What's a Net Carb?
Manufacturers get "net carbs" or "impact
carbs" by subtracting fiber, sugar alcohols, and other carbs that supposedly have "minimal impact on blood sugar."
links below are news links; and one of them has an awesome quote:
"The basic concept is not all carbs are created equal,"
said Crawford. "Some have an impact on your body's metabolism, some do not."

What's a Sugar alcohol?
For those who don't know; a sugar alcohol is effectively
any sugar substitute - some of which are ok (sucralose - aka Splenda - has no calories; and isn't really digested by the body);
and some of them need more attention paid - think fructose (fruit sugars) which can impact your blood sugar and TOTALLY impact
your carb count. Sugar Alcohols contain anywhere from 2.1
calories per gram to 4 calories per gram.
There's research ongoing about these things; but the current
results seem to be mixed. They taste sweet; so for some people they help you stay on a low sugar / low carb diet; but other
people report increased carb cravings from them; and if you assume they're all good and all the same you can get burned...
There's a nifty side effect to a bunch of these - they can stimulate... Um... "gastric distress" - meaning many of
them have a laxative effect...
The trick at that point is to read the actual list of ingredients and find out which
sugar alcohols they are using; because that will have a direct impact on whether you want to try it or not.
