I usually make sure that I have at least a bowl of some granola food or substance even if it right before lunch. However, one of the best things that I realized is how I work late hours on the weekend so I have started to keep trail mix by the computer for TF2 sessions when I get home instead of eating twinkies and other fatty foods. Also, this is more of a personal choice, I stopped drinking energy drinks and soda for the extra few dollars towards computer parts but after the purchases I stayed away from them because of no longer have the sugar hang overs in the morning or needing a Monster to wake up to start my day. I drink a lot of water now and exercise to wake up. Also for those college students I found that if you have access to the kitchen there are simple pre-made dinners in a box that just require making dough(thats in the box) and cooking it with meat and vegies in a bowl for half an hour that make a balanced meal that can feed a person for a day or three students for a meal. Also for those late night cram sessions don't slam a bunch of soda try eating a bunch of fruit they can have the same amount of sugar in them for that quick burst of alertness as well as be good for you and your body.
