I belive for most students (and the general population) it is an issue of what they are choosing to eat, rather than how much they are choosing to eat.
I find that following the Simple Diet article written here on T-Nation by Tim Henriques is a nice way to maintain healthy body fat levels. You're not going to be magazine cover ripped, but for the average bro like myself at 32 years of age, I find it a good balance of eating good food, having plenty of energy, staying strong, and not being a fat ass.
Now if you are an aspiring amateur bodybuilder or something, I apologize, I don't have any experience with that realm. Otherwise, unless you're competing in a sport, I personally don't find any reason to going into cut or bulk "phases." Just eating healthy and adjusting calories over time to reach your goals, I find, is the most beneficial method.
