What that costs in movement
At 75 kg, this item is roughly 378 minutes of brisk walking or 196 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 107% of the day's energy.
The salt in it is about 330% of the 6 g adult daily reference intake.
These are the chain's own published averages for its market. What lands on your tray varies with the branch, the build and the day.
