It is a good thing.... As a tourist! When I visited the US a couple of years back I was stunned by the food portions, but I knew I was only going to stay there for 2 weeks so I stuffed my face silly at every possible occasion. It is sad but "big" is a symbol of America and as a tourist you just enjoy it. Went back from 155 to 145lbs within a month after going back home (i'm 5'9) So yeah, when you see pictures like this of foreigners enjoying themselves with these "medium" portions: we're pretty much taking the piss out of America.
