Good to Know
Fresh fillets should smell clean and briny, never fishy, with flesh that springs back when pressed. Skip anything breaded or beer-battered, since a single coated portion can add 15 to 20 grams of carbs from the flour and crumbs. Frozen options like Wild Planet or a plain Costco Kirkland bag work fine, just check that the only ingredient is cod (some processed packs add a sodium tripolyphosphate solution that bumps water weight).
Is Cod (Atlantic) Keto? The Full Answer
Cod contains 0.00g net carbs per 3.5 oz fillet (0.00g total carbs minus 0.00g fiber). Very lean white fish. Use butter or olive oil for cooking to add fat.
On a standard ketogenic diet, most people target 20-25g net carbs per day. A single serving uses 0% of a 20g daily carb limit. That makes Cod 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.
