American Diet
Some of you may find this interesting. My girlfriend, who had never lived in the USA before, took a seasonal job for 3 months in California. She weighed 108 lbs when she started and gained a total of 20 lbs in the 3 months if you can believe that. I'm sure that some of it was water weight from huge amounts of sodium, however this should give you an idea of how we as Americans typically eat. It is hard to break those cultural behaviors that are ingrained in us.
ps. She quickly lost it when she returned home.
