you would have to read the ingredient list to see is there are sugar alcohols in it. besides that, my next best guess would be rounding. 4.6 would be rounded up to 5. so that would take care of 1.6 cals of the difference, which would round up to 2. also, if fiber were .4, it would show as 0, but would still take out .4 g of carbs. so if there were only 4.6 carbs -.4 carbs, you'll get 4.2 carbs, multiply that out by 4 and get 16.8 cals.

When I came to Texas earlier in the year I brought home some Smuckers Sugar Free Jelly.
The calories per tablespoon are 10 Zero Fibre The carbs per tablespoon are 5
So that doesn't add up... 5g x 4 calories = 20 calories.
Are the ingredients sugar alcohols or something that doesn't get used as normal carbs?
