pretty simple, when you look at the back of a bag of any sort of food they have the ingredient info. how many calories, sugars, things like that; how do they know how much is in them?

In the past they would put their food in a measuring device, set it on fire, and figure out how hot it made everything.

Nowadays it’s more boring, they look up the calories of everything they put in and add them up.
