The Washington Post: “Do most freshmen really gain 15 pounds during their first year as undergrads? Research tells us no. Several studies have looked at the freshman 15 phenomenon and found that while weight gain is common during freshman year, 15 pounds is more than the average. The actual weight gain of freshmen varies greatly among different studies, with an overall average of 7½ pounds. A meta-analysis of studies examining the freshman 15 phenomenon found that although nearly two-thirds of students gain weight as freshmen, fewer than 10 percent gain 15 pounds or more.”
