Keto at Jack in the Box
Jack in the Box is a harder keto stop than most burger chains. Its nutrition chart lists each sandwich as a finished item and does not publish the buns separately, so there is no official number for a bunless Jumbo Jack. What it does publish is a strong salad: the Garden Salad with Grilled Chicken is 210 calories with 9g carbs and 3g fiber, before dressing.
Add buttermilk ranch (4g carbs) and you have a full meal near 10g net. Be careful with anything that sounds healthy. The Teriyaki Grilled Chicken Bowl is 100g of carbs because of the rice and sauce, and the tortilla strips and croutons on salads add carbs the salad numbers do not include.

How to order keto at Jack in the Box
- Make the Garden Salad with Grilled Chicken your main dish and ask for no tortilla strips or croutons.
- Choose buttermilk ranch or balsamic vinaigrette (4g carbs each). The Creamy Southwest dressing is 3g.
- Skip anything with rice, tortillas, or a "teriyaki" label, including the grilled chicken bowl.
- If you order a burger without the bun, know that Jack in the Box does not publish bun nutrition, so the carb count can't be confirmed.
- Drink iced black coffee, hot coffee, or a diet soda instead of the sweet cream coffees, shakes, or regular soda.
