Keto Approved
Parmesan
0.90g net carbs per 1 oz
Grated over eggs or shaved onto a salad, an ounce brings just 0.9 g net carbs alongside 10 g protein and 7 g fat. Buy a wedge and grate it yourself when you can, since the pre-shredded tubs sometimes add starchy anti-caking agents that nudge the carb count up.

Good to Know
Reach for a wedge of true Parmigiano-Reggiano (look for the rind stamp) or Grana Padano rather than the shelf-stable green canisters, which often add cellulose and anti-caking starch that nudge the carbs up. Freshly grated melts and crisps better, and a small amount goes a long way on roasted vegetables or whisked into eggs. Skip the pre-shredded bags labeled "pizza blend" if they list potato or corn starch, since those fillers add hidden carbs.
Is Parmesan Keto? The Full Answer
Parmesan contains 0.90g net carbs per 1 oz (0.90g total carbs minus 0.00g fiber). Grated over eggs or shaved onto a salad, an ounce brings just 0.9 g net carbs alongside 10 g protein and 7 g fat. Buy a wedge and grate it yourself when you can, since the pre-shredded tubs sometimes add starchy anti-caking agents that nudge the carb count up.
On a standard ketogenic diet, most people target 20-25g net carbs per day. A single serving uses 5% of a 20g daily carb limit. That makes Parmesan 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.
