North Americans refer to the weight that some college freshmen gain during their first year at university as the freshman 15. Those who believe in this "universal" 15-pound gain claim it is caused by lack of exercise, increased consumption of alcohol and low-nutrition food, and college-related stress.
However, several studies have debunked the notion that the freshman 15 is as common as many people think. While the average freshman does gain somewhere between 2 to 4 pounds during their first year of college, that's a far cry from 15.
