This is a load of crap... When I went to college in NYC I lost about 20 pounds just from having to walk around everywhere. When I went I was 205 lbs when I came back I was 185. I ate completely horribly the entire time I was there; burger king, mcdonalds, cafeteria food, pizza, fries, an excessive amount of soda. In fact I eat worse than I did at home and still lost weight. The key walk a minimum of 1 mile a day.
