bacon buns are full of it!!

I'd bet there's something to this. If a person always eats more-or-less the same foods every meal, this discrepancy will not be discovered. By changing carb types and quantities, one would expect variances.

Basically most of our measurements are not fine enough to make these fine adjustments. Take a slice of bread for example. How many of us take a standard count of 15 or 20 grams per slice? When you weigh these suckers, you'll find they can range from 12g to 27g. And that's for a standard loaf.

While I'm slowly moving towards this finer level of counting, most just estimate. I would never have in my younger years.

I never subtract for fiber, but I do a combo for the percentage to last over an hour or an hour and a half. On MDI I had to do a booster injection about an hour into it.

If I do subtract, I always get a late hit of glucose.

If I am snacking, I am stacking boluses like crazy and have to give myself a clear 3 hours at some point to make sure I am still on target.

Its interesting,I've seen this come up so often but I never consider fibre because its already subtracted on food labels and carb count books. In the UK its usually listed separately, in France many products don't include any count at all. Having said that I do find that largely vegetarian meals (high fibre) do make a difference taking longer to digest and that I often go low at 2 hours with a higher reading at 4 or 5 hours.

I wonder is carb counting always that acurate, or just what we think is right, and through experience works for us?

According to the AACDE if a product contains LESS than 6 grams of Fibre you do not remove it from the amount of carbohydrates, but if it DOES, then you are to subtract HALF the amount..
say a product is 30 grams of carb (cho) and has 5 gms of fibre, you count ALL the fibre in the carbs.. but if it has 10gms of fibre, you subtract 5 of those from the cho for a total of 25.
