Variations
Plain non-fat skyr
Plain skyr — 70 kcal per 100g — the base version and best for protein-to-calorie ratio. 11g protein, 0.2g fat, 6.05g carbs. Nearly all calories come from protein. The gold standard for high-protein, low-calorie dairy.
Whole milk skyr
About 90 kcal per 100g with ~4g fat. Creamier and richer than non-fat, while still maintaining high protein (~10g). Better suited for keto diets due to higher fat content. The extra fat improves mouthfeel and satiety.
Vanilla skyr
About 90 kcal per 100g with ~8g sugar (including added sugar). Protein stays around 9-10g. A convenient flavored option, but the added sugar increases carbs to ~10g per 100g. For fewer carbs and more protein, choose plain and add your own vanilla extract.
Fruit-flavored skyr
About 95 kcal per 100g with ~10g sugar. Protein drops to ~8-9g due to fruit and sugar additions. Carbs rise to ~12g per 100g. Still higher in protein than most flavored yogurts, but for the best nutritional profile choose plain skyr and add fresh berries yourself.
Dietary Perspectives
For Weight Loss
At 70 kcal per 100 g, skyr offers an excellent protein-to-calorie ratio. It provides 11 g of protein with only 0.2 g of fat and 6.05 g of carbohydrates per 100 g. A serving (~170 g, ~119 kcal) delivers nearly 19 g of protein — keeping hunger at bay for hours. The very low fat content means almost all calories come from protein. Choose plain over flavored to avoid added sugars.
For Keto
Skyr takes more of a keto budget than its reputation suggests: 6.05 g of carbohydrate per 100 g, and with no fibre all of it is net. One container (~170 g) has approximately 10.3 g of net carbs. Plain skyr also has only 0.2 g of fat per 100 g, which is very low for keto — pair it with nuts, seeds, or nut butter for a balanced meal. Whole milk skyr (~4 g fat, ~90 kcal) is a better fit. Avoid flavored varieties which can have 10+ g of sugar.
Frequently Asked Questions

Skyr vs Greek yogurt — what's the difference?
Skyr: 70 kcal, 11g protein, 6.05g carbs, 0.2g fat per 100g. Greek yogurt: 97 kcal, 9g protein, 3.98g carbs, 5g fat. Skyr has 22% more protein and 28% fewer calories, mainly because it is virtually fat-free. Both are strained dairy products, but skyr is technically a cheese, strained even more than Greek yogurt. Skyr is milder and thicker.
Is skyr good for weight loss?
Skyr is one of the best dairy products for weight loss. With 70 kcal per 100g and 11g of protein, it has an excellent protein-to-calorie ratio. One container (170g, ~119 kcal) delivers nearly 19g of protein — keeping you full for hours. The very low fat content means almost all calories come from protein. Avoid flavored varieties with added sugar.
Is skyr keto-friendly?
Skyr has 6.05g of carbohydrate per 100g and no fibre, so all of it counts as net carbs. One container (170g) has about 10.3g — a noticeable share of a 20g daily keto budget, so treat it as an occasional food rather than a staple. Plain skyr is also very low in fat (0.2g per 100g), so pair it with nuts or seeds for a balanced keto meal. Whole milk skyr (~4g fat) is a better fit.
What is skyr made from?
Skyr is made from skim milk and live bacterial cultures (including Streptococcus thermophilus). The milk is heated, cultures are added, and the mixture is strained extensively to remove whey — even more than Greek yogurt. This extreme straining concentrates the protein while keeping calories very low. Traditional Icelandic skyr uses rennet, making it technically a fresh cheese rather than a yogurt.
