Good to Know
Most full-fat jars deliver 11.5 g of fat per tablespoon with essentially no carbs, which is why it slots so easily into a keto plate. Brands like Primal Kitchen and Chosen Foods skip the sugar that sneaks into many supermarket versions, so a quick glance at the ingredient list pays off. Steer clear of "light" or "reduced-fat" tubs, since they often swap fat for starches and sweeteners that push the carb count up.
Is Mayonnaise (Full-Fat) Keto? The Full Answer
Mayonnaise contains 0.10g net carbs per 1 tablespoon (0.10g total carbs minus 0.00g fiber). Zero net carbs, high fat. Choose avocado oil mayo to avoid seed oils.
On a standard ketogenic diet, most people target 20-25g net carbs per day. A single serving uses 1% of a 20g daily carb limit. That makes Mayonnaise a reliable keto staple.
