Fatty Freshman Not So Fat!

I can't say that I am one of those freshman dealing with the freshman 15 process, but a friend of mine believe's she has become an statistic for freshman 15. She is very dramatic with this so called experience. Every five mintues she is commenting on how fat she think she is or how much weight she has gained. See, I definitely don't believe that my friend is any where near over weight/fat, but she tends to think otherwise. You can't tell her anything, she knows everything. I  have noticed that she is eating a lot of food during meal times and continues to have a lot of plates at our table, almost all is unhealthy for her. That still doesn't mean anything. I just see it as the girl just like to eat, but she isn't fat. I don't get why people assume just because they're gaining a few pounds that they're fat or over weight. It really doesn't make since. If you think you're fat then start exercising and make right choices at lunch, instead of talking and complaining about it all the time to your friends. I am sick of hearing about freshman 15 from girl's who are not even fat. I am trying to gain weight while other girl's are trying to lose weight. I realize that everyone has their own opinion about what is fat and what is not, but believe me if I could gain a few pounds I definitely would try whatever it takes, legally, but I can't my body tends to burn off the fat,instead of trying to keep the fat on. Freshman 15 is pretty common, but it's definitely avoidable for college students.
