Understanding Carbs in Cheese
Cheese is primarily composed of protein and fat, with carbohydrates coming from lactose, the natural sugar found in milk. During the cheesemaking process, most of the lactose is removed with the whey. What remains is further broken down by bacteria during fermentation and aging. This is why aged, hard cheeses typically have the lowest carb content, while fresher, softer cheeses retain more lactose and thus have a higher carb count. Processed cheeses should generally be avoided, as they often contain added starches, thickeners, and preservatives that significantly increase their carbohydrate load.
The Lowest Carb Cheeses
For those seeking the absolute lowest carb options, hard and aged varieties are your best bet. A little goes a long way with these intensely flavored cheeses, making them satisfying additions to any meal or snack.
-
Parmigiano Reggiano / Parmesan
Often cited as having zero or near-zero carbohydrates, genuine Parmigiano Reggiano is a low-carb champion. Its long aging process effectively eliminates residual lactose. It’s perfect for grating over low-carb pasta dishes, salads, or baking into crispy cheese crackers.
-
Aged Cheddar and Gruyère
Sharp, aged cheddar and nutty Gruyère are excellent low-carb choices, typically containing less than 1 gram of carbs per ounce. The longer they are aged, the lower their carb content becomes.
-
Brie and Camembert
These soft, creamy, and flavorful cheeses are also very low in carbohydrates, with figures often reported around 0.1 to 0.5 grams per ounce. Their intense flavor means you don't need much to feel satisfied.
-
Goat Cheese (Chevre) and Feta
Goat cheese is a fantastic low-carb option, with some varieties containing 0 carbs per ounce, and often boasting excellent ratios of fat and protein. Feta, another low-carb cheese made from sheep's or goat's milk, adds a salty tang to salads and dishes.
Moderate Low-Carb Cheeses to Enjoy
While slightly higher in carbs than their aged counterparts, these cheeses are still excellent choices for a low-carb diet and offer great versatility.
-
Mozzarella
Fresh mozzarella, especially the low-moisture kind, is a mild, low-carb cheese with less than 1 gram of carbs per ounce. It's a versatile choice for low-carb pizza, caprese salad, or melted into dishes.
-
Blue Cheese
Known for its pungent flavor, blue cheese typically contains less than 1 gram of carbs per ounce. The molds used in its creation consume some of the lactose, contributing to its low carb count.
-
Cream Cheese
A keto dieter's favorite due to its high fat content and versatility, cream cheese has a modest carb count, typically around 1 gram per ounce. Just be sure to choose a full-fat, unprocessed version and check the label for added sugars.
The Cheeses with Higher Carb Counts
Not all cheeses are created equal. Some popular varieties retain more lactose and, therefore, more carbohydrates, making them less ideal for strict low-carb diets.
-
Ricotta and Cottage Cheese
These fresh, soft cheeses have higher moisture and lactose content than aged cheeses. A half-cup serving of ricotta can contain 9 grams of carbs, while cottage cheese contains around 5 grams. While higher in protein, they should be eaten in moderation on a keto diet.
-
Processed Cheeses
Processed cheeses like American slices, cheese spreads, and pre-shredded bags are typically higher in carbs than natural cheese. Manufacturers often add starches, fillers, and preservatives that increase the carb load. It's best to avoid these and opt for whole, minimally processed cheese blocks.

Health Benefits of Low-Carb Cheeses
Beyond being low in carbohydrates, high-quality, full-fat cheeses offer numerous health benefits.
- Rich in Nutrients: Cheese is an excellent source of protein, calcium, and vitamin D, which are crucial for bone and muscle health.
- High in Protein and Fats: These macronutrients are very satiating, helping you feel fuller for longer and reducing overall calorie intake. This is particularly beneficial for those following a low-carb diet for weight management.
- Contains Healthy Fatty Acids: Cheese from grass-fed cows contains conjugated linoleic acid (CLA), a healthy fatty acid with potential anti-inflammatory benefits.
- Promotes Gut Health: Many cheeses are fermented foods containing probiotic bacteria, which support a healthy gut microbiome.
Tips for Incorporating Cheese into Your Low-Carb Diet
To make the most of cheese while keeping your carb count low, follow these guidelines:
- Prioritize Aged, Hard Cheeses: Focus on varieties like Parmesan, aged cheddar, Gruyère, and Swiss for the lowest carb content.
- Opt for Full-Fat: For a low-carb or keto diet, full-fat cheeses are more satiating and typically have lower carb counts than their reduced-fat counterparts, which may have added ingredients.
- Check Labels: Always read nutrition labels, especially for fresh or processed cheeses, to spot hidden sugars, starches, or fillers.
- Use it for Flavor: Use strong-flavored cheeses like blue cheese or sharp cheddar sparingly to add a powerful taste without adding many carbs.
- Get Creative with Recipes: From cheese crisps to baked cheese dishes, low-carb recipes abound for incorporating your favorite low-carb cheese.
Conclusion
For those on a low-carb or ketogenic diet, cheese is a valuable nutritional ally. The key is to understand that not all cheeses are the same. By selecting hard, aged cheeses like Parmesan, aged cheddar, and Swiss, and enjoying soft, low-carb options like Brie and Camembert in moderation, you can add delicious flavor and important nutrients to your diet without compromising your carb goals. Always read labels and be mindful of portion sizes, particularly with fresh or processed cheese, to ensure your meal plan stays on track.
