What Are Net Carbs?
  • Low carb diets are based on the premise that certain carbohydrates contribute to blood glucose levels, while other carbohydrates do not.
     

  • Low carb diets consider certain carbs such as fiber and sugar alcohol “non-impact carbs”. Non-impact carbs are carbs that you can’t metabolize or use, so they don’t count, so to speak.
     

  • Net carbs are calculated by taking total carbohydrate grams and subtracting fiber and sugar alcohol grams. The remaining carb grams are considered a given product’s net carbs.

The proliferation of carbohydrate claims on food labels and menus should spur the Food and Drug Administration (FDA) to define "low-carb" and other carbohydrate claims, according to the nonprofit Center for Science in the Public Interest (CSPI).
 

Prohibit "net carb" claims. Manufacturers get "net carbs" or "impact carbs" by subtracting fiber, sugar alcohols, and other carbs that supposedly have "minimal impact on blood sugar."

"Is a carb that doesn’t raise blood sugar no longer a carb?"

"Consumers need to know that 'minimal impact on your blood sugar' does not necessarily mean 'minimal impact on your hips,'" cautioned Liebman. "People assume that they can't gain weight on foods with claims like 'carb aware' and 'carb smart,' just as they assumed that 'fat- free' on the package meant 'fat-free' on your waist. It's a huge leap of faith to assume that the calories in a lower-carb food don't count."
