Keto at Whataburger
Whataburger makes keto ordering easy because "No Bun" is a standard bread choice in its online ordering menu, and the nutrition panel updates when you pick it. A Whataburger goes from 590 calories and 62g of carbs on the large bun to 280 calories and 6g of carbs without it. The patties carry almost nothing; the remaining carbs come from the tomato, onion, pickles, and mustard.
The Grilled Chicken Garden Salad is the other strong choice, at 13g of carbs with 10g of fiber before dressing. Watch the fries, onion rings, shakes, and breakfast biscuits and taquitos, which are all well past a keto budget.

How to order keto at Whataburger
- In the app or online, choose "No Bun" under Bread. At the counter, ask for any burger with no bun.
- Add patties instead of sides. A Triple Meat Whataburger with no bun is still 6g carbs.
- Mustard is the standard sauce on a Whataburger. Skip sweet sauces like Honey BBQ and Sweet & Spicy, and keep the default mustard or add mayo.
- Pick the Grilled Chicken Garden Salad if you want a lighter meal, and skip crunchy toppings.
- Drink water, unsweetened tea, or a diet soda instead of a shake or regular soda.
Net carbs are total carbohydrate minus dietary fiber, rounded to the nearest gram, from Whataburger's published nutrition information (checked October 2026). For a modified order, such as no bun, we subtract the published values of the part you leave off. Menus and recipes vary by location and change over time, so check current nutrition with Whataburger before you order, especially for sauces, dressings, and seasonal items.
