The Key Factors: How Fat Content Affects Calories
When evaluating the calorie content of Greek yogurt, the most significant variable is the milkfat percentage. Greek yogurt is made by straining regular yogurt to remove excess whey, resulting in a thicker, tangier product with more protein and fewer carbohydrates than its unstrained counterpart. However, the fat from the milk remains, and its concentration directly influences the final calorie count.
Nonfat Plain Greek Yogurt (0% milkfat)
For those seeking the lowest calorie option, nonfat Greek yogurt is the ideal choice. According to nutritional data from sources like Nutritionix and Eat This Much, 100 grams of plain, nonfat Greek yogurt contains approximately 59 calories. This option is also notable for its very high protein content and minimal fat, making it an excellent food for satiety and muscle support without a high caloric cost.
Low-Fat Plain Greek Yogurt (around 2% milkfat)
Low-fat Greek yogurt provides a middle ground in terms of calories and richness. Depending on the brand, 100 grams of low-fat plain Greek yogurt can contain anywhere from 66 to 86 calories. The small amount of milkfat adds a bit more richness and a creamier texture compared to the nonfat variety, while still keeping the overall calorie count relatively low.
Full-Fat Plain Greek Yogurt (4-5% milkfat or more)
Full-fat Greek yogurt offers the richest taste and creaminess but comes with a higher calorie count. Nutrition data indicates that 100 grams of plain, whole milk Greek yogurt can have between 97 and 141 calories, with variations based on the specific brand and processing. This version is higher in saturated fat but can be beneficial for those who prefer the increased satiety and flavor that fat provides, which can help manage overall calorie intake throughout the day.
Beyond Calories: A Nutritional Comparison
While calories are important, it’s essential to look at the broader nutritional profile to understand the health benefits. Greek yogurt, regardless of fat content, is a nutrient-dense food rich in protein, calcium, and probiotics.
| Nutrient (per 100g) | Nonfat Plain Greek Yogurt | Full-Fat Plain Greek Yogurt | Regular Plain Yogurt (for comparison) |
|---|---|---|---|
| Calories | ~59 kcal | ~97 kcal | ~126 kcal (low fat) |
| Protein | ~10 g | ~9 g | ~10.5 g (low fat) |
| Fat | ~0.4 g | ~5 g | ~3.1 g (low fat) |
| Carbohydrates | ~3.6 g | ~4 g | ~14 g (low fat) |
| Sugar | ~3.2 g | ~4 g | ~14 g (low fat) |
| Calcium | ~110 mg | ~100 mg | ~150 mg (based on DV%) |
As the table shows, Greek yogurt consistently provides a higher protein concentration and lower carbohydrate content than regular yogurt due to the straining process. This makes it an excellent option for increasing protein intake, which is beneficial for weight management and muscle maintenance.
How to Make the Right Choice for Your Goals
Choosing the right Greek yogurt depends on your personal health and dietary goals. If you are focused on minimizing calories for weight loss, the nonfat variety is the best option. Its high protein content will help you feel full and satisfied. For those who prioritize flavor and texture and are not as concerned with maximizing protein per calorie, full-fat Greek yogurt offers a creamier, richer experience and can still be part of a healthy diet in moderation.
It is always best to choose plain, unsweetened Greek yogurt. Many flavored versions, including some low-fat options, are loaded with unnecessary added sugars and artificial ingredients that can negate their health benefits. You can control the sweetness and flavor by adding your own fresh fruit, a drizzle of honey, or nuts and seeds.

The Health Benefits of Plain Greek Yogurt
Regardless of the fat content you choose, incorporating plain Greek yogurt into your diet can provide several health advantages:
Promotes Gut Health
Greek yogurt contains live and active probiotic cultures, which are beneficial bacteria that help restore a healthy balance to your gut microbiome. A balanced gut can aid in digestion and potentially support the immune system.
Aids in Weight Management
Thanks to its high protein content, Greek yogurt can increase feelings of fullness and reduce overall calorie intake. Studies have shown that a high-protein diet can help reduce appetite and boost metabolism.
Supports Bone Health
Greek yogurt is a good source of calcium and protein, both of which are essential for maintaining strong bones and reducing the risk of osteoporosis.
Assists Muscle Recovery
The protein in Greek yogurt is excellent for muscle recovery and growth, especially when consumed after exercise. This makes it a perfect post-workout snack to help your body repair and build muscle mass.
Conclusion
To answer the question of how many calories are in 100g of plain Greek yogurt, there is no single number. The calorie count is directly tied to the fat content, with nonfat containing approximately 59 kcal and full-fat versions exceeding 97 kcal. By understanding these variations and focusing on plain, unsweetened options, you can make an informed choice that aligns with your nutritional and health goals while enjoying the many benefits this versatile food provides.
