4 min read

Over 55% of the calories in a ketogenic diet typically come from fat, making high-fat foods like cheese a primary component of the eating plan. Knowing which cheeses to choose is key for staying within your low-carb limits and successfully achieving ketosis.

Quick Summary

This guide examines a variety of cheese types to determine their keto-friendliness, based on carb count, fat content, and processing levels. We review excellent low-carb options and identify which ones to consume sparingly or avoid completely for best results on the ketogenic diet.

Key Points

Prioritize full-fat cheese: To align with ketogenic principles, choose full-fat cheese over low-fat or nonfat versions, which often contain more carbs and additives.
Hard and aged cheeses are lowest in carbs: Aged cheeses like Parmesan and Cheddar typically have less lactose, resulting in a lower carb count.
Avoid processed cheese products: Steer clear of American cheese slices and spray cheese, as they are heavily processed with non-keto ingredients.
Consume fresh cheeses in moderation: While not off-limits, softer, fresh cheeses like ricotta and cottage cheese contain more carbs and should be portion-controlled.
Read nutrition labels carefully: Always check for hidden carbs or added starches, especially in pre-shredded or flavored cheese products.

Understanding the Role of Cheese in a Ketogenic Diet

For followers of the ketogenic diet, cheese can be an excellent food choice due to its high fat, moderate protein, and low carbohydrate content. The fermentation process in cheesemaking significantly reduces the amount of lactose, or milk sugar, which is the main source of carbohydrates in dairy. Harder, aged cheeses generally have the lowest carb counts, as the aging process breaks down more of the lactose. However, not all cheeses are created equal. The key is to prioritize full-fat, minimally processed options while being mindful of portion sizes to stay within your daily macronutrient goals.

Benefits of Including Keto-Safe Cheeses

Beyond being a delicious addition to your meals, including the right types of cheese in your keto diet offers several benefits:

Flavor and Satiety: Full-flavored, high-fat cheeses add richness and complexity to dishes, helping to keep you feeling full and satisfied.
Essential Nutrients: Many cheeses are excellent sources of protein and calcium, supporting muscle maintenance and bone health.
Versatility: Cheese can be a versatile ingredient for snacks, toppings, or main dishes, making meal planning easier and more enjoyable.

Top Keto-Safe Cheeses to Enjoy

For the best results, focus on full-fat, natural cheese varieties. Here is a list of some of the most keto-friendly options:

Cheddar: One of the most popular keto cheeses, cheddar is low in carbs (less than 1g per ounce) and high in fat.
Parmesan: This hard, aged cheese is exceptionally low in carbohydrates, making it a perfect topping for salads or vegetables.
Goat Cheese (Chèvre): A creamy cheese with a tangy flavor, goat cheese is also low in lactose and carbs, often containing less than 1g of carbs per ounce.
Blue Cheese: Known for its distinct, pungent flavor, blue cheese varieties are high in fat with minimal carbs.
Cream Cheese: A keto staple for recipes, full-fat cream cheese is very low in carbs and high in fat.
Brie and Camembert: These soft, mild cheeses are very low in carbohydrates, perfect for pairing with nuts or low-carb crackers.
Mozzarella: A versatile cheese, mozzarella is great for melting on keto pizza or other dishes and has a very low carb count.
Swiss and Gruyère: Both offer a rich, nutty flavor and are excellent low-carb additions to your meals.

Cheeses to Consume in Moderation or Avoid

While most natural, full-fat cheeses are acceptable, some types should be limited or avoided due to their higher carb content or processing level.

Cheeses to Limit:

Cottage Cheese: While generally healthy and high in protein, cottage cheese has a higher carb count due to its lactose content. A half-cup serving contains approximately 5g of carbs, which can quickly add up for strict keto dieters.
Ricotta Cheese: Similar to cottage cheese, full-fat ricotta can be included in small amounts but should be portion-controlled due to its carb count.

Cheeses to Avoid:

Low-Fat and Nonfat Cheese: Removing fat from cheese often increases the carbohydrate content and can introduce additives. On a high-fat, low-carb diet, full-fat options are always preferred.
Processed Cheeses: Products like American cheese slices and spray-can cheese are highly processed, containing additives, fillers, and extra oils that are not beneficial for a keto lifestyle.
Pre-Shredded Cheeses: Some pre-packaged shredded cheeses contain added starches to prevent clumping. For the cleanest option, buy cheese in blocks and shred it yourself.
