Now that McDonald's doesn't supersize anymore do the customers just eat less, or do they order an extra order of fries?

Does anyone know? Tony Danza was just on the Joy Behar show and he was saying he agrees with Bloomberg wanting to limit soda size, because he thinks people eat and drink more if it is in front of them. I think he has a good point, even though I was not fond of Bloomberg’s idea, I see both sides.

But, this Q is not about Bloomberg and NYC, it is a simple curiousity if anyone knows of any studies done or statistics offered by McDonald’s about what consumers did after the change.
