For Burger King keto ordering, ask for a Whopper or Cheeseburger without the bun and ketchup. For breakfast, request a Croissan’wich without its croissant. Leave off fries and breaded chicken; changing the burger doesn’t change the sides.
All figures below come from Burger King’s nutrition explorer, retrieved October 24, 2026. Values are as published by the chain per serving of the complete item.
Burger nutrition includes the bun
| Item (published serving) | Calories | Total carbs | Fiber | Net carbs | Protein | Fat |
|---|---|---|---|---|---|---|
| Whopper | 710 | 57g | 4g | 53g | 34g | 42g |
| Whopper Jr | 340 | 30g | 2g | 28g | 15g | 19g |
| Double Whopper | 980 | 57g | 5g | 52g | 56g | 62g |
| Bacon King | 1,260 | 58g | 4g | 54g | 69g | 84g |
| Rodeo Burger | 340 | 40g | 3g | 37g | 15g | 13g |
| Hamburger | 260 | 29g | 2g | 27g | 14g | 10g |
| Cheeseburger | 300 | 30g | 2g | 28g | 16g | 14g |
The Hamburger has the lowest total carbs among these full burgers. That doesn’t make it a low-carb meal as sold. Start with the burger you want, then ask for the bread and ketchup to be left off.
For a custom order, I would start with a Whopper or Cheeseburger and request no bun or ketchup. Ask what remains on the burger before adding anything extra. You want a clear order, not a royal decree that leaves everyone guessing.
Burger King’s nutrition explorer lists complete sandwiches, without separate bun or croissant portions. Removing the bread lowers the carbs, but it doesn’t give an exact total for the remaining filling.
Whopper and Double Whopper list the same total carbs as sold. Choose between them based on the amount of food you want, rather than expecting an extra patty to cancel the bread.
Rodeo Burger is a poor low-carb choice as sold at 40g total carbs. I’d keep the request simpler with a Whopper or Cheeseburger.
Breakfast: ask for the bread to be left off
| Item (published serving) | Calories | Total carbs | Fiber | Net carbs | Protein | Fat |
|---|---|---|---|---|---|---|
| Sausage Egg and Cheese Croissan’wich | 500 | 28g | 3g | 25g | 19g | 34g |
| Fully Loaded Croissan’wich | 620 | 31g | 3g | 28g | 30g | 43g |
Ask for a Sausage Egg and Cheese Croissan’wich without the croissant. Keep the request clear: filling only, with no replacement bread or potato side.
The Fully Loaded Croissan’wich is another breakfast option to request without its bread. Confirm exactly what the kitchen can serve before adding it to your order.
Sides, chicken and sauces
| Item (published serving) | Calories | Total carbs | Fiber | Net carbs | Protein | Fat |
|---|---|---|---|---|---|---|
| Royal Crispy Chicken | 600 | 54g | 4g | 50g | 31g | 31g |
| Small French Fries | 300 | 40g | 3g | 37g | 4g | 13g |
Small French Fries add 40g total carbs. Removing a burger bun and then adding fries doesn’t produce a counted low-carb meal.
Royal Crispy Chicken has 54g total carbs as sold. The chicken is breaded, so removing the sandwich bread still leaves the coating. I’d choose beef for this order.
Burger King’s nutrition explorer doesn’t list its dipping sauces or burger condiments separately, so keep extra sauce off and treat ketchup and sweet sauces as carbs you can’t count.
Complete orders, counted
These high-carb comparison orders include the standard sandwich with its bun and ingredients, plus Small French Fries. No drink or extra dip is included.
| Order | Calories | Total carbs | Fiber | Net carbs | Protein | Fat |
|---|---|---|---|---|---|---|
| High-carb comparison: Whopper + Small French Fries, both as sold | 1,010 | 97g | 7g | 90g | 38g | 55g |
| High-carb comparison: Cheeseburger + Small French Fries, both as sold | 600 | 70g | 5g | 65g | 20g | 27g |
The fries add a substantial carb serving to either sandwich. Order the burger on its own rather than accepting a side just to complete a combo.
