Fast Food
A McDonald's Big Mac contains approximately 550 calories, making it one of the more calorie-dense fast food burgers on the market. The biggest contributors to watch are the two beef patties, the signature Big Mac sauce, and the triple-layered sesame seed bun, which together account for the majority of its fat and carbohydrate load. While it offers a decent hit of protein (~25g), it is also notably high in sodium (~1,010mg — about 44% of the daily recommended limit), so it's worth factoring into your overall daily intake.

Portion Tips
- 1.
Skip the combo meal — ordering the Big Mac alone (without fries and a large soda) can save you 500–800 additional calories in a single sitting.
- 2.
Ask for the Big Mac sauce on the side so you can control how much you use; the sauce alone adds ~90 calories.
- 3.
Opt for water or an unsweetened drink instead of a regular soda — a large Coke adds about 290 calories on top of your meal.
- 4.
If you're still hungry, add an apple slice bag (~15 cal) rather than small fries (~230 cal) to keep the meal more balanced.
- 5.
Consider eating only one half of the burger slowly before deciding if you need the rest — the middle bun layer adds extra carbs that you may not miss.
