What Makes a Cheese Low Carb?
When following a low-carb diet like the ketogenic diet, the goal is to limit carbohydrate intake while focusing on healthy fats and protein. Cheese is a dairy product made from milk, and its carb content depends largely on how it's processed and aged. The primary carbohydrate in milk is lactose, a type of sugar. During the cheesemaking process, bacteria consume the lactose, which means that aged cheeses, where more fermentation has occurred, will have a lower lactose and therefore lower carb content. This is why hard, aged cheeses are often the most recommended for strict low-carb diets.
Conversely, fresh and processed cheeses may contain more carbohydrates. Fresh cheeses like ricotta and cottage cheese have a higher moisture content and less lactose fermentation, resulting in slightly higher carbs. Processed cheese food, such as American cheese, often has added ingredients and emulsifiers that increase its carb count and should be avoided on a clean keto diet.
Top Hard and Aged Cheeses
Hard, aged cheeses are the undisputed champions of low-carb snacking. Their minimal carb counts and rich, concentrated flavor make them a staple in any keto kitchen. The aging process also makes them more suitable for individuals who are sensitive to lactose.
Parmesan
Aged for a minimum of 10 months, Parmesan is a hard Italian cheese with a distinct sharp, nutty flavor. With nearly 0.9 grams of net carbs per ounce and a good dose of protein, it's an excellent topping for salads or low-carb pasta dishes, or a great snack on its own.
Cheddar
One of the most popular and versatile cheeses, aged cheddar is a fantastic low-carb choice, boasting approximately 0.4 grams of net carbs per ounce. It is rich in healthy fats and comes in various ages and sharpness, offering a wide range of flavor profiles for snacking, melting, or adding to recipes.
Swiss
Known for its characteristic holes and mild, nutty flavor, Swiss cheese is very low in carbohydrates, with just about 0.4 grams of net carbs per ounce. It is great for sandwiches or for melting over low-carb burgers.
Gouda
This Dutch cheese is known for its sweet, buttery, and slightly nutty flavor. An ounce of Gouda has only about 0.6 grams of net carbs, making it a delicious and satisfying option. Aged Gouda develops a deeper, richer flavor.
Soft and Creamy Low-Carb Cheeses
For those who prefer a creamier texture, several soft cheeses also have impressively low carbohydrate counts, making them suitable for low-carb diets.
Brie and Camembert
These soft, French cheeses with a bloomy rind are excellent for spreading and pairing with low-carb crackers. Brie has as little as 0.1 grams of net carbs per ounce, while Camembert is similarly low, with around 0.1 grams per ounce.
Goat Cheese
Tangy and creamy, goat cheese offers a unique flavor that works well in salads or omelets. It typically has around 0.4-0.6 grams of net carbs per ounce.
Cream Cheese
A classic for low-carb baking and fat bombs, cream cheese is high in fat and low in carbs, with about 1.2 grams of net carbs per ounce. Just be mindful of portion sizes due to its caloric density.
Mozzarella
This mild and versatile cheese is great for melting and features a relatively low carb count, with around 0.6 grams of net carbs per ounce. It is a keto staple for homemade pizza or caprese salads.

Which Cheeses to Use and Which to Limit
While most natural cheeses are low in carbohydrates, it is essential to be discerning, especially if you are on a strict low-carb or keto diet. The key is to check nutritional labels and avoid processed versions with hidden sugars and starches. As a rule, the more aged and natural the cheese, the lower its carb content will be. Soft, fresh cheeses like cottage cheese and ricotta can be included, but in moderation, as they contain more lactose and carbs compared to their aged counterparts. Processed cheese slices and spreads, often labeled as 'cheese food,' should be avoided as they contain emulsifiers and other additives that raise the carb count.
The Role of Cheese in a Low-Carb Diet
Cheese provides more than just flavor to a low-carb diet. It is an excellent source of several key nutrients. Cheese is high in fat, which is essential for providing energy and satiety when on a keto diet. It is also a great source of protein, helping with muscle maintenance and repair. Furthermore, cheese provides vital micronutrients like calcium for strong bones and teeth. Choosing a variety of cheeses can ensure you get a broad spectrum of nutrients and flavors while adhering to your low-carb goals.
Conclusion: Finding the Best Cheese for Your Low-Carb Needs
Determining what's the best cheese to eat on a low carb diet ultimately comes down to personal preference and dietary goals. For the lowest possible carb count, focus on hard, aged cheeses like Parmesan and Cheddar. For creaminess, opt for Brie or goat cheese. No matter your choice, most natural, full-fat cheeses are a delicious and nutrient-dense addition to a low-carb eating plan, so long as you are mindful of portion sizes due to their calorie content. By prioritizing natural and unprocessed varieties, you can enjoy a wide array of flavors without compromising your low-carb lifestyle.
