Keto at Burger King
Burger King is a tougher keto stop than its rivals on paper. Its Nutrition Explorer lists every sandwich as a finished item, with the bun included, and does not publish the bun on its own. A Whopper is 57g of carbs as served, and there is no official number for a Whopper without the bun. You can still ask for one, but you would be estimating.
Among the items Burger King does publish, the lowest-carb choices are small orders of Chicken Fries, the Classic Flame-Grilled Chicken Wrap, and the low-sugar dipping sauces like ranch and Buffalo. The clear traps are the fries, onion rings, hash browns, shakes, and sweet sauces.

How to order keto at Burger King
- If you order a burger without the bun, know that Burger King doesn't publish bun nutrition, so the result can't be checked against official numbers.
- For the lowest published counts, choose a small order of Chicken Fries and dip them in ranch or Buffalo sauce.
- Skip the BBQ, honey mustard, and sweet and sour sauces, which are 8 to 18g of carbs a cup.
- Pass on fries, onion rings, and hash browns in every size.
- Drink unsweetened iced tea, Diet Coke, Coca-Cola Zero, or black coffee, all 0g carbs.
Net carbs are total carbohydrate minus dietary fiber, rounded to the nearest gram, from Burger King'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 Burger King before you order, especially for sauces, dressings, and seasonal items.
