Plain, unsweetened yogurt can be a staple in a healthy diet, but its calorie count is far from uniform. The number of calories depends primarily on the fat content of the milk used to make it. This guide breaks down the typical calorie ranges for different types of unsweetened yogurt, from full-fat to nonfat, and even compares traditional to Greek and Icelandic varieties.
The Breakdown of Yogurt Calories
When examining the nutritional information for unsweetened yogurt, it's crucial to understand that the calories don't come from added sweeteners. Instead, they are derived from the yogurt's three primary macronutrients: fat, protein, and carbohydrates (specifically, the naturally occurring milk sugar, lactose).
Fat Content and Its Calorie Contribution
- Whole Milk Yogurt: Plain whole milk yogurt contains the highest amount of fat and, consequently, the highest calorie count. The creamy, rich texture is a result of this higher fat percentage. For example, a 100-gram serving of whole milk plain yogurt can have about 61 calories, with a significant portion coming from its 3.3 grams of fat. A full 1-cup serving (240g) can be around 149 calories.
- Low-Fat Yogurt: With some of the milk fat removed, low-fat yogurt has a reduced calorie count compared to its whole milk counterpart. It offers a good balance of creamy texture and a lighter calorie profile. Per 100 grams, low-fat plain yogurt contains fewer calories and less fat than whole milk versions.
- Nonfat Yogurt: For those looking to minimize fat and calories, nonfat plain yogurt is the best choice. For instance, a 100-gram serving might contain as few as 63 calories. The calorie reduction comes almost entirely from the absence of milk fat.
Comparing Different Types of Unsweetened Yogurt
Not all unsweetened yogurts are created equal. The straining process and milk source can lead to significant differences in calorie and protein content. Here’s how common types compare:
Traditional vs. Greek vs. Icelandic
- Traditional Plain Yogurt: Unstrained and less concentrated than other varieties, traditional yogurt has a thinner consistency. Calories in a cup of plain traditional yogurt (full-fat) are around 150.
- Greek Plain Yogurt: Strained to remove excess whey, Greek yogurt is thicker and has a higher protein concentration. This process also increases its overall calorie density compared to traditional yogurt of the same fat percentage. A cup of plain, full-fat Greek yogurt contains approximately 215 calories.
- Icelandic Yogurt (Skyr): Even thicker than Greek yogurt due to a longer straining process, Icelandic yogurt typically has a very high protein content and a tangy flavor. Calorie counts vary, but they are generally comparable or slightly higher than Greek yogurt.
Plant-Based Unsweetened Yogurt
For those who do not consume dairy, plant-based unsweetened yogurts offer an alternative. Calorie counts depend on the base, such as almond, soy, or coconut milk. For example, an unsweetened almond milk-based Greek yogurt can have 150 calories per serving. Always check the label, as formulations can differ greatly.
Comparison Table: Calories in Unsweetened Yogurt (per 100g)
| Type of Yogurt | Calories (kcal) | Fat (g) | Protein (g) | Natural Sugar (Lactose) (g) |
|---|---|---|---|---|
| Traditional Plain Whole Milk | ~61 | ~3.3 | ~3.5 | ~4.7 |
| Traditional Plain Low-Fat | ~63 | ~1.6 | ~5.3 | ~7 |
| Traditional Plain Nonfat | ~56 | ~0.2 | ~5.7 | ~8 |
| Greek Plain Whole Milk | ~89 | ~4.4 | ~8.7 | ~6 |
| Greek Plain Nonfat | ~81 | ~0.2 | ~15.2 | ~6.5 |
Note: These are average figures and can vary by brand and processing. Always consult the product's nutrition label for precise information.
How to Find Accurate Calorie Information
- Read the Nutrition Facts Label: This is the most reliable source for calorie information. Pay close attention to the serving size, as this can differ between brands. Also, check the 'Includes Added Sugars' line, which should be 0g for truly unsweetened products.
- Understand Natural Sugars: The 'Total Sugars' line will not be zero, as it includes lactose, the natural sugar found in milk. The amount of lactose can vary slightly, but it doesn't represent added sweeteners. A genuinely unsweetened yogurt will only have naturally occurring sugars.
- Recognize the Importance of Fat Content: A higher percentage of milk fat will always result in a higher calorie count. If you're managing calorie intake, opt for low-fat or nonfat versions.
- Know the Different Yogurt Types: Traditional, Greek, and Icelandic yogurts all have different consistencies and nutritional profiles. Greek and Icelandic yogurts, while higher in protein, are also more calorie-dense than traditional options with the same fat percentage due to their strained nature.
Conclusion
Ultimately, how many calories are in yogurt without sugar depends on its type and fat content. Nonfat varieties are the lowest in calories, while full-fat Greek and traditional yogurts have the most. A good rule of thumb is to check the nutrition label for the fat percentage and serving size to determine the exact calorie load. Unsweetened yogurt remains a nutrient-dense food, providing protein, calcium, and probiotics with minimal calories compared to its sweetened counterparts.

Your Daily Yogurt Choice
- Nonfat Plain Greek Yogurt: A 6-ounce (170g) serving of this option typically provides around 100 calories and is packed with protein.
- Plain Whole Milk Yogurt: A one-cup serving (about 245g) contains roughly 149 calories, making it a satiating, higher-fat option.
- Low-Fat Plain Yogurt: Providing a middle ground, this variety offers a moderate calorie count while still delivering good nutrition.
- Icelandic Yogurt (Skyr): This type is generally higher in protein and denser than Greek yogurt, so its calorie count can be substantial.
- Plant-Based Unsweetened: Calories can vary significantly based on the plant source (e.g., coconut, almond, or soy), so checking the label is essential.
