What Makes Greek Yogurt Different from Regular Yogurt
It is all about straining. Greek yogurt undergoes multiple strainings to eliminate excess whey, water, and lactose. This step will condense the protein and thicken the texture so that it can retain its form on a spoon. Regular yogurt doesn't undergo the additional straining and retains more of its liquid whey, which means it remains thinner and pourable.
This one production step accounts for nearly all the nutritional differences between the two. Whey concentrates contain the same amount of protein per ounce, but remove some lactose (which lowers sugar) and some calcium (which is typically bound to the whey). Unstrained regular yogurt retains more of the three - protein, natural sugar, and calcium.
Nutrition Facts Compared
Here’s how a 6-ounce (170g) serving of plain, unsweetened yogurt compares. These figures are approximate averages of plain varieties and may vary slightly from brand to brand.
| Nutrient | Greek Yogurt (plain, nonfat) | Regular Yogurt (plain, low-fat) |
| Calories | ~100 | ~140 |
| Protein | ~17g | ~8g |
| Total sugar | ~5g | ~15g |
| Carbohydrates | ~6g | ~16g |
| Fat | 0g | ~3.5g |
| Calcium | ~150-200mg | ~250-300mg |
The protein gap is the big one, but the calcium row often surprises people. While Greek yogurt is all the rage for being “more nutritious,” it doesn't necessarily have more calcium per serving than plain regular yogurt, as some of the calcium is removed during the straining process.

Which Yogurt Has More Protein?
Greek yogurt takes the cake here. A 6-ounce serving contains 15-19 grams of protein, whereas the same amount of regular yogurt contains 8-9 grams. The figure is nearly double, sometimes triple, depending on the brand.
The additional protein is more than just a number. Protein slows digestion, helping you stay full for longer and aiding muscle repair following exercise. If you're eating yogurt for breakfast, go for Greek yogurt. It provides about 10 grams of protein for every cup without significantly increasing your calorie intake. That swipe really is a game-changer for those leaning toward a high-protein breakfast or recovering from a workout.
Greek Yogurt vs Regular Yogurt for Weight Loss
As shown in the table above, most people find that Greek yogurt is more beneficial for weight loss than regular yogurt. Higher protein increases satiety, so a bowl of Greek yogurt keeps hunger at bay longer than the same-size bowl of regular yogurt. It is also thicker, which slows eating and may help reduce portion creep because it takes longer to eat.
There is a caveat: the benefit disappears quickly after purchasing flavored versions. Flavored Greek yogurt cups may contain 15-20 grams of added sugar, which can be just as much or more than the sugar found in flavored regular yogurt. The plain versus flavored choice is more important than the Greek versus regular. For weight loss, go for plain, unsweetened yogurt of both types and top with your own fruit or honey.
Taste and Texture Differences
Greek yogurt is noticeably tangier than drinkable yogurt and has a thicker consistency, more like sour cream than drinkable yogurt. Regular yogurt has less flavor, and is thinner and easier to pour, making it ideal for smoothies, salad dressings, and marinades.
Greek yogurt is also a popular ingredient in dips and baked goods, replacing sour cream or mayonnaise. It is lower in fat and doesn't separate when cooked. Regular yogurt blends in more smoothly with liquids and is effective in any situation where you want the yogurt to melt into the dish.
These very nutritional principles are incorporated into the Ideal Nutrition meal prep menu. Each meal is prepared by an executive chef team to meet protein and nutrition goals. When you're not sure you want to do the math on a Tuesday night to track the protein and sugar from each meal, our meal delivery service takes the decision off the table. Our menu offers more than 40 chef-prepared meals suitable for a wide range of diets, including keto, paleo, vegan, gluten-free and much more.

Which One Should You Choose?
Both types of yogurt have their advantages and disadvantages, so it's important to choose the one that best suits your goals. Go for Greek yogurt to add more protein, fewer carbs, and a thicker consistency for dips or high-protein bowls. Choose regular yogurt for a more subtle flavor, lower cost, or a thinner texture when using in cooking and baking.
They can both be included in a healthy diet if purchased plain and unsweetened and topped with your own ingredients. The flavored and sugary versions of either yogurt negate the nutritional benefits mentioned above, and the label is more important than the type of yogurt on the front of the container.
Frequently Asked Questions
Does Greek yogurt contain more protein than regular yogurt?
Yes. Plain Greek yogurt contains around 15-19 grams of protein per 6 oz. serving, while plain regular yogurt contains 8-9 grams of protein per 6 oz. serving.
Does Greek yogurt have less sugar than regular yogurt?
Yes, when it's plain and unsweetened. Straining also removes some of the lactose, which means that plain Greek yogurt typically contains less natural sugar than plain regular yogurt. But both flavored varieties can have the same amount of added sugar.
Can Greek yogurt be used in place of regular yogurt?
Typically, but it will be thicker and more tart. Greek yogurt can be used in place of sour cream or mayonnaise in baking. If the dressing or smoothie requires a thinner consistency, adding a splash of milk or water to Greek yogurt will come closer to the original texture.
Which yogurt contains more calcium?
Regular yogurt may have more calcium than Greek yogurt because some of the calcium is lost when the whey is strained out. They are both good sources of calcium.
Conclusion
The difference between regular yogurt and Greek yogurt is all in the straining process. Greek yogurt is higher in protein and lower in sugar, while regular yogurt retains more calcium and has a milder flavor. Always check the nutritional information and let your protein and calorie needs dictate which one goes in your shopping cart.
