Good to Know
Aged cheddar (think Cabot Seriously Sharp or Tillamook Extra Sharp) tends to be drier and lower in lactose than mild versions, which keeps carbs minimal. Skip pre-shredded bags when you can, because brands often dust the strands with potato starch or cellulose to stop clumping, and that quietly nudges the carb count up. For melting over eggs or topping a burger, a block you grate yourself gives you the cleanest macros.
Is Cheddar Cheese Keto? The Full Answer
Cheddar Cheese contains 0.60g net carbs per 1 oz (1 slice) (0.60g total carbs minus 0.00g fiber). Slice it onto burgers or eat it straight, since each ounce carries just 0.6 g net carbs alongside 9.5 g fat. That fat-to-carb ratio makes it an easy pick when you need something filling between meals.
On a standard ketogenic diet, most people target 20-25g net carbs per day. A single serving uses 3% of a 20g daily carb limit. That makes Cheddar Cheese a reliable keto staple.
