The lightest main on the McDonald's UK menu is the plain Hamburger at 255 calories, half a Big Mac. But Boone's ranking shows the main is rarely the biggest decision: switching a large Coca-Cola for a zero sugar version removes 211 calories, and large Fries to small removes 207, which is more than the gap between most burgers. Below is every one of the 151 items on the UK menu, ranked from lowest calories upward and split by menu section. Set the age and sex and each figure recalculates as a share of that person's day.
































The full McDonald's UK breakfast menu ranked from lowest calories upward. A Hash Brown is lowest at 127 and plain Porridge is 154, the lightest thing on the menu that counts as a meal. Adding sugar takes Porridge to 166 and golden syrup takes it to 326, so the base is light and the toppings are not.
























McDonald's UK sides, fries and dips from lowest calories upward. The sachets sit at the bottom, from 2 calories for a sweetener to 27 for ketchup. Among actual sides, the Side Salad is lowest at 58 and small Fries are 237. Swapping large Fries for small removes 207 calories, more than a whole Apple Pie.

























McDonald's UK desserts from lowest calories upward. The Oreo Mini McFlurry is lowest at 130, roughly half a regular one, and the mini range fills the bottom of this section between 130 and 162. If you want dessert and want it light, size matters far more than flavour here.














McDonald's UK cold drinks from lowest calories upward, and this is where the biggest savings on the whole menu sit. Still water is zero, Coca-Cola Zero Sugar and Diet Coke are 1 calorie each, and the Sprite and Fanta Zero range runs from 4 to 12. Switching a large Coca-Cola Classic for a zero sugar version removes 211 calories and changes nothing else about the order.


































McDonald's UK hot drinks from lowest calories upward. An Espresso is 1 calorie, an Americano 6 and Tea 6. A White Coffee is 54 and a plain Latte 145, so the milk accounts for almost the entire range. This is the lightest section on the menu.









The McDonald's Happy Meal and kids range from lowest calories upward. Milk Portion is 5, Robinsons Fruit Shoot 8, Cucumber Sticks 12 and Melon Chunks 17. Because the sides and drinks are so light, the choice of main decides almost the whole meal: the McNuggets Happy Meal is lowest at 311 and the Cheeseburger highest at 440.
