Confused by Popeyes Uk calorie counts

[FancyBacon]

Somebody please help me understand inconsistency’s with popeyes calorie counts or if I’m missing something obvious

A classic chicken sandwich is listed as 599 calories on its own, or from 1131 in a box meal
A hot honey sandwich is listed as 595 calories on its own, or from 1040 in a box meal

From what I can see the sides are the same so I’m struggling to understand how the classic sandwich on its own gains 87 calories?

If a classic sandwich is 599, the lowest calorie extra is 174, lowest calorie fries is 283 and a 0 calorie drink = 1056

If you’re trying to lose weight Popeyes is the last place you should be thinking about. Failing that, bugger the calorie count and make it the only meal you have in any one day- that will keep you on track.
