The killer for me was breakfast cereals. The box shows a full bowl of whatever, full to the brim etc. in reality the pictures are probably 5 or 6 or more servings - a single serving would barely even cover the base of the bowl and even then be 200ish calories before milk.

If you just pour yourself "a bowl" of cereal without thinking or weighing then you're probably having 1200+ calories (or about 50% of your entire daily quota) even before you add milk or anything else, just for breakfast.

I don't know if they still do this, but I remember Special K cereal had identical calories listed for their various varieties, despite obvious differences in the ingredients; they just changed the portion size for each variety.

Cereal bowl sizes vary wildly, to make it even more confusing. Mine hold two cups (~450ml). Some hold way more than that. Some hold less. Buy a new set of bowls and you might be affecting your entire household’s eating habits.

You don't have to fill a bowl to the top with whatever you're eating lol

Well, no, but people do. The whole point of this thread is "people are bad at estimating quantity." If it looks the same size as it used to be, but in reality it's half again as big, that's going to have an effect.
