Most dietitians, of course, scoff at the idea of eating pork rinds to lose weight. They point out that a half-ounce serving of pork rinds, about one cup, contains 5 grams of fat, 9 grams of protein and 80 calories, 0 carbs. That certainly is true, but a single serving of potato chips has 8 grams of fat, 11 grams of carbohydrates, 2 grams of protein and 140 calories.
