The freshman fifteen can be a real phenomenon if you are not careful, even if you are not physically attending university but are using a site like onlineeducation.com to help you get your degree. Why? Plenty of reasons. For some people, puberty finally comes around and those fast metabolisms that they had as children and youth slow down a little bit. Suddenly you can’t eat a cheeseburger, fries, and chocolate shake every night before you go to bed and not see it show anywhere. This can happen and does happen without your noticing, this change in your metabolism. Suddenly one day you try to slip on your favorite pair of jeans and they no longer button up. You haven’t changed your eating habits one bit, it’s just that your body’s ability to metabolize all that food is different. And that means you might have to make some changes in what you eat.
For others, the change is not in metabolism, but is in the actual what and when of eating. When you lived at home, chances are you ate three meals a day and you were on a certain schedule. At school, you may be snacking throughout the day, as you go from class to class, you may be studying late into the night and food is the one thing that can get you through the night. You probably don’t take the time to prepare home-cooked meals, and so fast food becomes a fast friend (or, as the case may be, more of a foe).
Try taking a class that will make you work a bit. There are lots of recreation classes that you can attend that will keep you exercising at least three times a week. Also start to take note of how and what you eat. Just being aware of your habits can help you to change them.
