A quick way to estimate hidden carbs.

From my bag of rinds:

Total Calories: 80
Calories from Fat: 45
Protein: 9g
Carbs: 0g
Fiber: 0g

Take the total calories and subtract the calories from fat.

That gives me 35.

Divide the result by 4. This gives you the number of grams of protein, carbs and fiber.

The result here is just under 9g. (8.75g)

Now subtract the protein grams and the fiber grams and what's left is a decent estimate of the carb grams you should count. In this case it comes out negative so count it as zero.

There are both rounding errors in the labelling and errors in the assumption that there are 4 calories per gram of protein and carbs. But this will identify foods that have significant hidden carbs in them.

And with just a little practice it's something that is very easy to do in your head looking at the package in the store.

Watch out for other flavors of pork rinds - some of them add considerable sugar. Also, just because pork rinds are OK to eat, doesn't mean that you will like them. I sure don't. You can develop a taste for them and you can also use them in other recipes as a breading substitute.
