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.
