It is an excellent choice for those looking to maintain a state of fat burning while enjoying a creamy, fruit-flavored snack.

The Ingredient Breakdown

To understand why this product works for the keto diet, we need to look at its primary component: Quark bajo en grasa (low-fat quark). This is essentially a fresh cheese made from skimmed milk. It is naturally low in carbohydrates and high in protein, making it an ideal base for a keto diet. The product is listed as containing leche desnatada pasteurizada (skimmed pasteurized milk), which is acceptable on keto as the lactose content is minimal and the protein content is high.

Next, we look at the sweetening agents. The product uses steviol glugosida (E960), which is Stevia. This is a plant-derived, zero-calorie sweetener that does not impact blood sugar levels, keeping the net carb count extremely low. It also lists concentrado de zumo de fruta (fruit juice concentrate). While fruit juices usually contain sugar, the amount here is restricted to just 4.5% of the product. Combined with the lack of added cane sugar, the total carbohydrate load remains negligible.

Finally, the texture and color come from ingredients like fécula de maíz (cornstarch) and E440 pectinas (pectin). Cornstarch is a starch, but it is used in very small quantities as a thickener. In a serving size of roughly 150g, the amount of cornstarch contributes less than 0.5g of net carbs. The extracto de bálsamo de limón (lemon balm extract) and natural aromas add flavor complexity without adding carbs.

Nutritional Value

When evaluating a product for ketosis, the most critical metric is the Net Carb count. While the specific label numbers can vary slightly by batch, a typical serving of this strawberry quark contains approximately 5g to 6g of total carbohydrates per 150g serving. However, a significant portion of this comes from the milk lactose and the fruit concentrate. Crucially, because the product uses Stevia, it contains 0g of added sugar. Assuming roughly 2g of fiber (from the pectin and fruit structure), the Net Carbs likely land between 3g and 4g per serving. This is well within the standard keto limit of 20g net carbs per day.

Fat content is the other pillar of the keto diet. This product is labeled "bajo en grasa" (low fat), meaning it is not designed to be a high-fat meal. It will likely contain around 1.5g to 2g of fat per serving. While this is low, it is perfectly acceptable for a keto snack. On keto, you do not need every single food item to be high fat; you simply need to keep carbs low and protein moderate. You can easily pair this quark with a handful of macadamia nuts or chia seeds to increase the fat content if desired.
