Since Maltodextrin is the only net carb in there, and sugars are listed as 0g...each Popsicle would have <1g of net carbs. Glycerine is not a carb. But, under the FDA's difference formula, anything that's not a Lipid, Amino Acid, Water, Ash (Vitamin/Mineral), or Ethyl Alcohol is counted as a carb. A very small number of folks are sensitive to Glycerine. Unless you stall out, I wouldn't worry about it.

On a side note, those contain Aspartame which Dr. A does not allow on his diet because it causes cravings/stalling [in a large number of folks] and causes horrible migraines and other problems.
