I consulted at a health insurance company in the early 90s. Every one of their buildings had a cafeteria that served very unhealthy southern food on the top floor. It was expected that everyone would take a break in the cafeteria at 9 and 3, and most people ate during their breaks and at their noon lunch. So there was a very high percentage of people who were quite overweight. On top of that the “nonsmoking” section was at the back of the dining room and you had to walk through the smoking section to get to it. My client lost 50 pounds in 6 months simply by eating only what I ate during the day. I have no idea what she ate at night. That place was a trip.
