Fit day and fiber question

On fit day I track everything I eat. Now if a food has 15g carbs and 5g fiber, does this mean that 5 of those 15g carbs are fiber, or does it mean that there are 15g carbs (that the body can actually "use") and 5g in addition, which is fiber?

And how how are foods normally labeled with regards to the same question? I'd thing it is the first one, but I'm not sure..

it is annoying because the website I use to see what my food contains can sometimes have 5g carbs and 10g dietary fiber. So if fit day is the first way I described then I should put in 15g carbs and 10g fiber.. or?
 
I'm pretty sure that fibre isn't included in their figures for carbs so it should be 15g of carbs and 5g of fibre

If I'm wrong then I've been reading nutritional info wrong for some time now :)
 
On fitday, if you have carbs for say 50% of the calorie value with let's say 10g carbs and 0g fiber. If you then add fiber, that 50% will go down, so this means that fitday does count fiber in the main carbs thing. The food table I use does not do this (because often there is more fiber than carbs) so I guess it is usual for nutrition info to regard fiber as its own thing, while fitday counts it along with carbs..
 
another thing I just noticed.. I think there is a bug in the carbs and fiber thingy. If I put in 100g of carbs it comes up as 400 calories, which is correct if I then put in 50 of those as fiber it goes down to 200, which is correct. Now if I delete the 50 input on the fiber, the 100 carbs jump up to be 800 cals, however, if I input zero, it will go back to being 400.. weird..

It's not a bug.
The fiber and the carbs cancel eachother out, thus, more fiber means less cals.
So if you have a product with 0 protein, 0 fat, 10g carbs and 10g fiber, then the product will be with zero calories... no calories at all



Look up this article, It contains various 0 calorie foods like noodles, caramel dip... etc...
 
I don't think you read that right.
if I have a food with 10g carbs the calories will be 40 (1 g of carbs contains 4 calories) if I put in 10 for fiber, it will be 0 calories, which is correct, I only said this to prove that fitday puts your carbs and fiber together, while a lot of nutrition info tables puts them as separate. However, when I delete the 10g fiber entry, the calories pop up to 80, so it says 10g carbs = 80 cals, which is wrong, but when I put 0 back in it's back to normal :p

I misunderstood your first post, that doesn't sound right, they probably have some kind of a bug :eek:
 
jupp it was weird. I tried it over and over again and I got 8 g cals per 1g carbs.. however, now I can't do it anymore.. I seem to get 404 instead of 400 cals though.. weird
 
In the U.S they do list fiber and cals together. The new thing is 31g carbs/21g fiber NET CARBS (they announce it) =10g. Same thing with sugar alcohols.

But you're in a different country so they may do it differently. Obviously if something says 5g total with 10g fiber, it isnt counting fiber.
 
right, they don't count the fiber grams as carbs...at least in the US

whoa, hold on a second.

If a label reads 10 g carbs and 5g fiber that means it has 10g total carbs and 5g taken out as fiber..... so 5g net carbs....

RIGHT? that is how I have always thought it was.

It's not 15 total carbs with 5g being fiber..... right?
 
that's how it is in the US, according to these people, yes. but fit day seems to do it differently :p
