How much protein is in Greek yogurt?
Plain Greek yogurt typically provides about 9–10 grams of protein per 100 grams, or roughly 15–20 grams in a common single-serving container.
Quick answer
A 170–200 g serving of plain Greek yogurt usually contains 15–20 g of protein. Straining removes part of the liquid whey, which concentrates protein compared with regular yogurt.
| Yogurt | Protein per 100 g | Protein per serving |
|---|---|---|
| Greek yogurt | 9–10 g | 15–20 g per 170–200 g |
| Regular yogurt | 3–5 g | 6–10 g per 170–200 g |
| Skyr | 10–11 g | 17–22 g per 170–200 g |

Why Greek yogurt is higher in protein
Traditional Greek-style yogurt is strained after fermentation. Removing some liquid whey makes the yogurt thicker and concentrates protein and other solids. Some commercial products use different processing methods, so the nutrition label is the final authority.
Nonfat, low-fat and whole-milk Greek yogurt
Fat percentage changes calories and texture more than protein. Plain nonfat, low-fat and whole-milk Greek yogurts can all be protein-rich, although recipes and serving sizes differ.
| Type | Typical protein per 100 g | What changes most |
|---|---|---|
| Nonfat | 9–11 g | Lowest fat and usually fewer calories |
| Low-fat | 9–10 g | Middle ground for texture and calories |
| Whole-milk | 8–10 g | More fat and a creamier texture |
How to choose a high-protein yogurt
Compare products using the same serving size. A larger container can appear higher in protein even when the concentration is similar. For a protein-focused snack, look for about 15 g or more per serving and check added sugar separately.
- Check grams of protein per serving and per 100 g.
- Use added sugar as a separate comparison point.
- Choose a fat level that fits the rest of your meals.
- Remember that flavored toppings can change the final macros.
Greek yogurt as part of a meal
Greek yogurt works as a snack, breakfast base, dip or substitute for part of the cream in a recipe. Pairing it with fruit, oats, seeds or nuts adds carbohydrate, fiber and fat, turning a protein-rich ingredient into a more complete meal.
