The freshman 15 concept is not real, but is just commonly known because it can happen to a large group of people by coincidence. It is just a problem with a shift in lifestyle and depends on the person to adapt accordingly. I have many friends, including myself, who have lost weight in their freshman years simply because the food was unappetizing and our schedules did not allow a lot of free time for eating. On the other hand, some of my friends did gain the classic freshman 15, but it centered around other issues like high school athletes not being as active when not in college athletics.
