Good to Know
One tablespoon brings 11.5 g fat and 102 calories with essentially nothing else, so it slides into a fat coffee or melts over steamed broccoli without touching your carb count. Skip whipped versions and butter blends like Country Crock or I Can't Believe It's Not Butter, since those often cut in vegetable oils, water, or even a little sugar. For cooking, butter starts to brown around 350F, so use ghee or tallow if you need higher heat for searing.
Is Butter (Unsalted) Keto? The Full Answer
Butter contains 0.00g net carbs per 1 tablespoon (0.00g total carbs minus 0.00g fiber). Zero carbs, all fat. Grass-fed (like Kerrygold) adds more CLA and omega-3.
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 Butter a reliable keto staple.
