The Big Mac at McDonald's (1 sandwich (219g)) contains 590 calories, with 25g of protein, 46g of carbs, and 34g of fat. Below is the full nutrition breakdown, how it compares to other burgers on the menu, and the fastest way to log it.

Where the calories come from

Splitting the 590 calories by macro: 17% from protein, 31% from carbs, and 52% from fat. In the Big Mac, fat is the biggest contributor at roughly 52% of calories (34g × 9 cal/g). That makes the big mac more calorie-dense than the gram counts suggest — small portion differences move the total quickly.

Lighter swaps and ordering tips

Standard build with Big Mac sauce; ordering without the middle bun saves ~80 kcal.

Keep in mind that published numbers describe the standard build — every added sauce, swapped side, or upsized portion moves the totals from the table above.

The fastest way to log a McDonald's order

Official numbers like the ones above describe a textbook big mac — not the one with extra cheese or the sauce you asked for on the side. Instead of hunting through a database for the closest match, take a photo in Bento Bunny: the app recognises what's actually on the tray, estimates portions, and files the macros into your day. On iOS 26+ the AI runs entirely on-device.
