McDonald's calories: Big Mac, meals & fries
Reference values from the US menu, item by item — as a range, because your real portion varies. And how to get the number for your order from a photo.
A Big Mac is about 590 kcal on the US menu; a Big Mac with medium fries is around 910 kcal before the drink. Here are the main reference values — take them as ranges, since your real portion and sauces shift the total.
Source: McDonald’s official nutrition. Values vary by country, portion and period — hence ranges. In France the recipe differs (Big Mac around 503–530 kcal).

Why fast food calories vary so much
Two “identical” orders can differ by 300 to 500 kcal. That is why a single number misleads, and a range tells the truth.
Portion and recipe. Bun size, patty thickness, cheese, breaded or grilled: from one chain and country to another, the same name hides different recipes.
Sauces and sides. A dose of sauce, large fries instead of medium, a sugary drink instead of diet: that is often where the hidden calories are.
What matters is the day’s total. Fast food is not forbidden: what counts is your overall intake. Tracking as a range avoids false precision and guilt.
