The question, "is Greek yogurt high or low-carb?" is a common one, and the answer is that plain, unsweetened Greek yogurt is generally low in carbohydrates, but there are several factors that can change this significantly. Its low-carb status comes from the unique straining process that removes much of the lactose, or milk sugar, which is the primary source of carbohydrates in dairy. Plain varieties are highly compatible with many low-carb and ketogenic diets due to their lower sugar and higher protein content.
The Straining Process: How Greek Yogurt Gets Low-Carb
Traditional yogurt is made by fermenting milk, but Greek yogurt undergoes an extra step: straining. This removes a substantial amount of the liquid whey, which is a byproduct that contains lactose. By removing the whey, the remaining product is a thicker, denser yogurt that is not only richer in protein but also lower in carbohydrates. The total carbohydrate count is primarily made up of the remaining lactose, which varies depending on the manufacturer and the duration of the straining process.
Plain vs. Flavored: The Carb Difference is Huge
When navigating the yogurt aisle, the plain, unsweetened varieties are your best bet for a low-carb choice. Flavored Greek yogurts, even those with real fruit, often contain a significant amount of added sugars, which can dramatically increase the carbohydrate count. Some flavored options can have as much sugar as a dessert, negating any low-carb benefits you might be seeking. It's crucial to examine the nutrition label and ingredient list carefully to avoid hidden sugars. Always opt for plain versions and sweeten them yourself with low-carb additions like a handful of berries or a keto-friendly sweetener.
Low-Carb Greek Yogurt Options
There are several ways to incorporate Greek yogurt into a low-carb lifestyle. For example, plain full-fat Greek yogurt is an excellent option for those following a ketogenic diet, as it offers a higher fat content alongside its low carbs and high protein. Non-fat Greek yogurt, while lower in calories and fat, has a slightly higher carbohydrate percentage relative to its fat content, so it’s important to check the label for each specific product. For those with more flexible low-carb diets, a moderate serving of non-fat or low-fat plain Greek yogurt can still fit within daily carb limits.
Greek Yogurt in Low-Carb Cooking
Greek yogurt's versatility makes it a fantastic ingredient for low-carb cooking and snacking. It can be used as a:
- Sour cream substitute: Use it in dips like tzatziki or to top low-carb dishes.
- Smoothie base: Create a creamy smoothie with low-carb ingredients like berries, nut butter, and protein powder.
- Breakfast bowl: Combine with crushed nuts, chia seeds, and a few berries for a satisfying morning meal.
- Marinade ingredient: The acidity in Greek yogurt helps tenderize meat, making it great for chicken marinades.
Comparison Table: Greek vs. Regular Yogurt (Per 170g Serving)

How to Choose the Right Greek Yogurt
To ensure you're getting a genuinely low-carb Greek yogurt, follow these tips:
- Read the Label: Always check the nutrition facts for the total carbohydrate and sugar content per serving.
- Choose Plain and Unsweetened: This is the easiest way to control your sugar and carbohydrate intake.
- Opt for Full-Fat on Keto: If you're on a ketogenic diet, the full-fat variety provides more satiating healthy fats.
- Monitor Portion Sizes: Even with low-carb options, consuming large quantities can add up and affect your daily carb goals.
Conclusion
Plain, unsweetened Greek yogurt is low-carb due to its unique straining process, which removes much of the naturally occurring milk sugar, lactose. However, the carbohydrate content can escalate rapidly with added flavorings, fruits, and sweeteners. For those seeking a truly low-carb option, plain Greek yogurt is a versatile and nutritious choice, especially when compared to regular yogurt, which contains roughly double the carbohydrates. By being a diligent label-reader, you can ensure that this high-protein powerhouse remains a valuable part of your low-carb or keto-friendly diet. For more information on navigating low-carb dairy options, consider consulting reputable nutritional resources such as the guide found at BetterMe.
Note: While plain Greek yogurt is naturally low in carbohydrates, it is not carb-free. Always consider your daily dietary limits when incorporating it into your meal plan.
The Health Benefits of Greek Yogurt Beyond Carbs
Beyond its macronutrient profile, Greek yogurt offers several other health benefits. It is an excellent source of protein, which is vital for building and repairing tissues. This high protein content can also increase satiety, helping you feel fuller for longer and potentially aiding in weight management. Additionally, many Greek yogurts contain live and active probiotic cultures that support gut health by introducing beneficial bacteria to your digestive system. It also provides essential micronutrients such as calcium, phosphorus, potassium, and B vitamins like B12. The combination of protein, healthy fats (in full-fat versions), and low sugar makes it a nutrient-dense food that supports overall well-being, especially for those managing blood sugar levels.
