Unlocking Muscle Gains: Why Do Body Builders Eat Cheese?

5 min read

According to a 2022 study in the Journal of Nutrition, consuming cheese after a resistance exercise session increased muscle protein synthesis rates in healthy, young males. This scientific finding helps explain why many dedicated body builders eat cheese, integrating this versatile dairy product into their nutritional strategy for muscle growth and recovery.

Quick Summary

Bodybuilders eat cheese for its high-quality protein, including slow-digesting casein for overnight repair and muscle growth, plus essential micronutrients like calcium and beneficial fats.

Key Points

  • Slow-Digesting Casein: Cheese is rich in casein protein, which digests slowly, providing a sustained release of amino acids for muscle repair, especially overnight.

  • High-Quality Complete Protein: Cheese offers a complete protein source containing all essential amino acids needed for muscle growth.

  • Rich in Calcium: Essential for strong bones and proper muscle function, cheese is a significant source of calcium.

  • Source of Healthy Fats and CLA: Some cheeses, particularly from grass-fed milk, contain beneficial fats like conjugated linoleic acid (CLA) that support lean muscle mass and fat loss.

  • Versatility in Diet: Different types of cheese can be used strategically for bulking (calorie-dense options) or cutting (lower-fat varieties like cottage cheese).

  • Micronutrient Benefits: Cheese provides important B vitamins (especially B12) and other minerals crucial for energy metabolism and overall health.

Beyond its satisfying taste, cheese holds a strategic place in a bodybuilder's diet due to its rich nutritional profile and the specific types of protein it contains. Unlike a simple, fast-absorbing protein shake, certain cheeses offer a slow-release protein source that fuels muscles over several hours, making it an ideal choice for specific meal timings. By understanding the nutritional nuances of different cheese varieties, bodybuilders can effectively utilize them to support their training and recovery goals, whether bulking or cutting.

The Power of Protein: Casein and Whey

The primary reason for cheese's popularity among bodybuilders is its exceptional protein content. Dairy products contain two main types of protein: whey and casein. While whey protein is known for its fast digestion and rapid amino acid delivery, making it ideal for a post-workout shake, casein is a slow-digesting protein that forms a gel-like clot in the stomach. This difference in absorption speed is key to its strategic application in bodybuilding nutrition.

Casein: The Overnight Muscle Builder

The slow digestion of casein protein is arguably its most prized attribute for bodybuilders. By providing a sustained release of amino acids into the bloodstream over several hours, it helps prevent muscle protein breakdown, also known as catabolism, during prolonged fasting periods like sleep. This makes a casein-rich food like cottage cheese a popular choice for a pre-bedtime snack. While you rest, casein works to continuously supply your muscles with the amino acids necessary for repair and growth. One cup of low-fat cottage cheese, for example, can contain around 24 grams of protein, predominantly casein.

Whey: The Rapid Recovery Partner

Although casein is the dominant protein, cheese also contains some whey protein. For instance, ricotta cheese is a byproduct of cheesemaking and is particularly rich in whey protein, offering a source for rapid muscle protein synthesis. While not as concentrated as a whey supplement, its presence in some cheese varieties contributes to the overall anabolic effect, helping kickstart the recovery process.

More Than Just Protein: A Micronutrient Powerhouse

Beyond protein, cheese provides several other vital nutrients essential for a bodybuilder's physique and overall health.

Calcium for Bone Strength

Building muscle requires a strong skeletal foundation, and cheese is an excellent source of bone-building calcium. Regular, high-impact resistance training places significant stress on bones, so maintaining strong bone density is crucial for preventing injuries. Consuming calcium from dairy, along with other nutrients, supports long-term bone health.

Essential Fats and CLA

Healthy fats are a cornerstone of any balanced diet, and certain cheeses, especially those from grass-fed sources, are a good source. These cheeses contain higher levels of conjugated linoleic acid (CLA), a fatty acid that has been linked to increasing lean muscle mass and decreasing body fat. While moderation is key due to the saturated fat content, particularly in full-fat varieties, incorporating healthy fats is important for hormone production and general wellness.

B Vitamins for Energy Production

Many types of cheese are rich in B vitamins, particularly B12. B vitamins play a critical role in energy metabolism, helping your body convert food into the fuel needed for intense workouts and daily activity. Swiss cheese, for example, is notably high in B12.

The Strategic Use of Cheese in a Bodybuilding Diet

How and when a bodybuilder consumes cheese is as important as the cheese itself. The strategy will differ depending on whether the goal is to bulk up or to shed fat.

Bulking vs. Cutting: Choosing Your Cheese

Different types of cheese offer different nutritional profiles. For a bulking phase, bodybuilders may opt for higher-fat, calorie-dense cheeses, while the cutting phase necessitates lean, low-fat options to manage caloric intake.

Feature Low-Fat Cottage Cheese Part-Skim Mozzarella Aged Parmesan Full-Fat Cheddar
Protein per 100g 11–14g 22.2g 35g ~25g
Fat per 100g 1–5g <10g ~25g ~33g
Calories per 100g ~80–120 kcal ~250 kcal ~420 kcal ~400 kcal
Primary Use Pre-bedtime snack, slow release Post-workout, lean protein Flavor enhancer, protein boost Bulking, calorie dense
Nutrient Focus Casein, low fat Protein, calcium Protein, calcium Calories, fat

Creative Ways to Incorporate Cheese into Your Diet

Cheese can be much more than just a slice. Here are a few creative and beneficial ways bodybuilders can add cheese to their meals, based on suggestions from fitness and nutrition sources:

  • Blend into smoothies: Add cottage cheese to morning smoothies for a protein boost and creamy texture.
  • Top salads and bowls: Sprinkle feta or goat cheese over salads and lean protein bowls for added flavor and nutrients.
  • Use as a healthy spread: Mix cottage cheese with salsa for a high-protein dip or spread it on whole-wheat toast.
  • Stuffed chicken or fish: Create flavorful fillings for chicken breasts or fish fillets using ricotta mixed with spinach and herbs.
  • Mix into eggs: Scramble eggs with a sprinkle of low-fat cheese for a protein-rich breakfast.
  • Make high-protein pasta: Stir cottage cheese into pasta dishes for a healthier, higher-protein version of a creamy sauce.

Potential Downsides and How to Manage Them

While cheese offers clear benefits, it's not without potential drawbacks. Many cheeses are high in saturated fat and calories, which can contribute to unwanted weight gain if not portion-controlled, especially during a cutting phase. Some varieties are also high in sodium, which is a concern for athletes monitoring blood pressure or managing hydration levels. Portion control is crucial, and opting for reduced-fat or lower-sodium versions can help mitigate these risks. For those with lactose intolerance, fresh cheeses like cottage cheese may cause digestive discomfort, while harder, aged cheeses have lower lactose content and might be better tolerated.

Conclusion: Cheese as a Strategic Tool

Bodybuilders do not eat cheese indiscriminately but rather use it as a strategic and nutrient-dense component of their diet. The inclusion of high-quality, natural cheeses—especially casein-rich varieties like cottage cheese—provides a slow and steady stream of amino acids for muscle repair and growth, which is particularly beneficial during rest and recovery periods. While managing the saturated fat and sodium content is necessary, the overall nutritional package of protein, calcium, and healthy fats makes cheese a powerful tool for achieving physique goals when consumed in moderation and as part of a well-balanced diet. It adds flavor and satiety, ensuring bodybuilders can stick to their nutritional plan and enjoy their meals without compromise.
