What that costs in movement
At 75 kg, this item is roughly 73 minutes of brisk walking or 38 minutes of easy running. That is an energy comparison and nothing more: eating less and moving more are not interchangeable, and neither figure accounts for what your body would have burned anyway.
Against a 2 000 kcal day it is about 21% of the day's energy.
These figures come from FatSecret US, not from the chain itself, and may lag its current menu. What lands on your tray varies with the branch, the build and the day.
