FAQs: Keto at Burger King

What can I eat at Burger King on keto?

Any burger without the bun and without ketchup. All flame-grilled beef patties are 0g carbs. Order 'no bun, no ketchup' every time. The Double Whopper with Cheese (no bun) is the best protein option at ~42g protein, ~3g net carbs.

Does Burger King UK do lettuce wraps?

No. Unlike US locations, Burger King UK uses shredded lettuce that can't form a wrap. Your bunless burger arrives in a box with a fork - perfectly fine, just not handheld.

Does Burger King UK have grilled chicken?

No. This is a key UK vs US difference. UK only offers crispy battered Chicken Royale and breaded Chicken Strips - both are high-carb and not keto-friendly. Stick to beef burgers.

Is the Rebel Whopper (plant-based) keto?

No! Even without the bun, the plant-based patty contains significant carbs from wheat and soy binders. This is a keto trap - always choose the regular beef Whopper instead.

How do I order keto at Burger King?

Say 'no bun, no ketchup' for every burger order. Ketchup adds 3g+ carbs per serving. Add jalapeños, mustard, and extra cheese for free. Your burger arrives in a box with a fork.
