How many calories are really in your Leon order? Here's the full UK breakdown — calories, protein, carbs and fat — plus a way to log it in one tap.
Quick answer: Leon's Chargrilled Chicken Burger is around 432 kcal, the Aioli Chicken Rice Box about 680 kcal, and the Grilled Halloumi Wrap roughly 556 kcal. A regular portion of Baked Fries adds about 174 kcal (though one UK database lists them closer to 240).
Leon markets itself as "naturally fast food", but portions still range from a light 174 kcal side of fries to rice boxes north of 680 kcal once the aioli and slaw are added. The figures below come from published UK nutrition databases (CalorieKing UK and FatSecret UK); where a number is our estimate rather than a confirmed published figure we mark it with a "~".

Log your Leon free →A Leon Chargrilled Chicken Burger is around 432 kcal per portion (about 225-227g), with about 35g protein, 42g carbs and 17g fat. The chargrilled chicken thigh makes it one of Leon's more protein-heavy mains.
For fewer calories, lean towards a plain chargrilled chicken rice box (around 372 kcal) or a salad, and choose baked fries (about 174 kcal per regular 100g portion) over the loaded versions. Watch the aioli rice boxes and loaded fries, which push past 500-680 kcal thanks to added sauces.
A Leon Aioli Chicken Rice Box is about 680 kcal per 445g box, with roughly 27g protein, 59g carbs and 39g fat. Most of the fat comes from the yoghurt-based aioli. Note the separate 'Aioli Chicken with Rice & Slaw' variant is higher, around 842 kcal.
They are baked rather than deep-fried, so a regular 100g portion is around 174 kcal with about 7-8g fat (per CalorieKing UK), lower than most fast-food fries. One other UK database lists the same item closer to 240 kcal per 100g, so treat it as a rough figure. Loaded versions like the Cheezy Loaded Fries are much higher at roughly 528 kcal.
