Understanding Carbs in Cheese
To identify the lowest carb cheese, it's essential to understand where the carbohydrates in cheese come from. The primary carbohydrate source in dairy products is lactose, a milk sugar. During the cheesemaking process, most of the lactose is removed along with the whey. For aged cheeses, the remaining lactose continues to break down over time, further reducing the carbohydrate content. This is why hard, aged cheeses are often lower in carbs than fresh, soft cheeses.
The Absolute Lowest Carb Cheeses
While very few cheeses are completely zero-carb, some come exceptionally close. The carb content can vary slightly by brand and aging time, but here are some of the lowest carb options based on a typical 1-ounce (28g) serving:
- Brie & Camembert: These soft-ripened cheeses are often considered the lowest carb varieties, with some sources citing as low as 0.1g per ounce.
- Goat Cheese (Chèvre): A tangy and creamy option, goat cheese is also extremely low in carbs, typically around 0.3g per ounce.
- Cheddar: A popular and versatile cheese, cheddar is reliably low in carbs, with about 0.4g per ounce.
- Blue Cheese: This flavorful cheese is another excellent low-carb choice, containing approximately 0.7g per ounce.
- Parmesan: A hard, salty Italian cheese perfect for grating, Parmesan has very few carbs, often around 0.9g per ounce.
- Gruyère: This Swiss-style hard cheese also boasts an impressively low carb count, with approximately 0.1g per ounce.
When seeking the lowest carb cheese, opt for full-fat, natural versions. Some lower-fat cheeses add gums or thickeners to replace the texture lost by removing fat, which can increase the carb count.

This table compares the nutritional content of a standard 1-ounce (28g) serving of various cheeses, highlighting their carbohydrate content.
| Cheese Type | Carbs (g) | Fat (g) | Protein (g) | 
|---|---|---|---|
| Brie | 0.1 | 8 | 6 | 
| Camembert | 0.1 | 7 | 6 | 
| Gruyère | 0.1 | 9 | 8.5 | 
| Goat Cheese | 0.3 | 9 | 6 | 
| Cheddar | 0.4 | 9 | 7 | 
| Blue Cheese | 0.7 | 8 | 6 | 
| Parmesan | 0.9 | 7 | 10 | 
| Mozzarella | 1.0 | 6 | 6.3 | 
| Swiss | 1.5 | 8.6 | 7.5 | 
| American (Processed) | 2.0 | 6.6 | 4.9 | 
Which Cheeses to Limit or Avoid
While many cheeses are low-carb, some varieties are less suitable for strict low-carb or ketogenic diets due to higher carb counts, lower fat content, or the presence of additives.
Fresh Cheeses
Fresh cheeses like cottage cheese and ricotta have not undergone the same aging process as hard cheeses, meaning more of their original lactose remains. A half-cup serving of full-fat cottage cheese contains around 5 grams of carbs, which is significantly higher than most hard cheeses. While still relatively low, these require more careful portion control.
Processed Cheeses
Processed cheese products, such as American cheese singles or cheese spreads, are generally best to avoid on a low-carb diet. These products often contain added ingredients like emulsifiers, fillers, and thickeners that increase their carbohydrate content. They also provide less nutritional benefit compared to natural cheese.
Low-Fat Cheeses
For a keto or high-fat, low-carb diet, low-fat or fat-free cheeses are not ideal. These products strip away the fat—which is the main calorie source in a keto diet—and sometimes replace it with fillers or starches to maintain texture, resulting in a higher carb count than their full-fat counterparts.
How to Use the Lowest Carb Cheeses
Integrating low-carb cheeses into your meals is simple and adds great flavor and fat content. Consider these ideas:
- Snacks: Enjoy a few slices of cheddar or a piece of brie with nuts or seeds.
- Salads: Crumble blue cheese or goat cheese over a green salad for a powerful flavor boost.
- Melting: Melt Gruyère or cheddar over eggs, lettuce-wrapped burgers, or steamed vegetables like broccoli and cauliflower.
- Sauces: Use cream cheese as a base for creamy, high-fat sauces for meat or vegetables.
- Crisps: Create savory cheese crisps by baking small piles of shredded Parmesan or cheddar until golden and crispy.
- Baked Dishes: Use low-carb cheese as a topping for casseroles or stuffed chicken breasts.
Conclusion
For those following a low-carb or keto diet, cheese is a delicious and versatile food that can easily fit into your meal plan. The key is to be selective. Focus on natural, full-fat, aged varieties like Brie, Camembert, Gruyère, and Parmesan for the absolute lowest carb counts. By avoiding processed cheese products and watching the portion sizes of fresh cheeses, you can enjoy all the flavor and nutritional benefits without compromising your dietary goals.

How the Aging Process Affects Carb Content
The longer a cheese is aged, the lower its carbohydrate content tends to be. This is because the bacteria used in the fermentation process have more time to consume the lactose, breaking it down into lactic acid. This process is what gives aged cheeses their characteristically sharp or complex flavor profiles. Fresh cheeses, like cottage cheese and ricotta, are not aged and therefore retain more lactose and, consequently, more carbs.
Choosing Full-Fat for a Lower Carb Count
Contrary to common assumptions, opting for full-fat cheese is often the best strategy for minimizing carb intake on a low-carb or keto diet. Low-fat and fat-free versions replace the removed fat with other ingredients to maintain taste and texture. These ingredients are often starchy fillers or gums that can increase the cheese's carbohydrate total. The higher fat content also helps with satiety, which is beneficial for managing appetite on a low-carb plan.
Natural vs. Processed Cheese
One of the most important distinctions for a low-carb lifestyle is between natural and processed cheese. Natural cheeses are made with simple ingredients (milk, salt, cultures, rennet), while processed cheese foods contain a laundry list of added ingredients. These additives can include whey powders, oils, and other fillers that significantly increase the carb count. Always check the ingredients label to ensure you are getting a natural cheese product that aligns with your dietary needs.
How Serving Size Influences Carb Intake
Even with a very low-carb cheese, portion control is still important. While a single ounce may contain less than a gram of carbohydrates, eating multiple servings can quickly add up. Because cheese is also calorically dense, enjoying it in moderation helps manage overall calorie intake while providing key nutrients and flavor. For example, three ounces of a cheese with 0.9g of carbs per ounce will add 2.7g of carbs to your meal, which is still quite low, but a larger portion would impact your daily total more substantially.
The Role of Cheese in a Balanced Low-Carb Diet
Aside from being low in carbs, cheese is a great source of other important nutrients. Aged hard cheeses like Parmesan are packed with calcium, zinc, and protein. The protein in aged cheese is also easily digestible because it is pre-broken down during the maturation process. Incorporating low-carb cheeses can help round out a diet by providing these essential nutrients in addition to healthy fats, which are a cornerstone of a ketogenic lifestyle.
Creative Ways to Enjoy Low-Carb Cheese
Beyond snacking, low-carb cheeses can be used in a variety of culinary applications. Use shredded Gruyère or cheddar in a keto mac and cheese with cauliflower florets. Make a creamy, cheesy dip using cream cheese and blue cheese for dipping celery sticks. The possibilities are endless for adding flavor and healthy fats without excess carbs.
The Benefits of Grass-Fed Cheese
For those seeking the highest quality cheese, looking for grass-fed options is a great choice. Cows that are fed a grass-based diet often produce milk with a superior nutrient profile. This results in a higher quality cheese that provides more nutrients and a richer flavor. Opting for high-quality, full-fat cheeses from responsible sources can further enhance the nutritional benefits of incorporating cheese into your low-carb lifestyle.
Conclusion: Selecting Your Low-Carb Cheese
In summary, the key to finding the lowest carb cheese is to favor natural, full-fat, aged varieties. Cheeses like Brie, Camembert, Goat Cheese, Cheddar, and Parmesan offer minimal carbs, making them perfect for low-carb and keto diets. Be mindful of fresh cheeses, which have slightly higher carb counts, and avoid processed and low-fat versions that contain unwanted fillers. By making informed choices, you can continue to enjoy the delicious and nutritious benefits of cheese while sticking to your dietary goals.
