Understanding the Carb Count in Yogurt
At its core, yogurt is a fermented dairy product. The bacteria cultures consume some of the natural milk sugar, or lactose, converting it into lactic acid. This is why plain, unsweetened yogurt has fewer carbs than an equivalent amount of milk. However, the true carb count depends heavily on the manufacturing process and whether any sugars or flavorings are added.
The Impact of Straining
The biggest factor separating traditional yogurts from low-carb varieties is the straining process. Greek and Icelandic skyr are both strained to remove excess whey, the watery part of milk. Since whey contains most of the lactose, straining significantly reduces the final carbohydrate content and results in a thicker, creamier texture with a higher protein concentration. This is why plain Greek yogurt and Icelandic skyr are consistently the top picks for low-carb and keto diets. In contrast, unstrained or regular yogurt retains more whey, and thus, more lactose, making it higher in carbs.
Beware of Added Sugars
Even if a yogurt is labeled 'Greek' or 'Icelandic', it can still be packed with carbs if it contains added sugar for flavor. Fruity or dessert-inspired flavors often contain high amounts of added sugar that can quickly derail a low-carb eating plan. Always read the nutrition label carefully, focusing on the "Total Carbohydrates" and "Added Sugars" lines. Many brands now offer "zero sugar" or "lower sugar" options that use alternative sweeteners, which are often a safer bet, but it's still best to check the ingredients.
The Top Low Carb Yogurt Contenders
Plain Greek Yogurt
As a widely available and popular option, plain Greek yogurt is a go-to for low-carb diets. It offers a great balance of high protein, healthy fat (especially in full-fat varieties), and a modest carb count, all thanks to the straining process. Brands like Fage and Chobani offer excellent plain options with minimal carbs.
Icelandic Skyr
Skyr is a cultured dairy product from Iceland that is even thicker and more protein-dense than Greek yogurt. It requires significantly more milk to produce and is strained to remove almost all the whey. This results in an incredibly high-protein, low-carb yogurt alternative. Popular skyr brands include Siggi's and Icelandic Provisions.
Specialized Low Carb and Keto Brands
Some brands specifically market themselves for low-carb or ketogenic lifestyles. Products like Ratio Keto Friendly Dairy Snack are formulated to have a minimal carb impact while maintaining flavor. Chobani also offers a 'Zero Sugar' line that uses natural sweeteners and contains no sugar, making it another valid choice.
Plant-Based Alternatives
For those who are dairy-free, low-carb plant-based yogurts exist, typically made from almond or coconut milk. However, these can be a mixed bag and require careful label reading. While some, like Ratio's plant-based option, are low-carb, many others add thickeners and sweeteners that increase the carb count.

Tips for Enjoying Low Carb Yogurt
Choose Plain and Add Your Own Toppings
To have complete control over your carb intake, always start with a plain, unsweetened variety. Instead of relying on pre-sweetened versions, add your own low-carb toppings such as:
- Fresh berries (strawberries, blueberries)
- Chopped nuts (almonds, walnuts)
- Chia or flax seeds
- A few drops of a natural zero-calorie sweetener like stevia or monk fruit
Use It in Recipes
Low-carb yogurt isn't just for eating with a spoon. You can use it as a healthy, tangy base in many recipes:
- Smoothies: Blend plain low-carb yogurt with spinach, protein powder, and a few berries for a meal replacement shake.
- Dressings and Dips: Swap out sour cream or mayonnaise for plain Greek yogurt in savory dips and dressings.
- Baking: Use it to add moisture to low-carb bread or muffins.
Consider Making Your Own
For the ultimate control over carb content, particularly for those on a very strict ketogenic diet, homemade yogurt is an excellent option. By fermenting for 24 hours or more, the bacteria can consume almost all of the lactose, resulting in a nearly carb-free product. Making it at home also allows you to choose your milk source, such as full-fat or organic A2 dairy.
Conclusion
While many yogurts are loaded with sugar, there are several delicious and healthy low-carb options available. The best choices are typically plain, unsweetened Greek yogurt and Icelandic skyr, which offer a high-protein, low-carb profile thanks to their straining process. For flavored yogurts, brands like Chobani Zero Sugar and Ratio offer good alternatives that use non-sugar sweeteners. The key to making the best choice is to always check the nutrition label for added sugars and practice portion control. By choosing wisely and adding your own healthy toppings, you can easily incorporate yogurt into a successful low-carb diet.
