I'm munching on a "Thnk Thin - Low Carb Diet" bar for lunch.

On its label it says:

NET CARB COUNT 2
Total carbs: 22
Non impact carbs: -20
Net carb count: 2
Note: For those watching their carbs, count only 2 grams, as all other carbs, including fiber, have a minimal impact on blood sugar.

The more I think about it, this sounds like a convenient marketing ploy to get their "candy bar" to list a lower carb count than the competition, even when the two products are essentially the same thing. The big "2" on the label is certainly why I bought the product over its competition.

Anyone know about this stuff and whether or not it's really true? Or is it just marketing BS?
