Good to Know
Brined blocks (think Président or the barrel-aged Greek styles from Dodoni) tend to taste sharper and keep their texture better than the pre-crumbled tubs, which sometimes get dusted with anti-caking starch that nudges the carbs up a touch. Sheep and goat milk versions run a little tangier than cow's milk feta, but the macros stay close either way. Pre-marinated versions packed in oil with sun-dried tomatoes or honey can sneak in added sugar, so plain brine is your safest bet.
Is Feta Keto? The Full Answer
Feta contains 1.10g net carbs per 1 oz (1.10g total carbs minus 0.00g fiber). Crumble an ounce over a salad and you're looking at just 1.1 g net carbs, plus 6 g fat and 4 g protein to round out the day. The fat-forward ratio makes it an easy salty add-on when you want flavor without spending much of your carb budget.
On a standard ketogenic diet, most people target 20-25g net carbs per day. A single serving uses 6% of a 20g daily carb limit. That makes Feta a reliable keto staple.
Measure Your Ketone Levels
A blood ketone meter reads beta-hydroxybutyrate from a finger prick, the marker that defines nutritional ketosis at 0.5 to 3.0 mmol/L. Urine strips measure acetoacetate instead, which drops off once you are fat-adapted. Keto-Mojo makes a blood meter.
