The ketogenic diet, a nutritional plan that emphasizes high fat and very low carbohydrate intake, allows many types of cheese due to their favorable macronutrient profile. However, not all cheese is created equal, and understanding the nuances is key to staying in ketosis. The best cheese for a keto lifestyle is typically high in fat, moderate in protein, and contains minimal carbs, often derived from lactose.
The Best Keto Cheeses
When choosing cheese for a ketogenic diet, the goal is to select full-fat, unprocessed varieties with the lowest possible carbohydrate count. The aging process for cheese plays a significant role, as lactose (milk sugar) is converted to lactic acid over time, reducing the carb content. Harder, aged cheeses generally have lower carbs than their softer, fresher counterparts. Here are some of the top choices:
- Cheddar: This popular cheese comes in many varieties, from mild to extra sharp. One ounce of mild cheddar contains less than 1 gram of carbs, along with 9 grams of fat and 7 grams of protein. Its versatility makes it perfect for snacking or melting.
- Gouda: A slightly sweet, creamy cheese that is also an excellent keto choice. Gouda has a low carb count and a high fat content, making it great for melting onto dishes or enjoying on its own.
- Goat Cheese (Chèvre): Known for its tangy flavor, goat cheese is low in carbs and also often easier to digest for those with lactose sensitivity. An ounce of goat cheese provides around 8 grams of fat and 6 grams of protein with minimal carbs.
- Blue Cheese: This pungent cheese, developed with specific molds, offers intense flavor with a creamy texture. Varieties like Gorgonzola are very low in carbs and high in healthy fats, perfect for salads or dips.
- Parmesan: A hard, nutty-flavored cheese that is a keto superstar, with zero or minimal carbs per serving. It's excellent for grating over meals to add a salty punch of flavor without the carbs.
- Cream Cheese: A very popular and versatile keto cheese, cream cheese is high in fat and low in carbs, making it ideal for making keto-friendly desserts, dips, or spreads.
- Brie: This soft, creamy cheese has a high fat content and very few carbs, pairing wonderfully with nuts or low-carb crackers.
- Swiss and Gruyère: These flavorful, harder cheeses are also great options. One ounce of Swiss cheese has approximately 1.5 grams of carbs, while Gruyère is even lower, with around 0.1 grams.
Cheeses to Limit or Avoid on Keto
While most natural, full-fat cheeses are acceptable, some types should be approached with caution or avoided altogether on a strict ketogenic diet:
- Low-Fat and Non-Fat Cheeses: The keto diet relies on a high fat intake for energy. Low-fat and non-fat cheeses remove the essential fat and often contain added fillers, gums, or starches that increase the carbohydrate load.
- Processed Cheeses: Items like individually wrapped cheese slices and canned cheese spreads are highly processed and contain undesirable additives, colors, and preservatives. These offer little nutritional value and should be avoided.
- Pre-Shredded Cheese: Many pre-shredded varieties contain anti-caking agents, such as potato starch, which add extra carbs. It is best to buy cheese in a block and shred it yourself.
- Cottage Cheese: While known for its protein content, cottage cheese has a higher carbohydrate count due to its lactose content. A half-cup serving of full-fat cottage cheese can have around 5 grams of carbs, which can quickly add up. It is best to consume this in very small, measured portions if at all.
- Ricotta Cheese: Similar to cottage cheese, ricotta contains a higher amount of lactose and is higher in carbs compared to harder cheeses.

Tips for Incorporating Cheese into Your Keto Diet
- Prioritize Full-Fat: Always opt for full-fat, unprocessed versions of cheese. The higher fat content is crucial for staying in ketosis, and you avoid unwanted additives.
- Watch Your Portions: While keto-friendly, cheese is calorie-dense. Keep track of your intake to avoid accidentally exceeding your daily calorie goal, especially if weight loss is your aim.
- Consider Quality: Whenever possible, choose organic and grass-fed cheese. This can provide more beneficial omega-3 fatty acids and other nutrients.
- Read Labels: Be vigilant about reading nutritional labels, especially for fresh or flavored cheeses, as carb counts can vary between brands. Check for added sugars or starches.
- DIY Shredding: To avoid the added starches and anti-caking agents, buy cheese in a block and shred or slice it yourself at home.
- Creative Pairings: Pair cheese with other keto-friendly foods like low-carb vegetables, nuts, or seeds for a satisfying snack or meal.
Conclusion
For those on a ketogenic diet, cheese can be an excellent and delicious source of high-quality fat and protein, provided you choose wisely. Hard and aged cheeses like cheddar, Parmesan, and Gruyère are typically the safest bets due to their low lactose content. Soft and creamy options like cream cheese and brie are also great, as long as they are full-fat and free of additives. Processed, low-fat, and some high-lactose cheeses like cottage cheese should be limited or avoided. By focusing on whole, unprocessed cheese and being mindful of portion sizes, you can continue to enjoy cheese as part of a successful keto lifestyle.
