How Many Calories in Greek Yogurt?
About 100 kcal per ¾ cup of plain nonfat. Flavored varieties land closer to 150–180.
Plain nonfat Greek yogurt is about 100 kcal per ¾ cup, with ~18 g protein. 2% Greek runs ~140 kcal; whole milk Greek is ~190. Flavored varieties add ~50 kcal of sugar. The protein-per-calorie ratio is one of the best in the dairy aisle — useful for breakfast, snacks, smoothies, and as a sour-cream substitute.
The Headline Numbers
Per ¾-cup (~170 g) serving:
| Type | Calories | Protein | Fat | Carbs |
|---|---|---|---|---|
| Plain nonfat Greek yogurt | 100 | 18 g | 0 g | 6 g |
| Plain 2% Greek yogurt | 140 | 17 g | 4 g | 6 g |
| Plain whole milk Greek yogurt | 190 | 16 g | 10 g | 6 g |
| Plain Icelandic skyr | 110 | 19 g | 0 g | 7 g |
| Vanilla Greek yogurt (sweetened) | 150 | 14 g | 0 g | 19 g |
| Strawberry Greek yogurt (fruit-on-bottom) | 160 | 13 g | 2 g | 21 g |
| Flavored “light” Greek (stevia-sweetened) | 90 | 14 g | 0 g | 5 g |
| Regular (non-Greek) plain yogurt | 105 | 9 g | 0 g | 12 g |
| Coconut “Greek” yogurt | 180 | 6 g | 14 g | 9 g |
Two takeaways:
- Greek vs regular is mostly a protein difference (~2× for Greek). Calories are similar; protein per calorie is much better for Greek.
- Flavored Greek sneaks in ~50 kcal of sugar per cup. Buy plain, sweeten yourself.
Container Sizes (Common Brands)
| Container | Plain Nonfat Calories |
|---|---|
| 5.3 oz cup (Chobani, Fage, etc.) | 80 |
| ¾ cup (~170 g) | 100 |
| 1 cup (~227 g) | 130 |
| 32 oz tub (~907 g) | ~530 |
If you buy individual 5.3 oz cups, you’re getting 80 kcal each — slightly less than the ¾ cup standard. Fine for portion control; expensive per ounce vs. tubs.
Add-Ins and Toppings
The base is 100 kcal. Common upgrades:
| Topping | Calories |
|---|---|
| 1 tbsp granola | 30 |
| ¼ cup granola | 130 |
| ½ cup berries | 25 |
| ½ banana | 50 |
| 1 tbsp chia seeds | 60 |
| 1 tbsp ground flax | 35 |
| 1 tbsp honey | 64 |
| 1 tbsp maple syrup | 52 |
| 1 tbsp peanut butter | 95 |
| ¼ cup nuts (mixed) | 200 |
| 1 tbsp jam | 50 |
| 1 oz dark chocolate, shaved | 170 |
A “yogurt parfait” with ½ cup yogurt + ¼ cup granola + ½ cup berries + 1 tbsp honey is ~270 kcal. Solid breakfast or snack.
Greek Yogurt as Sour Cream Sub
Standard substitution math:
| 1 cup of | Calories | Protein |
|---|---|---|
| Sour cream | 444 | 5 g |
| Plain nonfat Greek yogurt | 130 | 24 g |
| Plain whole milk Greek yogurt | 250 | 21 g |
A 1:1 swap of nonfat Greek for sour cream saves ~314 kcal per cup. On tacos, baked potatoes, or as a dip base, the texture and tang are nearly identical.
Flavored Yogurts — The Sugar Trap
A 5.3 oz strawberry Greek yogurt cup is around 140 kcal with ~17 g sugar (mostly added). Compare:
- Plain Greek yogurt + ½ cup fresh strawberries: 105 kcal, ~10 g natural sugar
- Strawberry-flavored Greek yogurt: 140 kcal, ~17 g (mostly added) sugar
You save ~35 kcal per cup and get fresh fruit instead of strawberry purée and added sugar. The flavored versions are convenient; not necessarily cheaper or healthier.
Greek Yogurt in Smoothies
Standard smoothie:
- 1 cup milk: 100 kcal
- 1 banana: 105 kcal
- ½ cup berries: 35 kcal
- ½ cup Greek yogurt (plain nonfat): 65 kcal
- 1 tbsp peanut butter: 95 kcal
- Total: ~400 kcal, ~22 g protein
Greek yogurt is a cheap way to bump smoothie protein without adding scoop-style protein powder. ½ cup adds 12 g protein for 65 kcal.
Greek Yogurt for Cooking
Hot tip: you can sub Greek yogurt for mayo in chicken/tuna salads:
| 2 tbsp of | Calories | Protein |
|---|---|---|
| Mayonnaise | 190 | 0 g |
| Greek yogurt + 1 tsp olive oil | 65 | 4 g |
The texture is a touch lighter; flavor is fresher. Great for everyday salads, less great for some traditional dressings where mayo’s texture is the point.
Common Logging Mistakes
Logging plain when you ate flavored. ~50 kcal/cup difference, easy to miss.
Logging “yogurt” when you ate Greek (or vice versa). They’re not the same — Greek has 2× the protein at similar calories.
Forgetting the toppings. Plain Greek + granola + honey + berries can be 350+ kcal. Log each.
Counting “Greek-style” non-Greek yogurts. Some brands market thicker non-Greek as “Greek-style” without the protein boost. Check the label.
What to Take Away
- Plain nonfat Greek yogurt = ~100 kcal/¾ cup with 18 g protein. Best protein-per-calorie in the dairy aisle.
- Flavored = +50 kcal of sugar. Add fresh fruit yourself.
- 2% and whole milk Greek are both fine on a deficit; 140–190 kcal/cup.
- Sub for sour cream and mayo to cut calories with no taste compromise.
Pair with calories in oatmeal and calories in an egg for breakfast planning.
Frequently Asked Questions
Is Greek yogurt better than regular yogurt for weight loss?
For protein per calorie, yes. Greek yogurt has roughly 2× the protein of regular yogurt at similar calorie counts because the whey is strained off.
How many calories in flavored Greek yogurt?
A typical 5.3 oz (150 g) flavored cup is 130–180 kcal — about 30–60 kcal higher than plain due to added sugar. Light versions (sweetened with stevia/erythritol) run closer to 80–100 kcal.
Is full-fat Greek yogurt bad for weight loss?
No. ¾ cup of whole milk Greek yogurt is ~190 kcal — fits in any deficit. Some research suggests full-fat dairy may improve satiety. Both work.
Can I substitute Greek yogurt for sour cream?
Yes — almost identical in tang and thickness, with 2× the protein and half the calories. A standard 1:1 swap saves ~50 kcal per ¼ cup.
