The amount of pork rinds you can eat on the ketogenic diet depends on your macros and how much daily net carbs you prefer to consume.
Generally, two ounces (or about 27 grams) of regular-flavored pork rinds contain approximately zero grams of net carbs.
This means that if your daily carb limit is around 20 grams or lower for the day, then two ounces of pork rinds would fit into your diet. However, always read labels and ingredient lists before purchasing to ensure that the product has no added sugars or artificial sweeteners.
