Where the calories come from
A Big Mac is two beef patties, a slice of American cheese, Big Mac sauce, lettuce, pickles, and onions in a three-part bun. The bun brings most of the carbs and the patties most of the protein. The sauce is nearly all fat, as much as both patties together. These numbers are for the sandwich as McDonald's makes it in the US. McDonald's lists every ingredient and allergen on its Big Mac page.
| Part | Calories | Protein, fat, and carbs |
|---|---|---|
| Bun | 190 kcal | 7 g protein, 2 g fat, 37 g carbs |
| Two beef patties | 190 kcal | 15 g protein, 14 g fat, 1 g carbs |
| Big Mac sauce | 140 kcal | 1 g protein, 14 g fat, 4 g carbs |
| American cheese | 50 kcal | 3 g protein, 4 g fat, 1 g carbs |
From McDonald's nutrition calculator, with each part taken out in turn. Taking out the lettuce, pickles, or onions leaves the calories unchanged. The parts add up to 570 calories, not 580, because McDonald's rounds each number.
