Fiber deductions


Quote  |  Reply
Some calorie counting books and articles recommend deducting 9 calories from your daily total for every gram of fiber you eat.  (I'm sorry, I don't have the references.  This was something a friend and I discussed months ago.)
I've never really done that, but I was tracking my fiber intake and I get, on average, 40 grams of fiber a day.  Am I starving myself?

Does anyone have an answer to this? I read something similar myself recently and was wondering if there was any truth in it. I eat about 30-35g of fiber a day so should I be deducting 270+ calories from what i've eaten? Because I don't often eat more than my minimum calorie requirements and if i'm down 270cals from where I think I am then my deficit's too high.

i have some friends who use Weight Watchers and i know that the more fibre that a food has, the fewer points it is.

for example:

a 100 calorie piece of bread with no fibre may be 2 points while a 100 calorie piece of bread with 3 grams of fibre is one point.  so if a person is allowed to eat 25 points worth of food each day then they can definitely consume more calories if they eat low fat, high fibre foods.

It might be the case for WW, but as far as I know for counting calories, just focus on total calories. I am happy to blindly trust that if fiber should be discounted from the total calories, CC's food log would do that for me.

I'm sure a better answer would have to do with insoluble and soluble fiber, but I don't know enough about that, and I'm not sure many nutrition labels differentiate to be able to better calculate.

Also, I'm not sure why it would be 9 calories, since a gram of carbs (which is where fiber gets counted) is 4 calories.

I think the calories from fiber are already deducted from most packaged foods in the US, but this is not the case in every other country.  This is why Canadian and US foods might be exactly the same but have different calorie counts in the nutrition information.  The reason the calories are deducted is that you aren't actually absorbing any of the calories from the fiber, so it makes sense that a deduction is made, but in general if you deduct from foods when you're already receiving a modified calorie count, you'll have a lower than actual calorie count for the day.

Does anyone know if this is the case in the UK?
