A blonde woman with gray eyes, wearing a red and white patterned top, enjoys a burger at a Jack in the Box restaurant, holding it with both hands and taking a bite, her red nails visible, against a slightly blurred fast-food restaurant background.

Jack in the Box has a published nutrition menu but doesn’t label their keto foods and drinks, so we compiled a complete Jack in the Box keto menu with all categories listed from their main menu for anyone to reference.1

We’ve included all 177 Jack in the Box low carb options and the net carbohydrates for each, as well as breakfast, taco, and burger hacks to lower the amount of carbs in each and make these foods more keto-friendly.
