Most low-carb diet followers, especially those on the ketogenic diet, can rejoice in the fact that cheese is a staple food that fits perfectly within their eating plan. Unlike high-carb foods, most natural cheese is rich in fat and protein while being very low in carbohydrates. However, not all cheeses are created equal. The carb content can vary significantly based on the type of cheese, its age, and its processing, making it crucial to understand the differences.
Why is cheese typically low carb?
The carbohydrate content of cheese primarily comes from lactose, the natural sugar found in milk. The cheese-making process involves a fermentation stage where bacteria consume most of the lactose, converting it into lactic acid. The whey, which contains most of the remaining lactose, is then separated from the solid curds. The longer a cheese is aged, the more time the bacteria have to break down the lactose. This is why aged, hard cheeses have a negligible carbohydrate count, whereas fresher, softer cheeses contain slightly more.
The best low-carb and keto-friendly cheeses
For those seeking the lowest possible carbohydrate count, focusing on hard, aged, and full-fat cheese is the safest bet. Full-fat varieties are preferred because they contain a higher fat-to-protein ratio and don't require the carb-based thickeners sometimes found in low-fat versions.
- Parmesan: A hard, aged cheese with a sharp, nutty flavor. It is one of the lowest-carb options available, with less than 1 gram of carbs per ounce. Perfect for grating over dishes or making into crispy snacks.
- Cheddar: This classic is very low in carbs, especially the aged varieties. A mild cheddar contains less than 1 gram of carbs per ounce.
- Goat Cheese (Chèvre): Creamy with a distinct tangy flavor, goat cheese is another excellent low-carb choice. A typical 1-ounce serving has only around 0.3 grams of carbs.
- Brie and Camembert: These soft, creamy cheeses are surprisingly low in carbs, with only about 0.1 grams per ounce, making them ideal for a rich, satisfying snack.
- Blue Cheese: The strong, pungent flavor of blue cheese offers great satisfaction with minimal carbs, around 0.7 grams per ounce.
- Swiss: Another reliable low-carb choice with around 1.3 grams of carbs per 100g, though carb counts can vary slightly.
- Cream Cheese: A keto favorite, full-fat cream cheese is very low in carbs, making it suitable for both sweet and savory recipes.
Cheeses to approach with caution on a low-carb diet
Some cheeses, while still relatively low in carbs compared to non-dairy foods, should be consumed more cautiously on a strict low-carb or keto diet.
- Cottage Cheese: While high in protein, cottage cheese contains more lactose than many other cheeses. A half-cup serving of full-fat cottage cheese can have around 5 grams of carbs, so portion control is important. Be especially wary of low-fat or non-fat versions, which often contain added carbs.
- Ricotta: Similar to cottage cheese, full-fat ricotta is higher in carbs, around 9 grams per half-cup, making it necessary to watch your serving size.
- Processed Cheese: Items like American cheese slices and spray cheese are often filled with stabilizers, emulsifiers, and whey powder that can significantly increase the carb count. For example, a single slice of American cheese can account for a considerable percentage of a strict keto diet's daily carb limit.

| American Cheese | ~2g | ~5g | Poor (Processed, higher carbs) | 
How to incorporate cheese into a low-carb lifestyle
For most, cheese can be an incredibly versatile and flavorful addition to a low-carb diet. Its rich fat and protein content promotes satiety, helping to curb cravings for higher-carb foods.
Here are some ideas for including cheese in your low-carb meals:
- Homemade cheese crisps: Simply bake small piles of shredded hard cheese, like Parmesan or cheddar, on parchment paper until golden and crispy.
- Low-carb wraps: Use melted, cooled cheese to form thin, pliable wraps for fillings.
- Toppings for vegetables: Sprinkle shredded cheese over roasted broccoli or cauliflower for a cheesy, comforting side dish.
- Rich sauces: Create creamy, high-fat sauces for meat and vegetables using cream cheese or aged cheddar.
- Fat bombs: Combine cream cheese with other low-carb ingredients like nuts or flavorings for a quick, energy-boosting snack.
Conclusion
Ultimately, the question, 'is cheese low carb friendly?' has a positive answer for those on low-carb and keto diets, provided they make smart choices. Natural, full-fat cheeses, especially hard and aged varieties, are the best options due to their minimal carb content. You should exercise caution with cheeses that contain more lactose, like cottage cheese and ricotta, and actively avoid highly processed cheese food products. By paying attention to the type of cheese and practicing portion control, you can easily enjoy this delicious and versatile food while adhering to your low-carb goals.
