Carbs and Fibers

daryop · #1 (**permalink**) 03-24-2007, 06:03 PM

Is this calculation correct to figure out the dose?

Carbs = 35
Fibers = 5
Net Carbs = 35-5 = 30 Carbs.

That is the calculation I have been using for a very long time. But I am not sure if it is correct.

Looks good to me! I only subtract the fibre though if it's 5 or more grams.

I always subtract fiber...

I very rarely substract out the fiber from the total carbohydrate count. It has to be over 10g fiber before I do.

Cyborg............do you subtract even if there's only 1g of fiber?

I never subtract for fiber. I will end up with high blood glucose if I do. I am sure it is different for everyone. I do think your calculations are correct if you subtract for fiber.

I subtract out the fiber.

Yes, even if it's only 1g of fiber...

Why the threshold? Fiber is still fiber and interacts with your body the same way regardless of how much or how little there is, no? (If there is a threshold, doing it as a percentage seems more rational to me than a fixed amount - I would think it's more sensible to subtract the fiber in something with 5g carb/4g fiber than something with 100g carb/10g fiber. This would also avoid any games that may be played with serving sizes.)

And I'm with Cyborg, at least for now. I always subtract fiber, but I'm only a month into this, so I may find that not subtracting it or only subtracting a fraction of it works better for me.

If my insulin to carb ratio is x/10 (dinner) then eating something with 5 or more grams of fiber is going to change how much insulin that I need to take to cover the remaining carbs. On the other hand, if my ratio is x/15 (breakfast) and I eat something with only 1 or 2 carbs, then I hardly have to change my amount of insulin. I rewrote this 3 times and I feel like I'm still not being articulate! LOL! It makes sense in my world!

I always subtract out fiber (and I subtract 1/2 the sugar alcohols).

tanya, I understand what you are saying... if the fiber is such a small percentage you don't worry about it. and depending on what your ratio is for time of day, that percentage is different. I think the same way for snacks. If it's the morning, when my ratio is 1:45, I don't let 5 or 10 carbs bother me as a snack. but if that same snack was at dinner time, that would be half a unit, so i would dose for it.

For some reason, subtracting the fiber count of anything less than 10g doesn't work for me. I don't eat many food items that contain high fiber counts, so it's usually not a subtracting issue for me.

For example. Over the weekend I ate a Thomas's Light Multi-Grain English Muffin for breakfast with butter. One muffin contains 100 calories, 22 grams total carbohydrates, 8 grams fiber. I do NOT subtract the fiber out because two hours after eating I will test high and then two hours after that I will be within range.

Saturday 9am: 86 before, 165 at 11am, 90 at 1pm.
Sunday 8am: 85 before, 174 at 10:15am, 90 at noon

Had I subtracted out the fiber for the above example, I would have been much higher than the 165 and 174 two hours later. My guess is that I would have been into the 200's.

Monday 8:15am: 1/2 an english muffin and a small Dannon carb & sugar control yogurt. 75 before and 100 at 10am.

I'm best sticking with 1/2 an english muffin and a yogurt for breakfast, rather than an entire muffin.

OK, fair enough. I know better than to argue with empirical data.

I don't subtract for fiber.
I just make sure I have enough of something else...

Since the fiber does not contribute to bg, perhaps you need to increase your morning I:C ratio...
