How often should I eat every day as a college student?

Eat at least every three hours (three meals and two snacks of fruit or veggies). This makes sure that you are fueled throughout the day so your body doesn't go into starvation-preservation mode. It also ensures that you won't be ravenous at any point in the day, making it less likely that you'll binge when you do eat or resort to eating something unhealthy just to put something in your stomach.
