Greek Yogurt Protein: How Much Per Cup, vs Regular Yogurt & Best Brands
A 170g (6 oz) container of plain nonfat Greek yogurt has about 17 grams of protein and 124 calories. That is more than double the protein of regular yogurt per serving in the comparison below. In the USDA entries here, whole-milk versions carry more calories and less protein per 100g (exact values vary by brand). Plain is the safer default — flavored versions vary, and added sugar brings calories without any extra protein.

Brand labels vary slightly — some brands add milk protein concentrate to boost greek yogurt protein even higher, while others keep it minimal.
Why Greek Yogurt Has More Protein
Greek yogurt is regular yogurt that has been strained to remove most of the whey, the watery liquid. Straining removes water and some lactose, so everything left behind gets concentrated. That is the whole trick: the same milk makes yogurt with roughly double the protein per spoonful once the whey is drained off.
Traditional straining gives the thick texture and the tangy bite. Some brands skip real straining and instead add thickeners (starches, gums) plus extra protein powder — not automatically inferior, but it changes the profile. Traditionally strained yogurt lists milk and live cultures as the ingredients; a long ingredient list usually means a different product than the classic strained kind.
Greek Yogurt vs Regular Yogurt (per 170g)
Greek vs regular protein is no contest: Greek yogurt has roughly double the protein of regular yogurt per spoonful.
| Greek yogurt, nonfat | Regular yogurt, nonfat | Greek yogurt, whole milk | |
|---|---|---|---|
| Calories | 124 kcal | 95 kcal | 165 kcal |
| Protein | 17.3g | 7.3g | 9.0g |
| Carbs | 6.6g | 16.3g | 6.1g |
| Fat | 0.7g | 0.5g | 8.5g |
| Calcium | 187mg | 205mg | 170mg |
Greek yogurt protein wins by a wide margin: more than double the protein of regular yogurt in the same container. Regular yogurt keeps more carbs (lactose) and a bit more calcium, but for protein goals, Greek is the clear pick.
Nonfat vs Lowfat vs Whole Milk Greek Yogurt
Fat level changes the greek yogurt protein math in both directions:
- Nonfat (0%): highest protein per calorie, ~17g protein for 124 calories per 170g. Often the best fit when protein per calorie is the priority.
- Lowfat (2%): a middle ground, ~14g protein and ~150 calories per 170g. Better taste, still lean.
- Whole milk (~5%): richer and creamier, ~9g protein and ~165 calories per 170g. Useful for adding calories, or if you find nonfat chalky.
Pick nonfat when protein per calorie is the priority; pick whole milk when you want the calories or the taste keeps you consistent. Consistency beats the perfect label.
Greek Yogurt Protein by Brand (170g, plain)
Protein varies by brand because straining time and milk protein additions differ. Approximate values per 170g container of plain nonfat (from current brand labels — they differ from the generic USDA entry above, so check your tub):
| Brand | Protein | Calories |
|---|---|---|
| Fage Total 0% | 18g | 90 kcal |
| Chobani Non-Fat Plain | 16g | 90 kcal |
| Oikos 0% | 18g | 100 kcal |
| Stonyfield Organic 0% | 15g | 90 kcal |
Flavored versions of these same brands typically add 12-19g of sugar and keep the protein roughly the same, which is why plain plus your own fruit is the better default. Labels change, so check the panel on your exact tub.
Probiotics and Gut Health
Real Greek yogurt contains live active cultures (typically L. bulgaricus and S. thermophilus, often plus added probiotic strains). Yogurt cultures help ferment the lactose, and live-culture yogurt may be easier to digest for some people — but strains and amounts vary by product, and live cultures alone do not guarantee a specific gut or immune benefit (Harvard T.H. Chan School of Public Health notes yogurt as a fermented food worth including regularly).
One catch: heat treatment after culturing can reduce or eliminate live cultures. Look for the “Live & Active Cultures” seal or the words “contains live cultures” on the label.
The Flavored Yogurt Sugar Trap
Some 170g flavored Greek yogurt cups pack 15-20g of added sugar while keeping the same protein as plain (others add much less — check the label). The greek yogurt protein you came for is still there, but you may be paying for it with dessert-level sugar.
The fix takes ten seconds: buy plain and add your own toppings. A handful of berries adds fiber and real flavor for roughly 40 calories (varies by berry and portion). A drizzle of honey (1 tsp) adds 21 calories and keeps the total sugar honest. You control the sweetness; the brand does not.
Buying and Storage Tips
- Ingredients first: The shortest list wins, milk and live active cultures. Skip thickeners and added protein concentrates if you want traditionally strained yogurt.
- Check the protein per 100g: Nonfat should be near 10g per 100g. If it is 4-5g, it is far below the strained standard in this table — compare labels rather than trusting the front of the tub.
- Storage: Keep refrigerated and follow the date and storage guidance on your tub. Once opened, eat within about 5-7 days. You can freeze it, but the texture turns grainy after thawing — best used in smoothies or cooking.
- That liquid on top: It is whey, not spoilage. Stir it back in (it holds protein and calcium) or pour it off for thicker yogurt.
Greek Yogurt, By Goal
For Weight Loss
Greek yogurt is one of the most useful weight-loss foods in the dairy aisle. Seventeen grams of greek yogurt protein for 124 calories is an excellent protein-per-calorie ratio, and thick strained yogurt can be genuinely filling — some studies link high-protein breakfasts to less snacking later in the day, though results vary. Use a 170g nonfat container with berries as a ~180-calorie breakfast or snack that can keep you going for a good stretch (fullness varies by person). The only rule: buy plain. Flavored cups often carry notably more calories from added sugar, without adding fullness.
For Weight Gain
Whole-milk Greek yogurt is a handy weight-gain option (nonfat can work too, with calorie-dense toppings). A 170g container delivers ~165 calories plus 9g of protein, and it blends into everything calorie-dense: smoothies with peanut butter and banana, parfaits layered with granola and honey, or savory bowls with olive oil and nuts. Two servings a day add ~330 calories and 18g of protein without much chewing, useful when eating more feels like work. Pair with the calorie calculator to set your daily target.
For Muscle Building
Greek yogurt earns its place in a muscle-building diet on protein density and casein content. Much of its protein is casein, which digests slowly — one reason a pre-bed serving is popular with lifters — though total daily protein matters far more than timing. A 250g bowl of nonfat Greek yogurt gives ~25g of complete protein, including leucine, for about 180 calories. Stack it after training with fruit and honey for fast carbs plus slow protein, or mix a scoop of whey into it for a 45g-protein snack.
Frequently Asked Questions
How much protein is in one cup of Greek yogurt?
One cup (245g) of plain nonfat Greek yogurt has about 25g of protein and 180 calories. Whole-milk Greek yogurt has about 13g of protein and 238 calories per cup.
Is the greek yogurt protein really double that of regular yogurt?
Roughly, yes. Per 170g, nonfat Greek yogurt has ~17g of protein versus ~7g in regular nonfat yogurt. Straining out the whey concentrates the protein, which is most of the difference (formulations vary).
Which Greek yogurt brand has the most protein?
Strained brands like Fage Total 0% lead at ~18g per 170g container. Most major plain nonfat brands land between 14-18g. Always check your specific tub, recipes change.
Is Greek yogurt good for weight loss?
Yes, when it fits your calories. High greek yogurt protein with low calories can be very filling, and some studies link high-protein breakfasts to less snacking later (results vary). Stick to plain nonfat and add your own fruit.
Can I eat Greek yogurt every day?
For most people, yes, it is a solid daily protein and calcium source with probiotics. If you have trouble with lactose, Greek yogurt is often easier to tolerate: straining and fermentation reduce much (not all) of the lactose, though amounts vary by product — try a small amount first, and lactose-free versions exist.
Does Greek yogurt have a lot of sugar?
Plain Greek yogurt has ~4g of natural milk sugar per 100g and zero added sugar. Flavored versions may add 15-20g of sugar per container (others add less or none) — plain has only the natural milk sugar, which is where the difference lives.
Is Greek yogurt a complete protein?
Yes. It contains all nine essential amino acids, so it counts as a complete protein source for muscle building and daily needs.
Greek yogurt protein is hard to beat for the calories — strained, plain, and checked against your own tub’s label.
