How much protein is in Greek yogurt?
USDA FoodData Central lists nutrients per 100 grams. The 170-gram column below multiplies those figures out, because 170 grams is the reference amount listed for yogurt in these USDA entries, about the size of a single-serve cup. Numbers are rounded.
Yogurt (plain, unflavored) | Protein per 100 g | Protein per 170 g | Calcium per 100 g |
|---|---|---|---|
Greek, nonfat | 10.3 g | about 17.5 g | 111 mg |
Greek, whole milk | 8.8 g | about 14.9 g | 111 mg |
Regular, nonfat | 4.2 g | about 7.2 g | 167 mg |
Regular, whole milk | 3.8 g | about 6.5 g | 127 mg |
Two things stand out. First, Greek yogurt carries about twice the protein of regular yogurt, whether you compare nonfat to nonfat or whole milk to whole milk. Second, regular yogurt has more calcium per 100 grams in these USDA entries. Neither is "better" across the board. They're good at different things.
Brands vary, so check the Nutrition Facts label on the cup you buy. The label shows protein per serving, and the serving size may not match 170 grams.
Nonfat, low-fat or full-fat?
The protein difference between nonfat and whole-milk Greek yogurt is small, about 1.5 grams per 100 grams in the USDA data. The bigger difference is fat and calories.
The 2025–2030 Dietary Guidelines for Americans say that when you eat dairy, you can include full-fat dairy with no added sugars, and they count whole, reduced-fat, low-fat and nonfat yogurt in the dairy group. In other words, pick the fat level that fits your overall eating pattern and keeps you satisfied. Choose plain over sweetened at any fat level.
The added sugar check
Flavored Greek yogurt can carry a lot more sugar than plain. In USDA's data, strawberry low-fat Greek yogurt has about 11.2 grams of total sugars per 100 grams, compared with about 3.3 grams in plain nonfat Greek yogurt. Plain yogurt's sugar comes from the milk itself.
Here's how to read the label:
- Look at "Includes Xg Added Sugars." FDA explains that this line tells you how much of the total sugar was added during processing. Sugar naturally found in milk isn't counted as added.
- Use the %DV. FDA says 5% Daily Value or less is low and 20% or more is high.
- Check the ingredients. The Dietary Guidelines suggest looking for words like "sugar" or "syrup," or words ending in "-ose."
- Know the yogurt benchmark. The 2025–2030 Dietary Guidelines say dairy snacks such as yogurt should not exceed 2.5 grams of added sugar per ⅔ cup.
The easiest fix is to buy plain and add your own sweetness: fresh or frozen berries, sliced banana, or a little cinnamon.
How Greek yogurt fits into your day
The 2025–2030 Dietary Guidelines count ¾ cup of yogurt as one serving of dairy and set a goal of 3 dairy servings a day for a 2,000-calorie pattern. For protein, they set a goal of 1.2 to 1.6 grams per kilogram of body weight a day, adjusted to your calorie needs, and they encourage protein foods at every meal.
A cup of Greek yogurt won't cover your protein for the day, but it's an easy, no-cook way to add a solid amount to a meal that might otherwise be light on protein, like breakfast or a snack.
12 easy ways to use Greek yogurt
Breakfast
- Yogurt bowl. Plain Greek yogurt, berries, a spoon of nuts or seeds, and a sprinkle of oats.
- Overnight oats. Stir yogurt into oats with milk and fruit the night before.
- Smoothie base. Blend yogurt with frozen fruit and a handful of spinach.
- Pancake or waffle topping. Use it in place of syrup-heavy toppings, with fruit on top.
Lunch and dinner
- Sour cream swap. Top tacos, chili, baked potatoes or soup.
- Lighter "mayo" salads. Use half yogurt, half mayo in chicken, tuna or egg salad.
- Creamy dressing. Whisk yogurt with lemon juice, garlic, herbs, salt and pepper.
- Marinade. Coat chicken in yogurt, lemon and spices before baking or grilling.
- Cucumber yogurt sauce. Grated cucumber, garlic, dill and lemon for grain bowls and wraps.
Snacks and dessert
- Veggie dip. Mix yogurt with a ranch-style herb blend for raw vegetables.
- Frozen yogurt bark. Spread yogurt on a lined tray, top with berries, freeze and break into pieces.
- Parfait. Layer yogurt, fruit and a few crunchy nuts in a jar for a grab-and-go snack.
Storing and buying tips
- Keep yogurt in the refrigerator and close the lid between uses.
- A large tub of plain yogurt usually goes further than single-serve cups. Portion it into containers for the week.
- If you don't eat dairy, compare plant-based yogurts carefully. In USDA's data, a plain soy yogurt has much less protein than plain Greek yogurt, so check the label.
Use cases: practical scenarios
- "I skip breakfast because I'm never hungry." A small yogurt bowl is quick and doesn't need cooking.
- "I'm trying to get more protein without cooking more." Use yogurt as a sauce, dip or topping on foods you already eat.
- "My kids like the flavored cups." Mix half plain and half flavored, and lower the share of flavored over time.
- "I'm on a GLP-1 and eating less." Small, protein-rich foods like Greek yogurt are easy to fit in. See our guide to eating clean on Wegovy.
- "I snack at night." A planned yogurt parfait can replace an unplanned trip to the pantry. Our guide to food noise has more ideas.
Frequently asked questions
How much protein is in a cup of Greek yogurt?
USDA FoodData Central lists about 10.3 grams of protein per 100 grams of plain nonfat Greek yogurt. A 170-gram (6-ounce) cup works out to about 17.5 grams. Whole-milk Greek yogurt has about 8.8 grams per 100 grams. Check your brand's label, because products vary.
Does Greek yogurt have more protein than regular yogurt?
Yes. In USDA data, plain Greek yogurt has roughly twice the protein of plain regular yogurt at the same fat level: about 10.3 versus 4.2 grams per 100 grams for nonfat. Regular yogurt has more calcium per 100 grams.
Is nonfat or full-fat Greek yogurt better?
The protein is similar. Nonfat has about 10.3 grams per 100 grams and whole milk about 8.8 grams, per USDA. The 2025–2030 Dietary Guidelines allow full-fat dairy with no added sugars, so choose the one that fits your eating pattern and keeps you full.
How do I know if my yogurt has too much added sugar?
Read the "Includes Xg Added Sugars" line on the Nutrition Facts label. FDA says 5% Daily Value or less is low and 20% or more is high. The 2025–2030 Dietary Guidelines say yogurt snacks should not exceed 2.5 grams of added sugar per ⅔ cup.
Can I cook with Greek yogurt?
Yes. It works as a marinade, a sour cream swap, a creamy dressing and a dip. Add it to hot dishes at the end, off the heat, to keep the texture smooth.
Is Greek yogurt a good snack for weight loss?
It can help. Plain Greek yogurt is high in protein and low in added sugar, which makes it an easy snack to fit into a reduced-calorie eating pattern. Portions and toppings matter more than the yogurt itself.
