I found it amusing that stealing something was my victory, but please, let me explain...
I've been eating out of the same size bowls in the cafeteria all year and estimating the amount of food I put (or they dish) into them. I have usually estimated that up to the "lip" of the bowl is 0.8 cups, I don't really know why I thought 0.8 but I did.
Anyway, I stole a bowl from the cafeteria today (I'll return it, don't worry!) to see how much was actually in bowl so that I could more accurately use Fitday. (Really cracking down on my correct caloric intake woohoo.) I used my measuring cup and it was 0.8 to the lip!!! And 1.4 to the brim. So now I know.
All that baking must have paid off for eyeballing things. Yay.
