Wow! With 16 grams of fat, I'd say they're far from 98% fat free...which is almost 68% of your calories from fat in this product.

Okay...we have:

16 grams of fat x 9 calories per gram = 144 calories
16 grams of protein x 4 calories per gram = 64 calories

total so far is 208 calories which leaves..

2 calories from carb (or less than 1 gram).

It looks like the math adds up and these really do have less than 1 gram of carb per serving.
