To be fair and balanced, I used to weigh everything when I was being super strict about my diet. I wanted to make sure I was hitting my macros exactly.

I would do shit like tare the scale with the bottle of olive oil on it, then add a few glugs to the pot, then weigh it again and write down how much I used. I'd do that with everything (even carrots) so that I would have a super accurate calorie/fat/protein count of the soup by the end.
