It's been years but I recall once reading an article that said that in the U.S., the average amount of weight gained for a traditional freshman (that is, 18 years old, just out of high school, enrolled full-time) was 6 lbs, and I think around an additional 3-4 lbs for sophomore year.
So, sorry to burst some bubbles.
Of course, that's an average. Some, lose weight.
Others, there's no statistically significant change.
And yeah, there's some who pack on a little, or even a lot.
What happens, and whether it does, likely depends on a great many things. The only constant is that transition from high school to college is a major one, where almost everything changes and disrupted.
Your day to day schedule changes dramatically. The town and where you live might have changed dramatically. Even the courses are different. If you have a job, that too is likely to be different. Even if you work at the same chain business, the layout of the store will be different as would be most if not all of your coworkers.
While there are other possible life events that might be comparable in terms of sheer disruption, these other events are not as likely to be experienced by most.
I feel this. I was 115 lbs all through college. Except for that one time I got sick and got down to 111. Do not recommend that.
I didn't put on anything until I was well out of college.
