The Science Behind Low-Carb Cheese
When milk is made into cheese, enzymes and bacteria are used to curdle the milk, separating it into solid curds and liquid whey. A significant amount of the lactose, the primary carbohydrate in milk, is drained away with the whey. For aged cheeses, the remaining lactose continues to break down over time, resulting in an even lower carbohydrate count. This process makes most hard and aged cheeses the lowest in carbs, often containing less than 1 gram per serving.
Best Hard and Aged Cheeses (Minimal Carbs)
Hard and aged cheeses are superstars in the low-carb world due to their nearly non-existent carb content. They also pack a flavor punch, meaning a little goes a long way.
Parmesan (Parmigiano-Reggiano)
This aged cheese is a top contender, with some brands boasting zero carbs per serving. Its rich, nutty flavor is perfect for grating over salads, zoodles, or using to make homemade keto crisps.
Cheddar
One of the most popular and versatile low-carb cheeses is cheddar. An ounce of aged cheddar typically has less than 1 gram of carbohydrates and is a fantastic source of fat and protein. It works well in omelets, sauces, or as a standalone snack. Opt for full-fat, natural versions over processed cheddar products, which can contain added carbs.
Gruyère and Swiss
These alpine-style cheeses are also very low in carbs and known for their nutty flavor and superior melting qualities. They are excellent for rich, low-carb sauces, fondue, or adding to burgers. Swiss is also often recommended for those watching sodium intake, as it is lower than many other hard cheeses.
Excellent Soft and Semi-Soft Cheeses
Don’t overlook softer cheeses. Many are also low in carbs and can provide creamy texture to your meals and snacks.
Brie and Camembert
These creamy French cheeses have a buttery, rich flavor and a very low carb count, often around 0.1 grams per ounce. They are delicious baked, paired with nuts, or spread on keto-friendly crackers.
Goat Cheese (Chèvre)
Goat cheese is naturally low in carbs and has a distinct tangy flavor that works well in salads, omelets, and sauces. It is also lower in lactose than many cow's milk cheeses, which some people may find easier to digest.
Cream Cheese
Plain, full-fat cream cheese is a staple on many low-carb and keto diets. It adds a creamy texture to sauces, desserts, and dips, with a typical 2-tablespoon serving containing only about 1.6 grams of carbohydrates.
Cheeses to Approach with Caution
While most natural cheeses are low-carb, some varieties and processed products are not ideal for strict low-carb diets.
Cottage Cheese and Ricotta
These fresh cheeses have not had their lactose as completely removed, giving them a higher carb count than aged varieties. While still healthy and protein-rich, they should be consumed in moderation on a strict ketogenic plan.
Processed Cheese Slices and Spreads
American cheese singles and other processed cheese products often contain additives, starches, and preservatives that increase their carbohydrate content. It is best to avoid these and stick to natural, full-fat options.
Low-Fat or Reduced-Fat Cheese
In many low-fat cheeses, the fat is replaced with fillers and other ingredients that can increase the carbohydrate count. For low-carb diets that prioritize fat for energy, full-fat versions are always the better choice.
