Cheese for weight loss

Protein in cheese

Cheese made from dairy gives you complete protein, with all the essential amino acids your body needs. Dairy protein is mostly casein (about 80%) and whey (about 20%), the split Bendtsen and colleagues report.

According to a review in Advances in Nutrition, casein is a "slow" protein and whey is a "fast" one. Whey looks more filling in the short term and casein more filling in the long term. The same review found no clear evidence that one protein source did better than the others for body weight or body composition, and research on whether that fullness leads people to eat less later is mixed. So treat this as a small assist.

An ounce of many firm cheeses has about 7 grams of protein, Parmesan has about 10 and a half cup of 2% cottage cheese has about 12. When you're working toward your daily protein targets for weight loss, cheese can be a convenient contributor, as long as you count the calories that come along with it.

Cheese & fullness

The most relevant study is small but direct. In a 2018 crossover trial in the Journal of Nutritional Science, 39 normal-weight adults ate 80 grams of one of three cheeses at breakfast, then an all-you-want lunch 3 hours later. The high-protein, lower-fat cheese had the fewest calories, and total intake came out about 188 kJ lower, which is about 45 calories, than with the high-protein, high-fat cheese.

The difference against the low-protein, high-fat cheese wasn't statistically significant. What does hold up is that people didn't make up for the lower-calorie cheese by eating more at lunch. That's one meal in healthy adults, so read it as a reason to favor higher-protein cheese, and not as proof that cheese curbs appetite over months.

Using cheese as a substitution

Instead of cutting cheese completely, think about what it can replace in a meal. A small portion adds flavor, protein and fat, and it can stand in for other calorie sources while making the meal more satisfying. An ounce of feta on a salad, for example, can replace a heavy pour of creamy dressing. Two tablespoons of ranch is about 130 calories, compared with about 75 for that feta, and it brings much less protein.

Calorie density in cheese

Many cheeses have about 70 to 120 calories per ounce, so a small portion carries a real amount of energy. An ounce of cheddar is smaller than most people picture, about 2 to 3 stacked dice.

That's why casual snacking is the risk. Standing at the fridge with a block of cheddar, you can eat a few ounces without registering it as a meal. A little attention to portions keeps your intake close to what you meant to eat.

Cheese as an add-on

Cheese often lands on top of foods that already have plenty of calories, like pizza, burritos or pasta. In those cases, it's adding calories you didn't plan for. Think of it as a planned ingredient, not an automatic topping, and it gets a lot easier to keep it in a calorie-controlled diet.

Saturated fat & sodium in cheese

Cheese also brings saturated fat and sodium, which some people need to watch. Many full-fat cheeses have about 5 to 6 grams of saturated fat per ounce. MedlinePlus, citing the Dietary Guidelines for Americans, puts the limit at less than 10% of daily calories, which is 22 grams on a 2,000-calorie diet. Do the math and 2 ounces of cheddar, at about 11 grams, uses half of that. If you have high cholesterol, talk with your doctor about how much cheese makes sense for you.

Sodium is the other number. Feta and Parmesan have over 300 mg per ounce, and process American has about 470 mg. That can cause some temporary water retention, and it matters if you're managing your blood pressure. Swiss, at about 50 mg an ounce, is the easy low-sodium choice.

Reading cheese nutrition labels

• Serving size: Check this first. Cheese labels are often based on 1 ounce (28 g), but some list 1/4 cup shredded or another measure. Make sure the serving sizes match before you compare.
• Protein per calorie: See how much protein you get for the calories. Cottage cheese tends to give you more protein for fewer calories, while cream cheese gives you very little.
• Sodium: Levels vary across brands and types. If you're watching sodium, for example to manage your blood pressure, compare what's listed per serving.

Natural vs. processed cheese

Natural cheese is made from milk, cultures and enzymes. Processed cheese, like American singles and cheese spreads, adds emulsifiers, sodium phosphates and other ingredients. Processed cheese isn't automatically bad, but USDA's numbers show the tradeoff: an ounce of process American has about 470 mg of sodium and 5 grams of protein, compared with about 183 mg and 7 grams for sharp cheddar. If you prefer less processed foods, look for a shorter ingredient list.

Budget-friendly cheese options

Cheese prices vary widely by format and brand. Here's where you can usually save:

• Block cheese often costs less per ounce than the pre-shredded kind.
• Store brands may offer similar products at lower prices than national brands.
• Larger containers, especially cottage cheese, can be better value than single-serve cups.
• Some hard cheeses can be frozen, which helps cut waste when you buy larger amounts.

Lactose in cheese

Many aged cheeses, like cheddar, Swiss, Parmesan and Gouda, have relatively little lactose, because much of the milk sugar breaks down during aging. Some people with lactose intolerance find them easier to tolerate. Fresh cheeses, including cottage cheese, tend to have more lactose, though lactose-free versions exist. If dairy gives you ongoing symptoms, it's worth raising with your doctor.

Visual cheese portion guides

• 1 ounce of hard cheese: about 2 to 3 stacked dice, or a thin slice that covers a piece of toast.
• 1/4 cup of shredded cheese: about 1 ounce, roughly a golf ball.
• 1/2 cup of cottage cheese: one standard serving, about half a baseball.
• 1 tablespoon of cream cheese: about the size of your thumb.

These are rough guides, and different food guides use slightly different comparisons. A scale will always beat a mental picture.

Measuring & pre-portioning cheese

If you're not sure what a typical serving looks like, measure it now and then. A small food scale makes this quick, and over time many people get comfortable estimating by eye.

When you bring cheese home, divide it up. Cut a block of cheddar into 1-ounce pieces and store them individually. Spoon cottage cheese into 1/2-cup containers. It reduces the temptation to grab just a little more, and it makes tracking simple.

Cottage cheese breakfast bowl

About 235 calories, about 20 g protein.

Ingredients: 3/4 cup 2% cottage cheese, 1/2 cup mixed berries, 1 tablespoon slivered almonds, 1 teaspoon honey (optional)

Prep tip: Blend the cottage cheese briefly if you'd like a smoother, yogurt-like texture. If you need this to carry you to lunch, make it a full cup of cottage cheese. That adds about 45 calories and 6 grams of protein.

Mediterranean veggie salad with feta

About 450 calories, about 42 g protein.

Ingredients: 3 cups mixed greens, 4 ounces grilled chicken breast, 1 ounce crumbled feta, cucumber, tomatoes, a few olives, and 1 tablespoon olive oil with lemon juice

Prep tip: Feta adds creamy, tangy flavor, so you need less dressing. The oil is about a quarter of the calories here, so measure it. This pairs well with the ideas in our 15 High-Protein Meals Under 500 Calories guide.

Cheesy veggie omelette

About 340 calories, about 28 g protein.

Ingredients: 3 whole eggs, 1 ounce shredded Swiss cheese, 1 cup raw spinach and 1/2 cup raw mushrooms, sautéed, cooking spray

Prep tip: Cook the vegetables first, set them aside, then make the omelette. Swiss adds nutty flavor with very little sodium, which helps if you're watching salt.

Afternoon cheese snack plate

About 290 calories, about 10 g protein.

Ingredients: 1 ounce sharp cheddar, cubed, 1 small apple, sliced, and 5 whole grain crackers

Prep tip: The mix of protein, fiber and complex carbs makes this a satisfying snack, though at about 290 calories it's closer to a mini meal. Drop the crackers and you're at about 195. Check out our 29 Healthy Snacks for Weight Loss for more ideas.

Parmesan-crusted salmon dinner

About 430 calories, about 38 g protein.

Ingredients: 5-ounce salmon fillet, 2 tablespoons grated Parmesan, 1 teaspoon Dijon mustard, 1 cup roasted broccoli with 1 teaspoon olive oil

Prep tip: Mix the Parmesan with the mustard, spread it on the salmon and bake at 400°F for 12 to 15 minutes, until the salmon reaches 145°F. The Parmesan makes a flavorful crust with no breading.

High-flavor, low-calorie cheese ideas

• Use sharp or aged varieties. Extra-sharp cheddar and aged Parmesan have more flavor per ounce than milder cheeses, so a smaller portion can feel like enough. A tablespoon of grated Parmesan can add a noticeable hit to vegetables or pasta.
• Pair with bold flavors. Jalapeños, sun-dried tomatoes, olives and fresh herbs raise the flavor of a dish without adding more cheese.

Smart cheese swaps

• Blended cottage cheese can replace cream cheese in dips or spreads.
• Greek yogurt with a little feta gives you a similar tang on tacos or baked potatoes.
• Individually portioned cheeses, like Laughing Cow wedges, can help some people manage serving sizes.

These swaps follow the same idea as our Best Fats for Weight Loss guide: choose nutrient-dense options that fit your goals.

Refrigerating cheese

• Hard cheeses like cheddar, Parmesan and Swiss: Wrap tightly in plastic wrap or wax paper, then put in a plastic bag. They keep about 3 to 4 weeks after opening.
• Soft cheeses like Brie: Store in the original packaging or an airtight container. USDA says soft cheeses keep about a week in the refrigerator.
• Cottage cheese: Keep sealed, go by the date on the container and, once it's open, use it within about a week.
• Shredded cheese: Keep it in the original bag, squeeze out the air and seal it tightly. Use it within 5 to 7 days of opening, or by what the package says.

Freezing cheese

Most hard and semi-hard cheeses can be frozen for up to 3 to 6 months if you store them well. Wrap the cheese tightly in plastic wrap, then put it in aluminum foil or a sealed freezer bag to help prevent freezer burn. Thaw it in the refrigerator. Frozen cheese is often best in cooked dishes, since freezing can make it a little crumbly.

Don't freeze cottage cheese, cream cheese or ricotta. They don't handle it well and can turn watery when thawed.

Signs cheese has spoiled

• Visible mold, except on intentionally moldy cheeses like blue cheese
• A slimy texture or ammonia smell
• Significant changes in color
• A sour or off taste

Mold on a block of hard cheese doesn't always mean you have to toss the whole thing. UConn Extension, drawing on USDA guidance, says to cut at least an inch around and below the spot. Throw out soft cheese with mold on it. When in doubt, throw it out. No piece of cheese is worth a foodborne illness.
