Because college students are always in class and on the go, skipping meals happens a lot. Many college students don’t know that skipping meals is bad for their health. Skipping meals causes you to be irritable, confused and weak. It can also cause a slowing of your metabolism which makes it hard to lose weight. To fix this you should eat protein snacks like granola bars that you can keep in your backpack. This helps make things easier to eat on the go.
