Cyclical or targeted ketogenic diets are more advanced methods and primarily used by bodybuilders or athletes. The ketogenic diet is a very low-carb, high-fat diet that shares many similarities with the Atkins and low-carb diets. Since the keto diet is all about getting in fat, you get less fat per serving with the whipped version instead of the regular block. For example, the whipped version of the Philadelphia Cream Cheese contains 4 grams of fat in a single serving, while the block cream cheese contains 7 grams per serving . Look for the rectangular blocks of cream cheese rather than the plastic containers.
