Short answer: Yes. As you transition from good-ol' high school to college, you'll experience a plethora of changes both physically and mentally; the freshman 15, sadly, is one of them. Now, don't get too discouraged because there are ways to avoid it:
1. Avoid stress as much as you can
Let's face it: there will be times where you'll feel overwhelmed by the magnitude of your coursework and other activities. It's completely normal. However, it is important to realize that high levels of the stress hormone, also known as cortisol, is related to an increase in cravings for junk food and appetite in general. So, take it easy and don't let stress take over your body.
2. Get Enough Sleep
Sleep is one thing you'll find hard to get in college. Ironically, it is one of the best ways to not only avoid freshman 15 but also have a successful school year. Sleeping solidifies one's memory and helps one in focusing on the task at hand. Make an effort to get adequate sleep.
3. Water is Key
Hydration is Major Key. Drinking water is linked to a healthier body as it helps in flushing out bacteria, lose weight and enhances your performance. Always keep a bottle of water with you.
4. Hit The Gym
Make an effort to go to the gym as often as you can. It not only helps you lose weight but also enhances your physique and relieve stress. Let's turn those freshman 15 into 15 lbs of muscles!
5. Embrace It
15 lbs isn't that big of a deal. Some people actually need to bulk up, so freshman 15 isn't really as horrific as it sounds. At the end of the day, you do you. Be happy about who you are and move on.
