The whole menu at a glance

Each dot is one item. The UK government’s 400-600-600 guidance suggests about 600 kcal for lunch or dinner, so anything past the line is more than a whole meal on its own.

600 kcal or lessOver 600 kcal

A Breakfast King carries 34.7g of protein, more than anything else on the Burger King menu apart from the doubles, and 1.8g of salt, which is 36% of the daily limit for a 7 to 10 year old before anything else that day. The hot drinks alongside it are where the sugar sits: none of the milk coffees carry any free sugar at all, because milk sugars do not count, while a hot chocolate carries about 10g.

The 2 breakfast items range from 328.8 kcal for the Burger King Sausage Butty up to 505.5 kcal for the Burger King Breakfast King, with seven hot drinks listed alongside them. Boone separates free sugars from the sugars that occur naturally in milk, which NHS daily limits do not count, and measures every figure against the guideline for a specific age and sex rather than an adult average.

Corrections. Figures that cannot be right are corrected, and free sugar is worked out from the ingredients where they are published.

Guidelines. UK government and NHS limits by age and sex. Healthiest and unhealthiest rankings use the UK nutrient profiling model.

Allergens. Always check with the restaurant if you have an allergy.

Images. Item images are illustrations created by Boone, not photographs.

Common questions

What nutrition information is shown for Burger King Breakfast?+

Each Burger King Breakfast item is listed with its calories, sugar, salt, saturated fat and protein, and how much of the daily guideline it uses. Open any item for the full breakdown and allergens.

How does the Burger King Breakfast nutrition calculator work?+

Open any Burger King Breakfast item and set an age and sex. The calculator shows its calories, sugar, salt, saturated fat and protein as a share of that person's daily guidelines, and you can adjust the portion size.

Can I add sides and drinks to see a full Burger King meal?+

Yes. Start with any Burger King Breakfast item, then add sides, drinks and sauces from across the Burger King menu. The calculator totals the meal and shows how it fits the daily guidelines for your age and sex.

How are the daily guidelines worked out for my age and sex?+

Boone uses UK government and NHS guidelines, which differ by age and sex. Saturated fat is limited to 20g a day for women and 30g for men, and free sugar to 30g for adults but 19g for children aged 4 to 6. Choosing an age and sex recalculates every figure against the right limits.

Why does the calculator show different figures for children?+

Children have lower limits for free sugar and salt and need less energy, so the same item uses a bigger share of their day. A child aged 4 to 6 has a limit of 19g of free sugar and 3g of salt, compared with 30g and 6g for an adult.

Where does Boone's Burger King nutrition information come from?+

Boone uses the nutrition and allergen information Burger King publishes for its UK menu, then calculates free sugar and how much of the daily guidelines each item uses for your age and sex.

Does the Burger King Breakfast nutrition information include allergens?+

Yes. Each Burger King Breakfast item page lists the allergens Burger King declares, including where cross-contamination cannot be ruled out. If you have a severe allergy, always check with the restaurant before ordering.

Why is the sugar figure different from Burger King's own nutrition information?+

Burger King publishes total sugar, which includes the sugar naturally found in milk and whole fruit. NHS limits apply only to free sugars, so Boone separates the two and measures free sugar against your daily limit. That is why an item can use less of your limit than its total sugar suggests.
