In the 1970s, we ate whatever we wanted, many of us worked desk jobs, drove cars, watched TV, read, or played cards in our free time. Kids ran around, but adults didn't, and only athletes joined a gym - and the huge majority of us were slim to normal weight without a struggle and often without any effort at all. In the late 1980s, millions of slim Americans started ballooning up in the pattern of a virus, as obesity spread across the nation and then much of the world. People's characters didn't suddenly change, but something did. Pinpoint what changed in the 1980s and identify what caused the obesity epidemic. Especially interesting are studies showing that mice with different gut bacteria can be fat or slim even on the same exact diet and exercise program.
