Can I eat cheese and stay in ketosis? A deep dive

5 min read

According to research from the USDA, many natural cheeses contain less than 1 gram of carbohydrates per one-ounce serving, making them an ideal high-fat, low-carb food for those following a ketogenic diet. The key is knowing which types to choose and how to incorporate them without disrupting ketosis.

Quick Summary

Yes, you can eat cheese and stay in ketosis by selecting high-fat, low-carb varieties. Not all cheeses are created equal for the keto diet; hard, aged, and full-fat options are generally the best choice. Portion control and avoiding processed or high-lactose cheeses are critical to success.

Key Points

  • Carb Conscious Selection: To stay in ketosis, choose high-fat, low-carb cheese varieties, as carb content can differ significantly between types.

  • Aged is Better: Aged, hard cheeses like Parmesan and aged cheddar have very low carbohydrate levels due to the breakdown of lactose during the aging process.

  • Avoid Processed Cheeses: Steer clear of processed cheese products like American cheese singles and spray cheese, which contain added starches and fillers that increase the carb load.

  • Full-Fat Over Low-Fat: Always opt for full-fat versions of cheese, as low-fat or fat-free varieties often replace fat with higher-carb additives to improve flavor and texture.

  • Monitor Portion Sizes: While most cheese is keto-friendly, it is calorie-dense. Be mindful of portion sizes to avoid excessive calorie intake, which can hinder weight loss.

  • Read Labels Carefully: Always check the nutritional label for hidden carbs, especially on pre-shredded or softer cheeses, which can sometimes have higher carb counts due to added starches or lactose.

  • Digestive Sensitivity: If you have a dairy sensitivity or lactose intolerance, opt for aged, hard cheeses or goat cheese, which are naturally lower in lactose.

  • Incorporate Creatively: Use cheese to enhance meals with flavor and fat content, such as by making cheese crisps, adding to salads, or melting into sauces.

Navigating Cheese on Your Ketogenic Journey

For many, cheese is a comforting and versatile food, and the good news for keto dieters is that it's not off the table. The ketogenic diet's primary goal is to shift the body into a state of ketosis, where it burns fat for energy instead of glucose from carbohydrates. To achieve this, a dieter must adhere to a very low-carb, high-fat, and moderate-protein intake. This is where cheese, a naturally high-fat food, becomes a valuable tool.

The Science Behind Cheese and Ketosis

To understand why most cheeses are keto-friendly, it helps to know how they are made. During the cheesemaking process, milk is fermented, and the bacteria consume much of the lactose, or milk sugar, which is a carbohydrate. The longer a cheese is aged, the more lactose is broken down, resulting in a lower carb count. This makes hard, aged cheeses particularly suitable for keto, while fresh cheeses with more moisture often have a slightly higher, though still manageable, carb content.

Keto-Friendly Cheeses: The Best Choices

When choosing cheese on keto, prioritize full-fat, unprocessed options. The fat content helps you feel satiated, which can be beneficial for managing appetite on a low-carb diet. Always check nutrition labels, as carb counts can vary between brands, especially for softer cheeses.

  • Cheddar: A classic and versatile option, cheddar is a staple in many keto kitchens. One ounce of cheddar provides less than 1g of carbs and a good amount of fat and protein.
  • Goat Cheese (Chevre): With a tangy flavor and creamy texture, goat cheese is very low in carbs and a great addition to salads and appetizers. It also tends to be easier to digest for those with lactose sensitivity.
  • Blue Cheese: This flavorful cheese is low in carbs and offers a rich, creamy texture. Its strong taste means a little goes a long way, helping to control calorie intake.
  • Brie and Camembert: These soft, creamy cheeses have minimal carbs and can add a touch of indulgence to your meals. Pair them with keto-friendly crackers or nuts for a satisfying snack.
  • Cream Cheese: A favorite for many keto dessert and savory recipes, full-fat cream cheese is high in fat and low in carbs, making it a perfect keto staple.
  • Parmesan: This hard, aged cheese is known for its low carb content and nutty flavor. It can be grated over dishes or baked into cheese crisps.
  • Mozzarella: A low-carb, high-fat choice, mozzarella is excellent for melting on keto-friendly pizzas or incorporating into casseroles.

Cheeses to Limit or Avoid on Keto

Not all cheese is created equal for the keto diet. Some types contain more carbs due to higher lactose content or added ingredients. Moderation or avoidance is advised for these options.

  • Low-fat or Fat-free Cheeses: These versions often have a higher carb content to compensate for the flavor and texture lost from removing fat. Always opt for full-fat cheeses to align with keto's macro goals.
  • Processed Cheese: Products like American cheese singles, canned cheese, or spray cheese are heavily processed and contain additives, fillers, and extra carbs that offer little nutritional value. These should be avoided.
  • Cottage Cheese: While high in protein, cottage cheese has a higher carb count than many other cheeses due to its whey content. For strict keto, it's best to limit or avoid it, opting for full-fat versions if you do indulge in small amounts.
  • Ricotta: Similar to cottage cheese, full-fat ricotta can be included in small, controlled portions but has a higher carb count than other hard or soft cheeses.

Incorporating Cheese into Your Keto Meal Plan

Incorporating cheese can make your keto diet more satisfying and flavorful. Consider making your own keto-friendly snacks, such as cheese crisps made by baking small mounds of parmesan or cheddar until golden brown. You can also use cheese to create rich, creamy sauces for vegetables like broccoli or cauliflower. For a quick meal, pair slices of a hard cheese with olives, nuts, and keto-friendly cured meats. The richness of cheese helps with satiety, which can prevent you from overeating other foods.
