Eating after a certain time is given a bad rap mainly because people who eat late tend to overeat; meaning, you will eat a 500 calorie meal when you only have 100 calories left in your "calorie bank" for the day.
In theory, your body is less alert, and therefore less active after a certain time set by your individual circadian rythm. It is for this reason that certain people "naturally" cannot wake up early, regardless of when they go to bed. It is also for this reason that some people suggest you NOT eat after a certain time.
