Variations
Plain non-fat skyr
62 kcal per 100g — the base version and best for protein-to-calorie ratio. 11g protein, 0.2g fat, 3.8g 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 just 62 kcal per 100 g, skyr offers an exceptional protein-to-calorie ratio. It provides 11 g of protein with only 0.2 g of fat and 3.8 g of carbohydrates per 100 g. A serving (~170 g, ~105 kcal) delivers nearly 19 g of protein — keeping hunger at bay for hours. The virtually zero fat content means almost all calories come from protein. Choose plain over flavored to avoid added sugars.
For Keto
Skyr is moderately keto-friendly with 3.8 g of net carbs per 100 g (3.8 g total carbohydrates, 0 g fiber). One container (~170 g) has approximately 6.5 g of net carbs — manageable within a daily keto budget. However, plain non-fat skyr 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 keto meal. Whole milk skyr (~4 g fat, ~90 kcal) is a better fit for keto. Avoid flavored varieties which can have 10+ g of sugar.
