Fast food chains have long made their nutrition info available online, and in a number of markets around the country, this info has been posted in restaurants on menu boards for several years — but have you been paying attention?

Take our quick quiz to see if you can determine which fast food menu item has the highest calorie count.

We used the calorie counts published on each eatery’s website, and we tried to pair similar items together. To avoid items that are arguably identical in calorie count, each of the pairings in the quiz are at least 50 calories apart.

After the quiz, we’ll show you the full list of calorie counts.

Enough talk. Let’s eat!
