I just came back to San Francisco from a week in Paris. The biggest surprise to me was how large the typical portion of food was at a restaurant. Everywhere from a tourist oriented charcuterie to a hipster joint in Montmartre. I told my friend they looked like American sized portions. Meanwhile the Bay Area never seemed all that obese to me. Leave the Bay Area and all of a sudden you'll see a surprising number of people so fat they can only move around in a motorized wheelchair.
