They were really just making a fun comment about how good the food tastes...
If I had to guess, the pasta serving in the video was no more than about 150-200 calories. Dry pasta is 370 calories per 100g and pecorino is 390 per 100g. That serving was maybe 30g worth of pasta and maybe 10g worth of cheese.
Needless to say, that’s a snack-sized portion of pasta, not a meal.
There are few punishments more swift and severe than what happens after you express any opinion at all about Italian food on the internet.
Stim use is an effective appetite suppressant, after all.
