Cottage cheese vs Greek yogurt: which is the better protein?

Both are excellent, high protein, low sugar dairy foods, and you cannot go wrong with either. Plain nonfat Greek yogurt wins slightly on protein per calorie and per serving. But cottage cheese is often eaten in larger portions and is higher in slow-digesting casein, which makes it a strong pick too. The real winner is the one you will actually eat every day.

Key takeaways

• Greek yogurt has the highest protein percentage: 77% of calories in plain nonfat Greek yogurt come from protein.
• Nonfat cottage cheese is close behind at 69%, and it holds its protein even at higher fat levels.
• Greek yogurt offers probiotics and more calcium. Cottage cheese offers more casein and, usually, more sodium.
• Skip the flavored versions. Added sugar and fruit drag the protein percentage down fast.
• Both fit low carb, keto, weight loss, and muscle-building goals.

 

Why this matchup matters right now

High protein dairy is having a moment. Cottage cheese, once a diet food from another era, roared back thanks to social media. US retail sales jumped 20% in the year to June 2025, on top of roughly 17% gains in both 2023 and 2024, according to market research firm Circana. Greek yogurt has been a grocery staple for a decade. Shoppers are reading labels for protein like never before, with one 2026 report finding that 80% of consumers now pay attention to it.

So the question is fair: if you have room for one tub in your cart, which delivers more? Let us settle it with numbers, not hype.

Round 1: protein per calorie

At Diet Doctor, we rank protein foods by protein percentage, which tells you how many of a food’s calories come from protein rather than fat or carbs. The higher the number, the more protein you get per calorie. For weight loss, we look for foods at 35% or higher. Both of these foods clear that bar easily.

Here is how the plain versions stack up.

Greek yogurt and skyr (per 5-ounce, 170-gram serving, about three-quarters of a cup)

Type	Protein %	Protein	Carbs
Plain nonfat (0%)	77%	18 grams	5 grams
Plain low-fat (2%)	57%	17 grams	5 grams
Plain full-fat (5%)	38%	16 grams	5 grams
Plain triple cream (9%)	23%	14 grams	8 grams

Cottage cheese (per 4-ounce, 113-gram serving, about one-half cup)

Type	Protein %	Protein	Carbs
Nonfat (0%)	69%	13 grams	5 grams
Low-fat (1%)	65%	13 grams	5 grams
Low-fat (2%)	58%	13 grams	5 grams
Regular (4%)	47%	13 grams	5 grams
With pineapple	31%	10 grams	15 grams

Winner: Greek yogurt, by a nose. Plain nonfat Greek yogurt hits 77%, the highest of any everyday dairy food. Nonfat cottage cheese follows at 69%. Both are outstanding, and both beat most cheeses and all milks. Nutrition values come from the USDA database and can vary a little by brand, so it always pays to read the label. ¹

One cottage cheese advantage stands out: it keeps a high protein percentage even in its fattier forms. Regular 4% cottage cheese still delivers 47% protein. Full-fat 5% Greek yogurt drops to 38%. So if you prefer the taste of full-fat dairy, cottage cheese holds its protein better.

Round 2: protein per serving

Protein percentage is only half the story. What lands on your plate matters too, and this is where portion size flips the picture.

The numbers above use standard servings, and they are not the same size. A typical Greek yogurt serving is 5 ounces, while a cottage cheese serving is 4 ounces. That is part of why the yogurt shows more grams.

In the real world, people rarely stop at a half cup of cottage cheese. A full cup of cottage cheese runs closer to 24 to 28 grams of protein, which matches or beats a full cup of Greek yogurt. So how you eat it changes the answer.

Winner: a tie, depending on your bowl. Gram for gram at equal weight, they are neck and neck. Greek yogurt edges ahead per calorie, cottage cheese catches up when you eat a bigger scoop. Either one can deliver 25 to 30 grams of protein in a single serving, which is a full meal’s worth for many people. Not sure how much you need? See our guide on how much protein you need per day.

Round 3: carbs and sugar

Plain versions of both foods are naturally low in carbs, around 5 grams per serving. The trouble starts with the flavored tubs.

Fruit-on-the-bottom yogurt and sweetened cottage cheese can carry as much sugar as dessert. Sugar-sweetened nonfat yogurt jumps to 32 grams of carbs per serving, and cottage cheese with pineapple lands at 15 grams. Both moves crush the protein percentage.

The fix is simple: buy plain, then add your own flavor. Berries, cinnamon, vanilla, or a sugar-free sweetener give you taste without the sugar hit. For a savory spin, cottage cheese shines with black pepper, herbs, or everything-bagel seasoning.

Winner: a tie, as long as you choose plain.

Round 4: the extras that set them apart

Protein is the headline, but a few other differences may decide your pick.

Probiotics. Yogurt is fermented with live bacterial cultures, which support gut health. Most cottage cheese is not fermented and lacks these cultures, unless the label specifically says it contains live cultures. Edge: Greek yogurt.

Calcium. Straining and draining remove some calcium from cottage cheese along with the whey. Greek yogurt usually delivers more calcium per serving. This matters for bone health. In a two-year trial of more than 7,000 older adults in residential care, adding extra milk, yogurt, and cheese cut all fractures by 33% and hip fractures by 46%. ² Edge: Greek yogurt.

Sodium. Cottage cheese is often much saltier, commonly 300 milligrams of sodium or more per half cup, while plain Greek yogurt is usually low, often under 70 milligrams. That is a gap of nearly 9 to 1 by some measures. If you watch your salt, look for a no-salt-added or reduced-sodium cottage cheese. Edge: Greek yogurt.

Casein for slow digestion. Cottage cheese is rich in casein, a protein your body breaks down slowly. That steady release is why many people enjoy it as a nighttime snack to feed muscles overnight. Greek yogurt contains casein too, plus a little more whey. Edge: cottage cheese.

Satiety. Both are among the most filling foods you can eat, because protein tames appetite better than fat or carbs. ³ This is the heart of higher-satiety eating. Edge: a tie.

Which should you choose for your goal?

For weight loss: Reach for the highest protein percentage. Plain nonfat Greek yogurt at 77% is the leanest, most filling choice per calorie. Higher protein diets reliably beat lower protein diets for fat loss on the same calories. ⁴

For building or keeping muscle: Both work, and eating enough total protein matters more than the source. Cottage cheese before bed is a classic move for its slow-digesting casein. In older adults, higher protein intake helps preserve lean mass during weight loss. ⁵

For keto or very low carb: Both fit at roughly 5 grams of carbs per plain serving. Choose full-fat cottage cheese if you want more fat with your protein, since it holds a higher protein percentage than full-fat yogurt.

For gut health: Greek yogurt, thanks to its live cultures.

How to eat more of both

Frequently asked questions

Which has more protein, cottage cheese or Greek yogurt? 

Per calorie, plain nonfat Greek yogurt wins at 77% protein versus 69% for nonfat cottage cheese. Per equal weight they are very close, and a large scoop of cottage cheese can pull ahead in total grams.

Is cottage cheese or Greek yogurt better for weight loss? 

Plain nonfat Greek yogurt has the highest protein percentage, so it gives the most protein per calorie. That said, both are excellent, filling, low sugar choices that support fat loss.

Which is better before bed? 

Cottage cheese is the traditional nighttime pick because it is high in casein, a slow-digesting protein that feeds your muscles through the night. Greek yogurt works well too.

Are cottage cheese and Greek yogurt keto? 

Yes. Plain versions have only about 5 grams of carbs per serving. Choose full-fat cottage cheese for more fat, and always avoid the sweetened, fruit-added tubs.

Which has more sugar? 

Plain versions are similar and low. The difference comes from flavoring. Sweetened yogurt and fruit-added cottage cheese can carry two to six times the carbs of the plain versions, so buy plain and flavor it yourself.
