Do you go for the early-bird special or wait to eat with the night owls? What time you wake up and go to bed surely comes into play here, as early risers are probably hungry earlier and most of us prefer not to eat right before bed. Those habits, as well as our body’s natural rhythms, are ultimately the biggest factors — well, that and where you’re from, as some parts of the world are known for eating late. As difficult as waiting until the appropriate time can be, avoiding a late-night snack hours afterward can be even harder.
