Is Authentic Greek Feta Keto?

The Ingredient Breakdown

When evaluating any food for a ketogenic diet, the ingredient list is the first place to look. Fortunately, Authentic Greek Feta, protected by PDO (Protected Designation of Origin) status, has one of the cleanest and most straightforward ingredient profiles you can find.

The core components are simply PASTEURIZED SHEEP'S & GOAT'S MILK, SALT, CHEESE CULTURES, and MICROBIAL RENNET. Let's analyze these. The milk is the source of the fat and protein, while containing the natural milk sugar (lactose). However, the fermentation process used to create cheese consumes a significant portion of this lactose, leaving the final product very low in carbohydrates. The salt is essential for flavor and preservation in the brine, and it contains no carbs. Finally, cheese cultures and microbial rennet are enzymes and bacteria used to coagulate the milk; they are non-digestible and contribute zero carbs or calories. There are absolutely no fillers, starches, or hidden sugars in authentic feta.

Nutritional Value

From a nutritional standpoint, feta is a powerhouse for the keto diet. A standard serving of 1 ounce (28g) typically contains around 75 calories, with a significant portion coming from fat (approximately 6g) and protein (about 4g). The most critical metric for keto is the net carbohydrate count, which is exceptionally low. In that same serving, you'll find roughly 1 gram of total carbohydrate and 0 grams of fiber, resulting in 1 gram of net carbs. This minuscule carb impact means it's highly unlikely to disrupt ketosis, even when consumed in moderation. Its high fat content helps you meet your daily fat macro goals, while the protein promotes satiety, making it an excellent food for managing hunger on a low-carb diet.
