The term "Freshman 15" is an expression commonly used in the United States and Canada to refer to weight gain during a student's first year in college. Although the 15 refers to a 15 lb. (6.8 kg) weight gain, the expression can apply to weight gain in general. In Australia and New Zealand, it is sometimes referred to as "First Year Fatties",[1] "Fresher Spread",[2] or "Fresher Five",[3][4] the latter referring to a gain of 5 kg (11 lb).
